General contractor is requiring supplier lien waivers before releasing payment to us, their subcontractor. Our supplier provide a lien waiver but not on the form that general contractor supplied to us. The general contractor rejected it and said it had to be on their form. The supplier is not willing to provide the lien waiver on the general contractor's form. So the general contractor is withholding payment and there is nothing we can do to meet their requirements to release it.
