People who are in committed, long-term relationships often consider formalizing that bond — not only for the emotional commitment but also for the legal and financial protections marriage can provide. Marriage is the most common route to cementing a lifelong partnership, but another option exists: the domestic partnership.
Below you’ll find a clear comparison between domestic partnerships and marriage, plus practical guidance to help you decide which arrangement might fit your situation best.
What are domestic partnerships
Domestic partnerships first appeared in the 1980s as an alternative to marriage, created largely so same-sex couples could access some legal protections and benefits without a marriage license. Vermont was the first state to introduce domestic partnerships. A key distinction to remember is that domestic partnerships are not recognized at the federal level.
In places that still offer them, domestic partnerships generally share these characteristics:
- Two adults (either same-sex or opposite-sex) who live together and are committed to one another.
- The couple is not married but maintains a relationship similar in many practical ways to marriage.
- Partners are often financially intertwined and may raise children together.
If you want to enter a domestic partnership, you usually do so by registering the relationship — either through an employer that recognizes domestic partnerships or with local or state government offices. The process typically involves completing an application, signing it in front of a witness, and having it notarized, then filing it (often for a fee).
Not every state allows domestic partnerships, so you’ll need to check your state’s rules to learn how to register. A local attorney can help you interpret state-specific laws and complete the filing. Some legal services and websites also offer domestic partnership agreement templates so you can put the arrangement in writing and formalize expectations and responsibilities.
Key differences in marriage vs. domestic partnership rights
Domestic partnerships and marriages are not interchangeable when it comes to legal rights. Marriage generally provides broader legal protections than a domestic partnership, although the two can overlap in important ways. Below are the main similarities and differences to consider.
Benefits of domestic partnership and marriage
Both domestic partnerships and marriages can offer similar practical benefits. For many people, a domestic partnership is appealing because it provides several of the same day-to-day protections as marriage without the formality (or expense) of a wedding.
Common benefits include:
- Access to a partner’s employer-provided health insurance (where an employer’s policy allows it).
- Childcare and custody-related rights, including the ability to adopt or to be recognized as a parent for a child born during the partnership (specifics depend on state law).
- Bereavement and family-care leave protections in some workplaces, allowing time off for a partner’s illness or death.
- Hospital visitation and medical-decision authority in many cases.
These are the kinds of rights domestic partnerships share with marriage — though the scope and enforceability can differ by location and employer.
The legal benefits of each
Although domestic partnerships and marriages overlap in several respects, there are also differences in the legal and financial protections they provide. In many situations marriage offers stronger, more far-reaching benefits than a domestic partnership, but a few perks are unique to domestic partnerships as well.
Benefits available in domestic partnerships
One advantage sometimes cited for domestic partnerships is avoiding the so-called “marriage penalty,” where married couples may — in some tax situations — end up in a higher tax bracket. Because domestic partners file separately (domestic partnerships lack federal recognition), they may avoid that particular pairing of tax brackets.
That said, because domestic partnerships are not recognized federally, partners typically file as single individuals for federal taxes and therefore may miss out on tax breaks and filings options available to married couples — which could offset any savings from avoiding the marriage penalty.
Benefits available only in marriage
Marriage usually confers a longer list of legal and financial rights. Examples include:
- Automatic inheritance rights (spouses often inherit without additional estate-planning paperwork).
- Eligibility for veterans’, Social Security, and many employer retirement benefits based on a spouse’s work history.
- Spousal support and clear mechanisms for dividing assets in divorce.
- The ability for one spouse to sponsor the other for immigration.
- The right to transfer unlimited assets between spouses without immediate tax consequences.
These are benefits many domestic partnerships do not provide, especially because federal recognition is lacking.
Domestic partnership vs. marriage: what’s the financial difference
Financially, domestic partnerships and marriages can look quite different. While both relationship types may allow partners to share employer health coverage, other financial implications diverge:
- Married couples can face a marriage-related change in tax status that, depending on income and deductions, may lead to a higher tax bill (the “marriage penalty”), whereas domestic partners do not experience that specific bracket pairing.
- Spouses typically have stronger inheritance rights; domestic partners may not automatically inherit without a will.
- Married people can claim certain federal benefits — Social Security survivor benefits, many retirement and veterans’ benefits — which domestic partners generally cannot.
- Marriage provides clearer rules for asset transfers and division, including the ability to transfer unlimited assets between spouses without immediate gift tax consequences and structured divorce protections.
The limits of a domestic partnership
Domestic partnerships come with notable limits. First, not all states permit them, so availability depends on where you live. Some people also see domestic partnerships as less socially or legally “serious” than marriage, and that perception can carry stigma.
Protections from a domestic partnership often stop at local or state lines — a partnership registered in one state or city might not be recognized elsewhere. Insurance companies may treat domestic partners differently from spouses, which can affect coverage levels and out-of-pocket costs.
FAQs: pros and cons of domestic partnership
Here are answers to common questions people ask about state-registered domestic partnerships.
Is domestic partnership better than marriage?
It depends on your priorities. If you want many of the practical protections of marriage without a wedding or the formalities of marriage, a domestic partnership can be a useful alternative. But if your priority is full legal and financial protection that’s recognized across states and at the federal level, marriage typically offers more comprehensive benefits.
Can opposite-sex couples get domestic partnerships?
Domestic partnerships were originally created to extend legal protections to same-sex couples before marriage equality, but some jurisdictions now allow opposite-sex couples to register as domestic partners as well. Rules vary widely: some states permit both same-sex and opposite-sex partnerships, while others restrict domestic partnerships to same-sex couples or to older opposite-sex couples (for example, requiring one partner to be 62 or older). Check your state’s laws to know what’s permitted where you live.
Is a domestic partnership the same as marriage?
No. Domestic partnerships can mirror some of the benefits of marriage, but they are not identical. Marriage is recognized nationwide and provides federal benefits that domestic partnerships do not. Domestic partnerships are state- or city-level arrangements and do not grant the same Social Security, federal retirement, or immigration rights that marriage can.

Can you get married after a domestic partnership?
Yes — you can marry your domestic partner. However, there can be legal consequences from any agreements or obligations you signed during the domestic partnership. Case law indicates that those agreements don’t automatically disappear upon marriage, so it may be wise to consult a lawyer to understand how any prior domestic-partnership contracts will be treated.
If your question is whether a person can be in a domestic partnership with one person and be legally married to a different person at the same time, the answer is no: you cannot be legally married and simultaneously enter a domestic partnership with someone else.
Do you have to get a divorce to dissolve a domestic partnership?
Procedures vary by state. Because domestic partnerships are legal relationships, you’ll generally need to take formal action to end them. In some states that means filing a termination statement; in others it requires a process more like divorce or annulment. Check your jurisdiction’s specific rules.
What states allow domestic partnership?
Some states and jurisdictions that recognize domestic partnerships include California, Connecticut, the District of Columbia (D.C.), Nevada, New Jersey, Oregon, Vermont, and Washington. Michigan does not recognize domestic partnerships statewide, though certain cities (for example Ann Arbor, Detroit, East Lansing, and Kalamazoo) permit local registration. Laws differ significantly by place, so confirm the details where you live.
Should I choose domestic partnership or marriage: making the right decision with your partner
Choosing between a domestic partnership and marriage comes down to your and your partner’s needs and priorities.
A domestic partnership can be practical when you’re committed but not ready — financially or emotionally — for a wedding. It can provide important protections such as hospital visitation rights, the ability to make medical decisions for one another, and workplace leave for caregiving. For couples who already live together and share finances, registering as domestic partners can be an accessible way to secure some legal recognition.
If, however, you want the full set of federal and state protections — broader tax and inheritance benefits, access to Social Security and veterans’ benefits, and clearer rules around asset division and immigration sponsorship — marriage is generally the stronger option.
When in doubt, speak with an attorney in your state. They can explain how local laws apply to your circumstances and advise whether domestic partnership or marriage better meets your goals.

Conclusion
A state-registered domestic partnership is a legally recognized relationship that can offer several of the same practical benefits as marriage — things like hospital visitation, certain workplace leave protections, and access to some partner benefits. The American Civil Liberties Union (ACLU) notes that typical domestic partnership requirements include living together, sharing responsibility for joint living expenses, being at least 18 years old, and not being married or in another domestic partnership or civil union.
