If you want a change of custody or to restrict visitation, then yes, the more proof you have, the better your chance of success. However, with the situation you have described, I think success will be difficult, but not impossible. You will need more specifics in addition to the father having an off-again/on-again relationship. As for free lawyers, check your local legal aid office.
