Question: can an urn be buried on top of a casket?
Answer: The best and most typical spot for burial of an urn on a gravesite would be at the head or foot of the grave. You would bury the urn directly above the burial vault or casket of your uncle if there was no burial vault. ... The urn was buried near the tombstone (about 20 inches away, so it would be over the vault/coffin).
