I would see this in court all the time.The judge will ask the tenant for proof of communication about each issue to be fixed.If they can't provide the proof in writing (letter,e-mail,certified mail,etc.) they sent to you then the judge will not validate the claim.If it is in writing then you would have needed to save your receipts as a landlord and take before and after pics.If the tenant says it has mold etc. then the judge will say if it is unhealthy for you to stay there then WHY haven't you moved??
