I am not familiar with any Standard requiring "cosigning." In nearly 40 years of dealing with Quality Systems, I have seen
some paperwork processes which called for redundant signatures.
The process of "document approval" for new or revised documents may be what your customer refers to. We may have a translation issue when you speak of "forms" - most forms are merely data entry sheets and may be frequently modified for typography, letterhead, etc., but the data to be entered remains the same whether the data entry box is at the top or bottom of the page. Such minor changes may be left for only one person to change and approve, BUT the change must be communicated to EVERY person concerned and decision made whether to continue using old forms until they are used up or to withdraw old forms and issue the new ones.
I have some suspicions about the reason for the customer's request. I suspect there have been some instances of nonconformance or mixed use of old and new forms because the change was not communicated to everyone and old forms not withdrawn.
Alternately, if we are talking about documents other than data entry forms, a product or service could have been made to the old document instead of the new one. You indicate a relatively small organization. The customer may feel there is a high probablity one of the two cosigners would catch a mistaken use of wrong document.
Will you please tell us the circumstances surrounding customer' request?
