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:
This rule has fallen into disuse in those jurisdictions which no longer recognize the fee tail as a legal estate. Some U.S. states ignore the rule altogether, and interpret such a grant as giving a life estate and creating a remainder in her children. Section 14.2 of the Restatement (Third) of Property repudiates the Rule in Wild's Case, suggesting that many authorities consider it to be obsolete.
