It's a business trip, and the owner is going with him. They'll probably charge everything and then find a way to write it off as a business expense.
Any time I ask him to send some money my way when it's his visitation time and he needs me to take the kids, he says he has no cash or his checkbook on him. We have a 50/50 split and he doesn't pay child support, so I feel justified in asking for money in these circumstances. It's not like I'm getting child support and then asking for more money on top of it.
My lawyer doesn't want me talking to him about anything that doesn't involve the kids, unless I can state it in 5 words or less. Right after he said he'd send what he could, he goes "I have to get back inside now." Yeah, can't have his girlfriend seeing him talking to me in a calm fashion.
