I'm a small upstart Landscaping company i completed a job client made initial payment after job completion. Client is now refuing to pay the rest of owed money.
Ohio rules on this are weird. You can file a lien so long as the landscaping is "the enhancement or embellishment of real property by seeding, sodding, or the planting thereon of any shrubs, trees, plants, vines, small fruits, flowers, or nursery stock of any kind."
Regular lawnmowing would not be sufficent, and you would just have to sue.
