A premarital agreement is presumed valid unless the challenger proves procurement through fraud, duress, mistake, misrepresentation or material nondisclosure; unconscionability; or sufficiently changed circumstances.
MacFarlane v. Rich, 132 N.H. 608, 567 A.2d 585 (1989); In the Matter of Nizhnikov, 168 N.H. 525 (2016)New Hampshire material-nondisclosure ground

In the Matter of Nizhnikov, 168 N.H. 525 (2016)New Hampshire financial-knowledge evidence

Practical examples
These examples show how document facts can intersect with the cited sources. They do not predict a court result.
The fixed future child-payment clause
A draft fixes future child-related payments without regard to later circumstances. New Hampshire's statutory child-rights limitation makes that clause a mandatory counsel-review item.N.H. Rev. Stat. Ann. § 460:2-a
Ask local counsel
Which child-related terms, if any, can a court consider without abrogating the child's rights?
The written side letter
The parties sign a short side letter after the main agreement. The writing statute identifies form, but current cases must determine how the documents interact and whether the later paper changes the bargain.N.H. Rev. Stat. Ann. § 460:2-a
Ask local counsel
Does the side letter qualify as an effective contract or amendment under current New Hampshire law?
