This is the first comprehensive examination of the increasingly important role of forensic psychologists in consulting and expert witness testimony in child custody litigation. Offering practical advice on understanding the psychological dynamics often found in these cases, the authors use real-world examples where critical issues such as the developmental need of children, relocation, domestic violence, and the alienated child are involved. They detail a logical process for critiquing the evaluation reports of others and analyzing the strengths and weaknesses of a case.
