How do divorced children need the other half to study in Hong Kong?

For children of divorced families, although the marriage relationship between parents is dissolved, the guardianship relationship between parents for minor children remains unchanged.

If the parent who is raising the child wants to take the child to study abroad, the country of studying abroad usually needs the consent of the parent who is not directly raising the child, and after obtaining the consent of the other parent, the child can go through the formalities of studying abroad by signing a consent statement and notarization.
