Which of the following is a legal requirement for cremation in Tennessee?

In Tennessee, the legal requirement for cremation involves obtaining a signed authorization from the next of kin or the person legally authorized to make decisions regarding the disposition of the deceased's remains. This ensures that the wishes of the deceased are respected and that the family has consented to the cremation process. The law emphasizes the importance of familial consent in such sensitive matters, safeguarding the respect and legal standing of family wishes in the disposition of human remains.

The other options do not reflect Tennessee laws on cremation. For example, consent from a lawyer is not a requirement for the process, nor is a public hearing necessary. Similarly, while notification to local authorities might be a procedural aspect of many funeral practices, it does not constitute a specific legal requirement for conducting cremation.
