You need two witnesses to get married in Montana. Both must be present at the ceremony and sign the marriage certificate along with the two spouses and the officiant. Montana law sets no minimum age and no other qualifications for who can serve, so the choice is almost entirely yours.
Who Can Be a Witness
Any two people willing to attend your ceremony and sign the certificate will satisfy the requirement. Friends, family members, coworkers, or people you meet the day of the wedding all count equally. Couples eloping in Montana often ask hotel staff or bystanders to step in, and that is legally sound.
What matters is presence and signature. The witnesses observe the ceremony, then sign the marriage certificate form alongside you, your spouse, and the officiant. There is no separate witness affidavit, no identification requirement spelled out in the statute, and no residency rule attached to the witness role.
Witnesses for a Written Declaration of Marriage
Montana offers a route to marriage that skips the ceremony entirely: a written declaration of marriage filed with the clerk of the district court. Even on this path, you still need witnesses. At least two must attest to the declaration, which both parties sign and then acknowledge before the clerk of the district court in the county where the signing happens.1Montana State Legislature.

The declaration itself must include both parties’ names, ages, and residences, the fact of marriage, each parent’s name, and a statement that both parties are legally competent to marry. The filing fee matches a standard marriage license at $53.1Montana State Legislature.

The One Path With No Witnesses: Common Law Marriage
Montana is one of the handful of states that still recognizes common law marriage. If you establish one, there is no ceremony, no license, and no witnesses.2Montana State Legislature. Montana Code 40-1-403 – Validity of Common-Law Marriage
Four conditions have to be met: both parties are legally competent to marry, both mutually consent to being married, you live together, and you hold yourselves out to the community as spouses. That last element is where most disputes arise. Evidence that supports it includes using the same last name, filing joint tax returns, referring to each other as spouses, sharing finances, and wearing wedding rings.
A common law marriage carries the same legal weight as a ceremonial one, which means the same property rights, inheritance, and spousal benefits — and the same requirement of a formal divorce to end it. Don’t assume that because no paperwork created the marriage, you can walk away without legal process.
Federal agencies like the Social Security Administration will recognize a Montana common law marriage, but the burden of proving it falls on you. The SSA looks for signed statements from the living spouse and two blood relatives, together with documentation like joint tax returns, shared bank accounts, and sworn statements.3Social Security Administration.

Proxy Marriage: Who Has To Be Present
Montana is one of very few states that permits proxy marriage, in which a stand-in takes the place of an absent spouse. The absent party authorizes a third party in writing to act as proxy, and the officiant must be satisfied that the absent party genuinely cannot attend and has consented to the marriage. If the officiant has doubts, the couple can petition the district court for an order allowing the proxy ceremony.4Montana State Legislature. Montana Code 40-1-301 – Solemnization and Registration
Montana even permits double-proxy marriages, where neither party is physically present and both are represented by stand-ins. To qualify for any proxy marriage, at least one party must either be a Montana resident or an active-duty member of the U.S. armed forces. One party or a legal representative must still appear before the clerk of court and pay the license fee, which is $83 for a double-proxy marriage compared to $53 for a standard license.4Montana State Legislature.

What Your Witnesses Sign and When It Gets Filed
After the ceremony, the officiant completes the marriage certificate and forwards it to the clerk of the district court.4Montana State Legislature. Montana Code 40-1-301 – Solemnization and Registration The signatures belong to the officiant, both spouses, and the two witnesses, and county clerks expect the completed certificate back within 30 days of the ceremony.6Gallatin County, MT.

Follow up with the clerk’s office a few weeks later to confirm the certificate was received and recorded. An unfiled certificate means your marriage may not appear in county records, which creates problems when you need proof for a name change, insurance, or taxes. Once the certificate is on file, you can request certified copies for about $7 each.6Gallatin County, MT. Marriage License
