you don't need to by that logic everything you say ever is legally binding ifi say im gonna loan my mom 40$ and then sleep all day forgetting to pay her she cant sue me for all my stuff that's really stupid.They get enforced every day. They're difficult to enforce if the other party denies it and you don't have proof the agreement actually took place, such as them mentioning it at a later date, witnesses to the conversation, or a recording. Something you said in front of hundreds of viewers, for which a recording likely exists and can be got at during discovery even if the VoD was privated? Yeah no way you're going to "he said she said" your way out of that one.
Anyone in a legal profession relying entirely on an oral agreement is desperate even me with my limited study was told this repeatedly by my friends teachers and other students.
I suppose I could have phrased it better in the first place ill admit to that but even with actual cash being involved this is not something you can act on and realistically get a favorable outcome.
