| Relationship | Recognized in WA? | Since |
| WA Registered Domestic Partnership (seniors 62+) | Yes | 2007 |
| WA Marriage (any couple) | Yes | 2012 |
| Out-of-state Marriage (same-sex) | Yes | 2012 (R-74) / 2015 (Obergefell) |
| Out-of-state Civil Union / DP | No | — |
Why the Difference?
- Washington's 2009 "Everything But Marriage" law (Ref 71) granted state-level rights to its own DPs — but did not create reciprocity for other states' DPs/CUs.
- Marriage = full faith & credit (constitutional). DP/CU = statutory, state-specific.
- Maine's DP law remains on books (for seniors 62+ and existing registrants) but is not portable to WA.
Practical Impact
- Hospital visitation, medical decisions: Not guaranteed in WA for Maine DP partners.
- Inheritance, property, taxes: WA treats as legal strangers.
- Solution: Marry (anywhere) → recognized everywhere. Or execute WA-specific advance directives, powers of attorney, wills.
Bottom Line
If you have a Maine domestic partnership, it does not transfer to Washington. If you married in Maine, it does. Plan accordingly.
