So your parents have a Last will and Testament or a Living Trust. Great. It was signed by all the proper parties, contains the proper language, and appoints the proper people. Wonderful. And to top it all off, the attorney's gave you an unbelievable deal. Excellent (unlikely, but excellent). The problem? Those documents can still be thrown out by the court if your parents lacked one key thing: testamentary capacity.
What is Testamentary Capacity?
We lawyers sure do like our big words. Fortunately for everyone, testamentary capacity boils down to a pretty simple idea: Does the person signing a Will or Trust understand what they're signing? To have testamentary capacity in Oklahoma, the testator (the person signing the Will or Trust) must understand, in a general way, (1) the quality and quantity of his or her property (sometimes called their "bounty"), (2) the natural objects of his or her bounty (i.e., who should logically inherit their property), and (3) the legal effect of signing the document.
