Hi,
My current control right now, is to issue a Corrective Action Report for incorrect form used.
Does it make sense? Or it is an overkill among ourselves.

Well, maybe. That is not really doc "control," that is reaction to document failure. It might be a good idea in some cases, but maybe not in every case.
Corrective action is a tool to
discover the cause of failure, and the solutions to eliminate those causes. It is sometimes used as a punisher or disincentive. That is a secondary purpose, not the primary.
It should also be applied appropriately to the level of failure or signiificance of risk involved.
If I have a breakdown in doc control, or the source of incorrect docs is not know, or there are repeated failures, intentional disregard for procedures...those are cases where I would suggest writing a CA would be beneficial. But, not to punish the culprit, but to investigate and document causes, motives, competencies, weaknesses, unnecesarily complicated methods, so that we can make solutions to those causes.
Doc control can be pretty easy and simple, if done right. I find people don't want to violate doc control as a principle. They don't want to intentionally use wrong documents. They develop shortcuts when the "proper way" seems too clunky or gets in their way of trying to do their jobs.
If controlling docs is a support process (supplier) to those who use the docs, then keep the user of the docs (internal customer) in mind when creating the rules. If the right way is also the easiest way, chances are they will follow the rules. Thus, knowing the true root cause (or motive in this case), will help you eliminate the root causes.
