If a 16 year old got pregnant by a 23 year old, can the state or parents press charges?

Consensual sex between two people is legal in Michigan provided that both parties are 16 or over. Photos or videos of nudity or sex require that the people be 18 or over. If it is unclear that the mother was over or under 16, there is a chance you could be prosecuted, but they would have to prove that she was under 16 to have a case. You may still have an obligation for child support. The only rules regarding age gap apply only if one of the parties is under 16.

16 is the age of consent in Michigan no matter how much older the other partner is, so if all sex acts happened at age 16 or after, there is no criminal liability even if the partner is 99 years old, (unless there is a special relationship, like teacher/student for example).
