Backdating a new real estate lease nys
I am a real estate agent, and my office took an application for an apartment on May 12. The landlord prepared the lease on May 17, and we faxed it to the guarantor on the May19. We received the lease back on May 27, and the tenant agreed to take legal possession of the apartment for June 1. However, the landlord wants to charge the client beginning May 1.
I told him that it is illegal for him to backdate the lease, and it is illegal for me, as an agent to participate in a transaction of this nature.
When I told him this, he responded saying, "we can all learn something new, so show me where the law prohibits his backdating the lease, assuming that the tenant agrees."
I would not only like to show him where the law says that he cannot backdate the lease, but also that I am not permitted to be party to this.
His is paying our commission, and has determined to discount our fee if I fail to prove to him that he is in violation of the law. My question is, is there such a law, what is my legal obligation as an agent, and can you tell me where I can obtain the information that I need to refute the landlord's action.
