Before business and legal issues of the estate can be addressed, you will need certified copies of the death certificate as most agencies will not accept photocopies. Death Certificates can be obtained by your Funeral Director or directly from your local Registrar of Vital Statistics. It's a good idea to order a few more than you think you'll need.
You may need to obtain a certified copy of the death certificate without a cause of death. These are needed to transfer the title on a house or automobile and in some cases for court procedures. You should make this request when ordering the certified copies.
