No vested right of interment gives to any person the right to have the remains of the person interred in any interment space in which the remains of any deceased person having equal or prior vested right of interment have been interred; nor does it give any person the right to have the remains of more than one deceased person interred in a single interment space in violation of the rules and regulations of the cemetery in which the interment space is located.
