How Much Does a Prenup Cost?

Prenup costs depend on the complexity of your financial situation. A simple prenup averages around $1,500, while complex agreements involving businesses or high net worth can exceed $10,000. Remember: each spouse should have their own attorney, so total costs reflect two sets of legal fees.

Simple Prenup

$1,000–$3,000

Few assets, straightforward terms

Complex Prenup

$5,000–$10,000+

Business, trusts, high net worth

Complexity Low High Average Notes
Simple (few assets, no business) $1,000 $3,000 $1,500 Straightforward agreements with limited assets and no complex provisions
Moderate (some assets, property) $2,500 $6,000 $3,500 Includes property division, retirement accounts, spousal support clauses
Complex (business, trusts, high net worth) $5,000 $10,000 $7,500 Business valuation, trust provisions, multi-state property, detailed alimony formulas
High-net-worth / celebrity $10,000 $50,000 $25,000 Ultra-high-net-worth individuals, multiple business entities, international assets
Online / DIY prenup service $200 $800 $500 Template-based services; may not meet state-specific requirements or hold up in court

Prenup Enforcement: How Often Are They Upheld?

Prenuptial agreements are upheld approximately 88% of the time when they reach court. Only 4% of challenged prenups are fully invalidated. The key to enforceability: independent legal counsel for both parties, full financial disclosure, and signing well before the wedding.

Frequently Asked Questions

What percentage of couples get a prenup?
Approximately 15% of U.S. couples currently have a prenuptial agreement, according to AAML surveys and the 2022 Harris Poll. This is up from roughly 3% in 2000. The rate is significantly higher among couples entering second or subsequent marriages (44%) and those with household incomes above $200,000 (35%).
How much does a prenup cost on average?
The average prenup costs about $2,500, but the range varies widely. A simple prenup with few assets typically runs $1,000 to $3,000, while complex agreements involving businesses, trusts, or high net worth can cost $5,000 to $10,000 or more. Each spouse should have their own attorney, so the total cost covers two lawyers. Online DIY services charge $200 to $800 but may not meet state-specific requirements.
Are prenups enforceable? How often are they upheld?
Prenups are generally enforceable and upheld approximately 88% of the time (58% exactly as written, 30% with minor modifications). Only about 4% are fully invalidated. The most common reasons for invalidation are: lack of independent legal counsel (35% of challenges), failure to fully disclose assets (25%), and signing under duress (20%). Following the Uniform Premarital Agreement Act (UPAA), adopted by 28 states, significantly improves enforceability.
Are millennials more likely to get prenups?
Yes. AAML member attorneys reported a dramatic increase in millennial clients requesting prenups beginning around 2016. Millennials (ages 30–44) are the most likely generation to both consider a prenup (46%) and actually have one (20%), according to the 2022 Harris Poll. This generation’s higher rates are attributed to marrying later, having more pre-marital assets, student debt awareness, and growing up during the high-divorce era of the 1990s.
Can a prenup be signed after marriage?
A prenuptial agreement must be signed before the marriage to be valid. However, couples can sign a postnuptial agreement after marriage, which serves a similar purpose. Postnuptial agreements are enforceable in most states, though some states (such as Ohio) have stricter requirements. Courts may scrutinize postnups more carefully than prenups because of the fiduciary duty between spouses.
What can't be included in a prenup?
Prenups cannot include provisions about child custody or child support, as courts always decide these based on the child’s best interest at the time of divorce. Most states also prohibit clauses that incentivize divorce, provisions deemed unconscionable, or anything illegal. “Lifestyle clauses” (such as penalties for infidelity or weight gain) are included in about 15% of prenups but are frequently unenforceable.
How far before the wedding should you get a prenup?
Attorneys and the AAML recommend finalizing a prenup at least 30 to 60 days before the wedding. Signing too close to the ceremony is one of the most common reasons prenups are challenged, as courts may view it as a sign of duress or coercion. Some attorneys recommend starting the process 3 to 6 months before the wedding to allow time for negotiation, financial disclosure, and independent legal review.
Do prenups hold up in all states?
Prenup enforceability varies by state. Twenty-eight states and the District of Columbia have adopted the Uniform Premarital Agreement Act (UPAA), which provides consistent standards. States that have not adopted the UPAA, such as New York and Florida, have their own common-law frameworks. Community property states (California, Texas, Arizona, etc.) and equitable distribution states may interpret certain provisions differently. Having each party represented by independent counsel is the single most important factor for enforceability across all states.
Who initiates the prenup conversation?
The gender dynamics of prenup initiation have shifted dramatically. In 2010, men initiated 68% of prenup conversations. By 2022, women initiated 42% of prenup conversations, men initiated 36%, and 22% were mutual decisions, according to AAML surveys. This shift reflects women’s increasing financial independence, higher earnings, and growing entrepreneurship rates.
Does getting a prenup mean you expect to divorce?
No. Research does not support the idea that prenups increase divorce risk. The AAML notes that most couples who get prenups describe the process as clarifying financial expectations and actually improving communication about money. Common analogies include buying homeowner’s insurance (you don’t expect a fire) or writing a will (you don’t expect to die soon). Financial disagreements are a leading cause of divorce, and prenup conversations can help couples address these issues proactively.
