Washington Attorneys Assisting Community Organizations (WAACO) has some terrific nonprofit legal resources available for free on its website.

First, there is the 2009 edition of the Washington Nonprofit Handbook: How to Form and Maintain a Nonprofit Corporation in Washington State published by WAACO and the King County Bar Association Young Lawyers Division.  This 200-page book covers formation and governance of a nonprofit corporation, obtaining and maintaining 501(c)(3) status, and topics such as international activities and grantmaking, employment issues, and intellectual property considerations.

There are also sample forms, such as articles of incorporation and bylaws, and a nonprofit legal self-assessment checklist.
