Will

A Will or Testament is a legal document that expresses a person's (testator) wishes as to how their property (estate) is to be distributed after their death and as to which person (executor) is to manage the property until its final distribution. For the distribution (devolution) of property not determined by a will, such as inheritance and intestacy.
Though it has been thought a "will" historically applied only to real property, while "testament" applied only to personal property (thus giving rise to the popular title of the document as "last will and testament"), records show the terms have been used interchangeably. Thus, the word "will" validly applies to both personal and real property. A will may also create a "testamentary trust" that is effective only after the death of the testator.
