William Zurenda was disabled by post-traumatic stress disorder (PTSD), but had not been adjudged mentally incompetent. During divorce proceedings, he agreed to pay his spouse $5,000 within six months. The settlement was read aloud in court, and the judge asked William if he understood that the settlement was binding. He answered that he did. Later, he argued that he should not have to pay the $5,000, because the stress of the divorce had made his PTSD worse. Is the settlement void on the basis of mental incompetence? Explain. [Zurenda v. Zurenda, 85 A.D.3d 1283, 925 N.Y.S.2d 221 (3 Dept. 2011)]
