Preparation of postnuptial agreements for married couples addressing property, business interests and financial arrangements.
A financial conversation that happens after the wedding instead of before
Couples arrive at a postnuptial agreement for many reasons: they married without a prenuptial agreement, their financial circumstances changed significantly, or they simply want to formalize an understanding they had discussed informally. Section 732.702 of the Florida Statutes and the general framework governing marital contracts allow married couples to enter into these agreements, subject to standards similar to those applied to premarital agreements.
Common reasons couples pursue a postnuptial agreement
- One spouse starts, acquires, or receives an ownership interest in a business during the marriage.
- A significant inheritance or gift is received by one spouse.
- The couple wants to clarify how existing or future assets will be treated going forward.
- One spouse is taking on a financial risk (a new venture, a guaranty, a career change) that the couple wants to address contractually.
- The couple wants to update or replace terms from an earlier prenuptial agreement.
Disclosure, independent counsel and voluntariness still matter
The same principles that support an enforceable prenuptial agreement apply to a postnuptial agreement: full financial disclosure by both spouses, independent counsel for each side and a process free of pressure or coercion. Because the agreement is being negotiated within an existing marriage, courts scrutinize fairness and voluntariness closely, making a careful, well-documented process especially important.
Addressing a business interest that developed during the marriage
When a spouse's business grows or is founded after the wedding, a postnuptial agreement can specify how that interest and its future value will be treated, reducing ambiguity for both spouses and, where relevant, for co-owners or investors in the business who want clarity about ownership.
Answers
Frequently asked questions
- Is a postnuptial agreement as enforceable as a prenuptial agreement?
- Both types of agreements can be enforceable under Florida law, but postnuptial agreements are often reviewed with particular attention to fairness and voluntariness because the couple is already married when it is signed, making careful process and disclosure especially important.
- Can we sign a postnuptial agreement if we didn't have a prenup?
- Yes. Many couples who married without a prenuptial agreement later choose to formalize their financial arrangement through a postnuptial agreement, often prompted by a change in circumstances.
- What if my spouse and I disagree about the terms?
- Negotiation between separately represented spouses is a normal part of reaching a postnuptial agreement both parties are comfortable signing. The firm's role is to support that negotiation and ensure the resulting document is clear and properly documented.
- Can a postnuptial agreement address what happens to our estate plan?
- It can and should be coordinated with existing or planned estate planning documents, since inconsistencies between a postnuptial agreement and a will or trust can create confusion or disputes later.
- Can the agreement be updated again later in the marriage?
- Yes, spouses can revisit and amend a postnuptial agreement as circumstances change, following the same standards of disclosure and voluntary, informed consent.
