Organ and Tissue Donation
If you wish to give parts of your body to others after your death, you will is not a good place to do it. Your will won't ordinarily be procured and read until well after organ transplants must be made.
However, gifts of organs can be made by will and the gift is effective whether or not the will is admitted to probate and even if the will is later successfully challenged, to the extent the gift was actually carried out.
Organ gifts can be made as part of the issuance of drivers licenses. They can also be made by separate document executed before 2 witnesses like a will. Read more at Chicago Estate Planning Lawyers.
