My son's biological father said he changed my son's last name and I received papers from the court saying he was allowed to do so, however, I was never notified there was to be a court hearing. Now he says his attorney told him he can change my son's middle name just by filling out an affidavit form. The biological father lives in another state and the papers I received about his last name were from his home state even though my son has never lived there. Can a judge order a name change without notifying me, the custodial parent? And shouldn't all court hearings related to my son take place in the state in which my son lives?
