You Can't Barge Into a Funeral Home and Make Demands
The records maintained by a funeral home are private business records--not public records. Funeral homes do not "have" to allow you to see their old records. Some do as a public service and because it generates goodwill in the community. A few even charge. But a funeral home is under no obligation to let you have access to any materials they retained after your relative's funeral--no matter what it cost.
