It sounds like the tenant has solid evidence their check or auto payment was received by the wrong party.  

I have personally not seen the new evidence you have - hopefully that has gone to the right authorities. 

Quote from @Jonathan Greene: There are a million ways you could go with it, but your first thought I would say isn't grounded in evidence (a video on BP).

If you find discrepancies, you can submit a rebuttal to Kiavi with supporting evidence (e.g., better comps, rent roll, market trends).

But make that police report with the video evidence as the insurance company is going to want a copy.

Once you clarify where you are and where you wan to be the answer should be self evident to you.

you can always call or email the tenant in regards to this matter. i personally smoke as well and just would want my tenants happy and not feeling accused as its a big problem with a lot of tenant v landlord situations around the country. you can always say you got a report of the odor of weed and was just verifying the smell with both tenants on the property. you can restate your conditions with smoking. you can always ask if they are legally able to do so as well (meaning medical card). depending on how you want to handle it, if you want to make it a legal warning to the tenant as well, you should write a written letter sent by mail stating you got a report of weed and this is a written warning in case this a problem down the road, you have evidence to show the court if it gets to that matter that this is not your first occurrence. best of luck!

I love how Airbnb just pay me based on the evidence without going through 6 months legal battle or 3 years of collection hunting. 

They appellant must show the trial court made an error, either of law or procedure; an insufficiency of evidence; or an abuse of discretion. 

to me the biggest evidence of global warming is the Pine Beetle infestations.
