When we bought our home in 2015, the neighbor's chain link fence did not follow the property line, and about 16 square feet of his property was on our side of the fence, which we did not know when we bought our house. The 16 square feet allowed access to a gate which straddled both properties. Our neighbor recently demanded access to this fenced-off part of his yard, so we paid to have the fence and gate moved to give him access. Now he's threatening in writing to put a lien on our property because he doesn't approve of the manner in which we moved the fence and wants us to pay for added improvements on his side of the property line. We'd like to discuss our rights since we are currently under contract to sell our property. Thank you!
A lienor is any entity that furnishes labor, services, or materials to improve a property pursuant to a contract with the owner of that property wherein the owner consented to the improvements being made in exchange for payment. Based on the example you've given, it does not seem that your neighbord has construction lien rights on your property.
