Wills are the most common way for people to state their preferences about how their estates should be handled after their deaths. Many people use their wills to express their deepest sentiments toward their loved ones. A well-written will eases the transition for survivors by transferring property quickly and avoiding many tax burdens. Despite these advantages, many estimates figure that at least seventy percent of Americans do not have valid wills. While it is difficult to contemplate mortality, many people find that great peace of mind results from putting their affairs in order.

Wills vary from extremely simple single-page documents to elaborate volumes, depending on the estate size and preferences of the person making the will (the "testator"). Wills describe the estate, the people who will receive specific property (the "devisees"), and even special instructions about care of minor children, gifts to charity, and formation of posthumous trusts. Many people choose to disinherit people who might usually be expected to receive property. For all these examples, the testator must follow the legal rules for wills in order to make the document effective.

Will Requirements

Formal requirements for wills vary from state to state. Generally, the testator must be an adult of "sound mind," meaning that the testator must be able to understand the full meaning of the document. Wills must be written. Some states allow a will to be in the testator's own handwriting, but a better and more enforceable option is to use a typed or pre-printed document. A testator must sign his or her own will, unless he or she is unable to do so, in which case the testator must direct another person to sign the will in the presence of witnesses, and the signature must be witnessed and/or notarized. A valid will remains in force until revoked or superseded by a subsequent valid will. Some changes may be made by amendment (called a "codicil") without requiring a complete rewrite.
