Legal Question in Constitutional Law in Maryland

Court houses do not typically call people asking to know their relative's whereabouts. Perhaps someone has sued your former brother-in-law, is trying to find him to serve and in their research discovered a link to you. Or perhaps this is an aggressive debt collector who is falsely stating that they are a courthouse.

You can simply explain to whomever calls that you are no longer related to this individual and do not have a current phone # or address for him. Ask for the name and address of the company calling. Perhaps ask to talk to a supervisor and request that they update their files. If the calls continue after that, you may wish to log them and if they cross the threshold of the Fair Debt Collections Practices Act you may want to review the situation with an attorney.

While the above is not legal advice, I hope that it helps.

I agree with Ms. Laumann. Let me add that the fact somebody is calling you does not mean your brother gave them your information. They might well have found it on their own.
