Ohio law does not require a seller to provide a right to cancel every contract. Below is a complete list of all cancellation rights under Ohio law.
Ohio Cancellation Rights:
• Door-to-Door Sales: Three Days. The Home Solicitation Sales Act gives
consumers three days to cancel sales made in their homes or at a place that is not
a company's regular place of business, such as a bridal fair or a home
improvement show.
• Credit and Debt Counseling Services: Three Days. Consumers have three days
to cancel credit and debt counseling services under the Ohio Credit Services
Organization Act.
• Prepaid Entertainment Contracts: Three Days. Prepaid entertainment
agreements only include contracts with health spas, dance studios, diet centers,
dating agencies and martial arts schools. The Prepaid Entertainment Contracts Act
does not include all kinds of prepaid contracts, such as prepaid tanning salon
sessions, prepaid plans at laser tag or paint ball facilities and prepaid plans for
ring tones or other cell phone services.
• Home Equity Loans or Mortgage Refinancing: Three Days. The federal Truth
in Lending Act gives consumers three days to cancel a home equity loan or a
mortgage refinancing.
• Business Opportunity Plans: Five Days. Under the Business Opportunity
Purchaser's Protection Act (O.R.C. Section 1334.01 et seq.), consumers have five
days to cancel a business opportunity agreement, in which a buyer pays a seller
for the rights to offer, sell or distribute goods or services.
• Hearing Aids: Thirty Days. Under the Hearing Aid Returns Act (O.R.C.
1345.30), consumers have the right to return a hearing aid for any reason within
30 days after it is originally delivered.
• Telemarketing Sales: Under the Telephone Solicitation Sales Act (O.R.C.
4719.01 et seq.), consumers have the right to cancel a purchase until they sign a
written agreement confirming the sale.
• Car Purchase: Ohio law does NOT give consumers the right to cancel a car
purchase.
