Signing Requirements
Both parties must sign the agreement and it is recommended, although not required, that a notary public sign as well.[1]
Laws
§ 767.61(3)(L) – Property Division – Presumption of Equal Division.
Case – In re Marriage of Button v. Button, 131 Wis. 2d 84 (1986)
…an agreement is inequitable…if it is unfair either in its procurement or in its substantive provisions.
Fairness in procurement depends on two factors: whether each spouse makes fair and reasonable disclosure to the other spouse of his or her financial status, and whether each spouse enters into the agreement voluntarily and freely.
