Hello, all you need is their Godaddy Email or Account Number and Username. Then go to your godaddy user panel (domain manager) click- "My domains" unlock it, then check the name you are pushing and then click- "account change" Fill in the information click- next, confirm and your done. (One simple Note-- while filling out the account change it's easier to check the cirlce title Do not change. That only means that the receiver will have to fill out the appropriate contact info unless they give it to you and request you to fill it out. It's just quicker for you that's all.)
Take care...
