The issue I am running into is tenant/landlord litigation. 

Is anyone that is showing real estate for sale, rent or otherwise, using a COVID disclosure to indemnify themselves against possible litigation from would be buyers, renters etc, in the event they got COVID and decided it was your fault and now you're gonna go through the court system?

California Civil Code 1189(b) provides that any certificate of acknowledgment taken in another place shall be sufficient in this state if it is taken in accordance with the law of the place where the acknowledgment is made,” according to the SOS statement.”https://www.nationalnotary.org...Appears you could find a RON from another state and have it done that way.

Also is it worth it to seek civil or criminal charges against them?

Have a dollar amount that you are willing to defend against if litigation arises.....example 5 properties in 1 LLC worth $1M.  

In the state of Florida, my understanding is if you have less than 5 properties and it's owned personally, you are not subject to civil rights requirements since it's your personal property.

But I've seen cases litigated over whether the party initialing the contract had the authority to do so.

And the sheriff will not assist with doing a civil stand by either.  

However, if you're convinced the foreclosure is defective why would you want to get involved in what could be protracted litigation and tie up your money?

I agree with the threat of one of these actions.. but in reality they are not that easy to litigate..
