South Carolina Postnuptial Agreement Overview
South Carolina recognizes postnuptial agreements under general contract law principles and the fiduciary duty framework. South Carolina courts have upheld agreements between spouses as enforceable when they meet the heightened standards that apply to the confidential marital relationship.
South Carolina is an equitable distribution state under S.C. Code Section 20-3-620, where marital property is divided equitably considering fifteen statutory factors. A postnuptial agreement allows South Carolina couples to define their own division terms.
South Carolina courts apply the confidential relationship standard to postnuptial agreements, requiring heightened fairness, full disclosure, and voluntary execution. Both parties should have independent counsel.
