Just about everyone needs a will. Besides enabling you to determine the distribution of your property, a will gives you the opportunity to nominate your executor and guardians for your minor children. If you fail to make such designations through your will, the decisions will probably be left to the courts. Bear in mind that property distributed through your will is subject to probate, which can be a time-consuming and costly process. Does a will avoid probate? No. Using a revocable trust does work in most cases.
