Key takeaways
Prenuptial agreement attorney fees are almost always a flat fee — commonly $1,000–$2,500 to draft a straightforward prenup, and often $3,000–$7,500 or more when there are significant assets, a business, or heavy negotiation. For a prenup to hold up, each spouse generally needs their own independent attorney, so most couples pay two fees, with the reviewing attorney usually charging less than the drafting one. Because a prenup is not filed with a court, there are no court costs — the fee is purely for legal work. A well-drafted prenup is far cheaper than the divorce litigation it can prevent, and its enforceability turns on full financial disclosure, voluntary signing, and your state’s law.

Average fees for prenuptial agreement lawyers in the US
A prenuptial agreement lawyer fee is what an attorney charges to draft or review a prenup — a contract setting how assets, debts, and support are handled if the marriage ends — usually a flat fee of about $1,000–$2,500, rising for complex estates or heavily negotiated agreements.
The figures below span a simple, flat-fee prenup through a complex, negotiated one. What you pay depends mostly on the complexity of your finances and how much the agreement is negotiated, and prenup enforceability is governed by state law, so enter your ZIP for localized context. Most attorneys quote a flat fee, with hourly billing reserved for high-asset or heavily contested agreements.
For a prenup to be enforceable, each spouse generally needs their own independent attorney, so most couples pay two fees — the drafting attorney’s and the reviewing attorney’s (usually lower). Highly negotiated or high-asset agreements may be billed hourly ($250–$400) instead of a flat fee.
Factors affecting the fee
Several factors influence the fee you are quoted and the final amount you take home:
- Complexity of assets. A business, real estate, or investments require more drafting and disclosure.
- Drafting vs. reviewing. Drafting the agreement costs more than reviewing one the other side prepared.
- Degree of negotiation. Back-and-forth between the two attorneys adds hours and cost.
- Support & sunset terms. Spousal-support waivers and sunset clauses add complexity to enforce.
- Attorney experience. Experienced family-law attorneys command higher flat or hourly fees.
- Jurisdiction. State enforceability rules and disclosure requirements vary.

How prenup attorneys charge: flat fees and what raises them
Drafting a prenuptial agreement is almost always quoted as a flat fee, so you know the cost up front — commonly $1,000–$2,500 for a straightforward agreement. The fee rises with the complexity of your finances (a business, real estate, investments, or significant separate property) and with how much the agreement is negotiated. High-asset or heavily contested prenups are sometimes billed hourly ($250–$400) instead, because the back-and-forth makes the scope unpredictable.
Why each spouse needs their own attorney
A single lawyer cannot ethically represent both partners on a prenup, and an agreement signed without independent advice for the less-wealthy spouse is much easier to challenge later. So in practice each spouse retains their own attorney — one drafts the agreement and the other reviews it and advises their client. That means most couples pay two fees, though the reviewing attorney’s fee is usually lower than the drafting attorney’s.
Attorney fees vs. court costs — and the cost of skipping a prenup
A prenup is a private contract, not a court filing, so unlike most legal matters there are no court costs or filing fees — what you pay is purely the attorneys’ fees for drafting, disclosure, and review. It helps to weigh that fee against the alternative: without a prenup, property division at divorce defaults to your state’s rules and can require expensive litigation. A few thousand dollars now can prevent far larger legal bills later.
State law and enforceability: the Uniform Premarital Agreement Act
Whether a prenup holds up depends on your state. About half the states have adopted the Uniform Premarital Agreement Act (UPAA) or its successor, the UPMAA, which set relatively consistent standards — generally requiring that the agreement be signed voluntarily and with fair financial disclosure. The remaining states apply their own statutes and case law, which can impose stricter or different requirements. Either way, full disclosure, independent counsel, and signing well before the wedding are what make a prenup enforceable.
Frequently asked questions
Drafting a prenup is usually a flat attorney fee of about $1,000–$2,500 for a straightforward agreement, rising to $3,000–$7,500 or more when there are significant assets, a business, or heavy negotiation. Because each spouse should have their own attorney, most couples pay two fees.
A simple prenup commonly costs $1,000–$2,500 per attorney in flat fees, and complex or negotiated agreements run higher. Since both partners should have independent counsel, a couple’s total is often the drafting fee plus a lower reviewing fee.
Most charge a flat fee to draft or review a prenup, so the price is predictable. Hourly billing ($250–$400) is reserved for high-asset agreements or those with extensive back-and-forth negotiation.
Effectively yes. One attorney cannot represent both partners, and independent legal advice for each spouse is one of the things that makes a prenup enforceable. The drafting attorney represents one partner; the other should have their own attorney review it.
Often the flat fee is paid up front or split into a deposit and a balance at signing. For hourly engagements a retainer is paid first. Many attorneys offer a payment schedule — ask before you sign.
More assets mean more to document and protect — a business valuation, real estate, investments, or separate property each require careful drafting and full financial disclosure, and they usually prompt more negotiation between the two attorneys, all of which adds time and cost.
No. A prenuptial agreement is a private contract that is not filed with a court, so there are no court or filing fees. What you pay is purely the attorney fee for drafting, disclosure, and review.
The flat fee for a standard prenup is fairly standardized locally, but you can compare quotes, ask exactly what the fee covers, and — for a simple agreement — discuss a fixed scope so the cost does not creep up with revisions.
Agree on the key terms with your partner first, gather your financial disclosures in advance, keep the agreement straightforward, and start early so there is no rush. The less drafting and negotiation the attorneys must do, the lower the fee.
You can, and online templates exist, but a do-it-yourself prenup is far more likely to be challenged or thrown out for missing disclosure, improper drafting, or lack of independent counsel. The legal fee largely buys enforceability — the thing a prenup exists to provide.
For many couples, yes — especially with a business, significant or separate assets, children from a prior relationship, or a large income gap. A few thousand dollars for a solid prenup can prevent far more expensive divorce litigation and uncertainty later.
Reviewing a prenup the other side prepared is cheaper than drafting one — often a few hundred to around a thousand dollars — because the attorney is advising on an existing document rather than building it from scratch.
Yes. Attorney rates track the local cost of living, and your state's law governs enforceability: about half the states follow the Uniform Premarital Agreement Act, while the rest apply their own rules on disclosure and fairness. Enter your ZIP above for localized context.
