Proof of ownership; when someone demands you remove a prefix

Yes, absolutely go with the RIR.  Only thing I might adjust it whether I let the customer launch a dispute with the RIR before or after I make the change and to me that would depend on the preponderance of the evidence either way.  I might give the long term customer the reasonable doubt.  A new customer with a new advertisement not so much.  Talk to your legal people of course but I would think if the RIR could verify a dispute in progress, you are covered until the dispute is resolved.  Seems legally reasonable to me and shows due diligence on your part without you getting in the middle.
