When the couple divorce, if the child has grown up, the court only needs to make a decision on divorce and deal with the division of property, instead of dealing with the child.
 According to Chinese laws, natural persons over the age of 18 are adults. Adults are persons with full capacity for civil conduct and can independently carry out civil legal acts.
 [Legal Basis]
 Article 1084 of the Civil Code states that the relationship between parents and children shall not be eliminated by parents' divorce. After divorce, whether the children are directly raised by the father or the mother, they are still children of both parents. After divorce, parents still have the right and obligation to support, educate and protect their children. After divorce, children under the age of two shall be directly supported by their mothers in principle. If both parents fail to reach an agreement on the upbringing of a child who has reached the age of two, the people's court shall make a judgment on the basis of the specific circumstances of both parties and the principle that it is most beneficial to the minor children. If a child has reached the age of eight, his or her true wishes shall be respected.
