Not to mention, make sure you've bred the animal enough times to have really covered your bases in proving it out AND make sure you have pictures of ALL the breedings in your collection, AND find a judge who is actually going to be able to differentiate between the snake you're saying was supposed to be a het, and whatever other normal ball pythons you have. My wife sees these things everyday and can't tell the normals apart, and I would be willing to bet that any judge this case happens to land in front of, will not be so well versed in ball pythons. And even if it did go to court, and you did win, in theory, all that could happen is a judgement placed against the defendant...and I've seen plenty of people never see a dime from those judgements....all in all, good luck, and buy from reputable breeders.
