What Is a Prenuptial Agreement?

A prenuptial agreement is a legally binding contract created by a couple before marriage that establishes how assets, debts, and financial matters will be handled during the marriage and in the event of divorce or death. It provides clarity and protection for both parties, particularly regarding pre-marital assets, business interests, and inheritance rights.

The cost of creating a prenuptial agreement varies widely based on complexity, attorney fees, and geographic location. Simple agreements with few assets may cost under $1,500, while complex agreements involving businesses, real estate, and multiple asset classes can exceed $10,000. Having separate legal representation for both parties is recommended.

Prenuptial Agreement Cost Formula

Total Cost = (Attorney Hourly Rate × Estimated Hours × Complexity Multiplier) + Filing Fees + Notary Costs

Complexity multipliers: Simple = 1.0, Moderate = 1.5, Complex = 2.5

The complexity multiplier accounts for additional research, negotiation, and drafting time required for more sophisticated agreements involving business valuations, international assets, or complex estate planning considerations.
