If, before final subdivision approval has been granted, any person transfers or sells or agrees to transfer or sell, except pursuant to an agreement expressly conditioned on final subdivision approval, as owner or agent, any land which forms a part of a subdivision for which approval is required by the chapter, such person shall be subject to a penalty not to exceed $1,000 and each lot deposition so made may be deemed a separate violation.

In addition to the foregoing, the municipality may institute and maintain a civil action for injunctive relief and to set aside and invalidate any conveyance made pursuant to such a contract of sale if a certificate of compliance has not been issued. Any such action must be brought within two years after the date of the recording of the instrument of transfer, sale, or conveyance of the land, or within six years if unrecorded.
