Can an 18year old and a 15 year old get married?

Absolutely not. Wait until he/she turns 18 too than i guess it would be okay to get married because the both of you are at the legal age to get married. But at the end i think you guys should finish school and get a career first because getting married too earlier, well, you can ruin your life and if she gets pregnant good luck taking care of it because you actually need a job and money to raise it HA.
