Providing Strategic Personalized Defense in Harris County
Unauthorized use of a motor vehicle under Texas Penal Code §31.07 is a state jail felony carrying 180 days to 2 years in state jail and fines up to $10,000. The offense is committed when a person intentionally or knowingly operates another person’s vehicle, aircraft, or watercraft without the owner’s effective consent. Unlike auto theft, the state does not need to prove any intent to permanently deprive the owner of the vehicle. The sole question is whether the operation was without consent, and that question is more contested in practice than it sounds.
The central legal issue in every unauthorized use case is what constitutes effective consent and whether it was present. Texas law defines effective consent broadly, and consent does not need to be formal or express. It can be implied by the nature of the relationship between the parties, by a pattern of prior use, or by circumstances that would lead a reasonable person to believe permission existed. Families, household members, employees, and business partners frequently share vehicles under informal arrangements that create genuine disputes about whether any particular use was authorized.
The charge frequently arises in situations that were not straightforward thefts. A family member who took a vehicle without asking, an employee who used a work truck for a personal errand, a person who borrowed a vehicle from someone who had access but not ownership, or a situation where permission was given and later disputed after a falling out are all examples of cases where the consent question is genuinely contested and where a criminal charge may not accurately reflect what actually happened.
At David Smith Law Firm, every unauthorized use case begins with a thorough review of the relationship between the defendant and the vehicle owner, the history of prior vehicle use between the parties, and all communications that bear on what permission was understood to exist. We understand how these cases are built and exactly where the consent element is most open to challenge.
Many unauthorized use cases arise within families and households where the boundaries around vehicle access were never formally established. A spouse, sibling, or adult child who takes a vehicle during an argument or without asking may face this charge in situations where permission would ordinarily have been granted. The history of the relationship and prior patterns of vehicle use are central to establishing that effective consent existed or was reasonably understood to exist.
Employees who use a company vehicle for personal purposes outside the scope of their authorization can face unauthorized use charges. Whether the employee’s use exceeded the permission given, what the employer’s policy actually allowed, and whether the use was a deviation from authorized use or a complete absence of authorization are all relevant legal questions. Employment agreements, vehicle use policies, and the history of how the vehicle was used are all examined carefully.
When a vehicle is borrowed from a person who had access but not legal ownership, the question of whether effective consent from the actual owner existed becomes complicated. The person who lent the vehicle may have had permission to use it but not to lend it to others, creating a situation where the borrower had no knowledge that consent from the owner was absent. Knowledge and good faith are relevant considerations in how these cases are defended.
Unauthorized use of a motor vehicle is sometimes called joyriding because it does not require intent to permanently keep the vehicle. This distinction from auto theft is significant for how the case is charged, but it also means that situations where a vehicle was taken temporarily and returned, or where the defendant had every intention of returning it, may still result in a felony charge. We evaluate whether the specific facts of the situation support any defense that the use was authorized or that consent was reasonably understood to exist.
Consent is not a simple yes or no in most unauthorized use cases. It exists on a spectrum that includes express permission, implied permission, assumed permission, and the reasonable belief that permission existed even if it did not. Texas courts recognize that effective consent can arise from circumstances and relationships, not just formal authorization, and the defense in these cases is built around establishing what the defendant reasonably understood about their authority to operate the vehicle.
Our firm examines every communication between the defendant and the vehicle owner or the person who provided access to the vehicle, the history of how the vehicle was used between the parties before the incident, and any evidence of prior permission that bears on what the defendant believed at the time. In many of these cases, the facts that explain the defendant’s reasonable understanding of the situation are not in the police report. Finding and presenting those facts is the foundation of an effective defense.
