New Hampshire does not recognize common law marriages during the lifetime of either partner. Under RSA 457:39, the state only acknowledges common law unions posthumously after 3 years of cohabitation when one partner dies. However, New Hampshire will recognize a valid common law marriage established in another state under the Full Faith and Credit Clause, meaning couples who formed such marriages in Colorado, Texas, Iowa, or other recognizing states must obtain a formal divorce in New Hampshire to legally separate. This guide explains how common law divorce in New Hampshire works for out-of-state unions, the property division implications, and what couples cohabiting in New Hampshire need to understand about their legal status.

Does New Hampshire Recognize Common Law Marriage?
New Hampshire does not recognize common law marriages formed within the state during the lifetime of either partner. Under RSA 457:39, the only pathway to common law marriage recognition in New Hampshire is posthumous, requiring that couples cohabited and acknowledged each other as husband and wife for at least 3 years immediately preceding the death of one partner. This narrow exception exists solely for inheritance and survivor benefit purposes, not for divorce.
The practical implications of this law are significant for New Hampshire residents. If you have been living with your partner for 5, 10, or even 20 years in New Hampshire without obtaining a marriage license, you are not legally married under state law. You cannot file for divorce because there is no marriage to dissolve. Instead, you would need to address property separation through contract law, partition actions, or other civil remedies outside the family court system.
New Hampshire requires a formal marriage license under RSA 457:22 for any marriage to be legally valid. The license costs $50, must be obtained from a town or city clerk, and remains valid for 90 days per RSA 457:26. There is no waiting period between obtaining the license and the ceremony, and no blood test is required.
States That Recognize Common Law Marriage in 2026
Understanding which states recognize common law marriage is critical because New Hampshire will honor a valid common law marriage established elsewhere. As of 2026, the following jurisdictions recognize common law marriages formed within their borders:
| State | Key Requirements | Notes |
|---|---|---|
| Colorado | Present agreement, cohabitation, public reputation | No minimum cohabitation period |
| Texas | Agreement, cohabitation, holding out as married OR Declaration of Informal Marriage | Both parties must be 18+ |
| Iowa | Present intent, public declaration, continuous cohabitation, legal capacity | No time limit required |
| Kansas | Present agreement, public representation | Still actively recognizes |
| Montana | Mutual consent, cohabitation | Requires capacity to marry |
| Oklahoma | Mutual agreement, exclusive cohabitation | No specific time requirement |
| Rhode Island | Serious intent, conduct as married | Court determination required |
| Utah | Consenting parties, legal capacity, cohabitation, reputation as married | Court or administrative validation available |
| District of Columbia | Mutual consent to present marital status | Treated as ceremonial marriage equivalent |
If you established a valid common law marriage in any of these jurisdictions and subsequently moved to New Hampshire, you remain legally married. The Full Faith and Credit Clause of the U.S. Constitution requires New Hampshire to recognize your out-of-state common law marriage as valid, even though the state would not permit such a marriage to be formed within its borders.
How to Divorce a Common Law Marriage in New Hampshire
Couples who established a valid common law marriage in another state and now reside in New Hampshire must obtain a formal divorce through the New Hampshire Circuit Court Family Division. The process mirrors that of dissolving a ceremonial marriage, with one critical additional step: proving the common law marriage existed.
Step 1: Establish Proof of the Common Law Marriage
Before filing for divorce, you must be prepared to demonstrate that a valid common law marriage was formed in a state that recognizes such unions. Documentary evidence strengthens your case significantly. Gather joint tax returns filed as married filing jointly, property deeds showing ownership as husband and wife, joint bank account statements, insurance policies naming your spouse as beneficiary, and any written agreements or declarations of marriage.
Witness testimony from family members, friends, employers, or community members who understood you to be married can supplement documentary evidence. If you signed a Declaration of Informal Marriage in Texas, this document serves as definitive proof of your common law marriage status.
Step 2: Meet New Hampshire Residency Requirements
New Hampshire divorce jurisdiction is governed by RSA 458:5, which provides three pathways to establish residency:
First, if both spouses are domiciled in New Hampshire at the time of filing, no minimum residency duration is required and you may file immediately. Second, if you reside in New Hampshire and can personally serve your spouse with divorce papers within the state, no waiting period applies. Third, if you are the sole New Hampshire resident and cannot serve your spouse within the state, you must have been domiciled in New Hampshire for at least 1 year before filing.
Venue is determined by the county where either party resides under RSA 458:9. You will file in the Circuit Court Family Division for that county.
Step 3: File the Divorce Petition
The filing fee for divorce in New Hampshire is $250 without minor children and $282 with minor children as of March 2026. Verify current fees with your local clerk as they are reviewed quarterly. Fee waivers are available for households with income at or below 125% of federal poverty guidelines.
You may file a Joint Petition if both spouses agree to the divorce and its terms, which eliminates the need for formal service. Alternatively, one spouse files as the Petitioner and must serve the other spouse (Respondent) with the divorce papers.
Step 4: Complete Required Programs
If you have minor children, both parents must complete the Child Impact Program within 45 days of filing. This mandatory 4-hour course costs approximately $50 per person and addresses the effects of divorce on children. Family Division Rule 2.10 requires proof of completion before finalization.
Step 5: Negotiate or Litigate Settlement Terms
Uncontested divorces where both parties agree on property division, spousal support, and parenting arrangements typically finalize within 2-3 months. Contested divorces involving disputed issues take 8-18 months, with complex cases sometimes exceeding 24 months.
New Hampshire has no mandatory waiting period, making it one of the most efficient divorce jurisdictions in the country. Once procedural requirements are satisfied and court scheduling permits, your divorce can be finalized.
Property Division for Common Law Marriage Divorce
New Hampshire follows equitable distribution principles under RSA 458:16-a, with a statutory presumption that 50/50 division is equitable. The court may deviate from equal division after considering 15 specific factors. Notably, New Hampshire takes an "all property" approach, meaning courts can divide any asset owned by either spouse regardless of when or how it was acquired.
For common law marriage divorces, this approach has significant implications. Property accumulated during the common law marriage in another state and property acquired after moving to New Hampshire are all potentially divisible. Premarital assets, inherited property, and gifts can also be subject to division, though their separate origin becomes a factor the court considers.
Factors Courts Consider Under RSA 458:16-a
The New Hampshire Supreme Court has clarified that courts must consider all relevant factors when determining equitable distribution. Key factors include the duration of the marriage (including any period of premarital cohabitation per Matter of Munson, 169 N.H. 274), each spouse's economic and non-economic contributions, the age and health of both parties, the expectation of pension or retirement benefits, tax consequences of the proposed division, and the value of any valid prenuptial agreement.
Fault that caused the marriage breakdown may be considered under RSA 458:16-a, II(l) if it resulted in substantial physical or mental pain, economic loss, or both. However, proving fault typically adds $5,000-$10,000 in litigation costs with limited practical impact on the final division.
Premarital Cohabitation Considerations
In Matter of Munson, the New Hampshire Supreme Court held that premarital cohabitation is a factor courts may consider when determining whether to deviate from the 50/50 presumption. For common law marriages, the period before formal recognition (in states that require no minimum duration) may still influence the court's equitable distribution analysis.
The court in In re Crowe, 148 N.H. 218 (2002), noted that short-term marriages may warrant returning property brought to the marriage, while long-term marriages of 10, 20, or 30 years more likely result in equal division of all assets.
Spousal Support Considerations
Alimony in common law marriage divorces follows the same standards as ceremonial marriage divorces. New Hampshire courts consider factors including the length of the marriage, each spouse's earning capacity, contributions to the marriage (including homemaking), health conditions, and the standard of living established during the marriage.
For common law marriages established in other states, courts will typically count the entire duration of the relationship when determining appropriate spousal support, not just time spent in New Hampshire. A couple who lived together as common law spouses in Colorado for 15 years before moving to New Hampshire for 2 years would have the full 17-year relationship considered.
Child Custody and Support in Common Law Divorce
Children born to common law married couples have the same legal status as children born to ceremonially married couples. New Hampshire courts determine custody (parenting rights) and child support using the same standards regardless of how the parents' marriage was formed.
Child support follows New Hampshire's income shares model, calculated using both parents' gross incomes, parenting time allocation, health insurance costs, and childcare expenses. The New Hampshire Child Support Guidelines provide a formula resulting in presumptive support amounts that courts may adjust based on specific circumstances.
Both parents must complete the Child Impact Program before divorce finalization. Courts prioritize the best interests of the child when establishing parenting plans, considering factors including each parent's relationship with the child, stability of proposed living arrangements, and ability to foster the child's relationship with the other parent.
When Common Law Marriage Cannot Be Proven
If you cannot establish that a valid common law marriage existed in a recognizing state, New Hampshire courts will treat your relationship as unmarried cohabitation. This has significant legal consequences:
You cannot file for divorce because no marriage exists to dissolve. Property acquired during cohabitation generally belongs to the person whose name is on the title, unless you can prove otherwise through contract law or unjust enrichment claims. You have no automatic right to spousal support or alimony. Disputes must be resolved through civil court rather than family court.
To protect yourself if you are cohabiting in New Hampshire without formal marriage, consider a cohabitation agreement that addresses property ownership, support obligations, and separation procedures. This written contract can provide legal protection that common law marriage would otherwise offer in other states.
The Posthumous Exception: RSA 457:39 Explained
New Hampshire's unique posthumous recognition provision under RSA 457:39 deserves detailed explanation. This statute provides that persons cohabiting and acknowledging each other as husband and wife, and generally reputed to be such, for the period of 3 years and until the decease of one of them, shall thereafter be deemed to have been legally married.
To qualify for posthumous recognition, three requirements must be met simultaneously for the full 3-year period immediately preceding death. First, continuous cohabitation with no significant breaks or separations during that window. Second, mutual acknowledgment as husband and wife through open declarations, not merely private pet names. Third, general community reputation as a married couple among neighbors, friends, family, and business associates.
This provision primarily benefits surviving partners seeking Social Security survivor benefits, inheritance rights, or wrongful death claims. It does not create a pathway to divorce during the lifetime of both partners.
Proposed 2026 Marriage Liberty Act
New Hampshire legislators have proposed the Marriage Liberty Act, which would create a new type of contract-based marriage agreement enforceable under civil contract law. Under this proposed legislation, partners would define their own terms including duration, renewal provisions, and dissolution procedures without state involvement.
If enacted, this could create an alternative pathway for couples who want legally recognized relationships without traditional marriage licenses. However, such contract marriages might not guarantee federal marriage benefits and would operate differently from both ceremonial and common law marriages. The bill remained pending as of early 2026.
Frequently Asked Questions
Can I get a common law divorce in New Hampshire if my marriage was formed here?
No, you cannot obtain a common law divorce in New Hampshire for a relationship formed within the state. New Hampshire only recognizes common law marriages posthumously under RSA 457:39, requiring 3 years of cohabitation ending with one partner's death. Living together in New Hampshire, regardless of duration, does not create a marriage. You would need to resolve property disputes through civil court rather than family court.
How does New Hampshire handle common law marriages from Texas or Colorado?
New Hampshire recognizes valid common law marriages established in Texas, Colorado, and other recognizing states under the Full Faith and Credit Clause. If you formed a common law marriage meeting all requirements in those states, New Hampshire treats you as legally married. You must obtain a formal divorce through the Circuit Court Family Division, with the same $250-$282 filing fees and procedures as ceremonial marriage divorces.
What proof do I need to show my common law marriage is valid?
Documentary evidence includes joint tax returns filed as married, property deeds showing ownership as spouses, joint bank accounts, insurance beneficiary designations, and signed declarations of marriage. Witness testimony from those who knew you as a married couple supplements written evidence. Texas couples with a Declaration of Informal Marriage have definitive proof. Courts examine whether you met the originating state's specific requirements.
How long does a common law marriage divorce take in New Hampshire?
New Hampshire imposes no mandatory waiting period, making it one of the fastest divorce jurisdictions. Uncontested common law marriage divorces typically finalize within 2-3 months. Contested cases involving disputed property, support, or custody take 8-18 months. Complex cases with high-value assets or contentious parenting disputes can exceed 24 months. The Child Impact Program requirement adds 2-4 weeks for cases with children.
Will living together for 7 years in New Hampshire create a common law marriage?
No, living together for any length of time in New Hampshire will not create a common law marriage. The popular belief that 7 years of cohabitation creates marriage rights is a myth with no basis in New Hampshire law. The state requires a formal marriage license under RSA 457:22. Only the posthumous exception under RSA 457:39 recognizes informal unions, and that requires 3 years of cohabitation ending with death.
How is property divided in a New Hampshire common law divorce?
New Hampshire uses equitable distribution under RSA 458:16-a with a 50/50 presumption. Courts may deviate based on 15 factors including marriage duration, contributions, age, health, and fault. New Hampshire's "all property" approach means any asset owned by either spouse can be divided, regardless of when acquired. Common law marriage duration in another state counts toward total marriage length for property division analysis.
Can I get alimony from a common law marriage divorce in New Hampshire?
Yes, spousal support is available in common law marriage divorces using the same standards as ceremonial marriages. Courts consider relationship length, earning capacity, health, contributions, and established standard of living. The full duration of your common law marriage, including time in the originating state, counts when courts assess appropriate alimony. Average contested divorce costs of $12,300-$44,000 often include alimony litigation expenses.
What happens to children in a common law marriage divorce?
Children from common law marriages have identical legal status to children from ceremonial marriages under New Hampshire law. Courts apply the same best-interests standards for custody determinations and use the income shares model for child support calculations. Both parents must complete the 4-hour Child Impact Program costing approximately $50 per person. Parenting plans address legal decision-making and physical custody arrangements.
Do I need a lawyer for a common law marriage divorce in New Hampshire?
While not legally required, attorney representation is strongly recommended for common law marriage divorces due to the additional complexity of proving the marriage existed. Attorney fees in New Hampshire range from $150-$400 per hour, with average contested divorces costing $12,300-$44,000. Uncontested cases with agreed terms may cost $500-$2,500 total. The investment often pays for itself through better property division outcomes.
Can I file for divorce immediately after moving to New Hampshire?
Yes, if both spouses live in New Hampshire at filing time, no minimum residency period applies under RSA 458:5. You may also file immediately if you can serve your spouse with papers within the state. Only when serving an out-of-state spouse must you wait 1 year after establishing New Hampshire domicile. This flexibility allows recent arrivals to promptly address common law marriage divorces.
Conclusion
Common law divorce in New Hampshire presents unique challenges because the state does not recognize common law marriages formed within its borders during the lifetime of both partners. However, couples who established valid common law marriages in Colorado, Texas, Iowa, Kansas, Montana, Oklahoma, Rhode Island, Utah, or the District of Columbia and subsequently moved to New Hampshire remain legally married and must obtain formal divorces.
The divorce process mirrors ceremonial marriage dissolution, with filing fees of $250-$282, no mandatory waiting period, and equitable distribution of property under RSA 458:16-a. The critical additional requirement is proving the common law marriage was validly formed under the originating state's laws.
For New Hampshire residents cohabiting without formal marriage, understanding that your relationship creates no marriage rights is essential. Protective measures like cohabitation agreements can establish property and support rights that common law marriage would automatically provide in other states. If marriage-equivalent legal protections are important to you, obtaining a formal New Hampshire marriage license for $50 remains the most straightforward path to those rights.
