Property you transfer into a living trust before your death doesn't go through probate. The successor trustee -- the person you appoint to handle the trust after your death -- simply transfers ownership to the beneficiaries you named in the trust. In many cases, the whole process takes only a few weeks, and there are no lawyer or court fees to pay. When all of the property has been transferred to the beneficiaries, the living trust ceases to exist.
