AL, why not just tell her you won't be driving a U-Haul 1200 miles across the country, therefore, she needs to take the 2nd dog. Don't ASK, but TELL.

I think u r getting the better end of this deal. A chain smoking lazy W isn't a good partner for a working H.

As for her moving....that s/b her issue. As for her using your attorney, she isn't. She is merely agreeing to your terms. So if and when she balks.....tell your attorney NOT to do her bidding. You are the one paying for the Attorney's time.

You move your stuff and your dog(s). I feel bad for the dogs. I don't feel bad for her moving nor for her dad (they deserve each other at this point). RE: Whether her dad is a good person or not, he is allowing this woman to use him as she has used you. Not a smart decision even if she is his kin.

If you help her move, she will have more to talk about. The less you do and say with her, for her and to her, the better. Remember this is her decision. She needs to own the consequences.

I suspect once she figures her $$ tree isn't in the U-haul..... she may try to butter you up.

Best you be far away by then.

JMHO,
L.
