Estate planning documents decide what happens to your property, your children, and your medical care when you cannot make those decisions yourself. Wills, trusts, powers of attorney, and health care directives each serve different purposes and each have to meet state law requirements for signing, witnessing, and notarization. A document that looks fine on the page but was not executed correctly can be rejected in probate, which is exactly when it is too late to fix.
