How Much Does a Prenup Cost
A breakdown of prenuptial agreement costs — attorney fees, what affects the price, DIY vs attorney-drafted, and whether a prenup is worth the investment.
Updated March 10, 2026
Most prenuptial agreements cost between $1,500 and $10,000 total, depending on the complexity of your finances, where you live, and how much negotiation is involved.
If that sounds like a lot, consider this: the average contested divorce costs $15,000 to $50,000 or more. A prenup that costs a few thousand dollars today can save tens of thousands in legal fees if the marriage ends.
This guide breaks down where the money goes — from attorney fees to negotiation costs — and shows you practical ways to manage the price. If you are new to prenuptial agreements, start with our complete guide to prenuptial agreements.
Typical Prenup Costs
The total cost depends on how complicated your financial situation is and how much negotiation is needed. Here are the three most common scenarios.
Simple prenup. Straightforward finances, modest savings, no business ownership. Both parties agree on the major terms before involving attorneys. Cost: $1,500 to $3,000 per spouse.
Moderate prenup. One or both spouses own a business, have real estate, or need provisions for alimony or retirement accounts. Some negotiation and a few rounds of revisions. Cost: $3,000 to $7,000 per spouse.
Complex prenup. High-net-worth couples with multiple businesses, trusts, or international assets. Extensive negotiation, possibly involving financial experts. Cost: $7,000 to $15,000+ per spouse.
Remember: each spouse needs their own attorney. The costs above are per person, so double them for the total bill.
| Prenup Complexity | Cost Per Spouse | Total Cost (Both Spouses) |
|---|---|---|
| Simple | $1,500-$3,000 | $3,000-$6,000 |
| Moderate | $3,000-$7,000 | $6,000-$14,000 |
| Complex | $7,000-$15,000+ | $14,000-$30,000+ |
Most couples fall in the simple to moderate range, paying $3,000 to $10,000 total.
What Affects the Price
Several factors push the cost up or down.
Complexity of assets. A prenup covering a checking account and a retirement fund is simpler than one addressing a family business, rental properties, stock options, and a trust. More assets mean more attorney hours.
Amount of negotiation. If both parties agree on key terms before attorneys get involved, the legal work is mostly drafting and reviewing. If attorneys are negotiating back and forth over alimony caps or business valuation clauses, costs climb quickly.
Geographic location. Family law attorneys in New York City or Los Angeles charge $350 to $600 per hour. In smaller cities, rates range from $200 to $350 per hour. The same prenup can cost twice as much in Manhattan as in Des Moines.
Attorney experience. A senior attorney charges more per hour but may work faster and catch issues a less experienced attorney would miss.
Number of revisions. Each round of changes requires both attorneys to review the updated document. Two or three rounds costs far less than seven.
Cooperation between parties. When both partners approach the process in good faith, the work goes faster. If one party stalls or makes unreasonable demands, the process takes longer and costs more.
Attorney Fees vs. DIY Prenups
The gap between an attorney-drafted prenup and a do-it-yourself option is significant — in both price and protection.
Online prenup services charge $200 to $1,000. You answer questions online, and the service generates a document based on your responses.
Attorney-drafted prenups start at $1,500 per spouse. Your attorney tailors the agreement to your specific situation, your state’s laws, and your goals.
The risks of DIY:
- Enforceability. Courts scrutinize prenups closely, and a document that does not meet your state’s specific requirements may be thrown out entirely. Template-based services use generic language that may not comply with local law.
- Missing provisions. A template cannot anticipate the specific provisions you need. It may fail to address business interests, inheritance expectations, or spousal support in a way that protects you.
- No independent counsel. Courts are far more likely to enforce a prenup when both parties had their own attorney. A DIY prenup with no attorney involvement on either side is the easiest type to challenge.
When DIY might work: Both spouses have minimal assets, no business interests, no children from prior relationships, and agree completely on terms. Even then, have an attorney review the final document for $300 to $500.
When you need an attorney: Either spouse owns a business, has significant assets or debts, has children from a previous relationship, or wants alimony provisions. The cost of doing it right is far less than the cost of a prenup that falls apart in court.
How to Reduce Prenup Costs
These strategies help you keep costs manageable without sacrificing quality.
Agree on major terms before hiring attorneys. Discuss the big-picture issues with your partner first: property division, business interests, alimony provisions. When attorneys start with a framework rather than a blank slate, they work faster.
Organize financial documents in advance. Gather bank statements, tax returns, retirement account balances, debt records, and business financials before your first attorney meeting. Every hour your attorney spends chasing documents is an hour you pay for.
Use a flat-fee attorney. Some family law attorneys offer flat-fee pricing for prenups. A flat fee gives you cost certainty and eliminates the anxiety of a running hourly meter.
Limit revisions. Each round of changes costs money on both sides. Focus on substantive issues rather than minor wording preferences.
Start early. Rushing a prenup costs more. Attorneys charge premium rates for rush work. Begin the process at least three to six months before the wedding.
Is a Prenup Worth the Cost?
The simplest way to evaluate whether a prenup is worth it: compare the cost of getting one to the cost of not having one.
A contested divorce in the United States costs $15,000 to $50,000 or more in attorney fees, court costs, and expert fees. Property division disputes, alimony fights, and business valuation battles are the most expensive parts of any divorce. A prenup that addresses those issues in advance takes them off the table. For a full breakdown, see our guide on how much divorce costs.
A $5,000 prenup can save $50,000 or more in divorce litigation. That is a 10-to-1 return — and it does not account for the emotional cost of a prolonged court battle.
Prenups are not just for wealthy people. A couple with $80,000 in combined student debt and a small 401(k) has just as much reason to clarify financial expectations as a couple with $5 million in the bank. Anyone with assets, debts, or a business benefits.
A prenup also provides clarity during the marriage. Both partners know the financial ground rules. Fewer surprises, fewer assumptions, and a stronger foundation for financial decision-making.
Frequently Asked Questions
Can I get a prenup for free?
There is no way to get a professionally drafted prenup for free. Some online services offer basic templates at no cost, but these carry significant enforceability risks. If cost is a concern, look for attorneys who offer flat-fee pricing for simple prenups, which can start as low as $1,500 per spouse.
Do both parties need to pay for their own attorney?
Each party should have their own attorney. In some cases, one partner pays for both attorneys — but each attorney still represents only their own client. Courts look more favorably on prenups where both parties had independent legal counsel, so skipping a second attorney to save money can backfire.
Is an online prenup legally valid?
An online prenup can be legally valid if it meets your state’s requirements — written form, voluntary execution, full financial disclosure, and no unconscionable terms. However, online services use templates that may not account for state-specific rules, and the absence of independent attorneys makes the agreement easier to challenge. If you use an online service, have a family law attorney review the document before signing.
When should I start the prenup process?
Start at least three to six months before the wedding. This gives both parties time to hire attorneys, exchange financial disclosures, negotiate terms, and sign without time pressure. A prenup signed the week before the wedding is far more likely to be challenged on grounds of duress or coercion.
What to Do Next
Ready to move forward? Here is how to get started:
- Talk to your partner about the major terms you want to address. Agreeing on the basics before involving attorneys saves time and money.
- Gather your financial documents. Each of you should prepare a complete list of assets, debts, income, and financial obligations.
- Set a timeline. Work backward from your wedding date and allow at least three to six months.
- Schedule a free consultation with a family law attorney to understand what a prenup will cost for your situation and how to get started.
