I've been through arbitration once and won. I did not need to really provide anything remotely close to legal documentation tier stuff, I had one recording of a sales rep absolutely lying their ass off to close a sale, the next month's invoice directly contradicting their repeated and explicit promises. Arb awarded me 3x the total cost of the contract (several thousand) and considered the contract terminated (instead of 24 month + ETF being to pay out the entire cost). It honestly felt closer to "we will pay the arbitrators their $1k fee so that we don't have to pay the lawyers $50k, and whatever prize they award you is still going to be cheaper than asking our general counsel a single question".
