Legal insecurity regarding land in the DRC stems partly from weak law enforcement and partly from a lack of awareness of legal mechanisms and customary practices to protect legally acquired land. In this context, our article aims to raise awareness among Congolese concessionaires and potential land buyers about the importance of legal and extra-legal techniques that allow for the peaceful enjoyment and protection of land and real estate, often targeted by malicious actors such as false claimants and land agents in the absence of adequate safeguards. Research findings reveal that in the city of Mbandaka, in particular, some individuals posing as rightful claimants—often in collusion with land affairs agents or certain political-administrative authorities—spread fear and unlawfully resell plots belonging to legitimate owners who failed to take preventive measures. Studies show that proper enforcement and respect for land legislation—which recognizes land titles, particularly the certificate of registration—as well as the implementation of certain extra-legal practices such as fencing and land development, constitute effective measures for securing land ownership for Congolese citizens.
