A material alteration in the facts or conditions existing after formation of an agreement or entry of a decree. The alteration may justify a court in refusing enforcement of a contractual term or modifying a support or maintenance order when the change produces substantial hardship or renders original terms unconscionable.
After signing a premarital agreement that waived spousal support, Christine Castro lost her long-term job due to industry collapse and could no longer meet basic living expenses. She petitioned the court to decline enforcement of the waiver. The court examined whether the post-agreement job loss created substantial hardship under the agreement taken as a whole.
Carmen Choi obtained a divorce decree requiring her former spouse to pay monthly maintenance. Two years later her former spouse suffered a permanent disability that eliminated his income. He moved to reduce the obligation. The court required proof that the disability constituted changed circumstances so substantial and continuing as to render the original terms unconscionable.

Cody Callahan challenged a state abortion restriction under the undue burden standard. He argued that medical advances and new data on clinic capacity since the original ruling constituted a change in circumstances.

Clifford Cox sued to invalidate removal protections for members of an accounting oversight board.

The court weighed whether those facts altered the constitutional balance between parental rights and third-party visitation.
Charlotte Chung, a clinic operator, sought to enjoin new state restrictions on abortion facilities. She presented evidence that clinic closures and increased travel distances since prior litigation amounted to a change in circumstances. The court considered whether those developments rendered the restrictions unconstitutional under the applicable standard.
The party must demonstrate that the change is substantial and continuing and that enforcement of the original terms has become unconscionable. Courts confine review to events arising after the decree and do not revisit the original fairness of the award.
