A basic living trust isn't much more complicated than a will, and you probably won't need to hire a lawyer. With a good self-help book or software program, you can create a valid Declaration of Trust (the document that creates a trust) yourself. If you run into questions that a self-help publication doesn't answer, you may need to consult a lawyer, but you probably won't need to turn the whole job over to an expensive expert. To make a living trust online, see Nolo's Online Living Trust.
If you have a complicated estate or just need legal advice, Nolo can help you find a lawyer.
