I haven't had the custody issue (yet anyway), but I still document religiously as well. I write down when he's supposed to come, when he comes, how long their gone (or he's here), when he shows up to the kids' events, etc. If I know I document when they talk to their dad on the phone, as well. I document when he has initiated it and when the kids have initiated it. I write down what the kids tell me, what I see, and behaviors the kids exhibit. I document phone conversations we have and save e-mails as well. If I made $1/minute on documentation, I wouldn't have to file for bankruptcy. It takes a lot of time, but it's well worth it. And, I KNOW Jerk is no where near organized enough to have documentation of any of this...
