Legal Question in Family Law in California

You don't say what your current custody arrangment is, but it seems it is shared custody of some kind. Therefore you cannot move without his consent or a court order modifying the custody order. You have stated basic facts that would constitute a "change of circumstances" allowing for review and modification of the existing order, but you have to go through channels as they say. If he won't agree to a modified custody arrangment that would accomodate your move, then you have to get court permission. Also, a 14 year old does not get to choose where to live. Their preferences are merely one of a number of factors the court must consider in finding and ordering a custody plan that is "in the best interests of the minor child."
