Pursuant to Article 81 of the 2014 Law on Marriage and Family, it is stipulated as follows:
Child care, upbringing, and education after divorce
1. After divorce, parents still have the rights and obligations to look after, care for, raise and educate minor children, adult children who have lost civil act capacity or are unable to work and have no property to support themselves according to the provisions of this Law, the Civil Code and other relevant laws.
2. Husband and wife agree on the person who directly raises the child, the obligations and rights of each party after divorce towards the child; in case of failure to reach an agreement, the Court shall decide to assign the child to one party for direct raising based on the child's interests in all aspects; if the child is 7 years old or older, the child's wishes must be considered.
3. Children under 36 months of age are entrusted to the mother for direct care, except in cases where the mother is not qualified to directly look after, care for, raise and educate the child or the parents have another agreement in accordance with the child's interests.
According to the above regulations, after divorce, if the child is under 36 months old (under 3 years old), he/she will be given to the mother for direct raising, unless the mother is not qualified to directly raise the child or the parents have another agreement suitable for the child's interests.
If the child is over 36 months (over 3 years old) but under 7 years old, it depends on the agreement of both parties. If no agreement is reached, the Court will decide who is suitable for the child's development in all aspects and will give custody to that person.
If the child is 7 years old or older, his/her wishes will be considered.

Pursuant to Clause 3, Article 82 of the 2014 Law on Marriage and Family, there are provisions on the obligations and rights of parents who do not directly raise their children after divorce as follows:
Obligations and rights of parents who do not directly raise their children after divorce
1. Parents who do not directly raise their children have the obligation to respect the child's right to live with the person who directly raises them.
2. Parents who do not directly raise their children have the obligation to support them.
3. After divorce, the person who does not directly raise the child has the right and obligation to visit the child without being hindered by anyone.
