Is there a law, or should there be a law, to jail a spouse for wrongfully accusing the other spouse of molesting their child?

I know women that have wrongfully accused their husband (while going through a divorce) of molesting their child. I think these women if found guilty of making it up, should go to jail with a stiff sentence. I have gone to many events and have heard women talking about doing this to get the husband in trouble out of sheer hate.
