Mississippi Postnuptial Agreement Overview
Mississippi recognizes postnuptial agreements under general contract law and the fiduciary duty framework between spouses. The Mississippi Supreme Court has held that agreements between spouses are subject to the same fiduciary standards that apply to other confidential relationships.
Mississippi follows equitable distribution principles for dividing marital property in divorce. Without a postnup, Mississippi courts have broad discretion in determining property division. A postnuptial agreement provides certainty for Mississippi couples.
Mississippi courts examine postnuptial agreements under the confidential relationship standard, requiring heightened fairness, full disclosure, and voluntary execution. Both spouses should have independent counsel.
