Texas Annulment and Prohibited Marriage Laws

In Texas, annulment and prohibited marriage laws are not that different from those of other states. Let's discuss each one in depth more.

What Are The Grounds For Annulment In Texas?

Annulment is the legal process of invalidating a marriage. In Texas, annulment grounds are divided into two categories:

  • Void Texas Annulment Grounds
  • Voidable Texas Annulment Grounds

Void Annulment Grounds

If you are married to a blood relative (father, mother, sister, uncle or aunt), it is grounds for a void annulment. If you are already married to someone else, that's a reason, too. You can't have your wedding cake and eat it, too.

Voidable Annulment Grounds

According to Texas annulment laws, you can file for annulment under the following voidable annulment grounds:

  • Marriage Under the Age of 14;
  • Marriage Under the Age of 18;
  • Under Influence of Alcohol or Drugs;
  • Fraud & Duress;
  • Impotency;
  • Mental Incapacity.

What Types Of Marriages Are Prohibited In Texas?

The Lone Star state prohibits marriage between close relatives (brother and sister, for example) and its same-sex marriage ban is currently under judicial review.
