Stacey L. Bradford has put out "The Wall Street Journal Financial Guide for Parents." In it, she talks about how many parents should be setting up trusts.

Ask the attorney whether they offer a free plan review (at least every 3 years) and whether they have a membership program for ongoing legal needs. We see many trusts fail because of little issues that could have been prevented with better client service and communication.
