Can Parents Require a Child’s Prenup in Florida?

1. Parents Are Not Parties to the Prenup

Parents often ask me, “Can we sign our son’s prenup so the family is protected too?” The answer is no. Florida defines a premarital agreement as an agreement between prospective spouses, made in contemplation of marriage and effective when they marry. The two people getting married sign it, the two of them are bound by it, and either of them can later ask a court to enforce it or set it aside. Parents are outside all of that.

Standing outside the agreement has practical consequences for a parent.

• Parents cannot sign it or be bound by it. A promise by the parents inside the prenup, such as a promise to give the couple a house, is not an enforceable part of the couple’s agreement.
• Parents cannot enforce it. If the marriage ends and your child chooses not to rely on the agreement, you have no right to step in.
• Parents cannot change it later. After the wedding the agreement changes only by a writing signed by both spouses.

Parents can still describe what they have given or will leave, and the agreement can say it stays the child’s separate property. Florida already treats gifts and inheritances from parents as separate in a divorce, so the prenup’s real work is keeping that protection when the money is used in the marriage, and protecting it at death. See whether an inheritance is marital property.

2. When Parental Pressure Puts the Prenup at Risk

Florida will not enforce a prenup against a spouse who proves the agreement was not signed voluntarily, or that it was the product of fraud, duress, coercion or overreaching. The person who can raise those grounds is the fiancé, years later, in a divorce. Pressure from parents matters because it usually arrives at the fiancé through the child, close to the wedding.

Florida courts draw the line in a fairly consistent place.

1. Asking is lawful. Insisting on a prenup, and saying plainly that there will be no wedding without one, is not duress by itself.
2. Timing and terms change the answer. An agreement presented days or hours before the ceremony, with terms heavily favoring one side and no real chance for the fiancé to get advice, is the pattern courts set aside. The case at the bottom of this page started with a father’s advice and ended with the agreement thrown out.
3. Pressure on your own child matters too. A child who signs a lopsided agreement only because a parent insisted, or who negotiates nothing because a parent is directing the terms, makes the whole process look like something other than two people bargaining for themselves.

A parent who wants the agreement to hold should want the fiancé to have time, a separate lawyer and terms a court will see as reasonable. See what makes a prenup invalid.

3. Whose Lawyer Is It? Representing the Child

When parents call about a child’s prenup, the first question to answer is who the client is. On the agreement itself, the lawyer’s client is the child getting married, and the parents and the child should not share one lawyer on it, because their interests often conflict. Parents usually want the strongest possible terms, and the child has to live in the marriage the terms create.

Florida’s ethics rules shape the arrangement in three ways.

• Conflicts. A lawyer cannot represent one client where the representation is directly adverse to another client, or where duties to someone else would materially limit the advice, without informed consent and only where the lawyer can still serve each client competently. On a prenup the safer course, and mine, is to represent the child alone.
• Who pays. Parents may pay the fee if the child gives informed consent, the parents do not interfere with the lawyer’s judgment or the relationship with the child, and the child’s confidences are protected. A person who pays a lawyer to serve someone else cannot direct or regulate the lawyer’s judgment.
• What parents hear. Parents learn what the child agrees they can learn. A child who wants to share the draft with a parent can, and a child who does not want to is entitled to that.

Parents who want advice about their own planning have their own engagement, which is the subject of the next section. The parents’ interests in that work are their own, and those interests line up with the child’s far more often than in a prenup negotiation.

4. The Better Tool Is Often the Parents’ Own Estate Plan

Parents control their own money completely, and a trust is how they decide the terms on which a child receives it. The future spouse is not a party to the parents’ trust, does not sign it, and in most families never reads it.

A lifetime trust for the child does three things a prenup cannot.

1. The trust protects the money in a divorce. The trustee owns the assets. Where distributions are up to the trustee’s discretion, Florida law says no creditor can force a distribution, including a spouse or former spouse with a support order. The child’s spouse reaches money only after the trustee pays it out and the child mixes it with marital funds.
2. The trust protects the money at the child’s death. The share passes as the parents’ trust directs, usually to the grandchildren, and never becomes part of the child’s estate. The child’s surviving spouse has no 30 percent elective share in it.
3. The trust works whether or not the child ever signs a prenup. A child can marry, remarry or decline to ask for a prenup, and the trust keeps working.

The design choices decide how strong the protection is. An independent trustee, or the child as co-trustee with an independent co-trustee, protects more than the child acting alone, because a beneficiary who is sole trustee with power to pay himself can lose part of the protection. The child can still have real use of the money, including living in a house the trust owns.

I draft these trusts. In our fee schedule it is the Protected Trust Plan, in which each child’s share stays in trust for that child’s life. See protecting a child’s inheritance and Florida spendthrift trusts for how the protection works and where its limits are.

Gifts during the parents’ lifetime follow the same logic. A down payment given outright and used for a home titled in both names becomes, in practice, a gift to the couple. The same money held in a trust for the child, or lent with a signed note, stays on the family’s side.

5. If the Family Still Wants a Prenup

A trust and a prenup work well together, and some families want both. A prenup can still be the right tool, especially where the child already owns a business or real estate, or where the child expects to earn far more than the fiancé. I would want a parent to understand five steps.

1. Start early. Raise the subject months before the wedding, and get the draft to the fiancé weeks before it. A Florida appeals court has held ten days enough, and nobody should aim for the minimum.
2. The fiancé has a separate lawyer. Florida does not require it, and an agreement the fiancé negotiated with a lawyer is far harder to attack. Some families offer to pay for that lawyer, which is allowed if the lawyer takes no direction from the family.
3. Full disclosure. The child lists what the child owns, including any trust interest. A family that wants confidentiality can disclose fair values without disclosing every family document.
4. Reasonable terms. An agreement that leaves the fiancé with something real, such as a payment that grows with the length of the marriage, survives better than one that leaves nothing.
5. The parents step back. The child and the child’s lawyer negotiate. Parents who sit in on the negotiation or send terms to the fiancé create the record a challenge is built on.

What It Costs

For parents, the Protected Trust Plan holds each child’s share in a lifetime trust and is a flat fee from $4,700 for an individual. One fee covers every child. The trust plan without lifetime trusts is a flat fee from $3,200.

For the child, a prenup drafted for one spouse is a flat fee from $2,450, and a review of an agreement the other side drafted is a flat fee from $750. What each prenup fee includes is set out on the prenup page. Posted fees are honored for at least 90 days from September 2026. Government costs such as recording and filing fees are additional and passed through at cost.

Frequently Asked Questions

Common Situations

The family business. Parents own a distribution company and plan to leave a third of it to each of three children. One child is engaged. The parents’ trust holds each child’s shares for life, and the company’s shareholder agreement limits transfers to anyone outside the family. The engaged child’s prenup, negotiated by the child with the child’s own lawyer, confirms the shares stay separate.

The wedding in six weeks. A father learns his daughter has not discussed a prenup and wants one signed before the wedding. A rushed agreement now carries more risk than it removes. The father updates his own trust so his daughter’s inheritance stays in a lifetime trust, and the daughter and her husband consider a postnup after the wedding with time to do it properly.

The parents paying for the lawyer. Parents offer to pay for their son’s prenup. The son signs an engagement letter consenting to the arrangement, the lawyer represents only the son, and the son decides what the parents see. The fiancée has her own lawyer, whose fee the parents also offered to cover with no say in her advice.

The Father’s Advice and the Jeweler’s Counter

Most articles on this topic cite each other. I would rather cite the court, and the Florida case I would put in front of any parent thinking about a child’s prenup was decided in 1976.

A wealthy man in Chicago, divorced once, had been engaged for about four weeks. The man wanted a prenup, and he later told the court why. His father had advised it, and his first divorce had been hard. The couple had talked about an agreement on and off for about a year, but nothing was drafted until the Monday of the week they married.

On that Monday evening the groom proposed they marry just after midnight on Thursday, if he could book a honeymoon cruise to Europe leaving New York that day. The groom got the tickets. The couple spent Tuesday buying a sable stole and a wedding outfit, getting blood tests and passports, booking a judge and a private room at O’Hare, and inviting family and friends. On Thursday afternoon, while the jeweler sized their rings, he took the agreement out of his pocket and showed it to her for the first time. The bride objected. The groom called his own lawyers, put her on the phone, and told her that without a signature there would be no wedding. The bride signed at the airport around 12:30 in the morning, with his nephew acting as notary.

The agreement limited her to $1,000 a month if they ever separated, and each would pay their own lawyers. The groom was worth at least $3 million. Ten years later they divorced, and in 1976 a Florida appeals court let her avoid the agreement. The court said fairness would include “an opportunity to seek independent advice and a reasonable time to reflect on the proposed terms.”

I have a few take-home points.

The first is that the father’s advice was sound. A prenup made sense for a man with $3 million and a hard first divorce. The husband lost the agreement in the execution, by leaving a year of good intentions undrafted until the week of the wedding. Many cases like this keep coming up with the same calendar, a prenup discussed for months and drafted in the last few days.

The second is that his own lawyers were on the phone, and it did not help. The bride spoke to the drafter’s lawyers, the document did not change by a word, and the court said whatever advice she got that afternoon did little to offset the rest.

Practice pointer. A parent who wants a child to have a prenup should push for the calendar, not the terms. A draft in the fiancé’s hands with weeks to spare and a lawyer of the fiancé’s own choosing is worth more than any clause.

Avoid treating a prenup as the family’s only protection. A lifetime trust in the parents’ own plan needs no one’s signature at the jeweler’s counter.

An honest limit belongs here. The case was decided under the law before Florida adopted its premarital agreement statute in 2007, and a prenup signed today is judged under that statute. In the Florida case law I have reviewed, no appellate decision applies the statute’s voluntariness test to a prenup signed after 2007, so the old cases remain the clearest guide to how a court would weigh these facts.
