Never Trust in a Campbell WILLIAM CAMPBELL KIRBY took advantage of me, a person with autism. He mislead me and told me things that were not true to scare me into listening to his malpractice. He did not follow the law, and did not follow my written directions. Billy is not the hero he pretends to be. Like a used car salesman, Billy took advantage of me, bilking me for a lot of money, and setting me up for contempt of court. ... all the while pretending like he is my friend. I put 100% of my trust in him ... and then he quit, rather than fix his mistakes. This dishonest attorney is only out for his own financial gain, while not caring that it is to the detriment of others . Billy should not be allowed to practice law. If you also had issues with Mr. Kirby, please file your complaint with The Pennsylvania Supreme Court, Office of Disciplinary Counsel.

Q. My daughters mother has history of drugs and jail time. Do I have a chance for custody once I establish paternity?
A: The primary consideration by the court as to whether custody should be modified is whether it would be in the best interests of the child. The court decides this by reviewing a variety factors. If you decide you want to consider seeking custody, I suggest that you first meet with a family law attorney in your area to determine whether it's a good idea for you and your child.
