Step-by-step explanation:
Texas law requires that client files be retained in a funeral establishment for a minimum of three years after the date of the last service provided to the client. This retention period allows for the possible need for families to access these records in the future, and also for regulatory bodies to conduct any necessary inspections or reviews. It is important for funeral establishments to maintain these records in a secure and accessible manner to comply with state regulations and ensure that they can provide necessary documentation when required.
