Unlawful Carrying of a Weapon Charge in Texas

What if I have a license to carry a handgun? Can I still get arrested for a gun charge in Houston? Absolutely. Become familiar with the new definition of Unlawful Carrying of a Weapon under Texas' newly enacted gun laws in 2021. It may seem like Texas lets anyone and everyone carry a gun whenever and wherever they want, but this is not true. If you are not familiar with Texas gun laws you may find yourself fighting Unlawful Carrying of a Weapon Charges. Under Texas Penal Code Section 46.02, a person commits the offense of "Unlawful Carrying of Weapon" if:

  1. the person intentionally, knowingly, or recklessly carries on or about his or her person a handgun; and

  2. is not: (A) on the person's own premises or premises under the person's control; or (B) inside of or directly en route to a motor vehicle or watercraft that is owned by the person or under the person's control.

Under Texas law, it is illegal to possess a gun or firearm in the following situations:

  • If you are drinking and driving, you may not possess a weapon

  • a prior felony conviction prevents you from lawfully possessing a weapon and will result in a 3rd degree felon in possession of a weapon charge

  • anyone previously convicted of Assault on a Family Member (this is temporary)

  • If you are committing a crime while possessing the firearm

  • Carrying a weapon in your vehicle or on your person that is not concealed (without a CHL)

  • Unlawful carrying of a weapon while in possession of a controlled substance

Felon in Possession of a Weapon Charges

Texas law prevents anyone with a prior felony conviction to possess a weapon or firearm. A felon in possession of a weapon charge in Texas is a 3rd degree felony and carries a minimum sentence of 2 years in prison and a maximum of 10 years. One common defense to a felon in possession of a weapon charge has to do with the term "possession". Title 1, Section 1.07 of the Texas Penal Code defines "possession" as actual, care, custody, control or management of the weapon. This may provide an effective defense to someone charged with Felon in Possession if the person was arrested in a vehicle with other people inside. Depending on where the weapon was found, a good weapons charge defense lawyer may be able to show that his client did not have possession of the weapon. An affidavit from the actual owner of the weapon would be very helpful for this defense.

To ensure you get the best defense possible for your felon in possession of a weapon case, call the experienced Houston Weapons Charge Attorneys at Mercer and Keirnan Criminal Defense Attorneys. Speak directly with Mr. Mercer or Mr. Keirnan by calling 713-236-9700, day or night. You can also request a free case evaluation.
