A bill for an act authorizing spouses to amend premarital agreements, and including applicability provisions.

HF 616 allows Iowa spouses to amend their premarital agreements after marriage. The bill requires any amendment to be in writing and signed by both parties, while still following any specific amendment rules already included in the original agreement. This change applies to court proceedings involving amendments starting July 1, 2025. Currently, Iowa law only permitted revoking or enforcing premarital agreements, not modifying them.
