What to Watch For in a Prenuptial Agreement—And When to Revisit It

What to Watch For in a Prenuptial Agreement—And When to Revisit It

Protecting Caregiving Spouses, Managing Separate Earnings, and Lessons from Belle Burden’s ‘Strangers’ 

When clients in New York City ask us about prenuptial agreements, there is often a lingering assumption that prenups are strictly for the ultra-wealthy, or that they only matter if a marriage ends in hostility. 

However, following the release of Belle Burden’s bestselling memoir Strangers, we have seen a dramatic surge in inquiries from educated, professional women and couples across Manhattan and Brooklyn. Burden was an attorney herself, raised in New York, and the beneficiary of substantial generational wealth. Yet when her 20-year marriage disintegrated, her prenuptial agreement did not function as the protective shield she envisioned. Instead, it left her severely exposed. 

Burden’s experience highlights a critical reality of marital contracts: a prenuptial agreement executed by two unencumbered young professionals rarely fits the reality of a marriage 10 or 20 years later—especially once children arrive and careers diverge. 

While our practice centers on estate planning and wealth preservation, prenuptial agreements govern how property rights are classified during life, upon divorce, and at death. Understanding standard prenup clauses—and knowing when an agreement has outlived its original intent—is essential to protecting your long-term independence. 

What Is a “Separate Earnings” Clause in a New York Prenup? 

Direct Answer (DRL § 236B): A “separate earnings” or “waiver of marital property” clause overrides New York’s default equitable distribution laws by dictating that all earned income, bonuses, deferred compensation, and investments acquired by either spouse during the marriage remain the sole, separate property of the earning spouse. 

Under standard New York law (Domestic Relations Law § 236B), income earned by either spouse during the marriage is considered marital property. In the event of a divorce without a prenup, a New York court distributes that accumulated wealth equitably between both parties, recognizing non-financial contributions such as homemaking and childcare. 

Many standard prenuptial agreements, however, waive this protection. They include clauses stating that: 

  • Individual Retention: Each party retains their individual compensation, business profits, and retirement accounts as separate property. 
  • Sole Titling Governance: Any asset titled solely in one spouse’s name remains that spouse’s exclusive property upon dissolution. 
  • Strict Marital Property Limits: Only assets voluntarily placed in joint title will be considered marital property. 

On the surface, this appeals to ambitious young couples: “What’s mine is mine, and what’s yours is yours.” But as Strangers demonstrated, this clause contains an enormous structural trap. 

The Child Penalty: How Belle Burden’s Prenup Backfired 

In Strangers, the prenuptial agreement was originally proposed to protect Burden’s family trust assets. Late in the negotiations, however, terms were inserted allowing each spouse to retain everything they earned during the marriage in their own name. Against her attorney’s advice, she signed it. Over the next two decades, their roles shifted: 

  • The Caregiving Trade-Off: Burden stepped back from her legal career to raise their three children and manage the domestic sphere, taking on occasional pro bono legal work. 
  • The Wealth Accumulation: Her husband pivoted into finance, eventually becoming a partner at a hedge fund and accumulating millions of dollars. 
  • The Asymmetric Result: Because he deposited his earnings into separate accounts and investments in his sole name, the prenup gave Burden zero legal claim to the vast marital wealth generated during their marriage. 

She carried the financial and career sacrifice of unpaid caregiving, while he captured 100% of the financial upside. At the same time, her separate inherited trust distributions were placed into jointly titled real estate, exposing her family wealth to division. It was the worst of both worlds. 

How to Protect the Caregiving Spouse in a Prenup 

A fair prenuptial agreement must anticipate life milestones rather than remain frozen in time. If one partner is likely to step back from full-time employment—or if you simply want an agreement that evolves with your family—consider including the following protective clauses:

Prenup Mechanism How It Functions Practical Benefit for NY Couples
Child-Triggered Conversion Clause Automatically modifies or voids separate earnings provisions upon the birth or adoption of a child. Shifts the marriage into equitable distribution once children arrive, preventing caregiver economic abandonment.
Workplace Departure Adjustment Calculates a mandatory lump-sum payment or defined percentage of annual income credited to the spouse who scales back work. Quantifies and compensates the actual economic cost of stepping off the NYC career ladder.
Tiered Duration Sunsets Gradually phases out asset waivers at specific marital milestones (e.g., 5, 10, or 15 years). Reflects the deepening economic interdependence of long-term partnerships.
Mandatory Joint Capital Accounts Requires the higher-earning spouse to fund a joint investment vehicle annually during the marriage. Guarantees that liquid wealth is accumulated under joint ownership regardless of individual title.

When Must You Revisit Your Prenuptial Agreement? 

A prenuptial agreement is not a “set-it-and-forget-it” document. Life transitions alter the financial assumptions that underpinned the original contract. You should review and potentially amend your marital agreement when any of the following events occur: 

1. The Birth or Adoption of Children 

Having children is the single largest disruptor of career parity. If your prenup keeps earnings separate, having a child immediately introduces economic vulnerability for whichever partner assumes primary caregiving responsibilities. 

2. Significant Career Changes or Asymmetric Wealth Accumulation 

If one spouse founds a business, transitions from a salaried role to a lucrative partnership (such as private equity, hedge funds, or big law), or leaves the workforce entirely, the economic balance of the household fundamentally changes. 

3. Substantial Inheritances or Trust Payouts 

If one spouse anticipates receiving substantial distributions from a family trust or inheritance, the couple should confirm how those distributions will be treated, how real estate purchases will be titled, and whether separate property credits are explicitly preserved. 

4. Relocating to or from New York 

Marital agreements are interpreted according to state law. If you signed an agreement in California (a community property state) and moved to New York (an equitable distribution state), choice-of-law and enforcement provisions must be examined to ensure they operate as intended. 

How to Update an Agreement During Marriage: The New York Postnup 

If your current prenuptial agreement is outdated, unfair, or no longer reflects your family dynamic, you can modify or revoke it using a New York Postnuptial Agreement. 

Under New York Domestic Relations Law § 236B(3), married couples are legally permitted to enter into postnuptial contracts to define separate and marital property, establish maintenance, or formally revoke a pre-existing prenup. However, New York courts scrutinize postnups far more rigorously than prenups: 

  • Strict Acknowledgment Formalities: A postnuptial agreement in New York must be in writing, subscribed by the parties, and acknowledged with the exact same formality required to record a deed in the state (NY DRL § 236B(3)). A standard notary stamp without proper certificate of acknowledgment language will render the agreement void. 
  • Independent Legal Counsel: Both spouses must have their own independent legal representation. Using one attorney or having one spouse pay for a perfunctory review creates grounds for having the agreement vacated. 
  • Full Financial Disclosure: Both spouses must exchange complete, transparent sworn statements of net worth. Hiding assets or failing to disclose business interests can lead a court to strike down the postnup. 

Frequently Asked Questions: Prenups, Postnups, and Strangers 

What prenup mistake did Belle Burden make in Strangers? 

Belle Burden agreed to a clause allowing each spouse to keep whatever they earned during the marriage as separate property. When she stepped back from her legal career to raise their three children and her husband earned millions in finance, she had no legal claim to the marital wealth generated during their 20-year marriage. 

Can a prenuptial agreement include a clause that changes if you have children? 

Yes. Couples frequently include conditional provisions—such as child-triggered sunset clauses—that either revoke separate earnings waivers or mandate structured spousal support and asset transfers once children are born or adopted. 

Is it possible to change or cancel a prenuptial agreement after getting married in New York? 

Yes. Under New York DRL § 236B(3), spouses can execute a valid postnuptial agreement that amends, updates, or completely rescinds their prenuptial agreement. It requires strict statutory deed formalities, full financial disclosure, and independent legal representation for both spouses. 

Does a prenuptial agreement protect an inheritance in New York? 

An inheritance is separate property under New York law by default, but a prenuptial agreement provides enhanced protection by establishing clear rules against accidental transmutation. It ensures that using separate inherited funds for living expenses or real estate does not inadvertently create a gift to the marriage. 

What happens if you sign a prenup against your lawyer’s advice in New York? 

If you sign an agreement against your attorney’s advice—as Belle Burden did—the agreement is generally still binding and enforceable under New York law unless you can prove severe fraud, duress, or unconscionability at the time of execution. Courts strongly favor enforcing voluntarily executed marital contracts.
