Need help in NY - GF wont leave apt

[Marci Stein]

I’m writing this for a friend. 

He rented an apartment and has moved out when lease was up - he didn’t  renew. 

His ex gf  refuses to leave . 

She’s there 1 month , 

the owner is telling my friend it’s up to him to evict her . She won’t pay rent , 

Is that his responsibility? Will he need to pay rent still , even though he returned the keys? ( ex GF made a copy ). 

Any help greatly appreciated .

If only HE (boyfriend) was on the lease and GF was not, I would believe that the landlord can call police for trespassing at this point. Unsure what NYC squatter rights are though, which could play a factor. I think the boyfriend should contact an attorney to evaluate the issue.  If anything, the attorney can determine who is responsible and if it's the landlord (to deal with the issue I mean) then a legally drafted letter sent to the old landlord should help your friend be free of the issue
