A prenuptial agreement checklist starts with full financial disclosure and then works through property, debt, spousal support, estate coordination, tax terms, retirement benefit waivers, and the signing formalities your state requires. Miss any one of these and a judge can set the agreement aside years later, so each item earns its place for a reason.
Financial Disclosure Packet
Transparency is the single biggest factor in whether a prenup survives a challenge. If either partner hides an account, understates a debt, or omits a business interest, a court can void the entire agreement. Both of you should assemble a complete disclosure packet before any drafting begins.
On the asset side, pull current statements for every bank account, brokerage account, and retirement plan. Collect deeds and titles for real estate and vehicles. Appraise jewelry, art, collectibles, or antiques worth real money so you have a defensible value rather than a guess.
Debts get the same treatment. List every outstanding balance: student loans, mortgages, car loans, personal loans, and credit cards, with the current balance, interest rate, and monthly payment for each. The agreement will later specify who stays responsible for which obligations, and it cannot do that cleanly without a full list.
For income, gather the last two to three years of federal tax returns and your most recent pay stubs. Freelance income, rental income, and side-business revenue should come with profit-and-loss statements or 1099s. The goal is a complete picture that lets both attorneys draft terms matching your real finances.
Property and Debt Provisions
The heart of the agreement decides what stays separate and what becomes shared. Without a prenup, your state’s defaults govern: community property states generally split marital assets equally, while equitable distribution states divide based on fairness. The prenup overrides those defaults within the limits your state allows.
Separate and Marital Property
Separate property typically includes anything you owned before the wedding plus inheritances and gifts received during the marriage. Identify these assets by name and account number so there is no ambiguity later. Address future earnings directly: will your salary stay separate, become marital property, or follow a hybrid rule? Vague language here is where most disputes start.
The family home deserves its own clause. Spell out who can live there during a separation, whether one spouse can buy out the other’s equity, and when the property must be sold.
Business Interests
If either partner owns a business, address both its current value and its future growth. Without specific language, appreciation in a pre-existing business during the marriage can be treated as a marital asset. The agreement can designate the business and all future increases in value as the sole property of the original owner. Reference a current business valuation or a recent buy-sell agreement so both sides know what is on the table.
Debt Allocation
Pre-marital debts can be assigned to whichever spouse incurred them. Debts taken on individually during the marriage, such as a credit card in one name, can be assigned the same way. For joint obligations like a shared mortgage, the agreement specifies how payments and remaining balances get divided if the marriage ends. Business-related debts warrant a separate provision so one spouse’s entrepreneurial risk does not become the other’s liability.
Spousal Support, Estate Terms, and Sunset Clauses
Alimony
You can waive spousal support entirely, cap it at a dollar amount, tie it to the length of the marriage, or use a formula that adjusts over time. Some couples link payments to milestones: a spouse who left a career to raise children might receive more than one who stayed in full-time work. Whatever you choose, the terms need to be specific enough for a court to enforce without guessing at your intent.
Death and Estate Coordination
A surviving spouse has statutory rights to a portion of the deceased spouse’s estate in most states, regardless of what a will says. The prenup can specify how assets are distributed at death, preserving inheritance plans for children from prior relationships or other beneficiaries. If you are updating wills or trusts alongside the prenup, make sure the documents do not contradict each other.
Sunset Clauses
A sunset clause sets an expiration date for the agreement or specific provisions within it. After a set number of years or a triggering event like the birth of a child, the agreement terminates or converts to the state’s default rules. Common timelines run from five to twenty years. Not every prenup needs one, but it is worth deciding whether a long marriage should still be governed by terms written before it started.
What a Prenup Cannot Include
Knowing the boundaries matters as much as knowing the contents. Provisions that cross these lines can also invite a judge to look more skeptically at the rest of the document.
Child Custody and Child Support
No prenup can dictate custody, parenting schedules, or child support. Courts decide those questions based on the child’s best interests at the time of separation. The Uniform Premarital Agreement Act, adopted in some form by roughly half the states, explicitly provides that a prenup cannot adversely affect a child’s right to support. Any clause attempting to predetermine custody or limit child support will be struck down.
Unconscionable or Illegal Terms
A grossly one-sided agreement can be declared unconscionable and thrown out. Courts evaluate fairness both at signing and at enforcement, so a provision that seemed reasonable years earlier can fail if circumstances changed dramatically. Terms that violate state law or public policy are also unenforceable.
Lifestyle Clauses
Financial penalties for weight gain, religious practice, social media use, or infidelity appear in draft prenups and are increasingly rejected by courts. In no-fault divorce states, which now include every state, judges are especially reluctant to enforce terms that punish marital conduct. Vague or punitive lifestyle clauses are likely unenforceable, and even clearly drafted ones often will not be upheld.
Tax Terms Worth Addressing
Asset Transfers Between Spouses
Transfers of property between spouses during the marriage are generally tax-free. Federal law treats them as gifts with no recognized gain or loss, and the receiving spouse takes over the transferor’s original cost basis.1Office of the Law Revision Counsel. 26 USC 1041 – Transfers of Property Between Spouses or Incident to Divorce The unlimited marital deduction means no gift tax applies either.2Office of the Law Revision Counsel. 26 US Code 2523 – Gift to Spouse If the prenup contemplates a large transfer, structuring it to occur after the wedding avoids gift tax exposure on a pre-marital transfer.
Basis Carryover in Divorce
Tax-free treatment extends to transfers incident to divorce, but basis carries over with the asset. If an appreciated asset moves to you, you inherit the original cost basis rather than current fair market value, and you will owe capital gains tax on all the appreciation when you eventually sell. A prenup that allocates specific assets should account for that built-in liability so the division is genuinely equitable rather than equal only on paper.
Filing Status
The agreement can address whether you will file jointly or separately during the marriage. Joint filing usually produces a lower combined tax bill but makes both spouses jointly liable for the entire return. If one spouse has complex business income, aggressive deductions, or existing tax debts, a separate-filing clause protects the other from shared liability. The prenup can also specify that even when filing jointly, each person’s separate assets remain legally distinct under the agreement’s property framework.
Retirement Benefits and the ERISA Gap
This is where prenups collide with federal law, and most couples do not see it coming. Under ERISA, the federal statute governing employer-sponsored retirement plans like 401(k)s and pensions, a spouse has an automatic right to survivor benefits. Waiving that right requires a written consent signed while the parties are already married, witnessed by a plan representative or notary, and designating an alternate beneficiary.3Office of the Law Revision Counsel. 29 USC 1055 – Requirement of Joint and Survivor Annuity and Preretirement Survivor Annuity
Because a prenup is signed before the marriage, it cannot satisfy ERISA’s requirement that the waiver come from a current spouse. A prenuptial waiver of 401(k) or pension survivor benefits is not enforceable against the plan. The workaround is to include the intent to waive in the prenup and then execute a separate postnuptial waiver after the wedding that meets ERISA’s procedural requirements. If retirement accounts are a significant piece of your financial picture, your attorney needs to flag this early and build the postnuptial step into your timeline.
IRAs are not governed by ERISA and follow state law, so a prenuptial waiver of IRA rights generally holds up. The distinction between ERISA-covered plans and IRAs matters enough that your disclosure packet should identify which type each retirement account falls under.
Making It Enforceable
Courts evaluate enforceability on several grounds, and failing any one of them can sink the agreement.
Full Financial Disclosure
The Uniform Premarital Agreement Act makes an agreement unenforceable if the challenging spouse was not provided fair and reasonable disclosure of the other party’s finances and did not voluntarily waive the right to that disclosure in writing. States that have not adopted the UPAA apply similar principles. The disclosure packet described above is the legal foundation the rest of the document rests on.
Independent Legal Representation
Each partner should have their own attorney. Shared counsel, or no counsel for one side, makes the agreement far more vulnerable. Independent lawyers tailor advice to each person’s interests and create a record that both sides understood what they signed. Total attorney fees typically run from $1,000 to $10,000 depending on complexity, with each side paying their own.
Voluntariness and Timing
The agreement must be signed voluntarily, without coercion. Courts look hard at timing. A prenup presented the day before the wedding, with deposits paid and guests arriving, is a textbook duress scenario, and a court seeing that timeline will likely set the agreement aside. Start the conversation months before the ceremony, give both sides time to review drafts with their own attorneys, and sign well in advance.
Substantive Fairness
Even a procedurally clean prenup can fall if its terms are unconscionable. Courts assess fairness both at signing and at enforcement. An agreement that leaves one spouse destitute while the other walks away with everything will not survive review. A prenup designed to be fair to both sides is more likely to hold.
Signing and Storing the Document
Execution
Both parties must sign in the presence of a notary public, who verifies identities and witnesses the signatures. Some states require additional witnesses beyond the notary. Check your state’s requirements before the signing appointment; a missing witness can create an enforceability problem years later.
Electronic Signatures
The federal E-SIGN Act and the Uniform Electronic Transactions Act give electronic signatures legal equivalence to handwritten ones in most commercial contexts. For prenups, the answer depends on your state. Some states exclude family law documents from their electronic transaction laws, which means a digitally signed prenup may not hold up. If your state does allow it, use software that provides an embedded digital certificate, timestamps, and tamper protection. When in doubt, sign in wet ink.
Storage
Keep the original signed document in a fireproof safe or bank safe deposit box. Each spouse should keep a copy, and each attorney should retain one. Scan the notarized document into encrypted cloud storage or a secure external drive as a backup. If the agreement is ever enforced, you do not want the outcome to hinge on whether anyone can find the original.
Changing the Agreement Later
A prenup is not permanent. Both modification and revocation are possible, but each requires the same formality as the original.
Amendment
To modify a prenup, both spouses must agree in writing. Verbal agreements do not count. The amendment should identify the specific provisions being changed, be reviewed by each spouse’s attorney, be signed by both parties, and be notarized. A sloppy amendment can undermine not just the changes but the original agreement.
Revocation
If both spouses agree to cancel the prenup, they can do so with a written rescission that is voluntarily signed and notarized. If only one spouse wants out, they will need to go to court. Judges may revoke an agreement when there is evidence of fraud, non-disclosure, failure to meet execution requirements, or changed circumstances that make enforcement severely unfair.
Postnuptial Agreements
When the changes you need go beyond a simple amendment, a postnuptial agreement can replace the prenup entirely. Postnups follow similar disclosure and fairness rules, and some states apply greater scrutiny because the parties are already married. A postnup is also the required vehicle for the ERISA-compliant retirement waiver that the prenup itself could not accomplish.
