More than 400 lawyers have volunteered to represent 416 children removed by Child Protective Services from a secretive polygamist ranch in West Texas, says an attorney coordinating the effort.

On April 11, 51st Texas District Judge Barbara Walther decided 350 attorneys are needed to represent the children as ad litems in the CPS removal proceedings, widely considered to be the largest family law case in Texas history. Walther is holding a statutorily mandated hearing today in which CPS attorneys will have to show why the children from the Fundamentalist Church of Jesus Christ of Latter Day Saints (FLDS) should remain in state custody. The court is currently processing the names of volunteer ad litems and assigning them to FLDS children.
