In all family law proceedings, such as divorce, where public assistance is assigned or the public authority provides services to a party or parties to the proceedings, information on the location of one party may not be released by the public authority to the other party if the public authority has knowledge that a protective order for the other party has been entered or the public authority has reason to believe that the release of the information may result in harm to the other party.
If the public authority has statutory authorization to disclose information, then it must comply; but the rule of thumb is that information will not be disclosed.
