What type of attorney do I need if I discovered that the owner’s LLC is has been suspended by the Franchise Tax Board?

I've lived in a mobile home park for the past 3 years, in a home I purchased outright from an individual and before listing it for sale recently. He cannot legally contract with a new tenant, I am essentially stuck with a $20,000 investment sitting on a criminal’s (he is not paying taxes) property. Usually, there is no money suing a suspended corporation but I happen to know exactly what bank he deposits $75,000-$100,000 a month in. My background in judgment recovery tells me I will be able to recoup my investment with a judgment. From what I understand, a suspended Corp is a sitting duck liability wise. I would assume a judgment against it would be a sure thing as it is prevented from defending itself in court as it is essentially a defunct business.
