Depending on what you need, you can always sign up for prepaid legal. (Just Google it) my husband and I have it. You pay just a small amount per month and you gain certain things. Free calls, free letters and more. Just an idea :) we have used it for all sorts of things. And you even get a will done for free.
Call your nearest law school and find out if they have any clinics for low-income clients. Most of the services provided by law-school clinics are free to the client and they can often get your court fees waived also.
