When is a will invalid?

A will is a person’s final wishes for the dispersal of his or her property and assets, and unfortunately, sometimes a will can be considered invalid. For instance, if a person was not mentally healthy when writing the will it may be deemed invalid. Additionally a will may be considered invalid if the writer was writing under duress or force, or if the executor of the will did not carry out the terms of the will with integrity. Additionally, if any part of the will is inauthentic or inaccurate, legally it could be considered invalid.
