I find it hard to believe that the Trump organization would let one tenant sublet one of their apartments without submitting various legal papers ,including verifiable ID, from the new tenet.
“I find it hard to believe....”
It’s generally considered and legally established that it is within the a right of a lessee to sublet. It’s in with that bundle of rights a lessee has. IANAL and I sure don’t know NY law, but I’d suspect subletting cannot be denied.
