Do cemeteries require burial vaults and/or grave boxes?
Most, but not all, cemeteries require you to purchase a burial vault or grave box; also called an Outer Burial Container, for earth burial. In most areas of the country, state or local law does not require that you buy an Outer Burial Container to surround the casket in a grave. However, many cemeteries require that you have one so that the ground will not sink.
