The Importance of Severability Clauses in Prenuptial Agreements

A well-drafted prenuptial agreement is one of the most effective tools for protecting assets and clarifying financial expectations before marriage. However, even the most carefully crafted prenup faces potential legal challenges. If a court determines that one provision violates public policy or state law, the entire agreement could be invalidated—unless it includes a severability clause.

This is why experienced matrimonial attorneys insist on including severability clauses in every prenuptial agreement. Let’s explore what these clauses do, why they matter, and how they’ve worked in real cases.

What Is a Severability Clause?

A severability clause is a provision in a contract that protects the validity of the entire agreement if any portion is found to be unenforceable or invalid. In simpler terms, it says: “If one part of this agreement is struck down by a court, the rest of the agreement should survive and remain enforceable.”

Alternative names: Severability clauses are also called “saving clauses” or “blue pencil clauses.”

Basic language: A typical severability clause might read:

“If any provision of this Agreement is held to be invalid, void, or unenforceable by a court of competent jurisdiction, such provision shall be severed from this Agreement, and all other provisions shall remain in full force and effect unless the severed provision is so material that the parties would not have agreed to the remainder without it.”

Why Severability Clauses Matter in Prenuptial Agreements

1. Protects Your Overall Agreement

Without a severability clause, a single problematic provision could invalidate the entire prenuptial agreement. Consider this scenario:

A prenup includes provisions addressing property division, maintenance, and child support. A court determines that the child support provision violates public policy (courts generally won’t enforce agreements that eliminate a parent’s obligation to support children). Without a severability clause, the entire prenup could be voided, losing all protection on property and maintenance issues.

With a severability clause, only the child support provision is severed, and the property and maintenance terms survive.

2. Enforces the Parties’ Intent

Severability clauses demonstrate that both parties intended the agreement to survive even if one provision fails. This reinforces the parties’ clear intent to be bound by the remaining terms, which courts consider when deciding how to treat a partially invalid agreement.

3. Provides Efficiency

Instead of relitigating the enforceability of the entire agreement, a severability clause allows courts to quickly move past the invalid provision and enforce the rest. This saves time, legal fees, and uncertainty.

4. Protects Against Changing Legal Standards

Family law evolves. A provision that was enforceable when the prenup was drafted might face legal challenges years later if the law changes. A severability clause ensures that valid provisions remain enforceable even if others become problematic.

Common Challenges to Prenuptial Provisions

Understanding what provisions might be challenged helps explain why severability clauses are so important:

Child Support and Custody

Courts will not enforce provisions that waive, limit, or condition child support based on custody arrangements. Any attempt to trade custody for financial advantages is viewed as contrary to the children’s best interests and will be struck down.

Example: A prenup states, “The wife waives all right to child support in exchange for 70% of marital assets.” This provision is unenforceable and would be severed. The wife would still have the right to seek child support based on the statutory guidelines.

Limits on Maintenance Based on Fault

While prenups can address maintenance amounts and duration, provisions that condition maintenance on marital conduct or fault are increasingly scrutinized. New York’s “no fault divorce” law has reduced emphasis on fault, making such provisions questionable.

Overly One-Sided Provisions

If a provision is unconscionable—so extremely one-sided that no reasonable person would agree—a court might strike it down as unenforceable.

Example: A provision that gives one spouse 95% of all marital assets while the other spouse gets 5%, with no consideration of the length of the marriage, contributions, or other factors, might be deemed unconscionable.

Provisions Violating Public Policy

Provisions that waive alimony entirely (rather than limiting it), that create incentives to divorce, or that restrict one spouse’s fundamental rights may violate public policy and be struck down.

Real-World Case Examples

Understanding how severability clauses work requires looking at actual cases:

Case 1: The Child Support Problem

In a recent New York case, a couple executed a prenuptial agreement that included detailed provisions about property division and maintenance but included a clause stating, “Neither party shall be obligated to provide child support beyond the statutory minimum.”

When the couple divorced 8 years later with three children, the wife sought child support beyond the guideline minimum based on the husband’s substantial income and the family’s affluent lifestyle. The husband pointed to the prenup’s child support waiver.

The court found this provision unenforceable (courts won’t permit waiving child support obligations). However, because the prenup included a strong severability clause, the court severed only that provision. The property and maintenance terms of the prenup remained enforceable, protecting the parties’ original intent regarding those issues.

Result: The child support was calculated under statutory guidelines without the waiver, but the prenup’s other provisions stood, saving the agreement from complete invalidation.

Case 2: The Maintenance Cap That Became Too Generous

Another case involved a prenuptial agreement drafted 20 years prior that capped maintenance at $1,000 per month if the marriage ended. At the time, this seemed reasonable given the parties’ income levels.

However, by the time of divorce, the husband’s income had grown to $500,000 annually, while the wife had remained a homemaker. The wife argued that the maintenance cap was unconscionable given the substantial change in circumstances and the enormous disparity in income.

The court found that while the cap was unconscionable under current circumstances, the prenup’s severability clause allowed the maintenance cap provision to be severed. The remaining provisions addressing asset division and other terms remained enforceable. The wife’s maintenance was calculated under current statutory guidelines rather than the outdated cap.

Result: The marriage’s length and current income levels were considered in calculating maintenance, but the prenup still provided protection for asset division and other terms.

Case 3: The Carefully Protected Prenup

This case illustrates a prenup with strong severability language that largely survived challenge. A substantial prenup addressed multiple important issues: property classification and division, maintenance amounts and duration, treatment of professional licenses and degrees, tax implications, and sunset provisions after 10 years of marriage.

When challenged, the court found one provision (a sunset clause that would eliminate maintenance after 10 years regardless of circumstances) potentially problematic under changed law. However, with a robust severability clause, the court severed only that provision and enforced the rest of the agreement substantially as written.

Result: The parties received most of the protection they bargained for, with only minor modifications to one provision.

Drafting a Strong Severability Clause

An effective severability clause should include several key elements:

1. Clear Statement of Intent

The clause should explicitly state that the parties intend the agreement to survive even if portions are invalidated.

2. Proportionality Language

The clause should indicate that the invalid provision will be severed in the narrowest way possible—removing only what’s problematic while preserving the rest.

Example language: “If any provision or portion thereof shall be found invalid or unenforceable, such provision shall be modified to the minimum extent necessary to make it enforceable, or if such modification is impossible, the invalid portion shall be severed.”

3. Alternative Language

Some severability clauses include alternative language addressing how a provision should be modified if it can be reformed rather than severed.

Example: “If any provision is found invalid, the parties authorize the court to modify the provision to make it enforceable, and such modified provision shall remain in effect.”

4. Materiality Analysis

A strong severability clause acknowledges that some provisions are more material than others and that severance should only occur if the invalid provision isn’t so essential that the parties wouldn’t have agreed to the agreement without it.

Best Practices for Prenuptial Severability

When working with an attorney to draft a prenup, several best practices will strengthen your agreement. First, include multiple severability provisions. In addition to a general severability clause, address specific provisions that might be challenged, such as child support or maintenance waivers. Second, demonstrate good-faith negotiation. Prenups are more likely to survive challenges if they demonstrate good-faith negotiation between the parties, and severability clauses should be accompanied by evidence of fair bargaining.

Third, use clear language throughout the severability clause. Avoid vague or ambiguous language that could complicate interpretation—legal precision protects enforceability. Fourth, address state-specific concerns carefully. New York has specific requirements for enforceable prenuptial agreements, and the severability clause should be drafted with these requirements in mind. Fifth, ensure both parties review carefully before signing. Both parties should review the severability clause and the entire agreement before signing, which demonstrates fairness and documents mutual intent. Finally, update periodically. While prenups don’t typically need frequent updates, reviewing the severability clause every 5-10 years ensures it reflects current law.

Limitations of Severability Clauses

While severability clauses are powerful tools, they do have important limitations to understand. First, material provisions matter significantly. If the provision struck down is so central to the agreement that the parties wouldn’t have agreed without it, even a severability clause may not save the remaining terms. Second, multiple problems can overwhelm the clause. If numerous provisions are struck down, courts might eventually conclude that the agreement’s essential purpose has been defeated, preventing wholesale enforcement of the remaining terms. Third, equitable considerations apply. Courts retain discretion to refuse severance if doing so would produce an unfair or inequitable result for one of the parties.
