Idaho only recognized common law marriages that were already in existence before January 1, 1996. Therefore unless your friend's ex, had begun living with his second wife on or before December 31, 1990, the relationship he had while still married to you friend. I do not think you have a case of bigamy here. And even if you did it is a criminal charge not a civil open. Adultery sounds a bit more like what was going on with your friend's ex, but it would be of no benefit to you friend to seek adultery charges. Idaho is a no-fault divorce state, which essentially means "irreconcilable differences" is all that is required to petition for dissolution.
