Tenant purposely delaying court. NYC holdover.

[Steven Sun]

Hey everyone, I am a landlord from New York City and am experiencing a terrible time in a holdover case. The tenant had delayed court 3 times because she claim she was pregnant and had a c-section. She was able to obtain a doctors note and the judge is extremely tenant friendly. The reason why I am experiencing a terrible time is because I know for a fact that she was not pregnant and did not have a child. I have seen her smoking on the balcony lately and asked around the neighborhood. In addition, I learned from another tenant that she went through the trouble of reporting to the dept. of buildings that I have an illegal basement and is calling exterminators for roaches etc. I am terrified of these people and what they can come up with. Apparently she knows people that can help her, such as doctors etc. It's been almost 6 months since she was notified to vacate and hasn't paid a single dime. 

Is there anything I can do in this circumstance? Any help would be greatly appreciated!

Thanks
