The main reason for doing this is to ensure the exhibits are benched with yours.
When I have done this I have put the owners name and underneath on the second line have put handled by and my name, but the owners address and signature is needed.
As to whether it will appear properly in the catalogue or results is anyones gues, as last year one freind was showing another friends dog and they kept listing the handler qas owner which made it look as if the exhibit had been sold on. :(
