Domestic Partnership vs. Marriage: When NOT Getting Married Pays Off

Many couples in Washington State don't realize they have options beyond traditional marriage, and often with greater advantages. When clients learn that a domestic partnership could preserve thousands in federal benefits while still providing legal protections, they're often surprised. As family law attorneys in Spokane, we've seen how choosing between marriage and domestic partnership can significantly impact a couple's financial future, especially for those over 62.

What Is a Domestic Partnership in Washington State?

A State Registered Domestic Partnership (SRDP) is a formal legal union registered with the Washington Secretary of State under RCW 26.60. Since 2014, eligibility for domestic partnerships in Washington has had specific requirements that distinguish it from its original purpose.

Current Eligibility Requirements

To register a domestic partnership in Washington State today, couples must meet these criteria:

• At least one partner must be 62 years of age or older.
• Both partners must share a common residence.
• Neither partner can be married or in another domestic partnership.
• Partners cannot be related closer than second cousins.
• Both must be capable of giving legal consent.

This age requirement represents a significant change from pre-2014 laws, when same-sex couples of any age could register domestic partnerships. The automatic conversion of same-sex domestic partnerships to marriages under RCW 26.60 in 2014 transformed the SRDP into a specialized tool primarily for seniors.

Marriage vs. Domestic Partnership: Key Legal Differences

Understanding the distinctions between these two legal statuses is crucial for making an informed decision about your relationship.

State vs. Federal Recognition

The most significant difference lies in federal recognition. While Washington State treats domestic partnerships and marriages equally under state law, the federal government only recognizes marriages as valid. This distinction has far-reaching implications for:

Federal benefits:

• Social Security survivor benefits
• Federal tax filing status
• Immigration sponsorship rights
• Federal employee benefits
• Military spousal benefits

Tax implications: According to IRS Publication 555, registered domestic partners in Washington must file federal taxes as single individuals while splitting community income. This creates a complex tax situation requiring:

• Separate federal tax returns
• Manual calculation of community income splitting
• Potential need for specialized tax preparation assistance

Property Rights and Inheritance

Under Washington State law, both marriages and domestic partnerships create community property rights. However, the practical application differs:

Healthcare and Insurance Benefits

While Washington State law requires insurance companies to treat domestic partners the same as spouses, federal ERISA laws create exceptions. Self-insured employer plans, which cover many employees of large companies, are not required to extend benefits to domestic partners.

Additionally, employer contributions to a domestic partner's health insurance are treated as taxable income at the federal level, unlike employer contributions to spousal coverage, which receive tax-free treatment.

Who Should Consider a Domestic Partnership?

The modern domestic partnership in Washington serves a specific purpose: protecting federal benefits for seniors entering new relationships.

Ideal Candidates for Domestic Partnership

• Seniors receiving survivor benefits: If you're receiving Social Security survivor benefits from a deceased spouse, remarrying before age 60 typically terminates those benefits. A domestic partnership allows you to formalize your new relationship without losing this crucial income.
• Pension recipients: Many private and military pensions cease upon remarriage. A domestic partnership preserves these benefits while providing state-level legal protections.
• Those seeking specific financial advantages: Some couples find the separate federal tax filing status advantageous for their particular financial situation.

When Marriage Is the Better Choice

For couples who don't face the loss of federal benefits, marriage typically offers more comprehensive protection:

• Full federal recognition and benefits
• Simplified tax filing
• Nationwide portability
• Immigration sponsorship rights
• Access to all employer benefits

The Registration Process: Steps and Costs

Understanding how to formalize your relationship is essential for proper planning.

Registering a Domestic Partnership

The process is centralized through the Washington Secretary of State:

1. Download the Declaration form from the Secretary of State website.
2. Complete the form together.
3. Have both signatures notarized.
4. Submit by mail or in person to Olympia.
5. Pay the $50 filing fee.

Processing typically takes 5-10 business days, with expedited service available for an additional fee.

Getting Married in Washington

Marriage licensing occurs at the county level under RCW 26.04:

1. Apply for a license at any County Auditor's office.
2. Provide required identification and information.
3. Pay county fees (ranging from $70-$175, depending on location).
4. Wait the mandatory 3-day period.
5. Have your ceremony within 60 days.
6. File the signed certificate.

Financial Planning Considerations

The choice between marriage and domestic partnership often comes down to financial implications.

Social Security Calculations

According to the Social Security Administration, survivor benefits can range from 71.5% to 100% of the deceased spouse's benefit amount. For someone receiving $2,000 monthly in survivor benefits, choosing domestic partnership over remarriage could preserve $24,000 in annual income.

Tax Complexity Costs

Registered domestic partners face additional tax preparation expenses. The community income splitting requirement often necessitates professional tax assistance, adding $500 to $1,500 annually to tax preparation costs.

Estate Planning Needs

Regardless of your choice, comprehensive estate planning remains essential. Both married couples and domestic partners should create:

• Wills or trusts
• Powers of attorney for healthcare and finances
• Community property agreements (if desired)
• Beneficiary designations on all accounts

Common Misconceptions About Washington Partnerships

Several myths persist about domestic partnerships that can lead to poor decision-making:

1. Myth: Domestic partnerships are easier to dissolve than marriages.

Reality: Dissolution requires the same court process as divorce, including potential spousal support obligations.

2. Myth: Living together creates automatic legal rights.

Reality: Washington does not recognize common-law marriage. Without formal registration, couples have limited legal protections.

3. Myth: City domestic partnership registrations provide the same benefits.

Reality: Local registrations offer minimal benefits compared to state-registered domestic partnerships.

Recent Legislative Changes and Trends

Washington's domestic partnership landscape has undergone significant evolution. The 2022 expansion of the Uniform Parentage Act clarified parental rights for all couples, while recent federal proposals could potentially recognize domestic partnerships for certain benefits.

Statistical data from the Washington Secretary of State shows:

• Approximately 4,890 active domestic partnerships as of 2025
• Over 3,200 partnerships converted to marriages in 2014
• New registrations average 15-20 per month, primarily among seniors

Legal Implications for Property and Debt

Both marriages and domestic partnerships create community property rights in Washington, but understanding the nuances is crucial.

• What's shared: All income earned and property acquired during the relationship become community property under RCW 26.16.
• What's separate: Gifts, inheritances, and pre-relationship property remain individual.
• Critical point: Dissolution requires the same court process as divorce, including potential spousal support under RCW 26.09.
