Prenuptial Planning: Agreements and Premarital Trusts
Prenuptial planning is the set of documents that decide, before a marriage, what happens to each spouse’s property if the marriage ends by divorce or by death. For most of our clients the concern is not the divorce; it is a family business, real estate accumulated before the marriage, an expected inheritance, children from a prior relationship, or an estate plan that would be affected by a spouse’s statutory rights. A prenuptial agreement addresses those questions directly. A premarital trust addresses some of them structurally, by placing assets beyond either spouse’s reach before the wedding. The two are often used together.
The agreement is only as good as its enforceability, and each of our states has rules about disclosure, counsel, timing, and fairness that decide whether a court will honor it years later. We draft agreements with those requirements in mind, and we advise clients when a term they want is one a court is unlikely to enforce.
Milvidskiy Law Group P.C. drafts and negotiates prenuptial and postnuptial agreements, designs premarital trusts, and integrates both with the wills, trusts, and business agreements they are meant to protect. We represent one party only; the other party should be represented by independent counsel.
Key Takeaways:
- A prenuptial agreement can define separate and marital property, waive or limit spousal support and the surviving spouse’s right to a share of the other’s estate, and address a business or an inheritance. It cannot decide child custody or child support.
- Enforceability depends on formalities and fairness: a written, signed agreement, acknowledged in the manner each state requires; full financial disclosure or a knowing written waiver; a genuine opportunity for independent counsel; and terms that are not unconscionable. New York, New Jersey, and Connecticut each state these rules differently.
- A premarital trust does not depend on the agreement’s enforcement, because assets properly transferred to the trust are no longer the spouse’s to divide. It is often the better tool when the goal is to keep a family business, real estate, or an inheritance in the family regardless of what happens to the marriage.
What a Prenuptial Agreement Does
- Defines property. Which assets are separate, whether appreciation and income on separate assets remain separate, how commingled assets are treated, and what is marital.
- Addresses support. Whether spousal support will be paid on divorce, how much, and for how long, within the limits each state imposes.
- Addresses death. Each state gives a surviving spouse a right to a share of the deceased spouse’s estate regardless of the will. A prenuptial agreement can waive that right, in whole or in part, and can instead provide for the survivor through life insurance, a trust, or a specific bequest. This provision makes a prenuptial agreement an estate planning document and is essential to estate planning for blended families when the estate is meant to pass to children of a first marriage.
- Addresses a business. Keeps ownership of a family or professional business with the founding spouse, coordinates with the operating or shareholder agreement’s transfer restrictions, and defines how a spouse’s contributions to the business are compensated. These terms should align with business succession planning.
- Addresses an inheritance or a trust. Confirms that inherited assets and interests in family trusts remain separate, including their growth.
A prenuptial agreement cannot fix child custody or child support, which courts decide on the children’s interests at the time, and it cannot waive rights the law does not allow to be waived.
What Each State Requires
New York
An agreement made before or during the marriage is valid and enforceable in a matrimonial action if it is in writing, signed by the parties, and acknowledged or proven in the manner required to entitle a deed to be recorded. The agreement may address testamentary provisions and wills, ownership and division of separate and marital property, maintenance, and other matters, provided the maintenance terms were fair and reasonable when the agreement was made and are not unconscionable when a final judgment is entered.
The acknowledgment requirement is strict, and agreements have been set aside for a defective acknowledgment alone.
New Jersey
Under New Jersey’s premarital agreement act, the party seeking to set aside an agreement bears the burden of proving by clear and convincing evidence that it is unenforceable. An agreement is not enforceable if, before signing, the party was not provided full and fair disclosure of the other party’s earnings, property, and financial obligations and did not waive disclosure in writing; did not have, and could not reasonably have had, adequate knowledge of the other party’s finances; or did not consult independent legal counsel and did not waive that opportunity in writing.
Unconscionability is decided by the court as a matter of law, and for agreements signed or amended after mid-2013 the analysis focuses on the circumstances at signing. In practice that means disclosure schedules, separate lawyers, and time.
Connecticut
Under Connecticut’s premarital agreement act, the agreement must be in writing and signed by both parties, and it is enforceable without consideration. It is not enforceable if the party resisting it proves that the party did not sign voluntarily, that the agreement was unconscionable when signed or when enforcement is sought, that the party was not given fair and reasonable disclosure of the other’s property, obligations, and income, or that the party was not afforded a reasonable opportunity to consult independent counsel.
If a support waiver would leave a spouse eligible for public assistance at separation or dissolution, the court may order support notwithstanding the agreement.
Premarital Trusts
A prenuptial agreement is a contract, and a contract can be challenged. A premarital trust changes the ownership of the assets instead. Before the wedding, a client places a business interest, real estate, or investment assets in an irrevocable trust. Once the assets belong to the trust, they are generally no longer the client’s property to divide or to leave, and a spouse’s statutory rights generally do not reach them. The trust can be a domestic asset protection trust in Wyoming or Nevada, or under Connecticut’s own statute, in which the client remains a discretionary beneficiary; a trust for the client’s children from a prior marriage; or a dynasty trust that continues for generations. Parents who intend to leave an inheritance to a child about to marry often make the gift to a trust for the child rather than outright, for the same reason.
The trust and the agreement work together. The agreement acknowledges the trust and confirms that trust assets and distributions are separate property; the trust removes the largest assets from the dispute. Timing matters: a trust funded years before the marriage is on stronger ground than one funded the week before, both under fraudulent transfer principles and in a court’s view of intent. The choice of trust should reflect the client’s broader asset protection needs.
Process and Timing
- Start early. An agreement presented days before a wedding invites a claim of duress. Allow several months for preparation and review.
- Disclose fully. Each party prepares a schedule of assets, liabilities, and income, attached to the agreement. Where a party waives further disclosure, the waiver is in writing.
- Separate counsel. Each party has his or her own attorney. We represent one party only.
- Negotiate the terms. Support, property, death provisions, and the treatment of a business or inheritance are discussed, not dictated.
- Sign correctly. With the acknowledgment or witnessing each state requires, and with the process documented.
- Coordinate the rest of the plan. Wills, trusts, beneficiary designations, and business agreements are updated so that they match the agreement, with marital deduction planning considered where appropriate.
Postnuptial Agreements
Couples who married without an agreement, or whose circumstances have changed, can sign a postnuptial agreement. The same formalities apply, and courts examine postnuptial agreements at least as closely because the parties are already married and the leverage differs. Postnuptial agreements are common after a business is founded during the marriage, after an inheritance, when one spouse creates a spousal asset protection trust that the other must acknowledge, and as part of reconciliation.
When Prenuptial Planning Is Not the Right Focus
A couple with comparable assets, no children from prior relationships, no business, and no expected inheritance may not need an agreement, and a poorly negotiated one can do more harm to the marriage than good to the estate. A client whose goal is to leave a future spouse with nothing should understand that courts do not enforce unconscionable terms and that a waiver of support may be overridden. A client who is already facing a claim or a pending divorce cannot use a trust to move assets out of reach; transfers made at that stage may be set aside as fraudulent transfers.

Frequently Asked Questions
What can a prenuptial agreement cover?
Which property is separate and which is marital, including appreciation and income on separate assets; whether and how much spousal support will be paid on divorce; each spouse’s rights in the other’s estate at death, including a waiver of the statutory share; and the treatment of a business, an inheritance, or a family trust. It cannot decide child custody or child support.
What makes a prenuptial agreement enforceable in New York?
Under New York law the agreement must be in writing, signed by the parties, and acknowledged in the manner required to record a deed. Maintenance terms must have been fair and reasonable when made and not unconscionable when a final judgment is entered. Agreements have been set aside for defective acknowledgments alone, so the signing formalities are handled with care.
What makes a prenuptial agreement enforceable in New Jersey?
The party challenging the agreement must prove by clear and convincing evidence that it is unenforceable. An agreement fails if, before signing, the challenging party did not receive full and fair disclosure of the other’s finances and did not waive disclosure in writing, lacked adequate knowledge of those finances, or did not consult independent counsel and did not waive that opportunity in writing. Unconscionability is decided by the court as a matter of law.
What makes a prenuptial agreement enforceable in Connecticut?
The agreement must be in writing and signed by both parties. It is unenforceable if the challenging party proves it was not signed voluntarily, that it was unconscionable when signed or when enforcement is sought, that fair and reasonable financial disclosure was not provided, or that the party was not afforded a reasonable opportunity to consult independent counsel. A support waiver that would leave a spouse on public assistance can be overridden.
Can a prenuptial agreement waive my spouse's inheritance rights?
Yes. Each state gives a surviving spouse a right to a share of the other’s estate regardless of the will, and that right can be waived in a properly executed agreement. The waiver is what allows a second-marriage estate plan to leave the estate to children of the first marriage, usually with the surviving spouse provided for through life insurance, a trust, or a specific bequest.
What is a premarital trust?
An irrevocable trust funded before the marriage with a business interest, real estate, or investments, so that those assets belong to the trust rather than to the spouse and are outside the marital estate and the other spouse’s statutory rights. It can be a domestic asset protection trust in which the client remains a discretionary beneficiary, a trust for children from a prior marriage, or a dynasty trust. It is often paired with a prenuptial agreement that acknowledges it.
How far before the wedding should we sign?
Allow several months where possible. An agreement presented shortly before the wedding invites a claim that it was signed under pressure, and a trust funded on the eve of the marriage is on weaker ground than one funded earlier. Starting early also leaves time for disclosure, negotiation, and each party’s counsel to do their work.
Do we each need a lawyer?
Yes. New Jersey and Connecticut make the opportunity to consult independent counsel an element of enforceability, and New York courts weigh it heavily. We represent one party only and will not advise both. The other party’s attorney reviews and negotiates on that party’s behalf.
Can we sign an agreement after we are married?
Yes. A postnuptial agreement follows the same formalities and is examined at least as closely by courts. Couples use them after a business is founded during the marriage, after an inheritance, when one spouse creates a trust the other must acknowledge, and as part of reconciliation.
Can a prenuptial agreement protect my business?
Yes. The agreement can confirm that the business and its growth are separate property, define how a spouse’s contributions to the business are compensated, and coordinate with the transfer restrictions in the operating or shareholder agreement so that a divorce does not put an interest in the hands of a former spouse. A premarital trust holding the business interest adds structural protection.
