This was never an area of law I sought out, but I'm becoming well versed in it out of necessity.
One time I was asked while I was applying to law school why I wanted to be a lawyer and I joked about the statistics of lawsuits and she said "so out of self defense."
In a way, that comes true. I am on my condo's board of directors and I have to keep checking the law on various things. I just drew up a waiver in case anyone wants to start doing improvements on the grounds on their own - because someone already has been and if he gets injured I think we should have a better defense.
