Tenant eviction after lease violation

[Kranthi Pabba]

Hi,

I have a two family home with a unit downstairs and another upstairs. I recently had new tenants occupy the 2nd floor unit and since then problems started. My long term downstairs tenants have had issue with the upstairs tenants yelling and fighting in the middle of the night causing a lot of disturbance to them. Police were involved a couple of times. Upon further research we found out that one of the persons upstairs had arrest history but nothing was shown in zillow background check. 

Long story short, I sent a notice to vacate citing the disturbance and violation of lease (lease mentions no disturbance as one of the terms). 

The tenants hired a lawyer and want to fight it out. I am looking for any suggestions for a good attorney who could represent me to fight eviction, any contacts will help.

Also, what background verification service is good which provides information of past arrests as well, Zillow service is not good.

Any help is greatly appreciated.

Thanks
