Is it legal for a parent to consent for a minor.to have sex with another minor?
I spoke with my 14 year old daughter today and she advised me she is having sex with a 16 year old boy here in missouri . I called her MOTHER over to my house and was speaking with her over the situation and she knowingly agrees and let’s this happen. Is all this legal?

Given that sex between the two children is legal, I cannot think of any law that it violates. I could not find an applicable “Contributing to the Delinquency” charge. You are free to call the police if you disagree.

It may be that family court is the best solution to your problem: if you feel that not having sex is in your daughter’s best interest, you can petition the court for an order prohibiting her mother from allowing it in her home. Of course, then your daughter would just have sex outside the home, which actually sounds less safe.
