What should we confirm before paying for caskets, burial containers, and cemetery charges?

Before paying, separate the funeral home's charges from the cemetery's charges and ask for the cemetery's written rules and full price schedule. Confirm any opening and closing fees, perpetual care charges, marker rules, and burial container requirements that apply to the plot. Federal law does not itself require an outer burial container, although an individual cemetery may require one, so the source of any claimed requirement matters.
