My understanding of community property is that while each of you technically owns 50/50, if you divorce it doesn't have to be divided that way. If the divorce is civil, and the two of you agree on terms, then you can divorce any way you want. If the divorce is not civil, you both have lawyers, then you end up fighting over how to split the dog 50/50.
Hopefully it is a civil divorce, and you can sit down with your soon to be ex and hash out terms that you both feel are fair. Maybe you end up with 48% of the assets and she gets 52%, but you are happier because you were able to get the items you wanted and were able to walk away without it become hostile.
Once you have decided on how you want to split your assets, then I would still pay a lawyer to help draw up the proper paperwork so you know it is done right and doesn't come back to haunt you later on.
Good luck with this, divorce is never easy, but hopefully yours goes as smoothly as possible.
