The people who can legally marry a couple fall into a short list: ordained clergy, judges and certain other civil officials, friends or family who get ordained (often online), notaries public in a handful of states, and, in a few states, the couple themselves. The exact rules depend on the state and often the county where the ceremony takes place, so the authoritative answer always comes from the county clerk issuing your marriage license.
Clergy and Religious Officiants
Every state authorizes religious clergy to perform marriages. That covers ordained ministers, priests, rabbis, imams, and leaders of other recognized religious bodies. The legal test isn’t a specific title or denomination; it’s that the person holds a recognized role within a bona fide religious organization. Courts across the country have generally been reluctant to second-guess which religious groups qualify, which is one reason the category is interpreted broadly.
Most clergy can officiate anywhere in their state without registering county by county. A handful of jurisdictions do require advance registration even for established clergy, so it’s worth a call to the county clerk before the wedding to confirm.
Judges and Other Civil Officials
Civil officials draw their authority from the office they hold rather than from any ordination. Judges at every level of the court system, from local magistrates to federal judges, can typically officiate. Justices of the peace, mayors, and certain court clerks also carry this power in many states.
One wrinkle catches people off guard. A judge’s authority to marry couples sometimes doesn’t extend beyond their own jurisdiction. A municipal court judge in one county may not have automatic authority to officiate in a neighboring county. If you’re asking a judge to officiate outside their normal territory, confirm with the county clerk where the ceremony will take place.
Friends and Family Ordained Online
The most common way a friend or relative becomes your officiant is through online ordination from organizations like the Universal Life Church or American Marriage Ministries. The process takes minutes, often costs nothing, and is legally accepted in the vast majority of states. A few counties in Virginia have historically been resistant to recognizing online ordinations, but broadly, it works nationwide.
“Legally accepted” doesn’t always mean “no extra steps.” Some states require online-ordained ministers to file their credentials with a county clerk’s office or register with a state agency before performing a ceremony. Skipping that step is the single most common way these arrangements go sideways. Your officiant should call the county clerk where the wedding will happen and ask exactly what’s required, ideally several weeks ahead.
Notaries Public
Only a handful of states grant notaries public the authority to officiate weddings. Florida, South Carolina, Maine, Montana, and Tennessee are among those with clear statutory authorization. Nevada also permits it, though notaries there must first obtain a separate certificate of permission from the county clerk. In the remaining states, being a notary gives you no authority to marry anyone.
One-Day Officiant Designations
Some states offer a one-day officiant designation that gives a layperson temporary legal authority to perform a single wedding on a specific date. Massachusetts and Rhode Island are well-known examples. You submit an application and pay a fee, and the authorization expires once the ceremony is complete. For a personal touch without permanent ordination, this is a clean option where available.
Self-Uniting Marriages
In a few states, the couple marries themselves without any officiant. Self-uniting marriages trace their roots to Quaker tradition. Colorado is the most permissive, with no restrictions on who can self-solemnize. Pennsylvania and Washington, D.C. also allow it. Wisconsin permits self-uniting marriages with some conditions, and states like Illinois and Kansas allow it for members of religious groups whose practices don’t require an officiant.
You still need a valid marriage license from the county clerk. You sign it yourselves, your witnesses sign where required, and you return the completed paperwork to the clerk’s office. The marriage is as legally valid as one performed by a judge or member of the clergy.
What the Officiant Legally Has to Do
The ceremony can look however you want it to, but the officiant’s legal job comes down to two moments. First, each person expresses the declaration of intent: a clear, voluntary statement that they take the other as their spouse. Most states don’t mandate specific wording, but both people have to clearly and voluntarily agree to marry in the officiant’s presence. Second, the officiant pronounces the couple married. That pronouncement is the moment solemnization is legally complete.
After the ceremony, the officiant signs the marriage license, makes sure the couple signs, collects any required witness signatures, and returns the completed license to the issuing county clerk’s office. Filing deadlines vary but often fall somewhere between five and thirty days. Missing the deadline doesn’t usually undo the marriage, but it can prevent it from being officially recorded, which causes trouble later when the couple needs a marriage certificate for insurance, taxes, or a name change. If your officiant is a friend doing this for the first time, make sure they understand the timeline and don’t let the signed license sit in a glove compartment for weeks.
Do You Also Need Witnesses
Witness requirements are separate from officiant rules. Roughly half of U.S. states require no witnesses at all. The other half require one or two adults, usually eighteen or older. Iowa requires the witness to show identification, and New Jersey requires a witness who personally knows both members of the couple. Where witnesses are required, their signatures go on the marriage license alongside the couple’s and the officiant’s.
If It Turns Out Your Officiant Wasn’t Authorized
If you discover after the ceremony that your officiant lacked proper authority, your marriage is almost certainly still valid. Most states follow some version of a rule that protects couples who married in good faith believing their officiant was authorized. As long as the couple went through a genuine ceremony and believed they were getting legally married, courts are extremely reluctant to void the marriage over a technicality.
This protection is sometimes formalized through the putative spouse doctrine, which grants full spousal rights to people who reasonably believed they were legally married even when a procedural defect existed. The Social Security Administration, for example, recognizes putative marriages for purposes of survivor benefits and other spousal entitlements, with protection lasting until the person learns the marriage wasn’t technically valid.1Social Security Administration.

That said, “almost certainly still valid” isn’t a guarantee you want to rely on. Fixing an officiant problem after the fact can involve court filings, legal fees, and stress that’s entirely avoidable with a phone call beforehand. The issue tends to surface at the worst possible moments: during a divorce, an insurance claim, or an estate dispute, when the other side has every incentive to argue the marriage was defective.
How to Verify Your Officiant Before the Wedding
The single most reliable step is calling the county clerk’s office where you’re getting your marriage license. That office knows exactly who is authorized to perform marriages in the jurisdiction, what registration is required, and what paperwork the officiant must file afterward. No website, ordination organization, or legal guide is a substitute for this call, because requirements can differ between counties within the same state.
Ask your officiant directly for proof of their authority. For clergy, that means ordination credentials from their religious organization. For online-ordained ministers, it means their ordination certificate plus confirmation they’ve completed any local registration. For civil officials, authority flows from their office, but confirm they can officiate in the specific county where you’re marrying.
Before the wedding day, walk through the post-ceremony logistics with your officiant. Confirm they know they’re responsible for returning the signed license, understand the filing deadline, and have a plan to meet it. The ceremony itself is the easy part. The paperwork is where things go wrong.
