why is she paying a lease on a car that her partner uses and who was paying that lease before she turned up? Lie after lie. It doesn't make sense which is how you know it's a lie.
When my XGF moved in, she paid more rent than I requested The point was to maintain her outgoing expenses, since those numbers factor into predetermined alimony and child support calculations. If she's lying, trust your lawyer to reveal it. If she's just trying to maximize what she gets in the divorce, expect your lawyer to do the same. That's how the process works. In the end, it finds a balance.
