Ohio Annulment and Prohibited Marriage Laws

Regulations relating to marriage, divorce, and annulment are made at the state level. This means that different states have different laws determining when a marriage may be annulled and which types of marriages are prohibited.

Divorce refers to the termination of a valid marriage, while annulment refers to an invalid marriage that is not recognized by law. A party must demonstrate legal grounds (legally-accepted reasons) for an annulment. Each state has laws providing the legal grounds for annulment. Under Ohio annulment and prohibited marriage laws, the grounds for annulment include: if one or both parties are underage, the presence of an undissolved previous marriage, mental incompetence, if consent to be married was obtained through fraud or force, or the marriage was never consummated.

Ohio law prohibits bigamy as well as marriage between individuals who are related (more closely than second cousins). Ohio previously forbade same-sex marriages. In fact, the 2015 Supreme Court Decision that determined that state bans on same-sex marriage and refusal to acknowledge the lawful same-sex marriages of other states were unconstitutional, Obergefell v. Hodges, started as an Ohio case.

The main provisions of Ohio's annulment and prohibited marriage laws are listed in the table below. See FindLaw's Marriage Law section for related articles.
