One place I've often turned for legal information is a company in California that publishes self help legal materials, called Nolo Press. They are one the web at
www.nolo.com .
The publish things on many topics that may be of interest to people here, such as how to adopt your step child in california. The also have a book out on marraige / family based visa. They also have a couple of good items on wills, which I have used.
I have used their materials to educate myself on legal issues and have felt more comfortable dealing with a lawyer.
