Wyoming's package uses Morrison v. Hinson-Morrison for contract construction of valid premarital agreements and section 2-5-102 for written waiver of survivor rights and fair disclosure.Morrison v. Hinson-Morrison, 2024 WY 96, ¶¶ 15–23Wyo. Stat. Ann. § 2-5-102
Divorce-related contract interpretation and probate survivor waivers can therefore require separate Wyoming analyses even when they appear in the same document.Morrison v. Hinson-Morrison, 2024 WY 96, ¶¶ 15–23Wyo. Stat. Ann. § 2-5-102
Formation and lifecycle
An agreement, promise, or undertaking made upon consideration of marriage, other than the mutual promise to marry, must be in writing and subscribed by the party to be charged.
Wyo. Stat. Ann. § 1-23-105(a)(iii)An antenuptial agreement may be modified after marriage by further agreement if the governing formal requisites or the agreement's own requirements are satisfied.
Lund v. Lund, 849 P.2d 731, 739–41 (Wyo. 1993)Elective-share, homestead, exempt-property, and family-allowance rights may be waived wholly or partly before or after marriage by a written contract, agreement, or waiver signed after fair disclosure.
Wyo. Stat. Ann. § 2-5-102A premarital agreement is entered in contemplation and consideration of marriage, and the marriage supplies its consideration.
Lund v. Lund, 849 P.2d 731, 739–40 (Wyo. 1993)Wyoming has no enacted UPAA or UPMAA schedule; execution date, the then-current statute of frauds, contract decisions, and any separate probate statute determine the governing regime.
Laird v. Laird, 597 P.2d 463 (Wyo. 1979); Lund; MorrisonWhat the agreement addresses
Valid premarital agreements are contracts governed by ordinary construction rules; clear language controls and a court may not add an omitted commingling provision.
Morrison v. Hinson-Morrison, 2024 WY 96, ¶¶ 15–23Wyoming recognizes antenuptial agreements as valid contracts that define and fix spouses' property rights, with marriage supplying consideration.
Lund v. Lund, 849 P.2d 731, 739–41 (Wyo. 1993)Clear, unambiguous text is construed from the words used, reading the agreement as a whole and each provision in light of the others.
Lund v. Lund, 849 P.2d 731, 739 (Wyo. 1993); Morrison, 2024 WY 96Parents cannot contract away a minor child's right to adequate support even when their agreement is otherwise valid between them.
Combs v. Sherry-Combs, 865 P.2d 50, 55–56 (Wyo. 1993)At divorce the court makes a just and equitable property disposition after statutory factors; valid premarital terms control covered property under Lund and Morrison.
Wyo. Stat. Ann. § 20-2-114Section 20-2-114 authorizes reasonable alimony having regard to the other spouse's ability to pay, subject to any valid contractual limitation and current law.
Wyo. Stat. Ann. § 20-2-114Custody turns on current best interests, while all support orders use current presumptive guidelines subject to statutory deviation and modification rules.
Wyo. Stat. Ann. §§ 20-2-201, 20-2-302 to -307Unless the waiver provides otherwise, a waiver of all rights or equivalent language operates on the listed survivor rights and specified intestate or pre-waiver will benefits.
Wyo. Stat. Ann. § 2-5-102Process evidence
Lund's record addressed whether a later amendment followed full disclosure of the nature, extent, and value of property and required a legally reviewable rationale.
Lund v. Lund, 849 P.2d 731, 737–41 (Wyo. 1993)Wyoming divorce records may require proof that the agreement and any amendment were voluntary, fair, and supported by financial disclosure before enforcement.
Bradley v. Bradley, 2005 WY 107Hypotheticals, not outcomes
These examples show how document facts can intersect with the cited sources. They do not predict a court result.
The parties disagree about whether a clause covers only premarital principal or also later appreciation. Morrison makes the contract's defined terms and overall structure central.Morrison v. Hinson-Morrison, 2024 WY 96, ¶¶ 15–23
How would Wyoming contract-construction principles interpret the clause?
The agreement waives survivor rights but contains limited financial detail. Section 2-5-102 makes writing, signature, and fair disclosure separate probate questions.Wyo. Stat. Ann. § 2-5-102
Does the waiver satisfy Wyoming's current survivor-rights statute?
