Seisin in Law Law and Legal Definition
Seisin in law is the right to immediate possession of land under a freehold title.
In seisin in law there will be only a bare right to possess. In contrast, in seisin in deed there will be actual possession. [Stoddard v. Gibbs, 23 F. Cas. 126, 128 (C.C.D.R.I. 1832)].
To constitute a seisin in law there must be a right of immediate possession according to the nature of the interest, whether corporeal or incorporeal. There can be no seisin in law where there is not a present right of entry. [Carlson v. Sullivan, 146 F. 476, 478 (9th Cir. Alaska 1906)].
