where they continue to live together as husband and wife, which is expressly prohibited.
84
But the
authority from elsewhere makes clear that continuing cohabitation is no requirement for this bar; an
agreement purporting to terminate duties of support – or liability for attorney’s fees – between
parties who are still married is void ab initio,
85
the little Nevada authority that exists certainly
appears to support the same conclusion,
86
and if an agreement purports to be an integrated agreement,
that invalidity renders the entire agreement unenforceable.
87
In short, an agreement purporting to be a postnuptial agreement cannot contain any terms relating
to spousal support, because spouses may not enter into a postnuptial agreement limiting one spouse’s
duty of support to the other.
88
Postnuptial agreements are typically framed as contemplating indefinite continuation of a marriage,
or of reconciliation if the parties had already separated,
89
rather than confirming that parties had or
were about to separate, or explicitly speaking of a divorce filing or that the parties had adverse
interests. Such agreements, even if titled uncertainly, would classify as postnuptial agreements.
As noted above, most authorities conclude that a valid postnuptial agreement must have the same
disclosures required in a premarital agreement. Failure to provide, at the time of signing, at least the
disclosures and waivers that would support a premarital agreement should render a postnuptial
agreement unenforceable, for the same reasons.

ON SEPARATION AGREEMENTS AND ANTENUPTIAL CONTRACTS § 110.69[4] (1999) (“the cases are clear that the parties
cannot agree to terms relieving one or the other, or both, of legal spousal support obligations during the marriage”).

Dimick v. Dimick, 112 Nev. 402, 915 P.2d 254 (1996) (prenuptial agreement provisions governing support
are “separate entirely from the order for temporary support issued by the court during the divorce proceedings”).
87
Cord v. Neuhoff, 94 Nev. at 24, 573 P.2d at 1172.
88
See Cord v. Neuhoff, 94 Nev. 21, 24 n.3, 573 P.2d 1170, 1172 n.3 (1978); Dimick v. Dimick, 112 Nev. 402,
915 P.2d 254 (1996). Cord spoke to a couple “continuing to live together as husband and wife” but it is doubtful that
either of those specifics (cohabitation or opposite-sex relations) have any importance to the holding today; if either, it
is cohabitation, but while the statute makes it clear that for a separation agreement to be valid the couple must actually
separate, the logic is less clear as to why parties to a postnuptial agreement must continue to cohabit.
89
Apparently, the Jones v. Jones Jr. case discussed above had exactly those facts – parties that had separated,
and then reconciled. The case law contains several such instances. See, e.g., Schwartz v. Schwartz, 126 Nev. 87, 225
P.3d 1273 (2010).
90
See, e.g., Sogg v. Nevada State Bank, 108 Nev. 308, 832 P.2d 781 (1992) (marital agreement unenforceable
when financial disclosures not attached to document at time of signing).
