In 2011, China became the first country to pass national legislation legally obligating adult children to visit their elderly parents. There are no set parameters for how often children must visit, but parents in China who do not feel sufficiently cared for have legal grounds to sue their adult children. This law was put into place as a result of more adult children moving away from their parents and into bigger cities, which was thought to contribute to rising levels of the elderly being neglected or abused. Although a legal obligation for visitation is not common worldwide, adult children might be required to pay for their elderly parents’ expenses. For example, in the United States, 30 states have laws that make adult children legally responsible for their elderly parents' necessities, such as food, shelter and medical care, but those laws are rarely enforced.
