In Texas, state law does not mandate an autopsy for individuals who die by suicide. However, the situation can vary at the county level. Some counties may require an autopsy if the death is deemed suspicious or if the deceased was under the age of 18. These local regulations are typically in place to ensure proper investigation and to rule out foul play or other contributing factors.
If you are dealing with a specific case, it is advisable to consult the medical examiner's office in the relevant county for the most accurate and current requirements.
