If there is a mutual easement concerning the subject that that you have written about where your parcel and your neighbor's parcel have reciprocal right of way easements over the portion of each other's property for ingress and egress, you need to carefully read the terms and conditions of the written easement in that its terms and conditions control any and all obligations concerning repairs and maintenance (assuming such is mentioned in the document) in the absence of conflicting state law.If there is no mention of maintenance and repairs in the written easement, under common law in all states, the person who holds the easement has the obligation to maintain it in good condition as well as repair it. If the other neighbor having use of it refuses to pay his or her half of the maintenance and repair for it, you have an equitable lien on his or her property for the portion in excess that you pay with accrued interest running from the date of sale.
