Depending on your economic situation, whether you own real proerty or not you may have two less expensive options. If you do not have real property and you are no longer being represented by an attorney, you can go to the Legal Aid Foundation's Self-help Center in either Inglewood, Santa Monica, or Torrance. The service is free and they will help you fill out all the necessary forms for free, you just have to pay for the photocopies and stamps. Depending on the center you can make an appointment and not have to be a walk-in.
Otherwise you may try Levitt & Quinn. http://www.levitt-quinn.org/help.htm. This firm specializes in handling divorces on a sliding scale basis depending on your ability to pay.
You may want to ask your former attorney to redo the paperwork or fix the situation based on the fact that he/she failed to provide you with competent legal representation by botching the forms. That is falling below the standard of care of an ordinary prudent attorney. The attorney is licensed by the State and is responsible for his work and if you are dissatisfied and he/she failed to remedy his poor work, then you can go to the State or COunty Bar and file a complaint.
I do not and would not suggest going to a paralegal. I have had to fix their work more times than I can count and they have no licensing requirement that holds them responsible for whatever work they do.
Good luck and I am sorry you have to go through not only a divorce but trying to fix what some incompetent attorney did not properly do for you.
