Yes — in states that register domestic partnerships, both partners generally have to share a home, but domestic partners do not have to live together in the strict sense of being under the same roof every night. The legal standard is “common residence,” which means both people treat the same address as their shared home. One partner can travel for work, keep a second place elsewhere, or be away for months, as long as they intend to return. The requirement is there to confirm two people are actually building a shared life, not that they clock the same hours at the same address.
What Common Residence Actually Means
The common residence standard focuses on where both partners live as their shared home. It does not require both names on a lease or deed. If one partner owns or rents the home and the other simply lives there, the requirement is met. The law cares about physical reality, not whose name is on the paperwork.
Having an additional residence is also fine. If one partner keeps an apartment near a workplace in another city but considers the shared home their primary residence, most states treat that as compliant. Reviewing agencies look at the functional picture: where do these two people sleep, keep their belongings, and receive their mail? A partner who maintains a completely separate permanent household with no real connection to the shared address is the scenario the law is designed to screen out.
When One Partner Is Away Temporarily
The common residence requirement does not demand constant physical presence. This is where the intent-to-return principle comes in, and it’s the single most important point for couples worried about time apart.
If one partner leaves the shared home but plans to come back, the partnership remains valid. State statutes that define common residence consistently include this carve-out. Typical qualifying scenarios include:
- Military deployment
- Extended medical treatment at a facility
- Temporary work assignments in another city
- Education-related relocations
The specific reason matters less than the intent. As long as the absent partner treats the shared home as their permanent base, the residency requirement stays intact.
Proving intent to return is straightforward in practice. Keep your name on the lease or mortgage. Maintain your mailing address at the shared home. Leave personal belongings there. Keep contributing to household expenses. These details build the case that you haven’t abandoned the residence. A partner who redirects all mail, moves all possessions, and signs a long-term lease in another city would have a much harder time arguing they still share a common residence with someone back home.
Proving You Share a Residence When You Register
Registering agencies don’t take your word for it. You’ll need documentation showing both partners live at the same address. The easiest proof is government-issued identification displaying matching addresses for both people. If your IDs don’t match yet, secondary documents work: joint utility bills, bank statements, or a shared lease agreement showing both names at the same location.
The registration form itself, often called a Declaration of Domestic Partnership, includes a field for your shared residential address and requires you to affirm under penalty of perjury that you share a home. That legal statement carries real weight. Provide the full street address including apartment or unit numbers. Post office boxes won’t satisfy the requirement, because a box doesn’t prove you physically live somewhere.
Both signatures on the declaration typically need to be notarized. Notary fees generally run from about $2 to $25 per signature, though a handful of states don’t cap the fee at all. Some states also offer a confidential registration option, where the filing becomes a permanent record shielded from public searches unless a court orders disclosure.
Shared Residence Is Only One of Several Requirements
Sharing a home is one box to check. States that register domestic partnerships impose additional eligibility rules, and missing any of them will block your application regardless of how long you’ve lived together.
- Age. Most states require both partners to be at least 18. Some states restrict domestic partnerships to couples where at least one partner is 62 or older, reserving the status for older couples who want legal protections without marriage.
- Marital and partnership status. Neither partner can be married to someone else or currently registered in another domestic partnership that hasn’t been terminated.
- Blood relationship. Partners cannot be related by blood in a way that would prevent them from marrying each other under state law. The exact prohibited degrees vary but generally cover close relatives through at least second cousins.
- Capacity to consent. Both individuals must be mentally capable of understanding and agreeing to the partnership.
These rules track closely with marriage eligibility in most states, which makes sense since domestic partnerships grant many of the same legal protections.
If You Move, Your Shared-Home Status May Not Travel With You
One boundary is worth flagging because couples often assume otherwise. There is no federal law requiring states to recognize a domestic partnership registered in another state. If you register in one state and move to a state without a domestic partnership framework, your legal protections may vanish at the state line, even if you still share a residence in the new state. Employer-sponsored benefits tied to your partnership, inheritance rights, and hospital visitation privileges can all be affected.
Couples who relocate frequently or live near a state border should research whether their destination state recognizes out-of-state partnerships. Some states explicitly extend recognition; many simply have no mechanism for it. The living-together question answers itself once you move; the harder question is whether the state you’ve moved to will treat your partnership as a legal relationship at all.
