Hi Carolyn, I'll answer your questions in part and will get back with greater details when I'm in the office tomorrow and can check the lawbooks. Fornication would not necessarily be adultery as it can be an offense committed with a spouse. It is sometimes referred to as an unnatural act but has included acts which we now would consider natural. Specific acts included depend on the jurisdiction. It is not rape. It could be charged along with adultery or rape as a lesser offense but is separate and distinct from both. It may be different acts with different fact situations. Hope this helps but I'll get back with more detailed information. Best regards and Merry Christmas, Jim Whitney
