When a spouse dies, Ohio law usually gives the surviving spouse important rights to the deceased spouse's estate. Those rights may include an intestate share, an election against the will, an allowance for support, and the right to remain in the marital home for a period of time.

But a prenuptial agreement can change those default rules.

A carefully written and properly executed prenup may waive or limit what a surviving spouse receives. It may protect premarital assets, preserve inheritances for children from a prior relationship, or direct wealth toward a trust or other beneficiaries.

The key is coordination. A prenuptial agreement cannot work alone. It must align with the will, trust, beneficiary designations, and ownership records.

Ohio Law Gives a Surviving Spouse Default Rights

If a person dies without a valid will, Ohio's intestate succession law controls the distribution of probate assets. Under Ohio Revised Code Section 2105.06, the surviving spouse's share depends on the decedent's children and whether those children are also the surviving spouse's children.

For example:

• If the decedent leaves a spouse but no children or descendants, the spouse generally receives the entire intestate estate.
• If all surviving children are children of both spouses, the spouse generally receives the entire intestate estate.
• If the decedent leaves children who are not all children of the surviving spouse, the surviving spouse may receive a statutory dollar amount plus a percentage of the remaining estate.

When a person dies with a will, Ohio Revised Code Section 2106.01 allows the surviving spouse to elect whether to take under the will or under the statutory scheme in Section 2105.06. This is often called electing against the will.

The statutory election may provide up to one-half of the net estate when fewer than two children or descendants survive. If two or more children or descendants survive, the amount generally may not exceed one-third of the net estate.

These rights do not automatically apply to every asset a person owns. They primarily concern assets passing through probate. Still, they can significantly affect the estate's distribution.

A prenuptial agreement can rewrite these rules.

A Prenup Can Waive the Elective Share and Other Benefits

A prenuptial agreement is a contract made before marriage. It may address property ownership, debts, income, spousal support, and what happens when the marriage ends by divorce or death.

At death, a valid Ohio prenup may waive or modify a surviving spouse's:

• Right to elect against the will.
• Intestate share under Ohio Revised Code Section 2105.06.
• Rights under Ohio Revised Code Chapter 2106, including certain spousal elections.
• $40,000 allowance for support under Ohio Revised Code Section 2106.13.
• Right to remain in the marital residence without charge for one year under Ohio Revised Code Section 2106.15.
• Other claims or benefits expressly addressed by the agreement.

The $40,000 allowance is sometimes described informally as a “year's support” benefit. However, Ohio's current statute identifies it as an allowance for support. Section 2106.15 separately addresses the surviving spouse's right to remain in the “mansion house” for one year.

A prenup may provide that each spouse keeps separate property for his or her own children. It may require a surviving spouse to accept a specific inheritance. It may also state that the surviving spouse receives nothing from certain property, or nothing from the probate estate, beyond what the agreement provides.

The wording matters. A broad waiver may not have the same effect as a narrow waiver. Courts generally apply contract principles to interpret a valid prenuptial agreement. The agreement must say clearly what rights the parties intended to give up.

Ohio Courts Examine How the Prenup Was Made

A prenuptial agreement does not become enforceable merely because both spouses signed it. Ohio courts examine the circumstances surrounding its execution.

Ohio decisions, including Gross v. Gross and Vanderbilt v. Vanderbilt, identify several important considerations.

1. The Agreement Must Be Voluntary

Each person must have a meaningful opportunity to understand and consider the agreement. Fraud, duress, coercion, and overreaching can undermine enforceability.

Timing can matter. Presenting a prenup immediately before the wedding may create concerns if the other person has no realistic opportunity to obtain advice or postpone the ceremony.

Signing a document under pressure can create a serious dispute later. A better process begins early, allows time for questions, and gives each person the opportunity to consult independent counsel.

2. The Parties Must Make Full and Fair Disclosure

Each future spouse should disclose assets, debts, income, business interests, real estate, investments, and other significant financial information.

Ohio courts do not necessarily require an itemized valuation of every possession. But the parties must have full disclosure, or full knowledge and understanding, of the nature, value, and extent of the property involved.

A hidden business interest, undisclosed account, or understated debt can threaten the waiver at the center of the agreement.

3. The Terms Must Not Be Unconscionable

Courts examine whether the agreement was unconscionable when the parties entered into it. A provision may be unfavorable without automatically being invalid. But extreme unfairness combined with inadequate disclosure or pressure can create a substantial problem.

The court looks at the agreement and the surrounding facts. It considers what each person knew, what each person understood, and whether the agreement resulted from a fair process.

4. The Circumstances Must Support Fairness

Ohio courts consider whether the parties entered the agreement with good faith and a fair understanding of its consequences. A spouse may agree to receive less than he or she would otherwise receive under Ohio law. That alone does not necessarily invalidate the agreement.

But the process must be honest. The parties must understand the rights being waived. The agreement should reflect intentional planning: not surprise, concealment, or coercion.

The Four-Month Challenge Deadline Is Critical

A surviving spouse who wants to challenge a prenuptial agreement after the other spouse dies must act quickly.

Under Ohio Revised Code Section 2106.22, an antenuptial, postnuptial, or separation agreement involving the decedent is treated as valid unless an action to set it aside is started within four months after the appointment of the estate's executor or administrator: or the agreement's validity is otherwise attacked within that period.

Missing this deadline can forfeit the right to contest the agreement.

Potential grounds for a challenge may include:

• Fraud or concealment.
• Lack of full financial disclosure.
• Duress or coercion.
• Overreaching.
• Lack of a meaningful opportunity to consult counsel.
• Unconscionable terms or circumstances.

The appointment date of the executor or administrator is therefore extremely important. A surviving spouse should not wait for a later distribution or final accounting before seeking legal advice.

Protecting your future requires prompt action.

A Prenup Does Not Automatically Control Every Asset

A common estate-planning mistake is assuming that a prenuptial agreement controls everything a spouse owns. It does not.

Some assets pass outside probate through a beneficiary designation, trust, or form of ownership. These assets may include:

• Life insurance policies.
• Retirement accounts.
• Transfer-on-death accounts.
• Payable-on-death bank accounts.
• Jointly owned property with rights of survivorship.
• Assets held in a revocable or irrevocable trust.
• Certain business interests governed by separate agreements.

These assets generally pass according to their beneficiary designations, trust terms, or ownership documents: not simply according to the will.

For example, a prenup may state that a spouse waives an interest in a life insurance policy. But if the policy still names that spouse as beneficiary, the insurance company may follow the designation unless the estate plan and applicable law provide otherwise. The prenup may create a contractual claim, but it may not automatically change the beneficiary record.

The same problem can occur with retirement accounts. A couple may sign a prenup requiring one spouse to name children from a prior marriage as beneficiaries. If the account form remains unchanged, the intended distribution may not happen as planned.

A will, trust, prenup, and beneficiary designation must tell the same story.

Common Prenuptial and Estate-Planning Pitfalls

Drafting the Prenup but Ignoring Beneficiary Forms

Updating the agreement without updating life insurance, retirement, and financial-account beneficiaries can defeat the intended plan.

Failing to Disclose Assets

A waiver built on incomplete financial information may be vulnerable to challenge. Disclosure should be thorough, documented, and updated as appropriate.

Assuming the Prenup Controls Trust Assets

Trust property follows the trust instrument. The prenup should be reviewed alongside the trust, especially when the trust benefits children from a prior relationship.

Forgetting the Four-Month Deadline

A surviving spouse who believes the agreement is invalid must act within the period established by ORC 2106.22. Delay can close the courthouse door.

Never Reviewing the Plan After Major Life Changes

A business sale, inheritance, new child, divorce, disability, retirement, or significant change in wealth may require revisions. Sometimes the right solution is a postnuptial agreement, updated estate documents, or both.

Takeaway: Plan Clearly. Coordinate Carefully. Act Quickly.

A prenuptial agreement can substantially change how assets are distributed after a spouse dies. It may waive the surviving spouse's elective share, intestate share, support allowance, residence rights, and other statutory benefits.

But enforceability depends on the facts. The agreement should be voluntary. Financial disclosure should be full and fair. The terms and circumstances should withstand scrutiny under Ohio law.

The prenup must also match the will, trust, beneficiary designations, and ownership documents. Otherwise, the estate plan may pull in different directions.
