If you already have a prenup draft in hand, whether written by yourself, copied off of a friend’s prenup, or even ChatGPT, the next step is a prenup review by your own independent attorney before you sign. A legal review by a licensed lawyer protects your interests by ensuring the agreement is enforceable, there are no harmful terms, and that you understood your rights.
Whether your partner’s lawyer drafted it, you used an online template, or the two of you wrote it together using AI. Either way, a prenup draft is not the finish line. This guide explains what a prenuptial agreement review covers, how the process works, and what it typically costs.
What is a prenup review?
A prenup review is when a lawyer who represents only you reads an existing prenuptial agreement draft, explains what it means, and advises whether you should sign, negotiate, or walk away from specific terms. The lawyer does not write the agreement from scratch. They evaluate the one already on the table.
A good prenup review by a lawyer answers three questions:
- What am I actually agreeing to? A plain-language explanation of every clause, including what happens upon certain triggers, such as divorce or death of one spouse.
- Is it fair to both parties? How the terms compare to what each party would likely receive under the state’s default rules without a prenup.
- Will it hold up? Whether anything in the draft or the signing process could make it unenforceable later.
Review is different from drafting. If you hire a lawyer to review, expect them to suggest redlines (i.e., tracked changes on the prenup) and negotiate with the other side’s attorney, but not to rebuild the document unless it is extremely flawed.
Why you need your own lawyer, not your partner’s
One lawyer cannot ethically represent both spouses in a prenup, because your interests are opposed on the exact issues the agreement covers. If your fiancé’s attorney drafted the agreement, that attorney works for your fiancé, even if they are friendly and walk you through it.
Independent review also matters for enforceability. When a prenup is challenged in divorce, courts commonly look at whether:
- Each person had a real chance to consult their own attorney.
- Each person signed voluntarily, without pressure or duress.
- Both sides gave full and fair disclosure of their assets, debts, and income.
- The terms were not unconscionable (grossly one-sided) when signed, and in some states when enforced.
A spouse who had no independent counsel has an easier argument that they did not understand what they signed. Some states go further. California, for example, generally requires at least seven days between when a party is first presented the final agreement and when they sign it, and imposes extra requirements on spousal support waivers when a party had no lawyer. (Cal. Fam. Code § 1615(c)).
In short, a review protects you, and it also protects the agreement itself. Many drafting attorneys actively encourage the other party to get a review for this reason.
What a prenup review covers
A thorough prenuptial agreement review goes clause by clause. These are the areas most lawyers focus on.
| Area | What the reviewer checks |
| Separate vs. marital/community property | How each asset is defined, and whether growth on separate assets (like a business or retirement account) stays separate |
| Commingling rules | What happens when separate money is mixed with joint money, such as a down payment on a shared home |
| The marital home | Who owns it, who gets credit for contributions, and who keeps it after divorce |
| Spousal support (alimony) | Whether support is waived, capped, or set by formula, and whether that is allowed in your state |
| Debts | Who is responsible for student loans, business debt, and debt taken on during the marriage |
| Death and estate rights | Waivers of inheritance, elective share, or retirement survivor benefits |
| Financial disclosure | Whether schedules of assets, debts, and income are complete and attached |
| Other miscellaneous clauses | Some prenups include embryo disposition, life insurance requirements, pet custody, etc. |
| General clauses | Choice of law, mediation or arbitration requirements, and who pays legal fees are common generic clauses you’ll see in most prenups. |
The reviewer should also ask about your life plans. A clause that looks fine today can be harsh if you later leave work to raise children or relocate for your spouse’s career.
How the prenup review process works
Most reviews follow the same basic path, from first call to signing. Prenup review may look different depending on how far along you are in the process, your attorney’s style, and the amount of time you have before the wedding. Here’s a general idea of how the prenup review process works:
- Initial consultation: You share your goals, your timeline, and the wedding date. Many attorneys offer a short free or low-cost first call.
- Send the draft and financial disclosures: Provide the full draft, both parties’ financial schedules, and any related documents such as trusts or business agreements.
- Attorney review: The lawyer reads the agreement. They may send you some follow-up questions via email.
- Review meeting: Your attorney walks you through each section, explains risks, and recommends changes.
- Redlines and negotiation: Your attorney sends proposed changes to your partner’s attorney. This can take one round or several to come to agreeable terms.
- Final version and signing: Once both sides agree on all of the terms/redlines, you both sign, usually with notarization (and sometimes even witnesses, depending on your state law).
Remember to start this process early. Aim to begin the review at least two to three months before the wedding so negotiation never feels rushed and no one can later claim they signed under pressure.
How much does a prenup review cost?
In the U.S., a prenup review often costs roughly $800 to $5,000+, depending on your location’s cost of living and how complex your finances and agreement are. Reviewing an existing draft usually costs less than having one drafted from scratch because the attorney doesn’t have to spend many hours drafting contract language.
Here are some variables that drive the pricing of a prenup review:
- Lawyer fee structure: Some prenup lawyers offer a flat fee for review. Others bill hourly, commonly a few hundred dollars per hour or more.
- Complexity of finances: Closely held businesses, trusts, vested/unvested stock compensation, real estate, and assets in multiple countries add complexity, which adds time.
- Amount of requests: If the prenup reviewer receives tons of requested edits from their client, those will take more time than if the client only asks for one change.
- Negotiation rounds: A flat fee may cover only the review meeting, with redlines and back-and-forth billed separately. Ask up front.
- Location: Rates in major metro areas are typically higher. For example, a Manhattan prenup review is generally going to be much higher than a rural Oklahoma prenup review.
Timing is usually one to three weeks for the initial review, plus however long negotiation takes. Weigh the fee against the stakes: a prenup can decide how assets, income, and support are divided for decades.
How to prepare and choose a reviewing attorney
The right lawyer and a little preparation make the review faster, cheaper, and more useful. Pick a family law attorney licensed in the state where you live or plan to live during marriage, not a general practitioner who isn’t familiar with prenuptial agreements. Sure, your family friend who does real estate law may seem enticing, but they likely don’t know the ins and outs of what makes a prenup hold up.
If assets cross borders, look for someone in those countries with family law experience. You may want to cross-reference the prenup with an American prenup lawyer and also a family law lawyer in that country.
What to bring to your prenup review session:
- The complete draft, including all schedules and exhibits
- Your partner’s financial disclosure and your own
- A short list of your goals and the clauses that worry you
Write down your questions before the meeting. Common ones include what you would get without a prenup, what happens if you have children, and what happens if one of you dies.
Do I legally need a lawyer to review my prenup?
Typically, no; in many places, it is not strictly required, but it is strongly recommended. There are a few exceptions to that. Here are places where you legally need a lawyer to review your prenup:
- South Carolina (Proposed § 20-1-110(A)(1)–(2))
- West Virginia (Ware v. Ware, 224 W. Va. 599, 687 S.E.2d 382 (2009))
- Alabama, but only if the agreement cannot satisfy the alternative test of adequate consideration and fairness. (Barnhill v. Barnhill, 386 So. 2d 749, 751 (Ala. Civ. App. 1980)).
- California, but only if you waive or limit spousal support (Cal. Fam. Code § 1612(c))
- New York, but only if you are disposing of your embryos within the agreement (NY Fam. Court Act § 581-306(a)(2)(d)).
- Washington, but only if the agreement is substantively unfair, and even then, whether independent counsel is required depends on the circumstances. (In re Estate of Crawford, 730 P.2d 675 (1986)).
In every other state, it is not required to have a lawyer review your prenup. Even in those states where prenup review by a lawyer is not required, at least having the opportunity to have a lawyer review it is critical. In other words, neither party can be forced into signing without having the chance to get a lawyer if they want one.
Can my partner’s lawyer review it for me?
No, your partner’s lawyer cannot review it for you. Your partner’s lawyer represents your partner. You need an attorney whose only duty is to you. It is unethical and a conflict of interest for your partner’s lawyer to offer to review your agreement for you as well. This is because your interests may differ, and advice that protects your partner could come at your expense. Your own attorney can explain the rights you’re giving up, flag potential risks, and advocate for terms that protect you.
Furthermore, many states have codified ethics rules prohibiting lawyers from advising someone whose interests conflict with their client’s. For example, New York Rule of Professional Conduct 4.3 (22 NYCRR Part 1200) and California Rule of Professional Conduct 4.3(a) prohibit a lawyer from giving legal advice to an unrepresented person in these circumstances, other than recommending that they obtain counsel.
In other words, your partner’s lawyer may explain the proposed agreement, but that is different from reviewing it to protect your interests.
Frequently Asked Questions (FAQs)
Can I get a prenup reviewed online?
Yes. Many family law attorneys offer remote review by video call, as long as they are licensed in the relevant state.
How long before the wedding should I get my prenup reviewed?
Ideally two to three months, but prenup reviews are more frequently done much closer to the wedding. Some lawyers will offer prenup review as soon as one day before the wedding. This also depends on the state law and what it will allow.
What if I want changes and my partner refuses?
Your attorney can help you understand which points matter most and where compromise is reasonable. If you cannot agree, you can choose not to sign.
Can a prenup be changed after the wedding?
It depends on your state law. In most states, yes, through a postnuptial agreement or a written amendment signed by both spouses, usually with the same formalities as the original.
The bottom line: get your prenup draft reviewed before you sign
Having a prenup draft is a great start, but signing without an independent review is one of the most common and costly mistakes couples make. A review helps you understand every clause, negotiate terms that fit your future, and sign an agreement that is much more likely to be enforced.
If you already have a draft, contact a family law attorney in your state now, ideally months before the wedding, and ask for a prenup review consultation.
