Ohio House Bill 479, signed by the Governor on December 20, 2012 and effective in March of 2013, has a provision that specifically protects contributions to 529 plans.
A new provision was added to Section 2329.66 of the Ohio Revised Code to protect contributions to a so-called 529 plan. Funds held in such a plan by any person who is domiciled in Ohio will be exempt from execution, garnishment, attachment or sale to satisfy a judgment.
