Typical Cost Ranges for Prenups
The cost of a prenuptial agreement ranges from about $500 to $10,000 or more, depending on your approach. DIY templates cost the least, while hiring two lawyers for full representation costs the most.
On average, if both partners hire separate attorneys, you can expect to pay $2,500 to $7,500 total. In high-asset situations or complex financial structures, costs can easily exceed $10,000.
Here are the common price ranges for each method:
- DIY template or online service: $50–$300 (plus filing fees if any)
- Mediation or collaborative law: $1,500–$5,000 total (split between partners)
- One lawyer drafting for both (rarely recommended): $1,000–$3,000
- Two separate lawyers (most common and safest): $2,500–$7,500
- High-net-worth or complex assets: $10,000–$20,000+
What Drives the Cost Up?
The main cost driver is the complexity of your finances. If you own a business, have real estate, retirement accounts, inheritances, or significant debt, a lawyer will need more time to draft and negotiate.
Another factor is whether you and your partner have conflicting interests. If negotiations are contentious, lawyers may need to go back and forth, increasing billable hours.
Geographic location also matters. Attorney rates in major cities like New York or San Francisco are higher than in rural areas. Expect $300–$500 per hour in metro areas, versus $150–$300 elsewhere.
- Number of assets and debts to address
- Ownership of a business or professional practice
- Future income potential (e.g., stock options, royalties)
- Whether you have children from prior relationships
- The level of negotiation required between both parties
Breaking Down the Costs by Approach
If you choose a DIY template, you'll pay a low flat fee, but you risk missing important state-specific requirements or making the agreement unenforceable. This can be a costly mistake later.
Mediation involves a neutral third party who helps you both reach an agreement. You might still have lawyers review the final document, adding to the cost but ensuring fairness.
Hiring two separate lawyers is the gold standard. Each partner gets independent advice, which courts view favorably. The cost includes drafting, negotiation, and revisions.
- DIY: cheapest upfront, but highest risk of invalidity
- Mediation: moderate cost, good for cooperative couples
- Two lawyers: highest cost, best protection for both parties
- One lawyer drafting for both: not recommended, as it creates a conflict of interest
Hidden Costs and Additional Fees
Beyond attorney fees, you may encounter costs for notarization, filing fees (though most states don't require filing), and financial appraisals. For example, if you need to value a business or real estate, an appraiser may charge $500–$2,000.
If you need to revise the agreement later (e.g., after a child is born or a career change), updates can cost $500–$1,500 each time. Consider future modifications when budgeting.
Also, some states require that the agreement be signed with a certain number of days before the wedding, so rushing can lead to expedite fees or additional lawyer hours.
- Notarization: $10–$50 per signature
- Business or property appraisal: $500–$2,000
- Financial documentation gathering (accountant fees): $200–$500
- Filing fees (if your state requires): $50–$200
- Post-marriage amendments: $500–$1,500 each
How to Save Money Without Sacrificing Quality
Start early. The more time you have, the less you'll pay in expedited services and rushed legal work. Begin discussions at least 3–6 months before the wedding.
Be transparent and organized. Gather all financial documents (bank statements, tax returns, property deeds) before meeting with a lawyer. This reduces billable hours spent on discovery.
Consider using a flat-fee attorney who offers a package for prenups, rather than an hourly rate. Many family lawyers offer flat fees ranging from $2,000 to $5,000 for straightforward cases.
- Shop around and compare quotes from at least three attorneys
- Use a prenup questionnaire to collect information efficiently
- Avoid making the agreement overly detailed if not necessary
- If your situation is simple, consider mediation instead of full representation
- Never sacrifice legal review just to save money—it can backfire
When It's Worth Paying More
If you have a high net worth, a family business, or significant future earning potential, paying for experienced counsel is a wise investment. A poorly drafted prenup can be challenged and thrown out, leaving you exposed.
Similarly, if there are children from previous relationships, you'll want to protect their inheritance rights. This requires careful drafting that goes beyond a basic template.
Remember, a prenup is a contract that lasts for decades. Spending an extra $2,000 now could save you tens of thousands in divorce litigation later.
- High net worth: investments, multiple properties, or significant savings
- Business ownership: protection of company shares and future profits
- Blended families: ensuring children from prior marriages are provided for
- Potential inheritance: keeping family wealth separate
- Spousal support waivers: complex legal standards in some states
