Domicile Act 1981

The Act relies on a limited set of principal concepts that structure domicile law for Western Australian purposes. Those concepts are defined or embodied in text that replaces or modifies the pre-existing common law.

• Domicile and domicile types. The Act operates with the existing common law taxonomy of domicile but modifies specific rules. The Act addresses two features commonly associated with domicile at common law: domicile of origin and domicile of choice. It abolishes the rule that domicile of origin revives automatically on abandonment of a domicile of choice (s 6). It also prescribes the mental element for domicile of choice as the intention to make home indefinitely in the country (s 9).
• Capacity to possess an independent domicile. The Act specifies who can have an independent domicile, using age and marital status as statutory thresholds. A person is capable of having an independent domicile if they have attained 18 years, or if they are or have at any time been married (s 7(1)). The Act preserves the existing common law disqualification where mental incapacity prevents acquisition of domicile (s 7(2)).
• Family-based attribution for children. The Act contains express rules for children’s domicile that attribute a child’s domicile to a parent’s in particular circumstances. Where a child’s principal home is with one parent while the parents live separately or the other parent is dead, the child takes that parent’s domicile and thereafter takes that parent’s subsequent domiciles (s 8(2)). Adoption substitutes parentage for domicile purposes with rules depending on whether the child has two adoptive parents or one (s 8(3)). The Act equally provides that a child retains a parent-derived domicile until acquiring a domicile of choice on reaching majority (s 8(5)), and it handles changing circumstances where the child’s principal home moves between parents or parents resume cohabitation (s 8(4)).
• Union or federation domicile. For persons domiciled in a union or federation but not in any particular member state under other rules, the Act resolves the question by reference to the closest connection with a constituent country (s 10). The Act expressly contemplates unions that may include the Commonwealth of Australia and treats the Commonwealth as a form of union for the defined term “union” (s 3).
• Evidence standard. The Act provides that evidence to establish acquisition of a domicile of choice in place of a domicile of origin may be the same as that which would be adequate if the prior domicile had been a domicile of choice (s 11). This addresses evidentiary parity between replacing one domicile of choice with another and replacing a domicile of origin with a domicile of choice.

Definitions in s 3 calibrate the statutory vocabulary. In particular, the definition of country includes constituent territories of a larger political unit where domicile in that territory can be material for Western Australian law, and union is explicitly defined to include the Commonwealth of Australia (s 3). The Act’s operational provisions state that after commencement the domicile of a person shall be determined as if the Act had always been in force (s 4(2)), while preserving pre-commencement determinations for times before the Act’s operation and preserving existing court jurisdiction over proceedings begun before commencement (s 4(1) and (3)).

Together these concepts reallocate legal decision points. The Act transfers certain determinations from residual common law rules to discrete statutory criteria, for example by removing marital automaticity for women’s domiciles and by codifying the child-parent domicile relationship. The statutory text does not create administrative registers, fees, or criminal offences; it works through judicial determination, evidence, and the private facts of domicile and residence.

The Act directly changes legal status and decision rules for a circumscribed set of persons and relationships, and indirectly affects practitioners and decision-makers who must apply domicile in statutory and private contexts.

Primary categories of persons affected under the Act text:

• Married persons. The abolition of the rule that a married woman has her husband’s domicile removes a legal presumption and changes the statutory capacity mechanics for married persons. The Act does not create a gendered substitute rule; it abolishes the previous common law rule unqualified (s 5). Married persons remain capable of an independent domicile under s 7(1)(b).
• Persons under 18 and married minors. The Act treats age and marital status as separate bases for capacity. A person aged 18 or over is expressly capable of independent domicile. A person who is, or has at any time been, married also has capacity to have an independent domicile even if not 18 (s 7(1)). Therefore minors who are or have been married are included within the statutory capacity to hold an independent domicile, subject to mental incapacity rules (s 7(2)).
• Children under 18 who are unmarried. The Act defines child as a person under 18 who is not and has not been married (s 8(1)(a)). For such children the Act ties domiciliary status to parental domiciles when the child’s principal home is with one parent and the parents are living separately or the other parent is dead, and sets rules on adoption, movement between parents and cessation of parent-derived domicile (s 8).
• Adopted children and adoptive parents. The domicile of an adopted child is determined by the adoptive relationships established: where adopted to two parents the child takes the domicile applicable to a child born in wedlock to those parents; where there is a single adoptive parent the child’s domicile is that parent’s at the time of adoption and thereafter follows that parent’s domicile (s 8(3)).
• Persons domiciled in unions or federations. Persons whose domicile is an aggregation of constituent countries and who are not domiciled in any particular constituent country under the common law as modified by the Act are assigned to the constituent country with which they have the closest connection (s 10).

Secondary affected groups and decision-makers:

• Courts and tribunals applying domicile. The Act explicitly modifies the common law and directs courts to apply the Act’s tests for domicile and its evidentiary standard (s 4(2), s 11). The Act also preserves pre-commencement jurisdiction for pending proceedings (s 4(3)).
• Lawyers, advisers and registrars whose work depends on domicile determinations. Any legal advice, filings, or determinations that require a person’s domicile for Western Australian law will need to follow the Act’s rules rather than the abolished common law rules. Practitioners advising on the domicile of children, adopted persons, married persons and persons moving between constituent parts of unions will be directly affected.
• Persons whose private rights or liabilities depend on domicile as a connecting factor. The Act applies to the exclusion of the laws of any other country relating to matters dealt with by the Act (s 4(4)). Where domicile is material to rights or obligations under Western Australian law, the statutory rules now control the domiciliary connecting factor.

The Act does not itself create new administrative costs, fees, or criminal sanctions. The burdens it imposes are those of establishing facts and evidence in court or administrative processes where domicile is in issue. The Act’s reallocation of presumptions,particularly the removal of a presumption tying a married woman to her husband’s domicile,alters who must present evidence and what evidence is determinative in disputes.

The Act does not impose positive statutory duties in the sense of obligations to perform or refrain from acts backed by specific statutory penalties. Instead it creates legal statuses, evidentiary rules and consequences that determine rights and obligations under other laws where domicile is a relevant connecting factor. The key operative rights and normative rules in the Act are:

• Right to an independent domicile. Individuals who meet the statutory capacity tests have the legal status of being capable of having an independent domicile. That capacity is granted by statute when a person has attained 18 years or is or has been married (s 7(1)). The statutory right is conditioned by mental incapacity rules in the common law, preserved by s 7(2).
• Removal of marital automaticity. The abolition of the rule that a married woman has the domicile of her husband (s 5) alters default allocation of domicile between spouses. The Act does not replace the abolished rule with a new presumption favouring one spouse; it removes the automatic attribution. This changes the normative baseline for allocating rights and obligations that depend on domicile: each spouse’s domicile must be determined on the Act’s terms rather than assumed from the husband’s domicile.
• Child domicile attribution. The Act confers on a parent, in specified circumstances, the operative legal effect of being the source of a child’s domicile. Where a child’s principal home is with one parent and the parents live separately or the other parent is dead, the child’s domicile is that parent’s and thereafter follows that parent’s domiciles (s 8(2)). The Act also provides that a child who had such a parent-derived domicile immediately before ceasing to be a child retains it until acquiring a domicile of choice (s 8(5)).
• Adoption consequences. On adoption the Act substitutes adoptive parentage for domicile purposes, either treating the adopted child as if born in wedlock to two adoptive parents (s 8(3)(a)), or attributing the single adoptive parent’s domicile at the time of adoption and thereafter following that parent (s 8(3)(b)). Where adoption is rescinded, the order rescinding the adoption may include domicile provisions; absent such provisions the Act directs that the child’s domicile is to be determined as if the adoption had not taken place (s 8(6)).
• Intention standard for domicile of choice. The Act prescribes the mental element required for acquisition of a domicile of choice, that is, the intention to make one’s home indefinitely in that country (s 9). This is a substantive standard that determines whether residence amounts to a change of domicile.
• Union domicile allocation. The Act gives persons domiciled in a union but not in a specific constituent country a substantive right to be treated as domiciled in the constituent country with which their closest connection lies (s 10). This is a determinative rule for persons whose situation would otherwise leave their domiciliary attachment indeterminate.

Procedural and evidentiary rules that affect how these rights are enforced:

• Transitional operation. The Act provides that domicile at times before the Act’s commencement is determined as if the Act had not been enacted, and after commencement as if the Act had always been in force (s 4(1)-(2)). This governs the temporal operation of the rights and statuses the Act creates.
• Evidence standard. Acquisition of a domicile of choice in place of a domicile of origin may be proved by the same kind of evidence that would suffice to establish a domicile of choice where the prior domicile was itself a domicile of choice (s 11). This reduces uncertainty about whether replacing a domicile of origin requires heightened proof.

Who decides. The Act presumes adjudication by courts or tribunals applying the modified common law; s 4(3) preserves court jurisdiction for proceedings commenced before commencement. The Act contains no administrative decision-making body or delegated decision power. The Act operates through judicial application of its definitions and rules in contexts where domicile is material.

The Act contains no provisions that create criminal offences, civil penalties or administrative fines. There are no express enforcement mechanisms contained in the statutory text to coerce compliance by private persons. Enforcement, insofar as domicile must be established or disputes resolved, is therefore procedural and judicial rather than punitive.

Key enforcement and implementation points drawn from the Act:

• Judicial determination as primary enforcement mechanism. The Act modifies the common law tests and provides evidentiary guidance. Determinations about who has which domicile remain matters for judicial or tribunal fact-finding in proceedings where domicile is in issue. The Act explicitly preserves the jurisdiction of any court in proceedings commenced before its coming into operation (s 4(3)) and provides that domicile after commencement is to be determined as if the Act had always been in force (s 4(2)), thereby instructing courts on the temporal application of the Act.
• No statutory penalties. The statutory text contains no penalty clauses. The Act therefore does not itself penalise failure to do anything or to make particular declarations about domicile. Any legal consequence for getting a domicile wrong will derive from the substantive law, private rights, contractual effects or judicial outcomes that use domicile as a connecting factor, not from direct statutory enforcement in the Domicile Act.
• Evidentiary guidance. The Act provides that acquisition of a domicile of choice in place of a domicile of origin may be established by the same class of evidence that would establish a domicile of choice if the previous domicile had also been a domicile of choice (s 11). This establishes an evidentiary norm for courts to apply when adjudicating disputes about acquisition of domicile of choice vis a vis domicile of origin.
• Scope exclusion versus foreign law. The Act states that it has effect to the exclusion of the application of the laws of any other country relating to any matter dealt with by the Act (s 4(4)). This means that, for purposes of Western Australian law, courts and decision-makers are to apply the Act’s provisions rather than relevant foreign domicile rules. Enforcement in cross-border cases will therefore involve applying the Act as the applicable law rather than deferring to another jurisdiction’s domiciliary rules.
• Procedural uncertainty and burden of proof. While the Act sets substantive tests and an evidentiary parity principle, it does not prescribe burdens of proof or procedural devices for how domicile questions are to be litigated. Those procedural matters remain for courts and civil procedure rules. The Act therefore leaves to adjudicators the everyday task of allocating burdens and assessing the sufficiency of evidence under the standards set out.

In short, enforcement is decentralised to judicial and quasi-judicial processes rather than administered through statutory sanctioning. The Act changes the substantive determinations courts must make and supplies evidentiary guidance, but does not create a dedicated enforcement regime.

The Act explicitly situates itself in relation to common law and foreign law and therefore determines how domicile questions interact with other legal regimes that use domicile as a connecting factor.

Primary interactions provided in the Act:

• Modification of the common law. The Act operates as a statute that abolishes and modifies specific common law rules (for example, the dependent domicile of a married woman and the rule of revival of domicile of origin) and otherwise leaves the common law in force (see s 5 and s 6). Section 10 explicitly applies the rules of common law as modified by this Act when determining domicile in a union. The Act therefore must be read together with the remaining common law rules of domicile; it does not purport to be a complete codification.
• Temporal interplay. The Act contains temporal rules that state domicile at times before commencement is to be determined as if the Act had not been enacted, while domicile after commencement is to be determined as if the Act had always been in force (s 4(1)-(2)). This directs courts and decision-makers dealing with events or rights that span the commencement date how to apply either the pre-existing common law or the Act’s modified rules.
• Exclusion of foreign law on matters the Act deals with. Section 4(4) is explicit: the Act has effect to the exclusion of the application of the laws of any other country relating to any matter dealt with by this Act. For questions of domicile that are material for the purposes of Western Australian law, that provision directs courts not to import another country’s rules on these same matters. This is a conflict-of-laws rule that locates the Act as the controlling domestic law for the matters it addresses.
• Interaction with family law and adoption orders. The Act takes account of adoptive relationships and parental residence in allocating children’s domicile (s 8). The Act directs that where adoption is rescinded, the domicile shall thereafter be determined in accordance with any provisions included in the order rescinding the adoption, and otherwise as if the adoption had not taken place (s 8(6)). This explicitly yields to family court orders that include domicile provisions in rescission orders, indicating an interface between the Act and judicial family law orders where adoption rescission is concerned.
• Evidence and proof in other statutory contexts. Where another statute or legal process depends on a person’s domicile, the Act’s tests and s 11’s evidentiary rule will be relevant to proof of domicile. The Act does not prescribe which institutions must accept particular documentary proofs, nor does it create administrative registries, so procedures for proving domicile in other legal contexts remain subject to those other statutes, rules of evidence and administrative practices, with the Act determining the substantive test to be met.

Constraints and limits in the Act’s interaction with other laws:

• Not an exhaustive codification. The Act modifies and abolishes particular common law rules, but it does not replace the common law in toto. Where the Act is silent the common law (subject to the modifications the Act makes) remains relevant. Section 10’s reference to the common law as modified by the Act makes this interaction explicit.
• No domestic administrative implementation regime. The Act contains no administrative framework for registering domicile or making determinations outside court. Interaction with other statutory regimes that require a domicile will therefore be through judicial adjudication and evidence rather than administrative certification established by this Act.

Overall, the Act frames domicile as a subject of domestic statutory control for Western Australian purposes, limits reliance on foreign domiciliary laws for the matters it covers, and modifies particular common law presumptions and rules so that other laws and processes that depend on domicile will need to apply the Act’s standards.

The statutory text supplied contains a compilation table and reprint information that records the Act’s passage and reprints. The table records the following points of legislative history as presented in the supplied material:

• The Domicile Act 1981 is recorded as number 91 of 1981, with assent on 26 November 1981.
• The Act’s commencement is recorded as 1 July 1982, under section 2 and the Western Australian Government Gazette dated 25 June 1982 at page 2114 (Compilation table; s 2).
• The compilation notes record a reprint as at 2 August 2002 and a second reprint as at 8 May 2015. The front matter identifies the reprint "Reprint 2: The Domicile Act 1981 as at 8 May 2015."

The provided compilation table and reprint notes do not list any amending Acts, schedule alterations or textual amendments between the original enactment and the reprint dates included in the supplied material. The material provided is a reprint compilation as at 8 May 2015 and accordingly shows the consolidated text as of that date.

What the compilation material does not supply:

• The compilation table in the supplied text does not list any amending legislation or identify subsequent changes to the Act’s text. It records only the original Act’s particulars and the dates of reprints.
• Because the reprint entries are compilation notes, they do not themselves constitute amendment history beyond the fact of reprinting. The supplied material does not include a schedule of amendments, notation of sections added or repealed by later Acts, or footnotes reflecting textual changes. Therefore the supplied source does not record any specific amending instruments to describe here.

Practical consequence for advisers and researchers:

• Use the reprint date. The reprint as at 8 May 2015 contains the consolidated text that an adviser or researcher should treat as the statutory text available in the supplied material. If a practitioner requires knowledge of any amendments postdating that reprint they must consult the official statute reprints, parliamentary records, or consolidated legislation databases beyond the supplied document.
• Rely on the Act’s internal commencement and transitional provisions for temporal questions. The Act itself states that it comes into operation on a day fixed by proclamation (s 2), and the compilation table records the actual commencement by Gazette notice on 1 July 1982.

In sum, the supplied material documents the Act’s original enactment and reprint dates but does not record any amending legislation in the compilation table provided. Any inquiry into amendment activity after the reprint date must proceed to external legislative records.

The supplied statutory text and compilation notes do not include case references, reported decisions or any litigation history applying the Domicile Act 1981. The Act as reproduced in the supplied material contains no footnotes or annotations that identify judicial treatment, nor does the compilation table supply litigation citations.

What follows from the source material:

• No cases are named or cited in the supplied text. The Act itself does not reference judicial decisions.
• The supplied reprint includes only the statutory compilation and reprint information; it does not provide a history of how courts have interpreted or applied the Act.

Practical implications for research and litigation strategy:

• Courts remain the forum for resolving domicile disputes. The Act supplies the substantive rules and evidentiary guidance (for example s 11), and it preserves existing judicial jurisdiction for proceedings already commenced at commencement (s 4(3)). However the supplied material does not show how courts have applied the Act’s provisions to concrete fact patterns.
• Evidence-based adjudication. The Act’s s 11 provides an evidentiary principle for establishing acquisition of domicile of choice in place of a domicile of origin. In litigation, parties will need to adduce the relevant factual evidence to meet the court’s assessment under the Act’s standards.
• Research required. To understand judicial approaches to applying s 5 (abolition of dependent domicile), s 6 (abolition of revival of domicile of origin), s 8 (children’s domicile), s 9 (intention standard), s 10 (union domicile) and s 11 (evidentiary guidance), a practitioner must consult case law external to the Act text supplied here. The supplied material does not provide that case law.

Because the statutory source provided contains no litigation history, any practitioner or researcher requiring precedent must search the reported decisions and tribunal determinations that have considered the Act since commencement and reprint. The Act itself designates the legal standards that courts should apply, but the supplied materials do not contain records of how those standards have been operationalised by courts.

The Act is short, but its brevity creates a number of points where the statutory text yields outcomes that may be counterintuitive unless one reads the particular wording carefully. The following are concrete textual points that commonly give rise to issues in practice, with the section citations that create the point of potential difficulty.

• Abolition of dependent domicile is absolute (s 5). The Act abolishes the rule that a married woman has the domicile of her husband. The text does not create a replacement presumption or transitional rule allocating spouses’ domicile. Practitioners should not assume the old marital automaticity remains in any modified form. Where matters previously relied on that presumption, parties will need to present evidence to establish each spouse’s domicile under the Act and the surviving common law rules.
• Capacity by marriage irrespective of age (s 7(1)(b)). The Act grants capacity to have an independent domicile to a person who "is, or has at any time been, married." Read literally, this includes persons who have been married at any time, even if they are still under 18. The combined effect of s 7(1)(a) and (b) means there are two statutory paths to capacity: attainment of 18 years, or marital status. The Act preserves the common law incapacity rule for mental incapacity (s 7(2)). Practitioners should check whether a client’s marital history creates capacity even where age might otherwise suggest incapacity.
• Continuation of existing domicile until acquisition of a different one (s 6). The Act abolishes the rule that domicile of origin revives on abandonment of domicile of choice, and instead provides that a person’s current domicile continues until they acquire a different domicile (s 6). Practically, this means that abandonment of residence without a demonstrated new domicile will not revert a person automatically to their domicile of origin. That alters the mechanics of proof in contested cases where a party claims that a person has reverted to an earlier domicile.
• Child’s domicile follows parent where principal home is with one parent while parents live apart or the other parent is dead (s 8(2)). The rule is conditional on principal home plus parental separation or the other parent’s death. The Act defines child narrowly as a person under 18 who has not been married (s 8(1)(a)). Therefore the presence or absence of a child’s "principal home" and whether parents are "living separately and apart" are fact questions that will determine the child’s domicile. Practitioners should document arrangements of principal home and parental status.
• Retention of parent-derived domicile until the child acquires a domicile of choice (s 8(5)). Where a child had a domicile by virtue of s 8(2) or (3) immediately before ceasing to be a child, the child retains that domicile until they acquire a domicile of choice. The point at which a person has acquired a domicile of choice is governed by the intention standard in s 9. This creates a two-step proof: first the parent-derived domicile, then potential acquisition of domicile of choice after majority.
• Adoption and rescission order details (s 8(3) and (6)). On adoption the Act attributes domicile in different ways depending on whether there are two adoptive parents or one. If an adoption is rescinded, any domicile provisions included in the rescission order control; otherwise the child’s domicile is to be determined as if the adoption had not taken place. Where a rescission order omits domicile provisions the default is to treat the adoption as never having occurred for domicile purposes. Consequently, parties should consider including domicile provisions in rescission orders when seeking rescission.
• Intention expressed as "indefinitely" (s 9). The Act requires the intention to make one’s home indefinitely in the country for acquisition of a domicile of choice. Courts will need to assess whether the person’s intention meets that standard, but the Act does not provide a checklist. Practitioners should compile contemporaneous evidence of intent to make home indefinitely where domicile of choice is relevant.
• Union domicile decided by "closest connection" (s 10). The Act supplies a tie-breaking rule for persons domiciled in a union or federation but not a constituent country. The standard is the closest connection, a fact based inquiry. The Act also contemplates that "union" includes the Commonwealth of Australia (s 3). Parties with ties across constituent parts of a federation should map factual connections to the constituent country level.
• Exclusion of foreign law for matters the Act deals with (s 4(4)). The Act instructs that it applies to the exclusion of other countries’ laws on the same subjects. This is a conflict-of-laws rule and has implications for cross-border litigation and status determinations. Practitioners dealing with international elements should note that Western Australian law as stated in the Act is to be applied, not a foreign domiciliary rule, for matters covered by the Act.

Each of these points follows directly from the statutory language. They create practical areas where factual evidence and legal argument must be concentrated because the Act either removes an old presumption, changes the default rule, or leaves a matter to judicial assessment without specifying a procedural framework.

The Act does not create reportable statutory obligations or administrative filing requirements. Compliance therefore consists of meeting the substantive standards and evidentiary thresholds the Act sets when domicile is relevant for a legal purpose under Western Australian law. The following practical measures derive from the Act’s text and indicate what parties and practitioners should document and how they should approach domicile issues.

1. Identify the relevant statutory tests and timing.

   • For events before the Act’s commencement use the pre-Act common law rules; for events after commencement apply the Act as if it had always been in force (s 4(1)-(2)). Confirm the relevant date for the legal question at issue.
   • Where proceedings were commenced before the Act came into operation, the court’s jurisdiction is preserved for those proceedings (s 4(3)).

2. For adults claiming a domicile of choice, establish the intention standard.

   • The Act requires the intention to make one’s home indefinitely in the country to acquire a domicile of choice (s 9). To meet that standard gather contemporaneous and objective evidence that supports the assertion of an indefinite home, such as long-term housing commitments, employment, family ties, registrations, tax residence, and other indicia that show permanence.
   • Remember that the evidentiary rule in s 11 allows acquisition of a domicile of choice in place of a domicile of origin to be established by evidence that would be sufficient if the previous domicile had been one of choice. Do not assume a higher standard is required when the previous domicile is a domicile of origin.

3. For married persons, do not assume automatic attribution of domicile.

   • Since the Act abolishes the rule that a married woman has her husband’s domicile (s 5), each spouse’s domicile must be established on the statutory and modified common law criteria. Do not rely on spousal domicile presumptions.

4. For minors and married minors, establish capacity.

   • The Act grants capacity for an independent domicile to persons aged 18 and over and to persons who are or have been married (s 7(1)). For a client who is a married minor, document the marital status and consider whether mental incapacity under common law rules is an issue (s 7(2)).

5. When a child’s domicile is in issue, document principal home and parental status.

   • If a child’s principal home is with one parent and the parents live separately and apart or the other parent is deceased, the child’s domicile is that parent’s and thereafter follows that parent’s domicile (s 8(2)). Record custodial arrangements, living arrangements, parenting orders, and any court orders that allocate principal home.
   • If advising on adoption, note that an adopted child’s domicile is determined by the adoptive arrangement: two adoptive parents produce a treat-as-born-in-wedlock result; a single adoptive parent produces the parent’s domicile at time of adoption and thereafter that parent’s domiciles (s 8(3)). Where adoption is rescinded, include domicile provisions in the rescission order if parties want a specific domiciliary outcome (s 8(6)).

6. For persons domiciled in unions, map closest connections.

   • If an individual is domiciled in a union but not in any specific constituent country under other rules, determine the constituent country with the person’s closest connection and document the factual matrix that demonstrates that connection (s 10). Evidence should address residence, family, business, property, and social ties to constituent parts.

7. Prepare evidence to the s 11 standard.

   • The Act permits evidence establishing acquisition of a domicile of choice in place of a domicile of origin to be the same as that which would be sufficient if the previous domicile had been a domicile of choice (s 11). Focus on the same classes of evidence you would collect to prove a domicile of choice generally.

8. Consider the Act’s exclusionary clause in cross-border matters.

   • Section 4(4) directs that the Act applies to the exclusion of foreign law for matters it deals with. When a client’s matter involves foreign elements, prepare submissions that apply the Act’s rules rather than invoking foreign domiciliary doctrines, and be prepared to explain why Western Australian statutory tests should control for the purposes of the domestic legal matter.

9. Document decisions and facts contemporaneously.

   • Because the Act leaves important matters to factual inquiry and judicial assessment, contemporaneous documentation of residence intentions, principal home arrangements, adoptions, rescissions, and marital status will materially assist in establishing domicile under the statutory tests.

10. Consult relevant procedures and case law.

• While the Act sets substantive tests and evidentiary guidance, it does not set procedural rules. Practitioners should consult civil procedure rules, evidence law and judicial authorities that apply the Act for procedural guidance in how courts have assessed evidence and allocated burdens.

The Act places the legal work on evidencing facts and intentions rather than complying with administrative formalities. Compliant practice therefore focuses on careful fact-gathering, contemporaneous documentation of intent and home arrangements, and preparing legal argument that applies the Act’s standards for capacity, child domicile, adoption consequences and union domicile.
