I agree with everyone who mentioned the importance of a written agreement, and I agree with your point Roberto. The only part I would like to comment on is about the condition you set for verbal agreements. I have seem some cases of long-life friends who conducted businesses together based on the relationship trust, but at some point influences change one of them toward the other and someone ends up losing. I would say that any form of verbal agreement on major deals or businesses is a lost deal.

An interesting example of the importance of written agreements was brought up in another class, was about the company named Tesla. When the crashes of their self-driving cars discussion was raised, a student mentioned their long agreement or catalogs that list a lot of legal warnings that protect them as a company. In a lot of cases people are not able to sue these companies as they cover themselves well with these written agreements.
