Postdating an instrument will not destroy its negotiability.

Postdating an instrument refers to the practice of writing a future date on the instrument, and it does not affect its negotiability. The negotiability of an instrument is determined by its adherence to certain criteria outlined in the Uniform Commercial Code (UCC), such as being an unconditional promise or order to pay a fixed amount of money. The date written on the instrument does not alter these fundamental characteristics.
