Common Law Marriage in MN: What Couples Need to Know
Understand how Minnesota handles non-marital relationships, legal rights, and protections for cohabiting couples across key life areas.
Many couples assume that living together long-term grants them the same legal standing as married spouses, a concept often linked to “common law marriage.” This misunderstanding can create significant problems when relationships end, medical decisions arise, or inheritance matters need settling.
For those cohabiting in Minnesota without a formal marriage license, understanding the state’s position is crucial. Confusion about legal status can lead to unexpected and serious consequences.
Minnesota’s Legal Stance
Minnesota does not permit couples to form a marriage simply by living together and presenting themselves as married. The state abolished the creation of new common law marriages within its borders effective April 26, 1941.1Minnesota Legislature. 1941 Minnesota Session Laws Chapter 459 (Abolishing Common Law Marriage) No matter how long a couple lives together in Minnesota or how they portray their relationship, they cannot establish a legally recognized common law marriage under current state law.
To enter a valid marriage in Minnesota, couples must follow specific legal procedures outlined in state statutes. Marriage is defined as a civil contract requiring consent between legally capable individuals.2Minnesota Revisor of Statutes. Minnesota Statutes § 517.01: Marriage a Civil Contract State law mandates obtaining a marriage license and having the marriage solemnized by an authorized person in the presence of two witnesses. The law explicitly states that marriages contracted after April 26, 1941, without meeting these requirements are “null and void.” Living together does not fulfill these legal prerequisites for marriage in Minnesota.
Recognition of Out-of-State Relationships
While Minnesota prohibits forming common law marriages within the state, it generally recognizes marriages legally established elsewhere, including valid common law marriages from states that permit them. If a couple formed a common law marriage according to the laws of a jurisdiction like Colorado or Texas before moving to Minnesota, Minnesota courts will typically acknowledge that marriage.
This recognition stems from the legal principle of comity, where states respect each other’s laws, and is supported by Minnesota statutes validating out-of-state marriages that were lawful where performed. The couple claiming the common law marriage must prove their relationship met all legal requirements in the originating state, typically showing mutual intent to be married, cohabitation there, and presenting themselves publicly as spouses. Minnesota courts will apply the law of the originating state to determine validity. However, state law specifies that even if recognized elsewhere, a marriage involving an individual under 18 is void if either party was a Minnesota resident when the out-of-state marriage occurred.3Minnesota Revisor of Statutes.

Asset and Property Issues
For unmarried couples living together in Minnesota, property ownership rules differ significantly from those for married couples. State law does not automatically grant property rights between unmarried partners based solely on cohabitation. Assets acquired during the marriage of a married couple are typically subject to equitable division upon divorce. In contrast, unmarried partners generally retain individual ownership of assets titled in their name or bought with their separate funds. Property acquired usually belongs to the person holding the legal title.
This distinction is critical if the relationship ends. Without marital property laws, asset disputes can be complicated. For example, if one partner owns a house titled solely in their name, the other partner generally has no automatic claim to its value, regardless of contributions to mortgage payments or improvements. Bank accounts and investments typically remain with the individual owner unless clear evidence of joint ownership exists. Jointly owned assets might be divided, possibly through court action if agreement fails, often based on proven contributions rather than an assumed equal share.
Recognizing potential disputes, Minnesota law governs financial agreements between unmarried cohabitants. State statutes require that any contract concerning property and finances between such couples must be written and signed by both parties to be enforceable.4Minnesota Revisor of Statutes. Minnesota Statutes § 513.075: Cohabitation; Property and Financial Agreements Furthermore, enforcement can typically only be sought after the relationship ends. These laws effectively bar claims based on oral agreements or implied understandings about property arising solely from the cohabitation itself. Courts have interpreted these laws to primarily prevent claims mimicking marital rights without a written agreement, though claims based on independent legal principles (like recovering specific funds contributed to an asset) might sometimes proceed, albeit with difficulty.
Child Custody and Support
The marital status of parents in Minnesota does not determine their rights and responsibilities regarding their children. Child custody and support matters are based on legal parentage. Both parents, married or unmarried, have obligations to support their children and rights concerning custody and parenting time once parentage is established.
For children born to unmarried parents, establishing the father’s legal parentage is essential before courts can issue custody or support orders involving him. The mother initially has sole legal and physical custody. Paternity can be established voluntarily through a signed Recognition of Parentage (ROP) form filed with the state, or through a court action, potentially involving genetic testing if disputed.5Minnesota Department of Human Services. Recognition of Parentage Program
Once paternity is established, either parent can request court orders for custody and parenting time.6Minnesota Judicial Branch. Paternity Help Topic The court’s decision must be based on the “best interests of the child,” considering factors like the child’s needs, parental care history, and the parents’ ability to cooperate.7FindLaw. Minnesota Statutes § 518.17: Custody and Support of Children The court determines both legal custody (decision-making authority) and physical custody (where the child lives).
Establishing parentage also triggers the child support obligation. Both parents are financially responsible. Minnesota uses an “Income Shares” model, considering both parents’ gross incomes to calculate support, aiming to provide the child with resources proportional to what they would have received if the parents lived together. Costs for health insurance and child care are also factored in. Support orders are typically enforced by county agencies until the child turns 18 or finishes high school (up to age 20).
Estate and Inheritance Implications
When someone dies in Minnesota without a valid will (intestate), state laws dictate how their property is distributed. These laws prioritize spouses, children, and other blood relatives. Unmarried partners are not recognized as legal heirs under Minnesota’s intestacy statutes.8Minnesota Judicial Branch. Probate, Wills, and Estates Help Topic Regardless of the relationship’s length or commitment, an unmarried partner has no automatic right to inherit from their deceased partner’s estate if there is no will.
This contrasts sharply with the rights of a legally married spouse, who typically inherits a significant portion, often the entire estate, depending on other surviving relatives. Without legal marriage status, an unmarried partner is excluded. The deceased partner’s individually owned assets will pass to their statutory heirs, potentially bypassing the surviving partner completely.
However, some assets pass outside of wills and intestacy laws. Property owned jointly with rights of survivorship (like real estate or bank accounts titled as “joint tenants”) automatically transfers to the surviving joint owner. Assets with designated beneficiaries, such as life insurance policies and retirement accounts (401(k)s, IRAs), go directly to the named person. An unmarried partner can inherit these types of assets if specifically named as a joint owner or beneficiary.
Given these limitations, deliberate estate planning is crucial for unmarried couples. A valid will is essential. Minnesota law requires a will to be in writing, signed by the testator (the person making the will), and signed by two witnesses. A will allows an individual to explicitly name their unmarried partner as a beneficiary, overriding intestacy rules. Other important documents include a Health Care Directive, appointing an agent (potentially the partner) for health decisions if incapacitated, and a Durable Power of Attorney, authorizing a partner to manage financial affairs.9Minnesota Attorney General’s Office. Health Care Directives Handbook These ensure a partner can act on the other’s behalf during incapacity and help manage affairs before estate distribution.
Cohabitation Agreements
Since Minnesota law offers limited automatic financial rights to unmarried partners, couples may benefit from creating a formal cohabitation agreement. This contract allows partners to define their rights and responsibilities regarding assets and finances during their relationship and if they separate. Without such an agreement, property generally belongs to the title holder, which might not reflect the couple’s intentions.
These agreements allow couples to specify how jointly acquired assets will be divided, who is responsible for debts, and whether any financial support will be provided upon separation. By documenting their intentions clearly in a written contract that meets state requirements, unmarried couples can establish predictability and potentially avoid future disputes over property and finances. It is generally advisable for these agreements to focus strictly on property and financial matters.
When to Seek Legal Guidance
Unmarried couples living together in Minnesota face a legal landscape different from that of married couples, particularly concerning property rights and inheritance. Since the state does not recognize common law marriage formed within its borders after 1941 and requires written agreements for enforcing financial claims between cohabitants upon separation, seeking legal advice can be beneficial.
Consulting with an attorney is advisable when unmarried partners are purchasing significant assets together, such as real estate, or when one partner is making substantial financial contributions to property owned by the other. Legal guidance is also important for drafting enforceable cohabitation agreements that clearly outline financial expectations and property division in case of separation. Furthermore, proper estate planning, including wills, beneficiary designations, health care directives, and powers of attorney, is critical to ensure a partner’s wishes regarding inheritance and end-of-life decisions are legally protected. An attorney can help navigate these complexities and tailor documents to the couple’s specific situation.
