Can a 15 year old decide which parent to live with in Nevada?

Answer 1

No, however the child is always free to make their wishes known to the judge, either in court when custody is being decided, by requesting a meeting with the judge, writing a letter to the judge expressing their wishes, or engaging an attorney or guardian ad litem to speak for them. The judge will take into consideration the wishes of the child, and generally, the older the child, the more weight is given to those wishes.

Ultimately, however, the judge will rule depending on what he or she feels would be in the best interests of the child.
