If a person provided protection under this chapter is named as a defendant in a civil cause of action arising prior to or during the period in which the protection is provided, process in the civil proceeding may be served upon that person or an agent designated by that person for that purpose. The Attorney General shall make reasonable efforts to serve a copy of the process upon the person protected at the person’s last known address. The Attorney General shall notify the plaintiff in the action whether such process has been served. If a judgment in such action is entered against that person the Attorney General shall determine whether the person has made reasonable efforts to comply with the judgment. The Attorney General shall take appropriate steps to urge the person to comply with the judgment. If the Attorney General determines that the person has not made reasonable efforts to comply with the judgment, the Attorney General may, after considering the danger to the person and upon the request of the person holding the judgment disclose the identity and location of the person to the plaintiff entitled to recovery pursuant to the judgment. Any such disclosure of the identity and location of the person shall be made upon the express condition that further disclosure by the plaintiff of such identity or location may be made only if essential to the plaintiff’s efforts to recover under the judgment, and only to such additional persons as is necessary to effect the recovery. Any such disclosure or nondisclosure by the Attorney General shall not subject the United States and its officers or employees to any civil liability.
