A prenuptial agreement for a second marriage in Wyoming requires a written document signed by both parties with full financial disclosure under Wyo. Stat. § 20-3-102, and couples entering remarriage should sign at least 30 days before the wedding to avoid coercion claims. Wyoming adopted the Uniform Premarital Agreement Act in 2003, codified at Wyo. Stat. § 20-3-101 through § 20-3-111, providing a clear legal framework for protecting assets accumulated before remarriage, inheritance rights for children from previous relationships, and spousal support obligations. With second marriages facing a 60% divorce rate nationally compared to 40-50% for first marriages, a properly drafted prenup second marriage Wyoming agreement provides essential protection for blended families.

Why a Prenup for a Second Marriage in Wyoming Is Essential
A prenup second marriage Wyoming agreement protects both spouses when entering remarriage because Wyoming uses an all-property approach to divorce, meaning courts can divide any asset owned by either spouse, including premarital property, inheritances, and gifts received during the marriage. Under Wyo. Stat. § 20-2-114, Wyoming courts make property dispositions that appear just and equitable rather than following a strict 50/50 split, which creates uncertainty for individuals bringing significant assets into a second marriage.
The Wyoming Supreme Court established in Lund v. Lund, 849 P.2d 731 (Wyo. 1993) that the purpose of prenuptial agreements is to define and fix respective property rights of spouses before marriage. This landmark decision confirmed that couples can contractually establish their own property division terms rather than leaving decisions to a divorce court.
Second Marriage Statistics That Demand Protection
National statistics demonstrate why protecting assets in a second marriage is critical. Second marriages face a divorce rate of approximately 60% compared to 40-50% for first marriages, and the average duration of a second marriage ending in divorce is 7-10 years. Wyoming specifically has one of the highest divorce rates in the nation at 18.7 divorces per 1,000 married women in 2024, with a divorce-to-marriage ratio of approximately 56%.
Individuals entering a second marriage in Wyoming typically bring substantial accumulated assets from their first marriage, retirement accounts with decades of contributions, real estate with significant equity, business interests developed over 20-30 years, and inheritance expectations that should pass to biological children rather than a new spouse.
Legal Requirements for Wyoming Prenuptial Agreements
Wyoming prenuptial agreements must meet specific statutory requirements under Wyo. Stat. § 20-3-101 through § 20-3-111 to be enforceable. The agreement must be in writing and signed by both parties per Wyo. Stat. § 20-3-102, though notarization is not statutorily required but is strongly recommended to strengthen enforceability and provide evidence of authentic execution.
Voluntariness Requirement
Under Wyo. Stat. § 20-3-106(a)(i), a court will not enforce a premarital agreement if the party against whom enforcement is sought proves the agreement was not executed voluntarily. Wyoming courts treat agreements signed within two weeks of the wedding as potential evidence of coercion, and practitioners universally advise a 30-day buffer between signing and the ceremony to defeat duress claims.
The best practice for ensuring voluntariness is to raise the prenup discussion at least 90 days before the wedding, frame it as mutual financial planning rather than distrust, and have both parties consult with separate attorneys before signing. This timeline demonstrates both parties had adequate opportunity to consider the terms and seek independent advice.
Financial Disclosure Mandate
Wyoming requires full financial disclosure for a prenup to be enforceable. Under the two-prong unconscionability test in Wyo. Stat. § 20-3-106(a)(ii), a challenging party must prove both that the agreement was unconscionable when executed AND that they were not provided fair and reasonable disclosure of the other party's property or financial obligations.
Wyoming attorneys typically satisfy disclosure requirements through sworn financial affidavits attached as exhibits listing every asset, liability, income source, and anticipated inheritance. The disclosure should include bank and investment account statements, real property appraisals, business valuation reports, retirement account statements, life insurance policies, and debt schedules with creditor information.
What a Wyoming Prenup Can and Cannot Include
A valid prenuptial agreement under Wyo. Stat. § 20-3-103 allows couples to pre-decide property rights, support obligations, and estate provisions rather than leaving these determinations to a judge during divorce proceedings. Understanding permissible and prohibited provisions is essential for creating an enforceable remarriage prenuptial agreement.
Permitted Provisions for Second Marriages
Wyoming prenups can legally address the following matters critical to second marriages and blended families:
Separate property designation allows couples to list every asset each partner brings into the marriage with approximate values, ensuring premarital assets remain separate property regardless of how long the marriage lasts. This is particularly important for protecting family ranches, business interests, and accumulated retirement savings.
Marital property definitions establish what becomes joint versus separate property during the marriage, addressing how income earned during the marriage will be treated and whether appreciation on separate property remains separate.
Debt treatment provisions decide whether premarital student loans, credit card debt, or business debt remains the responsibility of the spouse who incurred it, protecting both parties from liability for the other's financial obligations.
Spousal support waivers or limitations are permitted in Wyoming, as confirmed in Seherr-Thoss v. Seherr-Thoss, 141 P.3d 705 (Wyo. 2006). Couples can agree to waive alimony entirely or establish specific formulas for calculating support based on marriage duration.
Life insurance requirements can mandate that each spouse maintain policies benefiting children from previous marriages, ensuring biological children receive inheritance protection regardless of the marriage outcome.
Estate planning provisions coordinate with wills and trusts to ensure children from prior relationships receive intended inheritances rather than having assets pass automatically to a surviving spouse under intestacy laws.
Prohibited Provisions
Under Wyo. Stat. § 20-3-103(b), Wyoming prenuptial agreements cannot adversely affect a child's right to support. Any provision attempting to cap child support below the Wyoming guideline amount is void and unenforceable.
Wyoming prenuptial agreements cannot outline child custody preferences or parenting time arrangements. The state protects children's legal rights and will act in the minors' best interests, ignoring any custody provisions even if included in the agreement. Courts will always determine custody based on the best interests of the child at the time of divorce, not terms negotiated before the marriage.
Protecting Children from Previous Marriages
A prenup second marriage Wyoming agreement provides essential protection for children from prior relationships by establishing inheritance rights, preventing commingling of assets intended for biological children, and ensuring child support obligations from previous marriages remain prioritized.
Inheritance Protection Strategies
Wyoming prenups can ensure children from a previous marriage receive their intended inheritance by designating specific assets as separate property that will pass to biological children rather than a new spouse. This includes requiring each spouse to maintain wills that provide for their respective children, establishing trusts funded during the marriage that benefit children from prior relationships, and waiving rights to elect against the other spouse's will under Wyoming's elective share provisions.
The agreement should address what happens if one spouse dies during the marriage, specifying whether the surviving spouse receives a life estate in the marital home or must vacate, how retirement accounts will be distributed between a surviving spouse and children from prior marriages, and whether life insurance proceeds will benefit children or the surviving spouse.
Protecting Child Support from Previous Marriages
Individuals entering a second marriage often have ongoing child support obligations from their first marriage. A Wyoming prenup can protect the paying spouse's ability to meet these obligations by ensuring marital assets are not depleted in ways that would interfere with court-ordered support payments and by establishing that child support obligations take priority over new marital expenses.
Property Division Without a Prenup in Wyoming
Without a prenuptial agreement, Wyoming courts divide all marital property according to equitable distribution principles under Wyo. Stat. § 20-2-114. The court considers the respective merits of the parties, the condition in which they will be left by the divorce, the party through whom the property was acquired, and the burdens imposed upon the property for the benefit of either party and children.
Wyoming's All-Property Approach Risk
What makes Wyoming particularly risky for second marriages is its all-property approach, where courts can divide any property owned by either spouse, including assets acquired before marriage. This means premarital property, inheritances received during the marriage, and gifts may all be subject to division without a prenup protecting them as separate property.
The Wyoming Supreme Court confirmed in Bailey v. Bailey, 2024 WY 65, that Wyo. Stat. § 20-2-114 does not require an equal division of property, and a just and equitable division is as likely as not to be unequal. This discretion creates significant uncertainty for individuals bringing substantial premarital assets into a remarriage.
| Division Scenario | Without Prenup | With Prenup |
|---|---|---|
| Premarital Home | Subject to equitable division | Designated separate property, protected |
| Retirement Accounts | Court divides based on factors | Pre-marriage balance protected, only marital contributions divisible |
| Inherited Ranch | May be divided based on contributions | Explicitly separate, passes to biological children |
| Business Interests | Valued and divided | Remains with founding spouse |
| Appreciation on Separate Property | Potentially divisible | Specified as separate or marital per agreement |
How to Challenge or Enforce a Wyoming Prenup
Under Wyo. Stat. § 20-3-106, Wyoming courts will refuse to enforce a prenuptial agreement under two circumstances: the agreement was not signed voluntarily, or the agreement was unconscionable when executed and the challenging party was not provided fair disclosure.
Grounds for Challenging Enforcement
The challenging spouse must prove by a preponderance of the evidence either that they did not sign voluntarily or that the agreement was unconscionable when executed AND they were not provided fair and reasonable disclosure. The two-prong unconscionability test means disclosure alone is not a defense; the challenging party must show unconscionability plus a disclosure failure.
Factors Wyoming courts consider when evaluating voluntariness include how close to the wedding the agreement was signed, whether both parties had adequate time to review terms with independent counsel, whether there was any coercion or undue pressure, and whether both parties understood the agreement's terms.
Case Law on Enforcement
In Seherr-Thoss v. Seherr-Thoss, 141 P.3d 705 (Wyo. 2006), the Wyoming Supreme Court affirmed that prenuptial agreements are governed by the same rules of construction applicable to other contracts. When terms are unambiguous, interpretation is a question of law for the court. This case confirmed that spouses can waive alimony in Wyoming prenups and established that clearly drafted agreements will be enforced as written.
The Lund v. Lund, 849 P.2d 731 (Wyo. 1993) decision established that Wyoming prenups are enforceable contracts and that couples who have the foresight to agree on property settlement before marriage will have those agreements honored by courts.
Amendment and Modification Procedures
Under Wyo. Stat. § 20-3-105, amendments to a Wyoming prenuptial agreement must be in writing and signed by both parties, with no new consideration required. This allows couples to modify their agreement as circumstances change during the marriage without needing to provide additional value exchange.
Common reasons for amending a prenup second marriage Wyoming agreement include the birth or adoption of children together, significant changes in either spouse's financial circumstances, acquisition of substantial new assets, changes in applicable law, and approaching retirement or major life transitions.
Postnuptial Agreements as an Alternative
If you are already remarried without a prenuptial agreement, Wyoming recognizes postnuptial agreements as valid contracts between spouses. These agreements function similarly to prenups but are executed after the marriage ceremony. Postnuptial agreements must meet the same requirements of written form, signatures, voluntariness, and full financial disclosure.
However, Wyoming courts may apply additional scrutiny to postnuptial agreements because the parties are already in a confidential relationship as spouses. Full disclosure and independent legal counsel become even more important for postnuptial agreement enforceability.
Cost of a Wyoming Prenuptial Agreement
Attorney fees for drafting a prenuptial agreement in Wyoming typically range from $1,500 to $5,000 per party for straightforward agreements, with complex prenups involving business valuations, multiple properties, or blended family estate planning reaching $5,000 to $15,000 or more per party. Each spouse should have independent counsel, so total costs for a properly drafted agreement often range from $3,000 to $30,000.
Online prenup services range from $150 to $1,500 but may not address Wyoming-specific requirements or the unique complexities of second marriages with children from prior relationships. Given the stakes involved in protecting accumulated assets and children's inheritance rights, professional legal counsel is strongly recommended.
Steps to Create a Wyoming Prenup for a Second Marriage
Creating an enforceable prenup second marriage Wyoming agreement requires systematic attention to timing, disclosure, and legal requirements:
-
Initiate the conversation at least 90 days before the wedding, framing the discussion as mutual financial planning for a blended family rather than distrust
-
Each party compiles complete financial disclosure including all assets, liabilities, income sources, and anticipated inheritances
-
Each party retains separate legal counsel to review the proposed terms and provide independent advice
-
Attorneys exchange disclosure documents and draft the agreement with negotiated terms
-
Both parties review the final draft with their attorneys and request any clarifications
-
Sign the agreement at least 30 days before the wedding ceremony, with notarization recommended
-
Attach complete financial affidavits as exhibits to the executed agreement
-
Store originals securely with each party retaining a copy
Frequently Asked Questions
Is a prenup legally required for a second marriage in Wyoming?
No, Wyoming does not legally require a prenuptial agreement for any marriage, including second marriages. However, without a prenup, Wyoming's all-property equitable distribution approach under Wyo. Stat. § 20-2-114 allows courts to divide any asset owned by either spouse, including premarital property. Given that second marriages face a 60% divorce rate nationally, a prenup provides essential protection for assets accumulated before remarriage.
Can a Wyoming prenup protect my children's inheritance from a previous marriage?
Yes, a Wyoming prenup can protect children's inheritance rights by designating specific assets as separate property that will pass to biological children rather than a new spouse. The agreement can require life insurance beneficiary designations, coordinate with wills and trusts, and prevent the new spouse from claiming elective share rights against your estate. This protection is one of the primary reasons financial advisors recommend prenups for second marriages.
How close to the wedding can I sign a prenup in Wyoming?
Wyoming has no statutory minimum waiting period between signing and marriage, but courts scrutinize agreements signed within two weeks of the wedding as potential evidence of coercion under Wyo. Stat. § 20-3-106(a)(i). Wyoming practitioners universally advise signing at least 30 days before the ceremony to defeat duress claims, with 90 days recommended for initiating discussions.
Does Wyoming require both parties to have separate attorneys for a prenup?
No, Wyoming does not strictly require each party to have independent legal counsel for a prenuptial agreement to be enforceable, as confirmed in Seherr-Thoss v. Seherr-Thoss, 141 P.3d 705 (2006). However, independent counsel significantly strengthens enforceability and ensures both spouses understand the terms they are waiving. For second marriages with significant assets, separate attorneys are strongly recommended.
Can I waive alimony in a Wyoming prenup for a second marriage?
Yes, Wyoming permits spousal support waivers in prenuptial agreements. The Seherr-Thoss case confirmed that alimony can be waived in Wyoming prenups. However, a court might refuse to enforce an alimony waiver if it would leave one spouse destitute or reliant on public assistance, particularly after a long marriage. The waiver should be clearly drafted and both parties should understand its implications.
What financial information must I disclose for a Wyoming prenup?
Wyoming requires fair and reasonable disclosure of property and financial obligations under Wyo. Stat. § 20-3-106(a)(ii). Disclosure should include all bank and investment accounts, real property with appraisals, business interests with valuations, retirement accounts, life insurance policies, debts and liabilities, income from all sources, and anticipated inheritances. Incomplete disclosure creates grounds to challenge the agreement.
Can a Wyoming prenup address child custody for children from a previous marriage?
No, Wyoming prenuptial agreements cannot determine child custody or parenting time arrangements. Under Wyo. Stat. § 20-3-103(b), the state protects children's legal rights and will act in minors' best interests. Even if custody provisions are included in a prenup, courts will ignore them and determine custody based on best interests at the time of divorce.
How much does a prenup cost for a second marriage in Wyoming?
Wyoming prenup attorney fees typically range from $1,500 to $5,000 per party for straightforward agreements, with complex situations involving business valuations and blended family planning reaching $5,000 to $15,000 per party. Since each spouse should have independent counsel, total costs often range from $3,000 to $30,000. This investment protects assets accumulated over decades and children's inheritance rights.
Can I modify a Wyoming prenup after getting married?
Yes, under Wyo. Stat. § 20-3-105, Wyoming prenuptial agreements can be amended after marriage with a written modification signed by both parties. No new consideration is required. Alternatively, couples can execute a postnuptial agreement that modifies or replaces the original prenup, though additional scrutiny may apply to post-marriage agreements.
What makes a Wyoming prenup unenforceable?
A Wyoming court will refuse enforcement under Wyo. Stat. § 20-3-106 if the challenging party proves the agreement was not signed voluntarily (signed under duress, too close to the wedding, without adequate review time) or if the agreement was unconscionable when executed AND the challenging party was not provided fair disclosure. Both unconscionability and disclosure failure must be proven together.
Conclusion
A prenup second marriage Wyoming agreement provides critical protection for individuals entering remarriage with accumulated assets, children from previous relationships, and complex financial circumstances. Wyoming's adoption of the Uniform Premarital Agreement Act at Wyo. Stat. § 20-3-101 through § 20-3-111 provides a clear framework for creating enforceable agreements, but success requires meeting voluntariness and disclosure requirements.
Given Wyoming's all-property approach to equitable distribution and the elevated divorce rate for second marriages, consulting with a Wyoming family law attorney at least 90 days before your wedding ceremony is essential. Proper planning protects both spouses' interests, ensures children from prior relationships receive intended inheritances, and provides certainty that a court-drafted property division might not achieve.
