Mirasolo, 27, was convicted of the sex attack nine years ago, but has now proved his paternity in court in Michigan.
The Judge awarded parenting rights and joint legal custody to Mirasolo and gave the attacker his victim's home address.
But, according to court documents, Mirasolo was not the one who initiated the case, and has no plans to invoke his parental rights.
According to Rebecca Kiessling, who is representing the victim, the sentence for Mirasolo's crime of rape of a minor should have been at least 25 years behind bars, but he only served a few months, because it was judged as 'attempted' rape, though the victim was pregnant.
In a statement, Ms Kiessling said, 'Objections and a motion will be filed on behalf of the rape victim mother...This case is believed to be the first of its kind in Michigan, and perhaps in the US, in which a rape victim will seek protection under the new Rape Survivor Child Custody Act and proves why rape conviction should not be required.'
In a comment on Facebook, Ms Kiessling added that she thought the victim was 'screwed over' because she was told not to press first degree charges, despite being pregnant.
