I agree, take a loan, do whatever you can to pay because if your case has gone as far as needing an evaluator, you want to show that you can provide for your child(ren), and if you can't afford the court fee, then it looks like you can't afford much else. My evaluation fee was either $100 or $200, and i only had to pay half of that. And my advice on the evaluation, be honest, don't be accusatory or angry, share your concerns, and be realistic. Make it 100% about your child(ren) and not about punishing the ex. Don't come off as bitter. And make sure your home is clean.... Good luck.
