Forensic social work is a practice specialty that involves interaction with the courts. It has emerged as an important field in the past several decades. Forensic social workers often are involved in making recommendations regarding competency, involuntary commitment, risk of violence, and alternative sentencing. They conduct forensic interviews and psychosocial assessments, and testify as expert witnesses. They also provide treatment to court-ordered offenders. Their influence is felt in cases of domestic violence, child maltreatment, custody, mental health, immigration, elder abuse, divorce, visitation, foster care, adoption, criminal and juvenile justice, substance abuse, and probation and parole.
