We bought a home three years ago. The deed included a statement "this property has a shared well with next lot." The pump house and well is on our property and connected to our electrical meter. The neighbors said they'd paid the previous owners $15 a month and we agreed on that amount until we researched it further. I have years of documentation of them not paying us on time for their water per our agreements and a letter from them refusing to pay our requested $20 a month after the electricity went up significantly. They haven't paid us in five months now. I have requested payment in writing several times and have asked them to meet with us to create a shared well agreement, which they will not. Do I have any recourse? Can I shut their water off legally without an agreement?
