Legal Question in Criminal Law in Michigan

There are a few issues to consider when addressing this question. For grammatical ease I'll assume the 21-year-old is the male and the 14-year-old is the female. Legally, it doesn't matter which one is the male and which is the female.

First, the answer depends on what you mean by "relationship." I'll assume from the wording of the question that we're talking about an unmarried couple having intercourse. Under these circumstances the answer is - yes, he can be charged with 4th degree criminal sexual conduct. It is considered a "strict liability" crime, which means it doesn't matter if he thought she was of age, if she consented, or if her parents consented. If the police find evidence of this relationship, he can be prosecuted.

Second, each act of intercourse is considered a separate crime with a 10-year statute of limitations. He wouldn't be entirely off the hook until 10 years from the last act of intercourse. In other words, he can't be charged for any acts of intercourse that occurred at least 10 years ago or more, but he can still be charged for every act of intercourse that occurred less than 10 years ago. From the above facts, he still has five more years to go before he can breath a sigh of relief.

You can consult with an attorney for some peace of mind, but until he is charged with a crime there is not much he can do.

Good luck.
