The Court Liaison Services Unit is located in the Pretrial Services main office. The primary function of this unit is to present cases to Common Pleas Motions Court for attorneys seeking bond reductions or bond revocations and present the reinstatements of bonds that have been forfeited due to failure to appear. Motion hearings regarding bail are held daily, and a member of the court staff is always present. Reevaluations are completed on all cases where a request for a bond hearing has been made. Any new information is placed into the risk assessment tool, and the recommendation is presented in Motions Court. The Court Liaison Unit is also present for all video hearings conducted in Motions Court from the Allegheny County Jail involving defendants who are incarcerated due to apprehension on a failure to appear bench warrant. The investigations on incarcerated defendants are completed by the Bail Unit Investigators at the Allegheny County Jail.

The Pretrial Services Bail Court Liaison Unit also offers a "safe surrender" program. This program enables defendants with active bench warrants for failure to appear to report to the Pretrial Office by 9:00am, Monday through Friday. These defendants will be escorted to the Allegheny County Sheriff's Office for surrender on those warrants and be seen in Motions Court that same day to resolve the warrant.

The Allegheny County Pretrial policy on Bail Modifications and the form for attorneys to submit a bail modification request are located on the main Bail Services Home page.
