Space assignment in Arlington National Cemetery is assigned only when there is need. No site can be reserved and only one grave site will be assigned per family. If a spouse or eligible child dies first, space will be assigned for the spouse's or child's interment, provided the service member agrees in writing to be buried in the same site.
There is no charge for a grave (or columbarium niche) in Arlington National Cemetery, for opening or closing a grave or for a government headstone or marker. Except for active duty service members, all other costs must be borne by the family.
