In order to make and execute a valid will under New York law, a person must meet certain requirements. One of these requirements is that the testator or person creating his or her will have testamentary capacity. Testamentary capacity refers to a person’s ability to understand and execute a will. Generally, most people over the age of 18 who have reached legal adulthood are considered competent to make and sign a will. They understand the nature of the document they are creating and signing, the property that will be passed and understand the effects that the document will have after their death.
One of the most common bases for contesting a will is that a person lacked testamentary capacity and for good reason. There are many ways a person can lack testamentary capacity and many of them relate to illnesses and conditions that are common in old age. In particular, challenges arising out of accusations of the testator being mentally incompetent or under undue influence are not rare, especially if the testator is of advanced age.
