Contractors tend to avoid calling for legal help. Partly this is because they're used to solving their own problems, and partly it's because they don't want to rack up attorney's fees. But certain circumstances — let's call them legal emergencies — absolutely require immediate legal counsel.
Say a GC signs a contract to build a fence for a homeowner. After the job is done, the homeowner hits the fence with his car but does not repair the damage. A couple of weeks later the fence falls on a neighbor who is walking down the sidewalk. Who is liable for the neighbor's injury?
