Maine does not recognize common law marriage, meaning couples cannot establish a legally valid marriage through cohabitation and mutual agreement alone, regardless of how long they live together. Under 19-A M.R.S. § 651, all marriages in Maine require a valid license, a ceremony performed by an authorized officiant, and proper registration with the state. However, Maine courts will recognize a valid common law marriage established in another state under the Full Faith and Credit Clause of the U.S. Constitution. If you believe you have a common law marriage from Colorado, Texas, Iowa, Kansas, Montana, Utah, or the District of Columbia, you may need to file for divorce in Maine to legally dissolve that union. This guide explains your options whether you formed a common law marriage elsewhere or are simply ending a long-term cohabiting relationship in Maine.

Does Maine Recognize Common Law Marriage?
Maine has never recognized common law marriage formed within the state, and as of 2026, that legal position remains unchanged. Under Maine law established in 19-A M.R.S. § 651, a valid marriage requires three elements: a marriage license obtained from the town clerk, a ceremony performed by an authorized officiant such as a judge, notary public, or ordained minister, and registration of the certificate with the appropriate municipal office within 7 days. Couples who live together for decades, share finances, raise children, and present themselves publicly as married still do not have a legally recognized marriage in Maine without completing these formal requirements.
The Maine Judicial Branch explicitly states that unmarried partners are considered "unrelated individuals" under Maine law. This classification has significant legal consequences. When an unmarried couple separates, there is no divorce proceeding available. Instead, partners must resolve property disputes through civil litigation, partition actions, or contract enforcement if a cohabitation agreement exists. Maine courts cannot apply marital property division statutes, award spousal support (alimony), or provide the procedural protections that divorce law offers to married couples ending their relationship.
This lack of common law marriage recognition affects approximately 8% of Maine households where adults cohabit without marriage, according to U.S. Census Bureau data. These couples face unique legal vulnerabilities when relationships end, including no automatic property rights, no statutory support obligations, and no inheritance rights without a valid will.
Recognition of Out-of-State Common Law Marriages
Maine courts recognize valid common law marriages established in states where such marriages are legal, pursuant to the Full Faith and Credit Clause of the U.S. Constitution (Article IV, Section 1). Currently, only 8 jurisdictions permit new common law marriages: Colorado, Iowa, Kansas, Montana, New Hampshire (for inheritance purposes only), Texas, Utah, and the District of Columbia. If you established a common law marriage in one of these states before moving to Maine, your marriage remains legally valid, and you must obtain a formal divorce in Maine to dissolve it.
To prove a valid out-of-state common law marriage in Maine divorce proceedings, you must demonstrate that you satisfied all requirements of the state where the marriage was formed. These requirements typically include: present agreement to be married, cohabitation as spouses, public representation as a married couple to family, friends, employers, and the community. Texas law under Family Code §§ 2.401-2.405 additionally requires both parties to be at least 18 years old and permits couples to file a Declaration of Informal Marriage with the County Clerk. Colorado requires community reputation reflecting that others believe you are married, as clarified by the Colorado Supreme Court in January 2021.
Evidence commonly accepted in Maine courts to prove an out-of-state common law marriage includes: joint tax returns filed as married, joint bank accounts and credit cards, shared property deeds and leases listing both parties as spouses, affidavits from family and friends, insurance policies naming a spouse as beneficiary, testimony about cohabitation duration and wedding-like ceremonies, and documentation showing you held yourselves out as husband and wife.
Filing for Divorce in Maine With a Common Law Marriage
If you have a valid common law marriage from another state and wish to divorce in Maine, you must satisfy the jurisdictional requirements under 19-A M.R.S. § 901. Maine courts have jurisdiction if any one of these four conditions applies: you have resided in good faith in Maine for 6 months immediately before filing, you are a Maine resident and the parties were married in Maine, you are a Maine resident and the parties resided in Maine when the grounds for divorce arose, or the defendant currently resides in Maine. For common law marriages established elsewhere, the 6-month residency requirement for the filing spouse is typically the most relevant pathway.
The divorce process for a recognized common law marriage follows the same procedures as any Maine divorce. You must file a Complaint for Divorce (form FM-001) with the District Court in the county where either spouse resides, pay the $120 filing fee plus $5 summons fee, serve your spouse with the complaint and summons, complete the mandatory 60-day waiting period after service, attend mediation if required (cost: $80 per party), and appear for final hearing if the divorce is contested. Total timeline for uncontested divorces ranges from 60-90 days; contested divorces may take 12-18 months.
Property division follows Maine's equitable distribution rules under 19-A M.R.S. § 953. The court divides marital property "in proportions the court considers just" after weighing statutory factors including each spouse's contribution to acquiring the property, economic circumstances at the time of division, duration of the marriage, and the desirability of awarding the family home to the custodial parent. Unlike community property states, Maine does not presume a 50/50 split.
Property Rights for Unmarried Couples in Maine
Unmarried couples who did not establish a valid common law marriage in another state have no access to Maine's divorce courts or equitable distribution laws when their relationships end. Maine's property division statutes under 19-A M.R.S. § 953 apply exclusively to married couples. When unmarried partners separate, each person retains individual ownership of property titled in their name alone, and jointly-owned property must be divided through civil litigation rather than family court proceedings.
The primary legal mechanism for unmarried couples to divide real estate is a partition action. Under Maine's partition statutes, any co-owner of real property can petition the court to divide the property physically (if practical) or force its sale with proceeds distributed according to ownership interests. Partition actions require separate civil filings, involve different procedural rules than divorce, and often result in property being sold at auction rather than transferred between parties. Legal fees for partition actions typically range from $5,000-$15,000, compared to $2,500-$10,000 for uncontested divorces.
For personal property and financial accounts, unmarried partners may pursue claims based on contract law theories such as breach of cohabitation agreement, unjust enrichment (where one partner unfairly benefited at the other's expense), constructive trust (where one partner holds assets that rightfully belong to the other), and resulting trust (where the parties' conduct shows an intent that one partner hold property for the benefit of both). These equitable remedies require extensive evidence and are significantly more difficult to prove than marital property claims.
| Comparison | Married Couples | Unmarried Couples |
|---|---|---|
| Court System | Family/District Court divorce proceedings | Civil Court partition/contract actions |
| Property Division Law | 19-A M.R.S. § 953 equitable distribution | Contract law, unjust enrichment theories |
| Support Obligations | Spousal support/alimony available | No statutory support rights |
| Inheritance Rights | Automatic intestate share (typically 50-100%) | No rights without valid will |
| Average Legal Cost | $2,500-$10,000 (uncontested) | $5,000-$15,000 (partition action) |
| Timeline | 60-90 days (uncontested) | 6-18 months (partition/contract) |
Maine Domestic Partnership as an Alternative
Maine offers domestic partnership registration under 22 M.R.S. § 2710 as a legal status for unmarried couples who want some protections without formal marriage. Domestic partnership provides recognition for purposes of probate, guardianship, conservatorship, inheritance, and protection from abuse proceedings. However, domestic partnership does not create a marriage and does not entitle partners to divorce court jurisdiction, equitable property division, or spousal support when the relationship ends.
To register as domestic partners in Maine, couples must meet specific requirements: both partners must be mentally competent adults, the partners must have been legally domiciled together in Maine for at least 12 consecutive months before filing, neither partner may be married or in another registered domestic partnership, the partners must not be related in a manner that would prohibit marriage under 19-A M.R.S. § 701, and both partners must agree that each is the sole domestic partner of the other. Registration requires filing a Declaration of Domestic Partnership (form VS-70) with the Maine CDC Office of Vital Records.
Terminating a domestic partnership requires filing a notice of termination with the registry. If both partners consent, termination takes effect upon filing. If only one partner files for termination without the other's consent, the terminating partner must serve the other partner with notice, and the termination becomes effective 60 days after service is complete. Unlike divorce, there is no court proceeding to divide property or determine support obligations when a domestic partnership ends. Partners who accumulated shared assets during the relationship must resolve those disputes through civil litigation or private agreement.
Cohabitation Agreements: Essential Protection
A cohabitation agreement is the single most important legal document for unmarried couples in Maine who want clarity about property rights and financial obligations if their relationship ends. Because Maine does not recognize common law marriage, unmarried partners have no automatic legal framework governing their relationship. A properly drafted cohabitation agreement functions as a private contract creating rights and obligations that Maine courts will enforce, providing the structured protection that marriage law offers automatically to married couples.
Effective cohabitation agreements typically address: ownership and division of real estate, including the family home, division of personal property acquired during cohabitation, responsibility for joint debts and credit accounts, whether either partner will provide financial support to the other after separation, rights regarding retirement accounts and investments, disposition of jointly-owned businesses, and arrangements for children's care and support (though courts retain ultimate authority over child-related issues). Maine courts enforce cohabitation agreements under standard contract law principles, requiring that both parties enter the agreement voluntarily with adequate disclosure of assets.
The cost of having an attorney draft a cohabitation agreement in Maine typically ranges from $500-$2,500, depending on the complexity of the couple's financial situation. This investment is minimal compared to the $5,000-$15,000 average cost of litigating a partition action or contract dispute after an unmarried relationship ends. Couples should review and update their cohabitation agreements periodically, particularly after significant financial changes such as purchasing real estate, starting a business, or having children.
Child Custody and Support for Unmarried Parents
Unmarried parents in Maine have the same rights and obligations regarding their children as married parents, regardless of whether they ever established a common law marriage. Both parents have a legal duty to support their children under 19-A M.R.S. § 1551, and Maine courts apply the same custody and child support standards to unmarried parents as to divorcing spouses. The key difference is procedural: unmarried parents file separate parentage and custody actions rather than addressing these issues within a divorce proceeding.
Establishing paternity is essential for unmarried fathers in Maine. If both parents sign a Voluntary Acknowledgment of Paternity at the hospital or later, the father's name appears on the birth certificate and he gains parental rights. Without this acknowledgment, the mother may need to file a paternity action, or the father may need to petition the court for a determination of parentage. Once paternity is established, either parent may file for a parental rights and responsibilities order addressing primary residence, parent-child contact schedules, and decision-making authority.
Child support calculations for unmarried parents follow Maine's child support guidelines under 19-A M.R.S. § 2001, using the same income shares model applied in divorce cases. The guidelines consider both parents' gross incomes, number of children, cost of health insurance and childcare, and the parenting time schedule. Maine's child support enforcement agency can assist with establishing and collecting support orders regardless of whether the parents were ever married.
Proving a Common Law Marriage From Another State
If you believe you have a valid common law marriage from another state and need to file for divorce in Maine, gathering comprehensive evidence before filing is critical. Maine courts require clear and convincing evidence that all elements of the other state's common law marriage requirements were satisfied during the time you resided there. The burden of proof falls on the party asserting the marriage exists, and failure to meet this burden means the court will treat you as unmarried partners with no divorce jurisdiction.
Documentary evidence carries significant weight in proving common law marriage. Useful documents include joint federal and state tax returns filed as "married filing jointly" or "married filing separately," health and life insurance policies listing a spouse as beneficiary, joint bank account and credit card statements, real estate deeds showing ownership as "husband and wife" or "married couple," lease agreements and utility bills in both names, correspondence or cards addressed to you as a married couple, and affidavits from family members, friends, or employers attesting to your representation as married. If you filed a Declaration of Informal Marriage in Texas, this document serves as conclusive proof of marriage.
Testimony about your relationship is also important. Be prepared to describe when you agreed to be married, how you represented yourselves to others as spouses, the duration and nature of your cohabitation, whether you wore wedding rings or had a ceremony, how you referred to each other ("my husband/wife" versus "my boyfriend/girlfriend/partner"), and specific instances where third parties treated you as a married couple. Inconsistent statements or evidence that you sometimes represented yourselves as unmarried can undermine your claim.
Steps to Take When Separating From an Unmarried Partner
If you are separating from a long-term partner in Maine and do not have a valid common law marriage from another state, following a structured approach protects your legal interests and minimizes conflict. Because Maine provides no divorce framework for unmarried couples, you must navigate property division, support issues, and custody matters through a combination of negotiation, mediation, and potentially civil litigation.
Step 1: Gather and organize financial documentation including bank account statements (individual and joint), credit card statements, mortgage documents and property deeds, vehicle titles, retirement account statements, tax returns from recent years, and documentation of debts. This information establishes what assets and liabilities exist and provides the foundation for negotiation.
Step 2: Determine ownership of property. In Maine, property is generally owned by the person whose name is on the title or account. Jointly-titled property is presumed to be owned in equal shares unless evidence shows otherwise. Review deeds, titles, and account ownership to understand your legal position before negotiating.
Step 3: If you have children together, address custody and support through the appropriate legal channels. Either parent can file a petition for allocation of parental rights and responsibilities in District Court. Filing fee is $120. Consider mediation first, as court-ordered mediation costs $80 per party and voluntary mediation may cost $150-$300 per hour.
Step 4: For jointly-owned real estate, determine whether one partner can buy out the other's interest, whether you will sell the property and divide proceeds, or whether you need to file a partition action. A real estate attorney can draft a buyout agreement for approximately $500-$1,500, significantly less than litigation costs.
Step 5: Close joint accounts and establish individual accounts. Notify creditors of the separation to protect yourself from liability for your former partner's future debts on joint credit cards.
Frequently Asked Questions
Can I get divorced in Maine if I was never formally married?
No, Maine courts cannot grant a divorce to couples who were never legally married. If you cohabited in Maine without a marriage license and ceremony, you are not married under Maine law regardless of the relationship duration. You must resolve property disputes through civil court partition actions or contract claims, not divorce proceedings. The only exception is if you established a valid common law marriage in another state before moving to Maine.
How do I prove my Texas common law marriage is valid in Maine?
To prove a Texas common law marriage in Maine court, you need evidence satisfying Texas Family Code §§ 2.401-2.405 requirements: agreement to be married, cohabitation in Texas, and representation to others as married. If you filed a Declaration of Informal Marriage with a Texas County Clerk, that document provides conclusive proof. Otherwise, gather joint tax returns, property documents showing "husband and wife," insurance beneficiary designations, and affidavits from people who knew you as a married couple.
Does Maine have palimony for unmarried partners?
Maine does not have a statutory palimony law guaranteeing financial support to unmarried partners after separation. Spousal support under 19-A M.R.S. § 951-A applies only to married couples. Unmarried partners may pursue contract-based claims if they have a written cohabitation agreement promising support, or possibly oral contract claims with sufficient evidence, but these require civil litigation and are difficult to prove without documentation.
What is the filing fee for divorce in Maine?
The filing fee for divorce in Maine is $120 as of March 2026. Additional costs include a $5 summons fee and $25-$50 for sheriff service of the complaint on your spouse. Court-ordered mediation costs $80 per party ($160 total). Low-income filers can request fee waivers using form CV-067 with financial affidavit CV-191. Automatic approval is granted for recipients of TANF, SSI, or general assistance; others must have household income at or below 200% of federal poverty guidelines ($31,920 for single person in 2026).
How long do I have to live in Maine to file for divorce?
Under 19-A M.R.S. § 901, you must satisfy one of four residency conditions: reside in Maine for 6 months immediately before filing, be a Maine resident who was married in Maine, be a Maine resident when the grounds for divorce arose while living in Maine, or file against a spouse who currently resides in Maine. The 6-month residency requirement is most commonly used and requires "good faith" residence, meaning actual physical presence with intent to remain.
What happens to property when unmarried partners separate in Maine?
When unmarried partners separate in Maine, each person retains property titled in their individual name. Jointly-owned property must be divided through negotiation, mediation, or civil litigation (partition action). Maine's equitable distribution laws under 19-A M.R.S. § 953 do not apply because you are not married. The court cannot transfer one partner's separate property to the other absent a valid contract. Average cost for partition litigation is $5,000-$15,000.
Is domestic partnership the same as common law marriage in Maine?
No, domestic partnership under 22 M.R.S. § 2710 is not marriage. It provides limited legal recognition for probate, guardianship, and protection from abuse purposes, but does not create marital rights. Domestic partners cannot file for divorce, seek equitable property division, or claim spousal support. Terminating a domestic partnership requires filing a notice with the registry, not a court proceeding. You must cohabit in Maine for 12 months before registering.
Can I inherit from my unmarried partner if they die without a will?
No, unmarried partners have no automatic inheritance rights under Maine's intestacy laws. If your partner dies without a valid will, their estate passes to blood relatives (children, parents, siblings) under 18-C M.R.S. § 2-102. Registered domestic partners have some inheritance protections, but cohabiting couples without domestic partnership registration receive nothing automatically. Creating a will or trust is essential for unmarried partners who want their partner to inherit.
What states allow common law marriage that Maine will recognize?
Maine recognizes valid common law marriages from states that currently permit them: Colorado, Iowa, Kansas, Montana, Texas, Utah, and the District of Columbia. New Hampshire recognizes common law marriage only for inheritance purposes. Several states (Alabama, Georgia, Idaho, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Carolina) grandfathered common law marriages formed before they abolished the practice. If your common law marriage was valid where formed, Maine courts will recognize it under the Full Faith and Credit Clause.
How is child support calculated for unmarried parents in Maine?
Child support for unmarried parents follows the same guidelines as divorced parents under 19-A M.R.S. § 2001. Maine uses an income shares model considering both parents' gross incomes, number of children, health insurance costs, childcare expenses, and parenting time percentage. The guidelines calculate a basic support obligation that is divided between parents proportionally to their incomes. Either parent can file for a child support order once paternity is established.
Should I get a cohabitation agreement in Maine?
Yes, a cohabitation agreement is highly recommended for unmarried couples in Maine, especially those who own property together, share significant financial assets, or plan long-term cohabitation. Because Maine does not recognize common law marriage, this agreement is your only mechanism to define property rights, support obligations, and division procedures if the relationship ends. Cost to have an attorney draft a comprehensive agreement is $500-$2,500, far less than the $5,000-$15,000 average cost of litigating property disputes after separation.
