I'm not a lawyer and have never been divorced either, but I would agree with the others that say to kinda lay low about the miles until everything is is worked out. If you try to make an issue of the miles right away, then she may figure out that you want them and want to split them just because you want them. If you lay low about them for now, maybe she'll take her share first and the miles will never even be an issue. Of course, it would be better to ask your attorney.
