Common questions
Frequently Asked
4
Does a nuptial agreement require consideration to be enforceable?+
No. Under governing marital property statutes, a written agreement signed by both spouses reallocating property rights is enforceable without any bargained-for exchange or monetary payment.

Can spouses use a postnuptial agreement to reclassify stock options granted during marriage?+
Yes. A written marital agreement expressly designating stock options as one spouse's individual property overcomes the presumption that assets acquired during marriage are marital property.
Supporting sources
May an arbitrator issue an annulment under a broad nuptial arbitration clause?+
No. Even when a postnuptial agreement authorizes an arbitrator to grant any relief a family court could order, the arbitrator lacks authority to alter marital status through annulment or divorce.
