Classification: Third-degree to first-degree felony
Punishment range: 3rd-degree felony (2–10 years + $10,000) when the other person is 18 or older; 2nd-degree felony when the other person is 17; 1st-degree felony when the other person is 16 or younger
The controlling statute
Texas Penal Code § 25.01 makes bigamy — being married while still legally married to another — a graduated offense with sharply escalating penalties based on the age of the participants. The statute was modernized in 2005 in response to polygamous-sect prosecutions and remains a key tool against forced and underage marriages. Conviction carries severe immigration consequences and may trigger child-protection investigations.

Elements the State must prove
To convict on a Texas § 25.01 charge, the State must prove every element beyond a reasonable doubt:
- Defendant was legally married to one person at the time of the alleged offense
- Defendant purported to marry, lived with, or claimed to be married to another person
- The first marriage was not dissolved or otherwise terminated
- Defendant acted knowingly with respect to the existing marriage
Defense strategies
L and L Law Group, PLLC develops the following defense strategies on every Bigamy case:
- Reasonable belief that prior marriage was dissolved or terminated under § 25.01(a)(2)
- Affirmative defense of reasonable belief that the prior spouse was dead under § 25.01(b)
- Lack of knowledge of the existing marriage's validity (foreign marriage recognition issues)
- Mistake of fact under § 8.02 about marital status
- Religious-marriage carve-out — purely ceremonial marriages not recognized by Texas law may not qualify
- Suppression of investigative material obtained from religious community without warrant
Enhancements & collateral consequences
Section 25.01(e) elevates the offense based on the age of the second purported spouse: third-degree felony by default; 2nd-degree felony if the other person is 17; 1st-degree felony if the other person is 16 or younger. Parallel charges may include sexual assault of a child under § 22.011, indecency with a child under § 21.11, and trafficking under § 20A.02.
