Formula and Logic
This tool calculates total prenuptial agreement costs using industry-standard rate structures for U.S. family law practices:
- Base Jurisdiction Cost: Fixed starting rate for prenup drafting in your selected state, based on 2024 average solo practitioner rates.
- Asset Complexity Adjustment: Base cost multiplied by a complexity multiplier (1x for simple, 1.5x for moderate, 2.5x for complex) to account for additional document review and negotiation.
- Attorney Type Adjustment: Base cost multiplied by a firm size multiplier (1x for solo, 1.8x for mid-sized, 3x for large firms) to reflect billing rate differences.
- Revision Costs: $300 per revision round, covering attorney time for document updates and client consultations.
- Notarization Fee: $150 flat fee for required notary services (waived if not required in your jurisdiction).
- Filing Fee: Local court fee for filing the executed prenuptial agreement, entered manually as this varies by county.
Total Estimated Cost = Base Cost + Complexity Adjustment + Attorney Adjustment + Revision Costs + Notarization Fee + Filing Fee.
Practical Notes
Prenuptial agreement costs vary widely based on individual circumstances and local regulations:
- Jurisdiction matters: States like California and New York have higher base rates due to higher cost of living and more complex marital property laws.
- Community property states (AZ, CA, ID, LA, NV, NM, TX, WA, WI) may require additional clauses for separate vs. marital assets, increasing complexity costs.
- Small business owners or individuals with international assets should select "Complex" asset complexity, as these require specialized legal review.
- Filing fees are set by local county courts and range from $100 to $400 across most U.S. jurisdictions.
- This estimate covers drafting and basic negotiation only; contested prenups or mediation will incur additional costs not included here.
Always consult a qualified family law attorney in your jurisdiction to confirm requirements and final costs. This tool does not provide legal advice.

Frequently Asked Questions
Is this estimate legally binding?
No, this tool provides a cost estimate only. It does not constitute legal advice, and final costs will be set by your retained attorney. Always sign a formal fee agreement with your lawyer before work begins.
Do I need a prenuptial agreement?
This tool does not advise on whether you need a prenup. Consult a qualified family law attorney to discuss your specific financial situation, state laws, and personal needs.
Can I use this estimate for a postnuptial agreement?
Postnuptial agreements (signed after marriage) typically cost 10-20% more than prenuptial agreements due to additional legal complexity. Adjust your estimate upward if using this for postnuptial planning.
