"A lawyer that operates on contingency CAN be a better advocate for your rights..."
Everyone has their own opinion...even those who think giving up to 40% of any damages won to their attorney AFTER the costs of bringing the action is paid for off the top.
Glad your agent had his/her eyes open...obviously the best defense to getting screwed is picking the right folks. Glad nobody sued you for having the roof fall on them.
I've been the arbitrator on several home purchase deals. Folks who buy (or sell) generally don't want to wait 2-3 years for a trial, and then a possible appeal. They get their rights interpreted quickly, and the case is closed. Why let someone "win" by making you give up by having to wait too long?
The only part of the legal profession which objects to overhaul are the plaintiffs attorneys. Alternative dispute resolution is favored by everyone else...consumer groups, chambers of commerce, etc.
