When to Apply

Both parties must appear in person when applying for a marriage license. Illinois law requires that the marriage license must be applied for and issued at least one day prior to the marriage ceremony. For example, if you are to be married on a Friday, the license must be applied for and issued no later than Thursday. The one-day waiting period may be waived by petitioning the court for an exception to the law. Once issued, the marriage license is valid for 60 days. If the marriage license is not used during that 60-day period the license becomes void. If the marriage license is not used please notify this office.

Proof of Age

It is necessary to provide proof of age when applying for a marriage license. A state-issued photo I.D., a driver’s license, a valid passport or a certified birth certificate are acceptable proof.

Illinois Age Requirements

Illinois law requires that you must have attained the age of 18 years to be married without parental consent. If you are 16 or 17 years of age both parents must appear in person to sign a parental consent form at the time the parties apply for the marriage license. When one parent cannot be located, law provides for one consenting parent to the marriage to complete an affidavit stating that they have exhausted all means of locating the second parent without success. If this requirement cannot be met due to a parent being deceased, a death certificate, proof of guardianship or court order waiving consent must be presented.

Illinois law prohibits the marriage of anyone under the age of 16. In that case, you may want to seek legal advice. This office cannot provide legal advice.

Persons Who May Not Marry

Certain marriages are prohibited in Illinois. These include marriages entered into prior to the dissolution of an earlier marriage of one of the parties; those between an ancestor and a descendant or between a brother and sister, whether the relationship is by the half or the whole blood or by adoption; and those between an uncle and a niece or between an aunt and a nephew. Generally, marriages between cousins of the first degree are prohibited; however, first cousins may marry if……both parties are 50 years of age or older; or…either party, at the time the couple applies for a marriage license, presents to the county clerk of the county in which the marriage is to take place a certificate signed by a licensed physician stating that the party to the proposed marriage is permanently and irreversibly sterile.

Use of Marriage License

Your marriage license must be obtained in the county where the marriage ceremony will take place. A marriage license is not transferrable for use in any other county or state. If you are unsure in which county your marriage ceremony will be performed, contact this office for assistance.

Marriage by a Judge

If you wish to be married by a judge, you must make your own arrangements at least 1 week prior to the ceremony by calling 815-434-0786. Judges conduct marriage ceremonies on Wednesdays and Fridays. Witnesses are not required.
