Sorry, thought it might help to know the background of the situation. Basically he has full custody but the kids have been living with me full time since September 1st and they will be living with me from now on. I've talked to an attorney and he said that the only way custody can be changed is if there are major changes. I figured the kids living with me full time would be a major change but at the time I talked to the attorney the kids were with me more than half of the time and apparently that didn't matter. At this time he's still living in a 4 bedroom house but he's planning to move to a 1 bedroom apartment next month. Would it be better to wait until then? I have a feeling if he finds out I'm doing this that he will keep his current house or find another house for him and the kids. I figured it would look better for me if he was living in a small place where he obviously didn't plan to have the kids.
