If you have been looking for information about wills, you may have come across the "self-proving" will. This is like any other will, but it has one additional component. In estate law, a self-proving will has a sworn statement attached. This statement is created by the witnesses who observe the signing of the will. As such, these wills have an extra layer of security when it comes to proving its validity. See what else you should know about self-proving wills in the state of Utah.
