Prenuptial Agreement Cost Estimator

How to Use This Tool

Enter your lead attorney’s hourly rate, then select the complexity level of your combined assets from the dropdown menu. Input the estimated number of draft revisions you expect, and indicate whether your partner will retain their own separate attorney. Add your county’s prenuptial agreement filing fees, and note if mediation is required for your negotiations. Click Calculate Estimated Cost to see a full breakdown of projected expenses, or Reset Form to clear all inputs.

Formula and Logic

Total estimated cost is calculated by summing five core components:

• Drafting Fees: Base hours for initial prenup drafting (4-24 hours depending on asset complexity) multiplied by your lead attorney’s hourly rate.
• Revision Fees: 1 hour of attorney time per expected draft revision, multiplied by the lead attorney’s hourly rate.
• Partner Attorney Fees: If your partner retains separate counsel, this is calculated as 50% of total drafting and revision fees to account for independent review and negotiation.
• Mediation Fees: Fixed rate of $200 per hour for mediation sessions, with 4 hours billed for 1-2 sessions and 8 hours billed for 3+ sessions.
• Filing Fees: Flat county filing fee you input, added directly to the total.

All values are added together to produce the total estimated cost. This is a simplified model for planning purposes only.

Practical Notes

Prenuptial agreement costs vary significantly by U.S. jurisdiction, as state laws and local filing requirements differ. For example, prenups in California or New York typically cost 20-30% more than in rural states due to higher attorney rates and stricter disclosure requirements. Always verify that your prenup complies with your state’s Uniform Premarital Agreement Act (UPAA) guidelines, as invalid prenups can be thrown out in court. If you have business interests, retirement accounts, or child support obligations from prior relationships, you may need additional specialized legal review that this tool does not account for.

Why This Tool Is Useful

Planning for prenuptial agreement expenses helps couples avoid unexpected legal bills during wedding planning. This tool breaks down costs into transparent categories, so you can identify areas to adjust (such as reducing revisions or opting for shared mediation) to fit your budget. It also helps you compare quotes from different attorneys by providing a baseline for what each service component should cost. Small business owners with complex assets will find the asset complexity dropdown particularly useful for estimating added legal time for business valuation or ownership clauses.

Frequently Asked Questions

Do I need a lawyer to draft a prenuptial agreement?

While some states allow pro se (self-represented) prenup drafting, most courts require each party to have independent legal representation to validate the agreement. Using a qualified attorney also ensures your prenup complies with state laws and includes all necessary financial disclosures to avoid being invalidated later.

Are prenuptial agreement filing fees refundable?

Filing fees are paid to your county clerk’s office and are rarely refundable, even if you withdraw the prenup before finalization. Check with your local clerk’s office for specific refund policies, as these vary by county.

Can I use one attorney for both parties to save money?

While sharing an attorney will lower upfront costs, it creates a conflict of interest that can invalidate the prenup. Most states require each party to have their own independent attorney to ensure the agreement is fair and voluntarily signed. This tool accounts for that added cost when you select the separate attorney option.

Additional Guidance

This tool provides estimates only and does not constitute legal advice. Always consult a qualified family law attorney in your jurisdiction before finalizing a prenuptial agreement. Laws and filing fees change regularly, so verify all rates and requirements with local court and bar association resources. Keep records of all legal invoices and filings to track actual costs against your estimate. If your financial situation changes significantly during the drafting process, rerun the calculator with updated inputs to adjust your budget.
