Per Tout Et Non Per My Law and Legal Definition

Per tout et non per my is a phrase from French law which means “By the whole and not by the half.” This phrase describes the type of seisin that exists in a joint tenancy or tenancy by the entirety. The joint tenants or husband and wife who own property by the entirety own an undivided interest in the whole of the property but not an individual interest in half the property. In a tenancy by the entirety one spouse cannot seize or end the tenancy by his or her acts alone.
