Standard requirements for burying a person include a death certificate and a grave site, as of 2015. The exact requirements vary based on the state and the cemetery. If a death is unexplained or caused by a crime, the burial can't occur until after an investigation into the death.
In some states, such as Massachusetts, burial requires a burial permit, which a person obtains using the death certificate. While a casket is a common choice for burials, U.S. law doesn't require one; however, each cemetery has its own rules, so they may require a casket.
While a cemetery is the most common grave site, some states allow burials to occur on private land. The city or county where the land is located must approve the burial.
