Below 16 you need legal guardian's consent as well as the courts. Now your parents might be OK with it but I doubt the court would be. Marriage means more than just being allowed to marry, it also means you are emancipated. Just being in love or even have children (the 20yo would be charged with statutory rape in that case since age of consent is 18 with no close exemptions in Arizona) would not be good enough reason to let a minor age 14 to marry. You can ask your parents if they are willing to spend money on that but it would be smarter to wait until you are 16, or better yet 18.
