The primary difference is their relationship with the court system. A will is essentially a set of instructions for the probate court; it has no legal power until the court validates it, meaning a will guarantees the probate process. A living trust, however, is a separate legal entity created to own assets. Because the trust, not the individual, legally owns the property, those assets are not part of the deceased’s personal estate and therefore do not need to go through the court-supervised probate process for distribution.
