Who are the persons precluded to set up the defense of forgery?

Persons precluded from setting up the defense of forgery typically include those who have engaged in the act themselves, as well as individuals who are complicit or have conspired with the forger. Additionally, individuals who have a vested interest in the forged document or have benefited from it may be barred from claiming forgery as a defense. Lastly, parties that have acted in bad faith or with negligence in relation to the authenticity of the document may also be precluded.
