I would seek out a local Litigation attorney, not LL/T, to discuss this matter with.

(Remember, it's not whether you are right or wrong, it's what your underwriter will insure)Ok, that said, first you need the basics the most important sites or offices will be, your property appraiser/assessor, your clerk of courts/register of deeds/official records search, your tax collector, and your local civil records section of the clerk of courts.

They'll say it's a civil matter, which it is.  

As property owners, what are our rights, how do we ensure we are protecting ourselves from litigation and liability.

There is an eviction hearing pending in civil court and is on hold pending the stay from bankruptcy court.  

This is what I found:From the Ohio code:http://codes.ohio.gov/orc/4735.09"...has not been convicted of a felony or a crime involving moral turpitude, and has not been finally adjudged by a court to have violated any municipal, state, or federal civil rights laws relevant to the protection of purchasers or sellers of real estate..."

After Allison in 2001, Houston underwent massive civil works projects for flood control.  

on November 8th I filed a suit against her in special civil division court.

I've no idea why anyone is saying "evict them", this is straight forward trespassing of an unoccupied building without the consent of the owner.This isn't a civil matter, this is criminal trespassing and is a misdemeanor.Knock on the door and demand they leave.

No offense taken, I understand where you are coming from, but I must stringently disagree with your assessment as an attorney who regularly appears before Courts in a litigation capacity.
