A Texas marriage annulment is a court order declaring that a marriage was never legally valid, treating the union as if it never existed rather than ending a recognized one the way a divorce does. Texas law sorts invalid marriages into two categories, void and voidable, and which category yours falls into controls whether you even need a court order, what deadline applies, and how property gets divided.
Void Versus Voidable
A void marriage is invalid from the moment it happened. You do not technically need a court order to end one because the law never recognized it, though a decree confirming the marriage is void is useful for clearing up records, dividing property, or resolving questions about children.
A voidable marriage is treated as valid unless and until a spouse goes to court and proves specific grounds. If nobody challenges it, the marriage stands. Voidable marriages come with deadlines, cohabitation restrictions, and procedural requirements that void marriages do not.
When a Texas Marriage Is Automatically Void
Three situations make a marriage void in Texas:
- Close blood relationship. This covers ancestors and descendants, siblings of whole or half blood, aunts or uncles with nieces or nephews, and the same relationships created by adoption.1State of Texas. Texas Family Code 6.201 – Consanguinity
- Bigamy. A marriage entered while either party is still legally married to someone else is void. The later marriage can become valid if the earlier one is dissolved and the couple keeps living together as spouses afterward.2State of Texas. Texas Family Code 6.202 – Marriage During Existence of Prior Marriage
- Underage party. A marriage where either party was under 18 at the ceremony is void unless a court had previously removed the minor’s disabilities of minority.
Because void marriages are legally nonexistent from the start, there is no general deadline for asking a court to declare one void. The bigamy rule adds a specific option for an innocent spouse who did not know about the earlier marriage: you can file a suit to declare the marriage void within 30 days of discovering the prior marriage, or 90 days if you are on active military duty.2State of Texas.

Grounds for a Voidable Marriage
Voidable marriages require a court ruling. Texas law lists several grounds, each with its own requirements and, in some cases, tight filing deadlines.
Underage Spouse Without Parental Consent
If a 16- or 17-year-old married without parental consent or a court order, a parent, guardian, or next friend can petition for annulment. A next friend must file within 90 days of the marriage. The underage spouse can file on their own behalf if they turn 18 during that 90-day window.3State of Texas. Texas Family Code 6.102 – Annulment of Marriage of Person Under Age 18
Intoxication
If you were under the influence of alcohol or drugs at the ceremony and lacked the ability to consent, you can seek annulment. There is no hard filing deadline, but the claim is barred if you voluntarily lived with your spouse after sobering up.4Justia Law. Texas Family Code Chapter 6, Subchapter B – Grounds for Annulment
Permanent Impotency
A marriage can be annulled if either spouse was permanently impotent at the time of the ceremony and the petitioner did not know. You lose the ground if you keep living with your spouse after learning about the condition.5State of Texas. Texas Family Code 6.106 – Impotency
Fraud, Duress, or Force
If your spouse tricked, threatened, or forced you into the marriage, you can petition for annulment. The cohabitation bar applies: you must stop living with your spouse once you learn about the fraud or are free from the duress.6State of Texas. Texas Family Code 6.107 – Fraud, Duress, or Force
Mental Incapacity
Annulment is available if either spouse lacked the mental capacity to understand the marriage ceremony because of a mental disease or defect. The incapacitated person (or their guardian or next friend) can file, and so can the other spouse if they did not know about the condition at the time. Either way, the petitioner must not have voluntarily lived with the other spouse after capacity was regained or the condition discovered.7Texas Public Law. Texas Family Code 6.108 – Mental Incapacity
Concealed Divorce
If your spouse finalized a divorce within 30 days before your wedding and you did not know (and a reasonably careful person would not have known), you can seek annulment. This ground has a firm one-year deadline from the date of the marriage, and the cohabitation bar applies once you discover the hidden divorce.8State of Texas. Texas Family Code 6.109 – Concealed Divorce
Marriage Within 72 Hours of License Issuance
Texas requires a 72-hour waiting period between getting a marriage license and holding the ceremony. If you skipped that period and no court waived it, either spouse can seek annulment. You must file within 30 days of the marriage.9State of Texas. Texas Family Code 6.110 – Marriage Less Than 72 Hours After Issuance of License
The Cohabitation Bar
This is where most voidable annulment claims fall apart. For nearly every ground except underage marriage and the 72-hour rule, Texas requires you to stop living with your spouse as soon as you discover the problem. If you learned your spouse committed fraud but stayed in the home for another six months, the court will treat that as acceptance of the marriage and deny the annulment. Divorce would then be your only option.
The requirement is not just about sharing a roof. Courts look at whether you continued to hold yourselves out as a married couple and maintained a spousal relationship. The petitioner has to prove separation happened once they became aware of the defect.4Justia Law. Texas Family Code Chapter 6, Subchapter B – Grounds for Annulment
Where to File
Annulment jurisdiction in Texas is easier to meet than divorce jurisdiction. A divorce requires six months of state residency and 90 days of county residency. For an annulment, you can file in Texas if either the marriage took place in the state or either spouse is domiciled here.10State of Texas. Texas Family Code 6.306 – Jurisdiction for Suit for Annulment That makes it possible to get into a Texas courtroom for an annulment even if you married in Texas but no longer live there.
Filing and the Hearing
The document that opens the case is an Original Petition to Annul Marriage. Standardized forms are available through the Texas Law Help portal and local district clerk offices. The petition asks for the parties’ full legal names, dates of birth, the date and place of the marriage, and the specific statutory ground you rely on. If children were born during the marriage or you acquired property together, the petition must address those issues too.
You file with the district clerk in the appropriate county and pay the filing fee. Fees vary by county, so check with the local clerk’s office for the exact amount. The clerk assigns a cause number and a court, and your spouse must be formally served with the paperwork. Service can be handled by a constable, sheriff, or private process server, or your spouse can sign a notarized waiver.
After service and any response period, the case goes to a hearing. You appear before a judge and testify under oath about the facts supporting your ground. Bring documentation: medical records for impotency or mental incapacity, evidence of fraud, proof of intoxication, or records showing a concealed divorce. If the judge finds the requirements met, they sign a Final Decree of Annulment.
Property and Children
A common misconception is that because the marriage is treated as if it never existed, there is nothing to divide. That is not how Texas handles it. When a court grants an annulment, it divides the parties’ property the same way it would in a divorce: in a manner the court considers just and right. The judge has broad discretion over assets and debts accumulated during the relationship.
Children born during an annulled marriage are not treated as illegitimate. The court can make custody, visitation, and child support orders as part of the annulment proceeding, just as it would in a divorce. If children or significant property are involved, expect the process to be considerably more complicated than a simple petition and hearing.
Putative Spouse Protections
Texas courts recognize the “putative spouse” doctrine in bigamy situations. If you married someone in good faith without knowing they were already married, you keep community property rights to assets acquired during the relationship, and courts have held that a putative spouse shares equally in community property, the same as a lawful spouse.2State of Texas. Texas Family Code 6.202 – Marriage During Existence of Prior Marriage
Tax, Social Security, and Immigration Effects
An annulment reaches backward, not just forward. Because it declares the marriage was never valid, the IRS requires you to amend your tax returns for every year affected by the annulment that is still within the statute of limitations. You generally have three years from the date you filed the original return (or two years from the date you paid the tax, whichever is later) to file an amended return on Form 1040-X.11Internal Revenue Service. Filing Taxes After Divorce or Separation
On those amended returns, you must change your filing status to single or head of household if you qualify. If you and your former spouse filed jointly and received refunds based on married-filing-jointly rates, the amended returns could produce additional tax owed. Factor this in before finalizing.11Internal Revenue Service. Filing Taxes After Divorce or Separation
If Social Security benefits were terminated because of your marriage, an annulment can restore them. The Social Security Administration treats an annulled marriage as though it never happened, and benefits can be reinstated as of the month the decree was issued. You have to file a timely application with the SSA. If the marriage was declared void rather than voidable, benefits may be reinstated retroactively to the month they ended.12Social Security Administration. Reinstatement of Benefits When Marriage Terminates
If either spouse’s immigration status is based on the marriage, an annulment can create serious complications, because it undercuts the legal foundation for any immigration benefit tied to that marriage. A conditional permanent resident whose marriage is annulled before the two-year mark must file a waiver of the joint filing requirement using Form I-751 and show the marriage was entered into in good faith. USCIS will accept the annulment decree as the basis for converting a joint I-751 filing into a waiver request.13USCIS. Removing Conditions on Permanent Residence Based on Marriage
If the annulment is granted on fraud grounds, the stakes rise sharply. USCIS may treat the fraud finding as evidence that the marriage existed solely to obtain immigration benefits, which can lead to removal proceedings. Anyone in that position should consult an immigration attorney before the annulment is finalized, because the specific ground chosen can drive the immigration outcome.
