The postnuptial agreement violated California’s requirement that a contract have a “lawful purpose” and was therefore unenforceable. The article identifies another offensive provision that would have attributed matrimonial assets to the wife if the husband had used cocaine. In re Marriage of Mehren & Dargan, 118 cal. App. 4th 1167 (Cal. Ct. App. 2004). The article identifies Pennsylvania and Tennessee as “the only states in which courts have explicitly declared enforceable infidelity clauses, [as] both allow divorce on grounds of adultery.
