In Florida can a 17-year-old marry a 20-year-old without parental consent if she is pregnant?

Answer 1

Not in Florida, but you could go to Maryland to get married.

Answer 2

No, not in Florida.  If you are the father, you 2 can take a trip to Georgia to get married.  Make sure you have all the paper worked needed and schedule an appointment with an official in Georgia that can marry you before you 2 take the trip. Side note, the only other state besides Georgia that would allow this without court approval and without parental consent is Maryland.
