If you think it's their fault for leaving it out, have the tenant sue you in small claims court if they disagree, but don't ever agree to a rent credit or abatement. 

ThanksAbhijeet You need a bankruptcy attorney to represent your interests in bankruptcy court.

There's no mechanism, short of a seller trying to sue someone in court for fraud, to clamp down on unethical individuals.

What's not clear in the law, is often times easily dealt with in court.

I was wondering if anyone had foolproof ways of time stamps and if anyone had any experience or stories about being challenged in small claims court.  

Go to your county courthouse and request civil court records / eviction filings (every county is going to be different, some will be easier to work with than others) 

It is required prior to evicting, make sure you read the requirements for the 3 day notice because one slip up on it and you may end up having to start the process over again (little things like not having your phone number, not having or an address within the county to mail rent to, including other fees other than rent in the amount due) or counting days that do not qualify in the 3 days such as the day you post it, weekends, or court holidays)They were able to push the last landlord around, don't let them do the same to you.
