(a) Any assessment of benefits or any installment thereof, not paid within thirty days after the due date, shall be delinquent and shall be subject to interest from such due date at the interest rate and in the manner provided by the general statutes for delinquent property taxes. Each addition of interest shall be collectible as a part of such assessment.

(b) Whenever any installment of an assessment becomes delinquent, the interest on such delinquent installment shall be as provided in subsection (a) of this section or five dollars, whichever is greater. Any unpaid assessment and any interest due thereon shall constitute a lien upon the real estate against which the assessment was levied from the date of such levy. Each such lien may be continued, recorded and released in the manner provided by the general statutes for continuing, recording and releasing property tax liens. Each such lien shall take precedence over all other liens and encumbrances except taxes and may be enforced in the same manner as property tax liens. The tax collector of the municipality may collect such assessments in accordance with any mandatory provision of the general statutes for the collection of property taxes and the municipality may recover any such assessment in a civil action against any person liable therefor.

(c) Any municipality, by resolution of its legislative body, may assign, for consideration, any and all liens filed by the tax collector to secure unpaid sewer assessments as provided under the provisions of this chapter. The consideration received by the municipality shall be negotiated between the municipality and the assignee.

(d) The assignee or assignees of such liens shall have and possess the same powers and rights at law or in equity as such municipality and municipality’s tax collector would have had if the lien had not been assigned with regard to the precedence and priority of such lien, the accrual of interest and the fees and expenses of collection, except that any such assignee (1) shall not be insulated from liability by virtue of the provisions of § 42-110c, and (2) shall be obligated to provide a payoff statement, as defined in § 49-8a, in the same manner as a mortgagee in accordance with the requirements of § 49-10a. The assignee shall have the same rights to enforce such liens as any private party holding a lien on real property, including, but not limited to, foreclosure and a suit on the debt.

(e) No such assignment executed on or after July 1, 2022, shall be valid or enforceable unless memorialized in a contract executed by the authority and the assignee that is in writing and provides: (1) The manner in which the assignee will provide to the owner of the real property that is the subject of the assignment one or more addresses and telephone numbers that may be used for correspondence with the assignee about the debt and payment thereof; (2) the earliest and latest dates by which the assignee shall commence any foreclosure or suit on the debt or the manner for determining such dates, except as may be impacted by any payment arrangement, bankruptcy petition or other circumstance, provided in no event shall the assignee commence a foreclosure suit before one year has elapsed since the assignee’s purchase of the lien; (3) the structure and rates of attorney’s fees that the assignee may claim against the owner or owners of such real property in any foreclosure, suit on the debt or otherwise, and a prohibition from using as foreclosure counsel any attorney or law office that is owned by, employs or contracts with any person having an interest in such assignee; (4) confirmation that the owner of the real property for which the lien has been filed shall be a third-party beneficiary entitled to enforce the covenants and responsibilities of the assignee as contained in the contract; (5) a prohibition on the assignee assigning the lien without the municipality’s prior written consent; (6) the detail and frequency of reports provided to the municipality’s tax collector regarding the status of the assigned liens; (7) confirmation that the assignee is not ineligible, pursuant to § 31-57b, to be assigned the lien because of occupational safety and health law violations; (8) disclosure of (A) all resolved and pending arbitrations and litigation matters in which the assignee or any of its principals have been involved within the last ten years, except foreclosure actions involving liens purchased from or assigned by governmental entities, (B) all criminal proceedings that the assignee or any of its principals has ever been the subject, (C) any interest in the subject property held by the assignee or any of its principals, officers or agents, and (D) each instance in which the assignee or any of its principals was found to have violated any state or local ethics law, regulation, ordinance, code, policy or standard, or to have committed any other offense arising out of the submission of proposals or bids or the performance of work on public contract; and (9) such additional terms to which the municipality and the assignee mutually agree, consistent with applicable law.

(f) The assignee, or any subsequent assignee, shall provide written notice of an assignment, not later than sixty days after the date of such assignment, to the owner and any holder of a mortgage on the real property that is the subject of the assignment, provided such owner or holder is of record as of the date of such assignment. Such notice shall include information sufficient to identify (1) the property that is subject to the lien and in which the holder has an interest, (2) the name and addresses of the assignee, and (3) the amount of unpaid taxes, interest and fees being assigned relative to the subject property as of the date of the assignment.

(g) Not less than sixty days prior to commencing an action to foreclose a lien under this section, the assignee shall provide a written notice, by first-class mail, to the holders of all first or second security interests on the property subject to the lien that were recorded before the date the assessment of the lien sought to be enforced became delinquent. Such notice shall set forth: (1) The amount of unpaid debt owed to the assignee as of the date of the notice; (2) the amount of any attorney’s fees and costs incurred by the assignee in the enforcement of the lien as of the date of the notice; (3) a statement of the assignee’s intention to foreclose the lien if the amounts set forth pursuant to subdivisions (1) and (2) of this subsection are not paid to the assignee on or before sixty days after the date on which the notice is provided; (4) the assignee’s contact information, including, but not limited to, the assignee’s name, mailing address, telephone number and electronic mail address, if any; and (5) instructions concerning the acceptable means of making a payment on the amounts owed to the assignee as set forth pursuant to subdivisions (1) and (2) of this subsection. Any notice required under this subsection shall be effective upon the date such notice is provided.

(h) When providing the written notice required under subsection (g) of this section, the assignee may rely on the last recorded security interest of record in identifying the name and mailing address of the holder of such interest, unless the holder of such interest is the plaintiff in an action pending in Superior Court to enforce such interest, in which case the assignee shall provide the written notice to the attorney appearing on behalf of the plaintiff.

(i) Each aspect of a foreclosure, sale or other disposition under this section, including, but not limited to, the costs, attorney fees, method, advertising, time, date, place and terms, shall be commercially reasonable.
