Really not a lot unless dotting an "I" or crossing a "t" stresses you out. Most of the pressure lands on the big guys’ shoulders. Our legal system is complex, and there are a lot of ins and outs and loopholes and under-enforced laws to track and comprehend. Any little mistake can be costly, so you expect the lawyers you work under to be somewhat unforgiving in that department. But if you're one of those people who doesn't make mistakes, then great!
