One more thing that our business law instructor covered was duress. Basically, he said that we should never threaten to sue somebody or drag them to court. It opens the door to a "Duress" issue that can enable people to weasel out in many circumstances. If we say that we will "call our attorney", that's not considered a verbal threat - that's a fact about who we will call. But apparently there is a big difference to declare a legal assault or confrontation on someone who owes us money. The instructor said there was no need to threaten. Since we can still persue legal avenues.
