yes and no i live in nevada and i live 6 hrs from vegas even if you wanted to marry someone in nevada in vegas you have to have at least a parent /guardian present at the time of marriage if your under 18 as for the laws of other states or cities once Your married Your legally married there's nothing like if you get married in vegas and go back to your state or town that they can strip you of your marriage unless it has other things surrounding it like running away with a guy that's 18 and your 15-16 and getting married in vegas then maybe but as i said you have to have a parent or guardian present so with out that your screwed unless by some chance you find a vegas chapel that dose not care then your married but going back to your town or state u might run into problems....that's all i know
