It is in your best interest to make out a final disposition document detailing how you would like your funeral arranged and what to do with your remains. This shouldn’t be put in a will, because often the will isn’t discovered until several weeks after your death. Letting your loved ones know about your wishes also saves them the difficulties of making the decision in what is no doubt a very difficult time for them. If you do not leave a final disposition document, state law will determine who will decide how your remains are handled, usually in this order: spouse, child, parent, next of kin, and then a public administrator.
In your final disposition document, you should detail the name of the funeral home you want to handle your body, the type of casket, whether you want to be embalmed, the details of your funeral ceremony, where you want to be buried or have your remains scattered, and how your remains will be transported.
