I can't speak to the laws in your state, but I know of several cases in NY where sales of animals were forced by a bitter divorce. Not just snakes, but dogs and birds...they're viewed as property, with a value; and the options were to divide them, or sell them and divide the money.
I agree with Harald. I, too, live in NY, and since it's a community property state, it could be that you might lose some of the snakes, but if you know of things in the home that she cherishes, and that have been accumulated during the marriage (NOT as gifts (from you or anyone else) or any family heirlooms from her side), you may be able to negotiate. They have to be things you and she purchased during the course of the marriage.
Tell her she can have the china cabinet (or whatever) and you get the snakes. Otherwise, YOU will fight her for the cabinet and it's contents.
Are you willing to give her the wide-screen TV?? Does she even want it??
How about Fluffy, the 45 pound cat that coughs up fur-balls the size of grapefruits??
The family portrait in the dining room???
The new microwave and Cuisinart??
The new Harley in the garage???
It has to be something SHE doesn't want to live without.
Tell her you want it all if she's going after your snakes, and she'll have to foot the bill for feeding and vetting them.
She's angry and vindictive right now, but when she realizes you're not going to fold like an origami crane, she'll rethink the snakes.
Do you have any dirt on her??
USE IT!! And tell her you'll make it public knowledge in the court records.
It's ALL about negotiation!!
Try to get that hammered out-ON PAPER WITH SIGNATURES AND NOTARIZED-before you hit the lawyers.
The only "civilized" divorces are in fairy tales.
