Basically you are buying a player registration with Fifa, so if a team wants a player they have to purchase the registration with the relevant authorities. Loaning players is just an agreement between the clubs and the central authorities that the registration will be loaned for an agreed amount of time. This can come with clauses that a player must play a certain amount of games, can't play against a parent club etc and the loaner must pay a fee or contribution to wages.
