If two or more municipalities have tax liens against any of such properties, they may join in the proceeding. Upon foreclosure in such a case, the court shall decree that each municipality has an undivided interest in such property in proportion to the amount due upon the tax lien or liens it has against it, plus any interest, lien fees and other charges which have accrued upon them since the bringing of the petition. In the event of such joinder, the entry fee, judgment fee and costs of publication shall be shared by the municipalities foreclosing in proportion to the amount of taxes, interest and other charges due each municipality. Any court costs, appraiser’s fees or attorney’s fees which are recovered in accordance with § 12-193, shall also be shared by the municipalities in proportion to the amount of taxes, interest and other charges due to each such municipality.
