It depends on your relationship with your ex-wife. Do you trust her?
It depends what she is going to do overseas.
If she is going on holiday, there is probably no reason to stop her.
If she is going to her country of origin, you might reasonably get worried that she will stay, and not return.
Look for two important issues. The country she visits should have signed the Hague Convention, which is an international convention to prevent (among other things) ex-spouses kidnapping children. And she should preferably not have any rights to stay on in that country (especially if she has foreign citizenship and is returning home)
