On what grounds would you have a restraing order issued?
Sorry, but all you can do is lock her away until she's 18 then she's free to do what she wants.
At this point it's only AFTER the fact that you can do anything. And that would be statutory rape charges. But, although this isn't a funny issue, I had to laugh at the mississippi statutes and how they addressed statutory rape.
Section 97-3-67
Any person who shall have carnal knowledge of an unmarried person of previously chaste character younger than himself or herself and over fourteen (14) and under eighteen (18) years of age, upon conviction, shall be punished either by a fine not exceeding Five Hundred Dollars ($500), or by imprisonment in the county jail not longer than six (6) months, or by both such fine and imprisonment or by imprisonment in the penitentiary not exceeding five (5) years; and such punishment, within said limitation, shall be fixed by the jury trying the case, or by the court upon the entry of a plea of guilty.
And especially the following:
Section 97-3-69
In the trial of all cases under the last preceding section, it shall be presumed that the female was previously of chaste character, and the burden shall be upon the defendant to show that she was not; but no person shall be convicted upon the uncorroborated testimony of the injured female.
However, this statute is in direct opposition to the age of consent statute which gives children at the age of 16 the right to consent to sex.
And to further complicate the matter, the age of consent statutes states: If the female is over 12, the status applies only to virgins.
You need to move into the 21st century.
