We are being sued! - Who is liable?

[Konrad Lightner]

Hi, 

One of our past tenants are suing because they claim that issues were not fixed in a timely manner (even though there is documentation showing otherwise).  Our property manager's lawyer is advising her that we as Property Owners are liable, not her as the property management company.  Even though she is responsible for dealing with tenants and repairs.  Our properties are in Minnesota.

Is this accurate?  Any insite would be greatly appreciated!
