If I am under the age of 16 and want to get marry with my boyfriend in Georgia what can I do

How old is your boyfriend?

He is 20 :/

Absolutely nothing! GA law states that a marriage license can't be issued for anyone under 16.

Also the age of consent in GA is 16 and since your boyfriend is more than 4 years older than you, he can be put away for a long time.

Frankly, any 20 yr old that has a romantic relationship with a 15 yr old (or less), is a predator and you should run from him. Do your parents know he is your boyfriend?
