Elizabeth Escamilla filed for dissolution of marriage in Lee County in April 2024. Her husband, Dana, raised as an affirmative defense a 2007 premarital agreement, arguing it barred Elizabeth from seeking maintenance. The agreement waived each party's 'right, title or interests' in the other's 'property or estate' acquired by reason of the marriage but made no reference to maintenance, spousal support, or alimony. The trial court ruled the agreement constituted a valid waiver of both parties' rights to seek maintenance. Elizabeth appealed.

The Fourth District reversed on two grounds. First, the court held that statutory maintenance under the Illinois Marriage and Dissolution of Marriage Act is an important statutory right — rooted in the natural and legal duty of spousal support and in which the public has an interest — and therefore requires an explicit waiver. Second, the court held that the agreement's silence on maintenance, combined with its general waiver of property and estate interests, did not satisfy that explicit-waiver requirement. The court further reasoned that the Illinois Uniform Premarital Agreement Act itself separately enumerates property rights and spousal support as distinct subjects, confirming that a waiver of one cannot be read as a waiver of the other.

For family law practitioners, this decision establishes that premarital agreements in Illinois must expressly reference maintenance, spousal support, or alimony to effectively waive those rights. Boilerplate property waivers, even broad ones, will not suffice.
