The father should have been served with the petition/motion for custody. It sounds like it may be possible she didn't actually ever file anything, she's just threatening him. There is no apparent reason why he would not get joint custody if he files a Request for Order (assuming there was an existing case or a Petition if there isn't an existing case). He will not lose any rights by filing for and getting a court order for custody, the mother is simply trying to intimidate him. He should either seek the help of an attorney or most courts have a family law self-help center that can give him the paperwork he needs to do it himself.
Good luck!
