Prenuptial vs Postnuptial

Prenuptial agreements are signed before marriage and define property rights from the start Postnuptial agreements are signed after marriage — useful when circumstances change significantly Both types require full financial disclosure from each party to be enforceable Each party should have independent legal counsel for the agreement to hold up in court

What Agreements Typically Cover

Classification of pre-marital assets, debts, and business interests as separate property Treatment of income earned during the marriage and how savings are categorized Division of property and spousal support provisions in the event of divorce Protection of family wealth, trusts, and expected inheritances from commingling

Financial agreements are planning tools that protect both parties, not signs of distrust Equity compensation, business interests, and significant assets make agreements especially important Both parties need independent legal counsel and full financial disclosure for enforceability Consult a financial advisor to ensure the agreement aligns with your broader wealth plan

Why Financial Agreements Matter

Without an agreement, state law (community property or equitable distribution) determines asset division
Pre-marital assets, business interests, and future inheritance can be clearly classified and protected
Startup equity and stock options granted before or during marriage add complexity that default laws handle poorly
Agreements reduce conflict and legal costs if circumstances change, protecting both parties

Equity Compensation Complexity

Stock options granted before marriage but exercised during may be partially marital property
RSUs that vest during the marriage are generally considered marital/community property
An agreement can specify how pre-marital grants are treated if they vest or are exercised post-marriage
Clearly define how appreciation on separate property is classified — this varies significantly by state

Enforceability Considerations

Agreements signed under duress, without full disclosure, or without independent counsel may be invalidated
Unconscionable terms (leaving one party destitute) can make agreements unenforceable
Some states require agreements to be signed well in advance of the wedding (not the night before)
Regular review and updates strengthen enforceability as financial circumstances evolve
