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.
Kinds of Wills
Here's a brief glossary of terms used in the law for various kinds of wills:
Simple will. A will that just provides for the outright distribution of assets for an uncomplicated estate.
Testamentary trust will. A will that sets up one or more trusts for some of your estate assets to go to after you die.
Pourover will. A will that leaves some of your assets in a trust that you had already established before your death.
Oral will (also called nuncupative will). A will that is spoken, not written down. A few states permit these.
Joint will. One document that covers both a husband and wife (or any two people).
Living will. Not really a will at all--since it has force while you are still alive and doesn't dispose of property--but often executed at the same time you make your will. Tells doctors and hospitals whether you wish life support in the event you are terminally ill or, as a result of accident or illness, cannot be restored to consciousness.
Living wills are not really wills at all. Instead, a living will (which also may be known as a healthcare directive or directive to physicians) is a document that expresses a person's desires and preferences about medical treatment in case he or she becomes unable to communicate these instructions during terminal illness or permanent unconsciousness. The first living wills helped people who wanted a natural death unattended by artificial life support and other advanced medical techniques. As these documents became more popular and widely available under local laws, they came to include other health care concerns such as tube feeding, resuscitation, and organ donation. While living wills are allowed in all states, they sometimes must follow certain formalities to be effective. If valid, a living will binds health care providers to its instructions.
