Filial support laws were an outgrowth of the Elizabethan Poor Law of 1601.
At one time, as many as 45 U.S. states had statutes obligating an adult child to care for his or her parents. Some states repealed their filial support laws after Medicaid took a greater role in providing relief to elderly patients without means. Other states did not, and a large number of filial support laws remain dormant on the books.
Generally, the media has not covered filial responsibility laws much, and there has not been the political will to see that they are enforced. As of 2012, twenty-nine states have such laws on the books, and a few states require the potential support of grandparents or even siblings.
