How would you get papers on a purebred border collie whose mother was registered but father wasn't?

If your puppy was from a good breeder they should have some information, but if they dont have any registration for the father you can always go your council and ask them what things should be done, if that does not work THEN BAD LUCK alright?? maybe next time you should know what sort of breeder you are working with??!! good idea huh?
