Texas Annulment and Prohibited Marriage Laws

By FindLaw Staff | Legally reviewed by Nicole Prebeck, Esq. | Last reviewed January 19, 2023

Though it may seem simple, the legal proceedings surrounding marriage actually have strict rules. Each state has its own set of annulment and prohibited marriage laws that prohibit marriages under certain circumstances.

A prohibited marriage is void because the marriage was never lawful. Generally, there's no need to get an annulment or divorce in these cases. Commonly prohibited marriages typically include bigamous marriages, where a person tries to marry more than one spouse, or incestuous marriages, where a person tries to marry a relative.

An annulment, on the other hand, is a way to avoid a marriage that would be otherwise invalid. While both an annulment and a divorce end a marriage, an annulment wipes the slate clean as if there had been no marriage to begin with. However, you usually need to get an annulment within a certain time limit, so it is important to act promptly if you are considering an annulment.

This article provides a brief overview of annulment and prohibited marriages in the state of Texas.
