First off, I don't much care for lawyers. I was one until I grew up and got a real job. Still, there are times when it is a very good idea to consult a lawyer.
Putting together a living trust is one of those times.
Why? If you have enough money to consider setting up one so that your assets will pass on to heirs without the complications of probate and avoid some estate taxes, you can afford a lawyer to put together a trust that will meet your needs. Also, good attorneys will give you a free consultation to you can determine what your needs are, what the advantages are of various estate plans, etc.
Of course, it's your money, but do you want to leave something as important as estate planning up to a piece of "one size fits all" software?
