Although most states maintain their own organ donor registries, it is critical to state your wishes to your next of kin. Most states allow individuals under the age of 18 to donate with permission of their parents(s) or legal guardian(s). Some states have pre-death authorization on their organ donor registries that are legally binding and cannot be overridden by family wishes. However, organ donation goes more smoothly if everyone is on the same page. Talk to your loved ones today.
