A will is a legal document that disposes of a person's property after his or her death. This document lets you control what happens to your property and affairs, and enables you to designate a guardian if children are involved. Without a will, the probate court will assign someone to comb through your property and other affairs and distribute them in accordance with state law. Your property or assets may go to family members or relatives that you did not intend them to. State law governs the validity of wills and requires that the form and execution of wills meet certain requirements. Also, a will may be revoked and amended at any time during a person's life. To properly draft a will and ensure compliance with the law, you should consult with a qualified attorney.
