Rule in Wild's Case
The Rule in Wild's Case is a common law rule of construction dating back to 1599 concerning a particular type of ambiguity in devises (such as grants or bequests) of real property: If a grantor (O) grants, by deed or will, property to another person (A) with the language "To A and her children", who gets lawful possession of the property? The rule resolves this ambiguity as follows: If A has living children at the time of the grant, A and her children take the property as joint tenants.
