Illness Triggers Hardship Review
Mohan Malhotra and Miranda Morales signed a premarital agreement waiving spousal support. Ten years later Miranda developed a rare autoimmune disease that left her unable to work while Mohan's royalty income surged. In the divorce the court refuses to enforce the waiver because the post-signing illness and income disparity create substantial hardship.
Income Shift Supports Modification
Monica Morgan obtained a support decree based on her then-modest farm income. After a severe drought she inherited additional land and began receiving sizable federal subsidies that increased her resources. She petitions for downward modification, asserting that the new income stream constitutes a material change in circumstances rendering the original terms unconscionable.

Health Decline Alters Support Terms
Maya Malik signed a premarital agreement waiving support while healthy and employed. Years later a chronic back condition from nursing left her unable to work and facing poverty if the waiver is enforced. The court declines to enforce the waiver because the post-agreement medical change produces substantial hardship.
Grandparent Visitation Order Reviewed
Mina Mehta obtained a grandparent visitation order when the parents' relationship was stable. After the parents' acrimony grew and the child entered school the grandparents seek modification. The court requires a showing of material change in circumstances before altering the order.
Clinic Regulations Face New Facts
Ming Ma operated a clinic under a regulatory decree imposing certain operational requirements. After a statewide health emergency altered patient volumes and supply costs she moves to modify the decree. The court examines whether the emergency constitutes a material change in circumstances making continued enforcement unconscionable.
Farm Income Fluctuation Examined
Momentum Capital held a support decree calculated from seasonal farm revenue. After receiving unexpected federal subsidies and selling a partnership interest the obligor petitions for reduction. The court assesses whether the new income sources amount to a material change in circumstances sufficient to render the original award unconscionable.
Common questions
Frequently Asked
4
How does a material change in circumstances differ from unconscionability at the time of signing?+
Unconscionability is assessed at execution. A material change in circumstances arises afterward and can independently justify refusing enforcement of a term even if the agreement was valid when signed.
Supporting sources
What must a party show to modify a support decree under the changed-circumstances standard?+
The party must demonstrate changed circumstances so substantial and continuing that the original terms have become unconscionable. Mere fluctuations in income or ordinary market risks usually do not suffice.
Supporting sources
Can a court refuse to enforce only part of a premarital agreement based on later hardship?+
Yes. The statute permits a court to decline enforcement of a specific term that would cause substantial hardship because of a material change in circumstances while leaving the remainder of the agreement intact.
Supporting sources
Does an increase in the obligor's income alone constitute a material change in circumstances?+
Not necessarily. The increase must be substantial and continuing and must render enforcement of the existing order unconscionable when viewed against the parties' overall financial positions and the child's needs.
