5. c. 21) was an act of Parliament in the United Kingdom that codified, prioritised and extended the system of land registration in England and Wales.

After the Land Registry Act 1862 and further attempts in 1875 and 1897 failed, as they either tried to register everything or largely relied on voluntary registration, the 1925 Act was drafted to ensure a more complete, but progressive system.

One of the most important provisions was that if someone had not registered the interests listed in section 70, these would nevertheless "override" the rights of a future purchaser.

The occupant would have priority over future purchases without his consent, as if his interest had been in fact registered.
