I agree because at first when I read what kbs27 said I was very confused because they used verbal and oral and I assumed they were both the same. But as you have stated they are not because verbal can also mean written. I believe that to stop the confusion and avoid trouble written agreements should always be used. Oral agreements are only as good as the people making them. If you make an oral agreement it is not easy to go back and say this happened because they isn’t much proof besides the people who were there. Written agreements on the other hand always have proof because it is written down and then usually signed off meaning they agree with it. So agree that oral agreements should be compared with written agreements and that written agreements are almost always better.
