Changing inetnum objects

Question:

can one company foo.com request its LIR to change the company's inetnum
(netname, description, tech-c) so it appears to belong to another company
bar.com?
If yes: who should this request come from (the original requester?
management?)?
If no:  what if foo.com is somehow related to bar.com (e.g. foo.com is a
parent or daughter of bar.com)? Suppose bar.com has taken over the internet
activities from foo.com?

Is there a document describing procedure to follow in such cases?
