Do Both Parties Need a Lawyer for a Prenup in Florida?

By Nadia Pazos, Family Law Attorney, Pazos Law Group · Updated September 2026

One of the most frequent questions couples ask when considering a prenuptial agreement is whether both people need their own attorney. The answer involves a distinction that matters enormously in practice: the difference between what the law requires for a prenup to be valid and what the law requires for a prenup to be enforceable.

This post explains what Florida's prenuptial agreement statute says about legal representation, why independent counsel matters for enforceability, and what happens when one or both parties sign without a lawyer.

What § 61.079 Requires

Florida's Uniform Premarital Agreement Act, Fla. Stat. § 61.079, sets out the requirements for a valid prenuptial agreement. Under § 61.079(3), the agreement must be in writing and signed by both parties. The statute does not include a requirement that either party be represented by an attorney.

This means that, as a matter of law, two people can draft, sign, and execute a prenuptial agreement without any attorney involvement, and the agreement will be technically valid. The marriage itself provides sufficient consideration, and no other formality — including legal representation — is required for the agreement to take effect upon the marriage.

But validity is only the first question. The far more important question is what happens when one spouse later asks a court to set the agreement aside.

Independent Counsel and Enforceability

The enforceability provisions of § 61.079(7) are where independent counsel becomes critically important. Under § 61.079(7)(a), a prenuptial agreement is unenforceable if the challenging party establishes that he or she did not sign the agreement voluntarily, or that the agreement was unconscionable when it was executed and certain conditions related to disclosure are met.

Section 61.079 does not mention independent counsel. Subsection (7)(a) lists the grounds a challenger must prove: involuntary execution; fraud, duress, coercion, or overreaching; or unconscionability combined with all three disclosure conditions in subsection (7)(a)3. Lack of counsel, by itself, is not one of those grounds.

Independent advice can reduce later disputes about what a signer understood, which rights were waived, and whether there was pressure to sign. But the absence of independent counsel, standing alone, does not establish any ground for nonenforcement under § 61.079(7)(a).

What "Independent Counsel" Means

Independent counsel means that each party has his or her own separate attorney — not the same attorney representing both parties, and not one party's attorney reviewing the agreement for the other party. Each attorney's duty runs exclusively to his or her own client.

This distinction matters because a single attorney cannot represent both parties in a prenuptial agreement negotiation. The interests of the two parties are inherently adverse. One party's gain in a prenup provision is the other party's concession. An attorney who attempts to represent both sides faces an irreconcilable conflict of interest.

Florida's Rules of Professional Conduct prohibit an attorney from representing a client if the representation involves a concurrent conflict of interest — that is, if the representation of one client will be directly adverse to another client. Drafting a prenuptial agreement for both parties falls squarely within this prohibition.

When we say each party should have "independent counsel," we mean a separate, independently retained attorney whose sole obligation is to advise and protect that client's interests in the prenuptial agreement process.

What Happens When Only One Party Has a Lawyer

A common scenario is one in which the wealthier or more financially sophisticated party retains an attorney to draft the prenup, and the other party signs the agreement without independent legal advice. This situation creates significant enforceability risk.

The unrepresented party can later argue that he or she did not understand the legal significance of the agreement's terms, was not informed of the rights being waived, felt pressured to sign because the other party had legal counsel and appeared to have the upper hand, or did not receive an adequate explanation of Florida's equitable distribution and alimony laws. Those allegations still must be proved under the statutory grounds. The absence of a lawyer does not create a separate claim, although the advice, information, and time available before signing may form part of the factual record.

Florida decisions evaluate the complete circumstances rather than apply an automatic counsel rule. Casto v. Casto, 508 So. 2d 330 (Fla. 1987), reaffirmed that legal counsel is not essential to a valid marital agreement. Independent advice remains useful because it helps a signer understand the proposed waivers and creates a clearer record of the process.

The Role of Independent Counsel in the Process

Having independent counsel does more than check a box for enforceability purposes. A family law attorney retained to review a prenuptial agreement serves several important functions for the client.

• Explaining rights. The attorney explains what rights the client would have under Florida law without a prenup — including equitable distribution under § 61.075, alimony under § 61.08, and homestead rights — so the client can make an informed decision about which rights to waive or modify.
• Reviewing financial disclosures. The attorney reviews the other party's financial disclosures for completeness and accuracy, ensuring that the client has a clear picture of what is at stake.
• Negotiating terms. The attorney can negotiate specific provisions on the client's behalf, pushing back on terms that are unfair or overly one-sided.
• Documenting the process. The attorney's involvement creates a record that the client received legal advice, understood the agreement, and signed voluntarily — all of which support enforceability.
• Identifying issues. An experienced family law attorney may identify issues that the client had not considered, such as the treatment of future business income, the impact of children on alimony, or the implications of Florida's homestead laws.

Can One Attorney Represent Both Parties?

Pazos Law Group represents one person in a prenup matter, not both. If Nadia drafts for one future spouse, the other person may retain separate counsel. If Nadia performs an independent review, she represents only the signer who hired the firm. This makes the attorney-client relationship clear throughout drafting and negotiation.

A written acknowledgment that someone had time and an opportunity to seek independent advice can document part of the signing process. It does not prove voluntariness, cure fraud or overreaching, or replace the disclosure analysis required by § 61.079(7)(a)3.

Practical Guidance: How to Handle Legal Representation

For couples considering a prenuptial agreement in Florida, the following approach provides the strongest foundation for enforceability.

1. Each party retains separate counsel. Both parties should have their own family law attorney. Ideally, both attorneys are experienced in Florida prenuptial agreement law.
2. Start early. The prenup process should begin well before the wedding — at least 30 to 60 days in advance, and ideally longer. A compressed timeline can suggest that one party was pressured to sign.
3. Exchange financial disclosures through counsel. Each party's attorney should review and exchange financial disclosures, ensuring completeness and accuracy.
4. Negotiate through counsel. Terms should be negotiated between the attorneys, with each party providing instructions to his or her own lawyer. This creates a clear record of arm's-length negotiation.
5. Sign with counsel present. Both parties should sign the agreement with their respective attorneys present. Some practitioners recommend having each attorney sign an acknowledgment that his or her client received independent legal advice.

What If One Party Refuses to Get a Lawyer?

Sometimes one party declines to retain an attorney, whether due to cost, indifference, or a belief that legal representation is unnecessary. In this situation, the party who has counsel should take steps to protect the agreement's enforceability. This includes ensuring that the unrepresented party is given a written recommendation to seek independent counsel, providing ample time for the unrepresented party to review the agreement and consult with an attorney if desired, and ensuring that the financial disclosures are particularly thorough and transparent.

These steps do not eliminate the enforceability risk, but they reduce it. The goal is to create a record showing that the unrepresented party had every opportunity to obtain legal advice and made an informed choice not to do so.
