Usually, a consent judgment is not appealable unless one party to the suit can prove that s/he was forced into such consent through fraud. However, a consent judgment can be set aside on a motion by you to set this consent judgment aside based on ineffective counsel.
You would need to file this Motion to Set Aside in the same court and attached a copy of the original judgment as an exhibit. In the motion, you would argue that you only entered into this agreement at the recommendation of your attorney. You have later come to realize that you were misled and that the judgment will irreparable harm you if not set aside.
I would urge you to hire another attorney to file this document for you. That attorney would have to make an entry of appearance on your behalf and then file and argue the motion.
That said, you can handle this yourself if you feel like you do not want to utilize an attorney again. This is not incredibly complicated and sites like uslegalforms.com will have sample motions to set aside that you can follow for a nominal fee.
