Property Law Act 1969

In any instrument coming into operation after the coming into operation of this Act, a limitation which, if this section had not operated would have created an estate tail (legal or equitable) in any land in favour of any person shall be deemed to create an estate in fee simple (legal or equitable, as the case may be) in that land in favour of that person to the exclusion of all estates or interests limited to take effect after the determination or in defeasance of any such estate tail.

Where at the coming into operation of this Act any person is entitled to an estate tail (legal or equitable), whether in possession, reversion, or remainder, in any land, that person, except as hereinafter mentioned in this section, shall be deemed to be entitled to an estate in fee simple (legal or equitable, as the case may be) in that land, to the exclusion of all estates or interests limited to take effect after the determination or in defeasance of any such estate tail.

In subsection (2) the expression estate tail includes that estate in fee into which an estate tail is converted where the issue in tail is barred, but the persons claiming estates by way of remainder are not barred; also an estate in fee voidable or determinable by the entry of the issue in tail; but does not include the estate of a tenant in tail after possibility of issue extinct.
