Intrusion

Intrusion, the entry of a stranger after a particular estate of freehold is determined before him in reversion or remainder. Where a tenant for life dies seized of certain lands or tenements, and a stranger enter thereon after such death of the tenant, and before any entry of him in remainder or reversion, such stranger is called an intruder. Intrusion was one of the five modes, the others being disseisin, abatement discontinuance and deforcement, which constituted adverse possession, from which time was computed under the old Limitation Acts.

The writ of entry on intrusion is abolished by the (English) Real Property Limitation Act, 1833 (3 & 4 Wm. 4, c. 27).
