Do I need an attorney in order to make a rebuttal on a contested dissolution of marriage?

You would file a Response to the Petition. It is on or before 30 days from the date you are served the Petition. You can hire a lawyer, or do the Response yourself, or get assistance in filing the Response. If you are dealing with a request for orders that have a court hearing date, you may want to consult with a lawyer about preparing a responsive declaration which is due 9 court days before the hearing.

No, you can do it yourself. Go to the self help department at your courthouse.
