One of the key complications of verbal arrangement is its enforceability. The courts though will be able to draw the fundamental provisions of the contract in order to enforce it, yet it may be difficult if the case is about he said that and she said that. (Chambers and Partners, United Kingdom)

Of course, proving a verbal arrangement can be difficult given that it isn’t recorded anywhere. (The Law Office of Michelle Cohen Levy, P.A.)

With this in mind, oral contracts should be reserved for simple agreements – the simpler the contract, the less chance that both parties will find themselves in court disputing the unspecified details of a verbal arrangement. (360 Business Law)
