I just finished doing this. I spoke with an attorney first (to draft a will) and she asked me if I planned on making pre-paid burial plans. She said it would be a good idea to do that first, so that details could be included in my will. So, I did. In my case, I really have no one to contact when I die, maybe some distant cousins that I don't speak with. They're not part of my will, but I'll mention them in the note I'll be leaving with details regarding my will and that I have a pre-paid cremation plan already paid for and set-up. I, also, had my will filed with the county court where I live. Also, in my case, I plan on sending a letter to my local police department telling them what I did, where I live, what precautions they need to take, that kind of thing, so that they can find me. I'm considering sending a letter, also, to the attorney who drafted my will, telling her that if sh received this letter then it is safe to assume I have died and she can handle my estate, along with the court-appointed executor. This way multiple people will know that I have a pre-paid cremation plan, too. So, it should all work out one way or another. I guess I can't care too much after I'm gone, anyway.
