Good question. If you never signed a written agreement with respect to the road maintenance agreement that you are writing about and the agreement is not recorded on your property, you are not bound by it as a signatory or as an owner taking subject to the agreement when you bought the property you have.However, if you have paid on this road agreement in the past, an argument could be made that your past conduct would obligate you to pay in the future with respect to this road agreement.Legally, you are not bound to this road agreement by any signed document or recorded document.
