Thanks for your question! I am working on your answer. This service is for information only. I cannot give you legal advice. Please stand by!
It is highly unlikely that you would lose custody of your children over this. Unless the neighborhood is full of meth dealers, I don't see a Judge preventing you from moving because one person made a bad decision. If it was only one meth house and it's been shut down and the person imprisoned, your ex is probably out of luck.
Then I don't think that it should be an issue. While anything is possible in family court, I don't think a Judge tell you that you can't move there. And if the Judge did tell you that you couldn't move there, that wouldn't mean losing your children, that would just mean you couldn't move there.
The court looks at the best interest of the children. So if the Judge were to find somehow that it was not in your children's best interest to live there, the Judge could tell you that you could not take the children with you when you moved. It's not up to your ex, it's up to the Judge.
