A last will and testament (commonly known simply as a "will") is a legal document identifying those persons (beneficiaries) you wish to receive your property upon your death. In addition a will nominate a personal representative (executor) to be responsible for the proper administration of your estate and the disposition of your property to your intended beneficiaries. Shortly after your death, the person or entity you nominated as your personal representative opens a probate proceeding in court and asks the judge to appoint him or her as the personal representative of your estate. After being appointed, your personal representative manages your estate’s financial affairs and ensures that your property is distributed in accordance with your wishes. A will can also nominate a guardian in the event you are survived by minor children. Each state has intestacy laws (laws that govern the disposition of one's property if he or she dies without a will). Having a valid will is essential if you do not want your property to pass by the laws of intestacy.
