A significant alteration in a party's position, duty, meaning conveyed, or circumstances that affects legal rights or obligations, particularly when made in reliance on a promise, statement, or agreement.
After Morgan Financial told Marathon Logistics it would not deliver goods by the agreed date, Marathon began sourcing replacements from another supplier at higher cost. Morgan then notified Marathon that it would perform after all. Marathon refused and sued for repudiation. Because Marathon had already shifted its sourcing plans before receiving the retraction, the retraction did not nullify the repudiation.
A reporter interviewed Maya Malik and later published an article attributing a quotation to her that rearranged her words to suggest she had admitted to fraud. Malik sued the publication for defamation. The court examined whether the rearrangement produced a different meaning from her actual statements. Because the alteration changed the conveyed meaning, it supported a finding of actual malice.

Momentum Capital assigned its right to receive payment under a supply contract with Mirage Hotels to a third party. The assignment required Mirage to provide detailed weekly reports and accept variable delivery schedules never required before. Mirage refused to perform for the assignee. The assignment was ineffective because it materially changed Mirage's duties and increased its burden under the contract.
Musa Mensah and Melissa Mills signed a premarital agreement waiving spousal support. Five years after marriage, Musa suffered a permanent disability that prevented him from working and left him eligible for public assistance. Melissa sought to enforce the waiver. The court refused enforcement because the disability created a material change in circumstances producing substantial hardship.
Madison Meyers promised Marco Marquez an extra payment if he completed additional construction work after an unexpected regulatory change. Relying on the promise, Marquez hired extra workers and turned down other jobs. Meyers later refused the extra payment. The modification was enforced to the extent justice required because of Marquez's material change of position in reliance.
Megan Moore and Momentum Capital orally agreed to modify a year-long services contract by adding new deliverables. The modification was unenforceable under the Statute of Frauds. Moore had not yet hired additional staff or declined other work in reliance on the oral change. The prior contract therefore remained unmodified.
A change counts as material when the injured party has taken concrete steps such as sourcing replacements or incurring new obligations before receiving notice of retraction. The retraction then fails to nullify the repudiation.

An assignment is ineffective if it would materially change the other party's duty, increase its burden or risk, or impair its chance of return performance. New reporting requirements or variable performance demands can trigger this bar.

A court may refuse enforcement of a term if a material change in circumstances after signing would cause substantial hardship to a party. The change must arise after the agreement and be evaluated in the context of the whole agreement.
Supporting sources
Deliberate alteration supports actual malice only if it results in a material change in the meaning conveyed by the statement. Trivial changes that leave the meaning substantially accurate do not suffice.
Supporting sources
A modification is binding to the extent justice requires when a party materially changes position in reliance on the promise. Hiring additional staff or declining other opportunities can satisfy this standard.
