There are three kinds of copies of "divorce papers". A copy your lawyer gave you, a certified copy from the court or state records, and a photocopy of a certified copy. Any of the three can confuse certain individuals. I was adding to what you said, not correcting you.
For my latest divorce, the court requested me to provide four originals. On the spot, the judge signed all four. The court kept one and the clerks certified the other three to give to me. It can be done any way the local court decides to do it. If a person doesn't know the difference, there's room for error.
