I have some very weird questions about graveside services

[Historic NY]

2. Its a question for the funeral director...

Some can hold a body for up to 7 days....fees of course. Some cemeteries have receiving vaults where a casketed body can await burial, even a chapel These revert to times when weather prevented burial. So you'd have to ask because there are laws he must follow. Someplaces also have refrigeration. I had to ship my brother home it was 6 days before the service. Usually you are paying for a service that can include all that you ask. The cemetery chosen will charge for opening and closing the grave. I don't know what your state is but check, there are rules and perhaps they have a helpful checklist.
