In certain situations, a will in and of itself may be more than sufficient. However, there may be various shortcomings. A will can require the courts to make a public announcement requesting all known and unknown heirs to come forward. If and when they do, they can contest the will and tie up the estate for years, thus depleting all of your assets from your hard-earned work and incurring fees that would not occur with a living trust. Finally, a will does not include financial and health powers of attorney nor will it include any documents naming primary/secondary guardians for minor children and their inheritance if any.
