N.Y. Gen. Oblig. Law § 5-413
All things in action, judgments, mortgages, conveyances, and every other security whatsoever, given or executed, by any person, where the whole or any part of the consideration of the same shall be for any money or other valuable thing won by playing at any game whatsoever, or won by betting on the hands or sides of such as do play at any game, or where the same shall be made for the repaying any money knowingly lent or advanced for the purpose of such gaming or betting aforesaid, or lent or advanced at the time and place of such play, to any person so gaming or betting aforesaid, or to any person who during such play, shall play or bet, shall be utterly void, except where such securities, conveyances or mortgages shall affect any real estate, when the same shall be void as to the grantee therein, so far only as hereinafter declared.
When any securities, mortgages or other conveyances, executed for the whole or part of any consideration specified in the preceding paragraph shall affect any real estate, they shall inure for the sole benefit of such person as would be entitled to the said real estate, if the grantor or person incumbering the same, had died, immediately upon the execution of such instrument, and shall be deemed to be taken and held to and for the use of the person who would be so entitled. All grants, covenants and conveyances, for preventing such real estate from coming to, or devolving upon, the person hereby intended to enjoy the same as aforesaid, or in any way incumbering or charging the same, so as to prevent such person from enjoying the same fully and entirely, shall be deemed fraudulent and void.
