As Rushia pointed out: they can lie all they want. You don't "need" to in the sense that it's not required - but you need someone to adequately advocate for your side, and if you're not prepared to do it yourself, then get a lawyer.
Might I also point out: they can also be stupid idiots who are barely functionally literate. She looks good if she bullies you into agreeing to something more than the court would order.
My take on this: anything involving court will start with an initial hearing, not a trial. Stop hyperventilating, start looking into Rushia's suggestion, as you may indeed quality for a court appointed lawyer. Start putting your paperwork in order. It is very important to have everything you think you could possibly need with you, and easily found - even if you do get a lawyer. It has been my experience that if anything is needed, it will be the least obvious thing to you. And even if you have a lawyer, s/he can misplace the most important things... It is better to be ready and not need things than to be caught flat-footed.
