A last will and testament is a common expression referring to the current form of a will at the time of reference or upon death of the party concerned. It's an anachronistic expression, using the word 'testament' to describe the comments, conditions, and basis of allocation of property in a will. A will is a document dictating the distribution of personal property after death, and is a legally enforceable document, managed by an executor. The expression may also be used as a metaphor for a documented mistake, or stupid action, like 'Is this your last will and testament, or a policy?'.
