Uniform Premarital Agreement Act Law and Legal Definition

The Uniform Premarital Agreement Act was promulgated by the National Conference of Commissioners on Uniform State Law (NCCUSL) in 1983. This act provides a more certain framework for complete and enforceable premarital agreements. According to UPAA, a premarital agreement is defined as "an agreement between spouses made in contemplation of marriage and to be effective upon marriage." Such agreements are valid if made in writing and signed by both parties. They are effective upon marriage and do not need consideration.

Many states in the U.S. have adopted the act. Mississippi, Missouri, South Carolina and West Virginia adopted it in 2010.
