This is one of the main issues that the court uses to determine whether to allow infidelity to affect its rulings on alimony and property division.
In cases where infidelity affects a property ruling, it is because the cheating partner spent marital money on his or her affair partner. If the court can prove that he or she took from the couple’s joint finances to pay for dates and gifts, it may rule that the innocent partner is entitled to a greater share of the couple’s assets to make up for the loss of this money.
