Details: A guy brought a summons to my house saying my dad is being sued over an account with a bank that I know he does not do business with. The guy with the bad account & true recipient just has the same name as my dad. The messenger would not leave the paperwork with me, he wanted my dad to get it. He did allow me to snap a photo of the lawyer's info on the final page of the paperwork.
Who should my dad contact to clarify that this is mistaken identity?
edit: To my responders...Thanks!
