Georgetown University has a legal clinic/resource center that may be able to at least point them in the right direction. Catholic Charities, and other faith communities, have resources as well. Justia.com has a directory of attorneys that handle landlord/tenant matters…some do pro bono work; however, there’ll be a lot of calling and repeating the situation to find out who may be willing to help. Also, the DC Office of Aging (I think that’s what it’s called) could help. L/T lawyers in this town are generally very expensive and hard to come by because it’s a very small circle of practitioners.
