Is this a divorce or custody order? It is not unusual for the court to not expressly rule on every issue from the bench, Usually, the lawyers work with each other to hammer out those details. You should be included in that process, of course.
I don't see how you signed something that was different than what you thought is was. Did you read it? If not, why not?
It will be hard for you to make a claim when you agreed in writing. But, you can use the "Find a Lawyer" tab above to locate a local attorney to evaluate your case.
The best thing you can do is speak to another attorney who handles the same practice area. Ask him/her if your lawyer messed up, and if so, whether anything can be done about it. Legal malpractice cases are actually extremely rare, because you need to be able to prove (a) the lawyer violated the legal standard of care which (b) resulted in significant damages. You also need to be able to prove that the result in the underlying case would have been different but for what the lawyer did.
I am licensed in Pennsylvania. Members of my firm are licensed in various states, including Pennsylvania, New Jersey and New York. We handle cases involving personal injury (car accidents slip and falls, etc.,) medical malpractice, nursing home abuse, workers' compensation, social security disability and legal malpractice. Nothing I write on Avvo is legal advice, but instead contains general educational information. Please do not act or refrain from acting based upon what you read in anything I write on Avvo without retaining your own lawyer in your state. Also please remember that this post does not form an attorney/client relationship between you and me. If you have specific legal questions, you should contact an attorney in your state for assistance.
