Ademption by extinction is when the testator's estate no longer contains the property or asset that was intended to be bequeathed to an individual. The testator may or may not have included a substitution or provision for just such an occurrence. This is where good estate planning becomes important. An estate planner can help individuals plan for scenarios such as these, such as willing a car to a grandchild and at death the car is no longer a part of the estate. An estate planner can add wording so that the grandchild is given the equivalent of the car that was originally part of the estate. The goal is that the will contains express intent should ademption by extinction arise.
