4 Extent of the estate created by a tenant in tail by way of mortgage or for any other limited purpose

If a tenant in tail of lands shall make a disposition of the same under this Act by way of mortgage, or for any other limited purpose, such disposition shall, to the extent of the estate thereby created, be an absolute bar in equity as well as at law to all persons as against whom such disposition is by this Act authorized to be made, notwithstanding any intention to the contrary may be expressed or implied in the deed by which the disposition may be effected: Provided always that, if the estate created by such disposition shall be only an estate pour autre vie, or for years absolute or determinable, or if, by a disposition under this Act by a tenant in tail of lands, an interest, charge, lien, or encumbrance shall be created without a term of years absolute or determinable, or any greater estate, for securing or raising the same, then such disposition shall in equity be a bar only so far as may be necessary to give full effect to the mortgage, or to such other limited purpose, or to such interest, lien, charge, or encumbrance, notwithstanding any intention to the contrary may be expressed or implied in the deed by which the disposition may be effected.
