Same-sex divorce in New Hampshire follows the same legal framework as any other divorce, but some cases raise additional questions about parentage, property acquired before marriage, prior civil unions, and long-term relationships that began before marriage equality.
New Hampshire has recognized same-sex marriage since 2010, and the same rules governing divorce, property division, alimony, child support, and parental rights and responsibilities apply regardless of the spouses’ genders. Even so, the history of a particular relationship may affect how certain issues are analyzed, especially when the couple lived together, combined finances, or raised children before they were legally married.
Our Manchester LGBTQ+ divorce attorneys help clients understand how New Hampshire law applies to these issues and provide guidance throughout the divorce process.
The Divorce Process for Same-Sex Couples in New Hampshire
Same-sex spouses follow the same New Hampshire divorce process as any other married couple, including the same jurisdiction, filing, financial disclosure, parenting, property, and support rules.
Most divorces are filed on the no-fault ground of irreconcilable differences that have caused the irremediable breakdown of the marriage. New Hampshire also recognizes statutory fault grounds, although proving fault is unnecessary in a no-fault case.
New Hampshire may exercise divorce jurisdiction when both spouses are domiciled in the state, when the filing spouse is domiciled here and the other spouse is personally served in New Hampshire, or when the filing spouse has been domiciled in New Hampshire for at least one year.
After the case begins, the process includes:
- Filing and service: One spouse files the divorce petition and the other receives formal notice, unless the parties proceed through an available joint filing process.
- Temporary issues: The court may enter temporary orders concerning parenting, child support, alimony, use of property, or other issues while the case is pending.
- Financial disclosure and negotiation: The spouses exchange required financial information and work toward agreement on property division, support, and any parenting issues.
- Resolution: An uncontested case may conclude with an agreed final decree, while unresolved issues in a contested case may require additional hearings and ultimately a trial.
The spouses’ genders do not change these procedures, but issues involving parentage, property acquired before the legal marriage, or a prior civil union may require additional analysis during the case.
Pre-Legalization Relationships
New Hampshire courts may consider a couple’s relationship before marriage when resolving certain financial issues, but years of premarital cohabitation do not automatically become part of the legal marriage.
New Hampshire began allowing same-sex couples to marry in 2010. Before that, the state recognized civil unions, and existing New Hampshire civil unions that had not been dissolved or converted were merged into marriages by operation of law on January 1, 2011. In 2015, the U.S. Supreme Court’s decision in Obergefell v. Hodges established a nationwide constitutional right to same-sex marriage and required states to recognize lawful same-sex marriages performed elsewhere.
For couples whose relationships began before they could legally marry, New Hampshire law allows the court to consider premarital cohabitation when dividing property. In In re Munson & Beal, 146 A.3d 153 (2016), a case involving a same-sex couple whose long relationship predated marriage equality, the New Hampshire Supreme Court held that premarital cohabitation may be considered when deciding whether an equal division of marital property would be equitable. This can be significant when spouses shared finances, acquired or improved property, supported one another’s careers, or functioned as an economic household for many years before marrying.
Premarital cohabitation does not, however, automatically extend the legal duration of the marriage for alimony purposes. New Hampshire defines the length of the marriage from the date of marriage to service of the divorce petition. The parties’ longer financial history may still be relevant to the overall financial analysis, including property division and, indirectly, the amount of alimony, but it does not simply convert the entire relationship into years of legal marriage.
Property Division
New Hampshire presumes that an equal division of marital property is equitable, but the court may order an unequal division when the statutory factors make a different result fair.
The marital estate is broadly defined and can include property owned by either spouse, regardless of whose name appears on the title. This can be particularly important for same-sex couples who acquired homes, investment accounts, businesses, or other significant assets during years of cohabitation before marriage was legally available. The fact that an asset was acquired before the legal marriage or titled in only one spouse’s name does not automatically exclude it from consideration in the divorce.
When determining an appropriate property division, the court may consider factors such as the length of the marriage, each spouse’s income and earning capacity, contributions to the marriage, the care of children and the household, the acquisition or preservation of property, and the source of particular assets. New Hampshire law also permits the court to consider other relevant circumstances.
That flexibility is especially significant for couples whose relationship predates marriage equality. In In re Munson & Beal, the New Hampshire Supreme Court held that premarital cohabitation may be considered when deciding whether to depart from the presumption of equal division. A court may therefore consider the parties’ long financial and domestic partnership before marriage, but it does not simply treat those years as additional years of legal marriage.
Child Custody and Parentage in Same-Sex Families
Child custody, parentage, and child support in same-sex divorces are governed by the same New Hampshire standards that apply to other families, but establishing legal parentage can require additional analysis.
New Hampshire law may recognize both spouses as legal parents in several ways:
- Marital presumption: A person may be presumed to be a parent when a child is born to that person’s spouse during the marriage.
- Adoption: A nonbiological parent may establish parentage through adoption, including a second-parent or stepparent adoption where appropriate.
- Parentage order: New Hampshire law also allows parentage to be established by court order, including in certain assisted reproduction cases.
- Other statutory presumptions: New Hampshire law may also presume parentage when a person receives a minor child into their home and openly holds the child out as their own.
When only one spouse is the biological parent and the other did not complete an adoption, the nonbiological spouse is not necessarily without parental rights. Their status may depend on the marital presumption, assisted reproduction statutes, prior court orders, acknowledgment or conduct establishing parentage, and the particular facts of the family. Because parentage can become contested, formalizing it through adoption or a parentage order can provide additional legal certainty.
Once both spouses are recognized as legal parents, child custody issues are decided under New Hampshire’s best-interests standard. The court does not give preference to either parent based on sex, but rather each parent’s relationship with the child, caregiving role, ability to meet the child’s needs, and other statutory factors are considered. Child support is determined under the same New Hampshire child support guidelines that apply in other parenting and divorce cases.
Alimony in a Same-Sex Divorce
New Hampshire applies the same alimony rules to same-sex spouses as to other married couples, but the legal length of the marriage can be especially important when the relationship began years before marriage was available.
For purposes of alimony, New Hampshire generally measures the length of the marriage from the date of marriage to the date the divorce petition is served. That means years of premarital cohabitation do not automatically extend the legal duration of the marriage. Because the presumptive maximum duration of term alimony is tied to the length of the marriage, this distinction can matter for couples who were together for many years before they could legally marry.
Premarital cohabitation may still affect the overall financial analysis. In In re Munson & Beal, the New Hampshire Supreme Court held that a court may consider premarital cohabitation when dividing marital property. Because the property awarded to each spouse is also relevant when determining alimony, a long pre-marriage relationship can indirectly affect the amount of support even though those years do not simply become additional years of marriage.
The court may also consider the spouses’ income, earning capacity, age, health, financial needs, property, contributions to the household, and other statutory factors. In appropriate circumstances, the court may also adjust the ordinary alimony amount or duration limitations when the statutory factors show that justice requires a different result.

Frequently Asked Questions About Same-Sex Divorce in New Hampshire
Does New Hampshire treat same-sex divorce differently from other divorces?
No. Same-sex spouses are subject to the same New Hampshire laws governing divorce, property division, alimony, child support, and parental rights and responsibilities. Additional issues may arise when the relationship predates marriage equality or when parentage was established through adoption, assisted reproduction, or another legal process.
What if we were in a civil union before same-sex marriage was legal?
A New Hampshire civil union that remained in effect was converted into a marriage by operation of law on January 1, 2011. The history of the civil union and any earlier period of cohabitation may also be relevant when the court considers financial issues such as property division.
Can both parents retain custody if only one is the biological parent?
Yes. Biology alone does not determine parental rights in New Hampshire, and a nonbiological spouse may already be a legal parent through the marital presumption, adoption, assisted reproduction laws, or a parentage order. If parentage is disputed, the court may need to determine each person’s legal status before deciding parental rights and responsibilities.
What should I look for in a same-sex divorce attorney?
Look for an attorney who understands both New Hampshire divorce law and the issues that can arise when a relationship predates marriage equality or involves nontraditional paths to parentage. Experience with property division, alimony, parentage, adoption, and parental rights can be particularly important in these cases.
Does a long relationship before marriage affect property division in New Hampshire?
It can. New Hampshire courts may consider premarital cohabitation when deciding whether an equal division of marital property is equitable, including in same-sex relationships that began before marriage was legally available. Those years do not automatically become part of the legal marriage, but the parties’ financial and domestic history may still matter.
