There should be an official option to cancel a signed contract if the other party breaches that contract. In my case, I have a room rental that we both signed and the tenant tells me he does not have the funds for the security deposit which is a requirement when signing the agreement, He told me he will give it to me when he arrives in 15 days, but that is not the agreement. Therefor I am terminating his contract for breach. But I cannot cancel the contract in Adobe.
