In the secular world, there is a legal aid system. There is no reason why WE can’t establish a legal aid system in our society. After all, we have managed to establish Bikur Cholim, Hatzolah, Community Councils, etc. One brave person decided it needs to be done and did it. Maybe it has to be done within the Jewish Lawyers Association. If Jewish Lawyers as a group each agree to give of themselves, pro bono hours, then the community as a whole might be willing to step up to the plate and contribute to a fund that pays discounted fees to help those who cannot afford to pay for legal assistance. As long as there is a board who overseas the funds, the payments and the commitment of the attorneys involved. Law students should be able to get credits for assisting lawyers working these pro-bono and discounted cases as well.
Maybe there are some retired lawyers and judges who would serve as board members or even volunteer hours to get such an organization under way.
