Nikah in Washington: How to Make Your Islamic Marriage Legal

Planning your nikah in Washington? Most couples want one ceremony that is both religious and legal. In the US that is normally possible: an imam who is authorized to marry couples can lead your nikah and sign your marriage license in the same sitting. Here is how it works in Washington, in plain language.

The short answer

Get a marriage license from a Washington county auditor, wait the three days the law requires, then hold your nikah within 60 days of the license being issued. Washington law names an imam as someone who can solemnize the marriage, and the officiant returns the signed certificate within 30 days. Without a license, a nikah is a religious marriage only.

What makes a marriage legal in Washington

• A marriage license. Both of you apply to the county auditor, usually in the county where you plan to marry, with a sworn application that includes your Social Security numbers and past marital status. You also sign an affidavit that you are at least 18.
• Waiting period. State law says the license cannot be used until three days after you apply. It expires if the marriage is not solemnized within 60 days of the date it was issued. King County words this two ways, so confirm the dates with your auditor.
• An authorized officiant. Washington's statute lists any regularly licensed or ordained minister, or any priest, imam, rabbi or similar official of a religious organization. It sets no separate registration for them.
• Return of the certificate. After the ceremony, the officiant returns the signed certificate to the county auditor within 30 days.

None of this changes the nikah itself. Your imam leads the khutbah, the consent, the mahr, the offer and acceptance and the dua exactly as he otherwise would, and takes care of the civil paperwork at the same time.

Getting a marriage license in Washington

In Washington you apply to the county auditor, and the sworn application asks for names, addresses, ages, Social Security numbers, birthplace, marital status and your residence for the past six months (RCW 26.04.150 and 26.04.160). Some counties need both of you in person. King County, for example, requires both applicants to appear in person to finish the process, and an application by mail must be notarized. Each county sets its own forms, hours and ID rules, so check with your auditor.

King County's page, which shows only a 2026 copyright and no update date, lists a $169 application fee. Fees vary by county, so confirm the current amount with your auditor. No premarital course discount is listed.

Washington requires both people to be at least 18, and a marriage is void if either is under 18 (RCW 26.04.010). You may not marry if either of you has a living spouse or registered domestic partner (unless it is the person you are marrying), or if you are closer in kin than second cousins (RCW 26.04.020). The auditor must issue the license by the third full day after application, and it can be used three days after you apply (RCW 26.04.180). The license expires if the marriage has not been solemnized within 60 days of issue. King County says the three-day wait cannot be waived, and its page words the 60-day count in two different ways, so confirm the dates with your auditor.

Can your imam sign a Washington marriage license?

RCW 26.04.050 lists who can solemnize a marriage in Washington, including judges, court commissioners and certain federal and tribal judges, and any regularly licensed or ordained minister or any priest, imam, rabbi or similar official of a religious organization. It does not require a separate state registration beyond being regularly licensed or ordained. King County's page also says neither applicant may officiate, and that out-of-state clergy may officiate if their organization permits it.

You must state before the officiant and at least two attending witnesses that you take each other as spouses (RCW 26.04.070), and no specific wording is required. Marriages solemnized in a religious organization according to its established ritual are valid if there is no legal impediment (RCW 26.04.120). Clergy are not required to solemnize any marriage. Questions to ask your imam: Will you sign the certificate as officiant? Will you return it to the auditor within 30 days? Who are our two witnesses?

For a civil alternative, a judge or court commissioner can marry you. Ask your county auditor or recorder about courthouse ceremonies.

After the ceremony

The officiant returns the signed marriage certificate to the county auditor within 30 days of the ceremony (RCW 26.04.090). In King County it goes to the Recorder's Office, and the certificate must go back to the county that issued the license even if you marry elsewhere in Washington. Once recorded, you can order certified copies from the county or from the Washington State Department of Health (fees start at $25 per copy; the state may not have the record for up to five months after the wedding). Check each office's page for current fees.

What a religious-only nikah does and does not give you

Religiously, a great deal. You are married in your faith, your contract and mahr are binding between you, and your community recognizes the marriage. Some couples choose this on purpose, for example while one partner is still waiting on immigration or documents.

Legally, an unregistered nikah leaves you unmarried. That usually means no automatic spousal property rights, no automatic inheritance if one of you dies without a will, no spousal health insurance, and trouble with immigration and benefits that ask for a marriage certificate.

Washington's rule on common-law marriage is not spelled out on the official pages we reviewed. King County's Recorder says that under Washington law a wedding without a license will not be recognized as legal or official for civil purposes. For a nikah-only couple, that means a private nikah with no license is a religious marriage that Washington is not expected to treat as a legal one. Do not rely on living together to create a marriage, and ask your auditor or an attorney if your situation is unusual.

Write down the mahr

Agree the mahr before the day and record it in your nikah contract, including how much is given now and how much is deferred. A clear written agreement protects you both. Our mahr calculator can help you settle on an amount, and our step-by-step guide to the nikah ceremony explains each part of the day.
