If you have sole custody of your 2 children for 10 years can your ex husband gain temporary custody while your children are visiting?

Yes, your ex-husband can gain temporary custody while the children are visiting, but it typically requires consent from you or a court order. If there is a custody agreement in place, it may outline the conditions under which he can have the children. Additionally, if he petitions the court for temporary custody, the judge will consider the best interests of the children before making a decision. Always consult a legal professional for advice specific to your situation.
