Questions before comparing outcomes

What counsel should establish first

  1. 01

    Which state's law governs each disputed issue, and is the agreement's choice-of-law clause effective?

  2. 02

    Where did the parties live, sign, marry, own property, and expect to perform the agreement?

  3. 03

    Which current statutes and later cases are absent from either source-catalogued package?

  4. 04

    What execution, counsel, disclosure, waiver, and financial-knowledge evidence can actually be proved?

West Virginia adequate-disclosure alternatives

Adequate disclosure may rest on a reasonably accurate description and good-faith value estimate of property, liabilities, and income, a separate signed waiver, or adequate knowledge or a reasonable basis for it.

West Virginia current pre-Act framework checkpoint

Harton confirms that the 2023 Act does not govern an older agreement and applies surviving Gant procurement principles together with Ware's counsel-dependent burden rule.

  • Harton reversed a facial invalidity ruling on its record; it does not transplant pre-Act rules into Article 1A.
independent counselcourt opinion

Ware v. Ware, 224 W. Va. 599, 687 S.E.2d 382 (2009)

West Virginia pre-Act independent-counsel burden rule

financial disclosurecase reporter

Gross v. Gross, 11 Ohio St. 3d 99 (1984)

Ohio full disclosure or knowledge condition

The proponent must establish full disclosure or the other party's full knowledge and understanding of the nature, value, and extent of the proponent's property when the bargain is disproportionate.

  • General familiarity should not be overstated as knowledge of an omitted material asset or value.
financial disclosurecase reporter

Fletcher v. Fletcher, 68 Ohio St. 3d 464, 628 N.E.2d 1343 (1994)

Ohio disclosure burden for disproportionate bargains

When a party receives disproportionately less than equitable distribution would provide, the proponent bears the burden to show full disclosure or full knowledge of assets.

timingcase reporter

Fletcher v. Fletcher, 68 Ohio St. 3d 464 (1994)

Ohio short-notice pressure presumption

Very short pre-wedding presentation combined with significant postponement hardship, embarrassment, or emotional distress raises a presumption of overreaching or coercion.

Ohio invalid disclosure and timing application

Ohio independent-counsel evidence

Independent advice and the opportunity to obtain it bear on understanding, free assent, disclosure, and overreaching, although counsel is not stated as a separate Gross condition.

  • Counsel participation does not cure fraud, missing disclosure, or coercive timing automatically.
limitationscase reporter

Gross v. Gross, 11 Ohio St. 3d 99 (1984)

Ohio anti-profiteering condition

Premarital terms must not promote or encourage divorce or allow a party to profit by divorce.

Ohio spousal-support enforcement-time review

A divorce-related support provision valid at execution may be reviewed at divorce for unconscionability and reasonableness using the relevant statutory support factors.

propertyofficial guidance

Ohio Rev. Code § 3105.171(A)(6)(a)(v)

Ohio agreement-defined separate property

Property excluded by a valid antenuptial or postnuptial agreement is separate property, subject to tracing and the agreement's actual language.

propertycase reporter

Fletcher v. Fletcher, 68 Ohio St. 3d 464 (1994)

Ohio contract construction after validity

Antenuptial agreements are contracts, so ordinary construction applies to their language after Ohio's special validity safeguards are satisfied.

A qualifying spousal agreement must be written and signed by both spouses, freely entered without fraud, duress, coercion, or overreaching, supported by full disclosure or full knowledge and understanding, and not promote divorce or profiteering.

child supportofficial guidance

Ohio Rev. Code § 3109.04

  • The statute is mandatory child-law context, not an agreement-formation rule.
child supportofficial guidance

Ohio Rev. Code §§ 3119.22–.23

Ohio child-support deviation boundary

A deviation from guideline support requires statutory factors, best-interest findings, and journalized reasons; parents cannot privately eliminate the court's duties.

  • Agreement terms may be evidence but do not substitute for the required calculation and findings.
limitationsofficial guidance

Ohio Rev. Code § 2106.22

Ohio probate challenge deadline

An action or other attack on a decedent's antenuptial or postnuptial agreement generally must occur within four months after appointment of the estate fiduciary.

Ohio common-law and statutory applicability boundary

Ohio has not enacted a UPAA or UPMAA applicability schedule; premarital agreements remain under Gross, while qualifying postmarital instruments require date-specific section 3103.061 analysis.
