Legal Ouster Law and Legal Definition

Legal ouster is the removal of a person from the possession of a land by due process of law. For example, eviction of a tenant.

The effect of legal ouster was discussed in the following case. "Where a legal ouster occurs, an actual or constructive ouster, and possession is taken under a hostile claim, a continued, uninterrupted, adverse possession for the statutory period, under color of title or claim of right, works an absolute bar.” [In Clarke v. Dirks, 178 Iowa 335, 347 (Iowa 1916)].
