There are three very different kinds of guardian ad-Litem; Volunteer, Staff, and Lawyer.
1) Volunteer CASA GALs generally take just a few cases and get to know the families and children in the court proceedings very well. CASA stands for, Court Appointed Special Advocate. as a CASA GAL, I had fifty children in my case load over twelve years. Some of those children stayed with me over the entire twelve years. I knew them and their families very well.
2) Staff GALs are given case loads similar to case loads that social workers are given. In my experience, staff GALs have more cases and less time per child/case.
3) Attorneys are paid by the County or by the parent depending on the state. In my experience, attorneys rarely visit the family, and generally meet the child for the first time at court.
