Can I get a restraining order against my sons 18 year old girlfriend?

Yes you can get a restraining order against her...

Your 15 year old is a minor and she at 18 years old is an adult.

As a parent you have the legal right to keep her away from your minor child until he turns 18.

Take all your evidence to the court and file a petition for a restraining order, if she violates the restraining order she will be arrested and jailed.

If you son sneaks out to meet her then likewise he can also be brough to juvenile court for violating the restraining order..

The legal age of consent in Florida is 18, but the close in age exemptions are set to 16 years of age.

So since your son is only 15 then if you know or have a suspicion to believe that they have had sex or are having sex then you may wish to address the possible issue of filing a criminal complaint for statutory rape.

If this 18 year old girl still lives with her parents you may want to notify them of the possible legal actions if they dont help their daughter to obey the law.

She is an adult and he is a minor, I would call the police she is a predator.

Yes women can be predators too there has been a lot of cases one that I recall is the

teacher and the 14 year old boy she ended up in jail.

This is past the restraining order she has a hold over him and you need to also call

the district attorney's office if he was 17 you probably could just kick him to her house but in this case there is way too many years before he is an adult. He needs help and I would certainly get her arrested for it. And he needs professional counseling. You are the parent get to it!

Why are you on Y/A and not contacting your local authorities about this? Plus, you could have had his butt committed when he was put in the hospital and got a restraining order then. Again, why are you on here with your story without doing what seems needed.

Just chase her off your property with a samurai sword!
