The Betrothal Law, and the lack of it in the sequel?

Okay, so this has been bugging the absolute heck out of me. Simba and Nala were betrothed to each other in the first movie as very young cubs, possibly from birth even. But in Simba's Pride, it's never mentioned whether or not Kiara is betrothed to somebody or not. Obviously Kovu is going to be her mate but what was Simba's plan before he came into the picture? Was she betrothed to some lion in another pride, did Simba get rid of the law like he said he was going to in the first film, are they still in the process of choosing suitors? I realize that the underlying reason is most likely that the creators just didn't have time to add that little detail in but that's boring and I want to know what people think was the deal during the events of the film.
