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.
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.
