Just oral instructions to your family, or in your will, or pre-paid with a contract?
I wonder how many people plan their own funerals in advance. I'd never known anyone to do that, other than buying a cemetery plot, until my Dad died. We have a son-in-law who is a funeral director/mortician/funeral home manager who handled everything the way Mother wanted. And my Dad had life insurance that not only covered the costs, but Mother decided to pre-pay for her own funeral. They had bought cemetery plots many years ago.
I guess some folks might consider it a bit morbid, but my wife and I have pre-paid and planned our own final party in advance.:laughing: Cremation (we selected the urns for the ashes), simple grave side service, and we selected and paid for the columbarium. It already has our names and dates of birth on it. The cemetery will add the dates of our deaths when the time comes.
In other words, our daughters, grandkids, siblings, etc. will have to do nothing but divide up the property (if we have anything left:laughing

and we have wills for that.
