What Do I Have to Do to Get My Ex to Move Out

My question involves an eviction in the state of: NYC

I've seen a couple of threads for this in other states, but I know that NYC is exceptionally difficult for subletter's to get evicted.

I'm the only person on the lease. We paid a large broker's fee to get the apartment, I paid 1300, she paid 900. We broke up. She's refusing to leave. Two things:

1) What do I need to do, and what's the soonest I can get her legally out of here.

2) She's demanding that I pay her the 900 for the fee or she'll sue me. Does this hold water, even though she gave me the 900 via wire transfer and then I paid the entire fee out of my own checking account - and the fee was simply for finding the apartment it has nothing to do with an annual charge for living here; or is she entitled to the money back. *there is no subletting contract or written or verbal agreement that if she were to leave I'd give her any money back*.

It's not clear that you have any right to evict her. She can argue that she has an oral lease with you for the (presumed) one year term, that she has contributed rent, and that she has done nothing to justify eviction for cause.

If you are trying to kick her out of the apartment she helped you rent, and are insisting that the apartment is exclusively yours, I can understand why she would want you to pay back the money she contributed for the broker's fee. If she's saying, in effect, "Give me the $900 and I'll move out," that actually is something you might want to consider.
