I have been going out with my boy friend for about 4 months now.HE is 21 and I am 16,we have not done anything sexual.My mother does not agree with us seeing each other she was saying about going to call the cops and take him to court for statutory rape is that possible?

Yes. It is possible. It is a parents legal right and responsibility to contact police and file a report if they believe their minor child is being put at risk by another person. In this situation, it is a crime in the state of California for a 21 year old to have sexual contact with a 16 year old minor. If sexual contact is suspected, a parent or any person can report it to police at any time.

A parent doesn't actually take anyone to criminal court to press charges. Only the California prosecuting attorney can make the decision to file charges against an offender and seek a conviction. This decision is generally based on the findings of an investigation after a parent files a report/complaint with police. A parent has no control over what actions the District Attorney takes once a report is filed.
