Though it may be difficult, ask your sister if there is a will. We learned the hard way that making a will is a loving thing to do for one's family. If there isn't a will, have her get a copy of the death certificate, get the appropriate forms filled out (often you can find them in a kit prepared for your state--see a local bookstore) and take it all to the county probate court right away and be declared his administrator. The odd thing about probate is that in some places anyone who gets there first can get permission to be administrator, and can make an expensive mess in the process. If she has an attorney to do it who she trusts, good. But she can take care of all of it herself, or hire an attorney to assist.

The world swirls past at a time like this. Be there for hugs, for support, and to make sure that she eats something regularly. Good luck.
