A civil marriage ceremony is a legal union performed by a government official rather than a religious leader, and it comes down to three legal moments: getting a marriage license from the county clerk, exchanging verbal declarations of consent in front of an authorized officiant, and returning the signed license to be recorded. Most ceremonies take under ten minutes. The paperwork around them, and the changes that follow, take longer.
Documents and Eligibility
Both applicants need valid government-issued photo identification: a driver’s license, state ID, or passport. Most jurisdictions also want a certified birth certificate for each person. If either of you was married before, bring a certified copy of the divorce decree or the death certificate that ended that marriage.
The application asks for full legal names, current addresses, and Social Security numbers. Some offices also ask for parents’ full names, including the mother’s maiden name. Check every spelling before you submit. Catching a typo before filing is simple; correcting a recorded certificate afterward can require a court petition.
On age: every state sets the general marriage age at 18, with Nebraska at 19 and Mississippi at 21. Many states still allow minors to marry with parental or judicial consent. As of 2025, fourteen states permit no exceptions, meaning no one under 18 (or 17 in Kentucky) can marry regardless of parental approval or pregnancy.
Premarital blood tests, once routine, are almost entirely gone. A few states ask applicants to review brochures about sexually transmitted infections or inherited conditions, but no test result affects whether you get the license.
Getting the Marriage License
You apply at a county clerk’s office, usually in the county where the ceremony will take place. Both applicants generally appear in person, though some jurisdictions now accept online or mail-in applications. Application fees typically run from $20 to $115 depending on the county. A few places offer a discount if you complete a premarital education course.
Waiting periods vary. Roughly half of states impose none; the rest require anywhere from 24 hours to three business days before the license becomes active. Judges can sometimes waive the wait for hardship. If your timeline is tight, confirm the specific county’s rules well before the date.
Once issued, the license is only valid for a limited window. That window is as short as 30 days in Delaware, Hawaii, and Kentucky, and as long as one year in Arizona, Nebraska, Nevada, and Wyoming. The most common validity period is 60 days. If the license expires before the ceremony, you reapply and pay the fee again.
Who Can Officiate
Authority to legally solemnize a marriage comes from statute and attaches to the officiant’s office or appointment. The most common civil officiants are judges, justices of the peace, and magistrates. Many jurisdictions also authorize court clerks and mayors.
Some courthouses and city clerk offices hold ceremonies on-site for a small fee beyond the license cost. In other locations, the officiant will travel to a venue of your choice. Scheduling varies, so call ahead rather than counting on walk-in service.
One-Day Officiant Designations
Several states let a friend or family member get temporary legal authority to perform your ceremony. In Massachusetts, the Governor can grant a one-day marriage designation to a non-clergy individual; the friend applies through the Secretary of the Commonwealth’s office, uses the designation for that single ceremony, and has no ongoing authority afterward. Other states offer similar processes through their courts or governor’s office.
Self-Solemnization
A small but growing number of states let couples marry themselves with no officiant present. Colorado is the best-known example and permits any couple to self-solemnize. Pennsylvania, the District of Columbia, Illinois, Kansas, Montana, and Wisconsin allow some form of self-uniting marriage, though a few of those limit it to couples with religious objections to using an officiant. The couple signs the license themselves and may or may not need witnesses depending on state law.
What Happens During the Ceremony
A civil ceremony is short. The basic sequence: the officiant opens with a brief statement about the nature of marriage, each person verbally declares consent to marry the other, rings are often exchanged (not legally required), and the officiant pronounces the couple married.
The verbal declarations of consent are the legal heart of the ceremony. Each person must clearly state, in front of the officiant and witnesses, that they are entering the marriage voluntarily. Without those declarations, the ceremony doesn’t satisfy the legal requirements for a binding union. Couples who write their own vows can still meet the requirement; the officiant simply ensures the consent language is in there somewhere.
Most states require one or two witnesses to observe and sign the license. Witnesses generally must be legal adults. After the declarations, the couple, the officiant, and the witnesses all sign. That signed document is the legal record.
Recording the License and Getting Your Certificate
The signed license must go back to the county clerk’s office to be recorded. The officiant typically handles the filing, but confirm it actually happens. Deadlines vary: some counties require filing within 10 days, others allow up to 30. Missing the deadline doesn’t usually invalidate the marriage, but it creates complications when you later need to prove it.
Once the clerk processes the document, they issue a marriage certificate, your official proof of the union. Processing usually takes two to four weeks. You’ll want certified copies for name changes, insurance enrollment, and tax filings. Extra certified copies typically cost between $10 and $35 each. Order at least three or four.
Mistakes happen more often than you’d think: misspelled names, wrong dates, incorrect Social Security numbers. If you catch the error before the license is filed, contact the issuing office immediately; they can usually correct it or reissue before recording. After filing, fixing an error generally requires a court petition explaining the mistake and a court order directing the clerk to amend the record. The specific process varies by jurisdiction.
Updating Your Name and Records After the Ceremony
If either spouse is changing their name, the marriage certificate unlocks every other update. Do these in order, because each step feeds the next.
Start with the Social Security Administration. File Form SS-5 at your local office with your marriage certificate and proof of identity. The name change is free, and the SSA issues a new card with the same number. Visit in person rather than mailing originals if you can. Until the SSA updates your record, other agencies may reject your name change requests because the name on your ID won’t match their database.1Social Security Administration.

Next, the passport. If yours was issued less than one year ago and your name changed within that same year, you can update it for free by mailing Form DS-5504 with the passport, marriage certificate, and a new photo. After the one-year mark, renew through the standard process using Form DS-82 (by mail) or DS-11 (in person), with regular renewal fees. Expedited processing costs an additional $60.2U.S. Department of State. Change or Correct a Passport
The IRS doesn’t require a separate name-change notification if you update your name with the SSA before filing your next return; the new name flows through automatically. If you’ve also changed your address, Form 8822 notifies the IRS so correspondence reaches you. Keeping your SSA records and tax return name in sync prevents refund delays and protects future Social Security benefits.3Internal Revenue Service. Form 8822 – Change of Address
After SSA and passport, visit your state’s motor vehicle office with the new Social Security card and marriage certificate to update your driver’s license. From there, work through bank accounts, employer payroll, insurance policies, and professional licenses. Nearly all will want to see the certified marriage certificate.
What Changes Legally and Financially Right Away
Marriage changes your federal tax status starting the year of the ceremony, even if you marry on December 31. The IRS determines filing status based on whether you were married on the last day of the tax year. Once married, your options are married filing jointly or married filing separately; single is no longer available. For the 2026 tax year, the standard deduction for married couples filing jointly is $32,200.4Internal Revenue Service. Filing Status5Internal Revenue Service.

Marriage also qualifies you for a Special Enrollment Period, giving you 60 days to enroll in or change a Marketplace health insurance plan outside Open Enrollment. If you pick a plan by the last day of the month, coverage can start the first day of the following month. This is the moment to compare whether one spouse should join the other’s employer plan instead.6HealthCare.gov. Getting Health Coverage Outside Open Enrollment
Finally, a longer-term point worth knowing from day one. A surviving spouse can collect Social Security survivor benefits only if the marriage lasted at least nine months before the spouse’s death, with narrow exceptions for accidental death, death in the line of military duty, and a few other circumstances. For divorced spouses, the threshold is ten years of marriage. A spouse caring for the deceased’s child may qualify regardless of how long the marriage lasted.7Social Security Administration.
