Living together without marriage has become more common over time. In Wyoming, this type of relationship is often called a “live-in relationship” or cohabitation. But it is important to understand that the law treats live-in couples differently from married couples. This article explains the legal rights and limits for people living together in Wyoming without getting married.
Wyoming Does Not Recognize Common Law Marriage
Wyoming law does not accept common law marriage. This means that no matter how long a couple lives together in Wyoming, they are not legally husband and wife unless they have gone through a formal marriage. The courts will not automatically give a live-in couple the rights and protections that come with marriage.
If a couple does marry in another state that recognizes common law marriage and then moves to Wyoming, the state may recognize that marriage. But simply living together in Wyoming does not create legal marriage.
No Automatic Rights for Live-In Couples
Couples living together without marriage do not have the legal benefits that married couples have. For example:
- Property acquired during the relationship is not automatically shared or divided equally if the couple breaks up.
- There is no legal duty for financial support between the partners.
- Rights related to decision-making in medical or legal matters for each other do not apply without specific agreements.
- Unmarried partners do not inherit from each other automatically unless stated in a will.
This means if a live-in relationship ends, the partners must rely on contracts or agreements they have made rather than marital laws.
Agreements Can Protect Live-In Couples
While Wyoming law does not grant automatic rights to live-in couples, the partners can create written agreements called cohabitation agreements. These contracts can clarify how property and expenses are shared and what happens if the relationship ends. Such agreements are useful for protecting each partner’s interests and avoiding legal disputes.
Property Ownership and Finances
If a live-in couple buys property together, the ownership depends on how the title is held and the contributions of each partner. Without marriage, the property is not automatically considered jointly owned. Property disputes can be complex and may require legal action to resolve. Each partner is responsible for their own debts, as there is no legal obligation to cover the other’s liabilities.
No Family Law Protections
Wyoming family laws that protect married couples, such as those about child custody or spousal support, do not apply to live-in partners. If children are involved, custody and support matters will be decided based on the best interests of the child, but the partners themselves have no automatic rights toward each other.
Bottom Line
In Wyoming, live-in relationships do not come with the legal rights and protections of marriage. People living together without vows should understand the limits of their legal rights. To protect themselves, unmarried couples should consider making formal agreements about property, finances, and other important matters.
For complete protection, marriage remains the surest way to secure legal rights as partners under Wyoming law.
