The following is a list of links that I have found to be helpful.

Estate Planning

Wills on the Web. Where else can you find Babe Ruth's will?

Estate and Trust Administration

Internal Revenue Service. Here you can check out information relating to the federal estate tax (and forms relating to other taxes, such as the gift tax and the income tax). You can even download forms and instructions.

Illinois estate laws. These laws deal with the administration of estates for the deceased and for disabled individuals. Perhaps the most important of these laws is the Illinois Probate Act.

Illinois trust laws. These laws deal with the administration of trusts. Perhaps the most important of these laws is the Illinois Trusts and Trustees Act.
