An advocate is someone who speaks on behalf of another person, especially in a legal context. Implicit in the concept is the notion that the represented lacks the knowledge, skill, ability, or standing to speak for themselves. The broad equivalent in many English law-based jurisdictions is "barrister". (http://en.wikipedia.org/wiki/Advocate)
Although the homeowner path to recovery and justice will be long and painful, that path would not be possible without the determination and perseverence of so many dedicated attorneys and homeowner advocates.
