I solicited a contractor in Mississippi to paint the interior and exterior of a vacant rental property . The contractor emailed me an estimate that we later discussed and verbally settled on a negotiated lower price. However, the initial contract or the revised contract, was ever signed and the contractor did not show up the day the work was to commence so I assumed because I did not sign and return the contract the contractor had not expected to do the work quoted. A couple days later the contractor showed up at the vacant property to begin working. I didn’t know the contractor had begun the work for a couple days because the property was vacant. The contractor completed the work on 10/28 and filed a lien on 1/29. I understand this may be outside of the 90-day filing guidelines, but I would like to verify if a pre-lien notice is required and how do I challenge a notice of a special lien.
