The first weeks after a death are a short list of practical tasks: certified copies of the death certificate, the burial or cremation arrangements the state allows, and finding out whether the estate needs a court process at all. The What to Do When Someone Dies Checklist puts them in order for your state, split by whether the person left a will, a trust, or nothing.
The other tools answer the questions that checklist raises: how many death certificates to order, whether probate is required, how an executor is appointed and opens an estate account, and what the people receiving property can expect in taxes and timing.
