An owner or agent of an owner of land located in a subdivision may not transfer or sell land by reference to, exhibition of, or other use of a plat of a subdivision before the plat has been: approved by the county planning board; and recorded in the office of the clerk of the circuit court of the county in which the property is located. A person who violates this subsection is subject to a penalty of $100 for each lot or parcel transferred or sold in violation to be paid to the district council. The description of a lot or parcel by metes and bounds in the instrument of transfer or other document used in the process of transferring or selling does not exempt the transaction from the penalties or remedies provided in this section. The district council may: enjoin the transfer, sale, or agreement in any circuit court; or recover the penalty by civil action in any court of competent jurisdiction.

The clerk of the circuit court of Montgomery County or Prince George’s County may not record a subdivision plat in the regional district unless the plat has been endorsed in writing by the county planning board. A plat is invalid if it is recorded without being endorsed by the county planning board. The Commission may institute proceedings against the clerk of the circuit court of Montgomery County or Prince George’s County to compel the clerk to strike from the county land records a subdivision plat that is recorded but not approved in accordance with subsection (a) of this section. A court of competent jurisdiction may issue appropriate orders for purposes of this section.
