What company can you buy life insurance on a son in jail?

This is not a forum in which to discuss or recommend specific insurers. However, a factor that you must consider is the offense of which your son was convicted. The underwriting guidelines of any particular insurer may, for example, preclude issuing a policy to a convicted felon. This is especially true if the felony involved insurance fraud.

Contact a licensed local life insurance agent or broker for specifics.
