Suppose that I am afraid someone might challenge my will. How can I ‘bullet proof’ it?
First, a Will is such an important document that you'll want to have a lawyer help you draft it, even if you do not fear someone may challenge it. You'll want to make sure it does what you want it to do, without ambiguity, with the lowest expense possible when it comes time for probate, and that it helps you and your family avoid or minimize taxes. That's what good lawyers do.
Second, if you tell the lawyer you suspect challenges, they'll work extra hard. They may ask a physician to evaluate your mental competence -- and perhaps serve as a witness when you sign it. They may videotape your execution of the Will. And they may put in provisions that would result in anyone challenging the Will to increase his or her share getting nothing at all should the challenge fail.
