fights are verbally agreed
What's the point in specifying that "fights are verbally agreed"? As far as I am aware of, oral contracts have pretty much the same validity as written contracts. E.g., from https://en.wikipedia.org/w/index.php?title=Oral_contract&oldid=759606175:
In general, oral contracts are just as valid as written ones, but some jurisdictions either require a contract to be in writing in certain circumstances (for example where real property is being conveyed), or that a contract be evidenced in writing (although the contract itself may be oral). An example of the latter is the requirement that a contract of guarantee be evidenced in writing, which is found in the Statute of Frauds.
Similarly, the limitation period prescribed for an action may be shorter for an oral contract than it is for a written one.
The term verbal contract is sometimes incorrectly used as a synonym for oral contract. However, a verbal contract is one that is agreed to using words, either written or spoken, as opposed to an implied contract.
Let's assume that the contract was made in the United States.
