We financed a water purification system in 05/16/2016. The work was completed on that same day. We had some financial issues and had to file for a Chapter 7. We obtained counsel in 12/2016 and this company that financed our water purification system was included in the filing. Our discharge was 10/04/2019. We placed our home for sale and closing was going to be later today, 04/29/2019. The title company notified us on Friday 04/26/2019, of a 2nd mortgage listed on the title settlement statement from a 3rd party biller. We were shocked and had no idea about any such 2nd mortgage. We found out yesterday, 04/28/2019, through a Osceola Co. Florida e record search, the company that had financed the water purification system filed a mechanics lien/UCC Financing Statement with Osceola Co. Florida on 01/05/2017. This was 6 months after the completion of the system install and just after we obtained counsel for our bankruptcy. They were included in our filing and discharge. We have and had not received any notice of this UCC action from Aqua Finance or their 3rd party biller Quantum 3 Group, LLC. Can they legally do this and are we obligated to pay this to close on our home sale?
