Estin Doctrine Law and Legal Definition

This term is commonly used in family law in the context of divorce proceedings. The Estin Doctrine states that although full faith and credit is given to a divorce decree in terminating a marriage, a spousal support provision may not be recognized by another court unless the court entering the order had jurisdiction over both spouses. The Court in which a divorce decree is enforced has to have jurisdiction over both the spouses in order to recognize a spousal support provision.
