Property rights are rights that have been passed down from generation to generation, the strongest and most complete that people can have on land. Ownership of property rights can be granted to individuals and legal entities originating from the land of the Indonesian nation or state land. However, not all state land can be granted property rights, including marine and coastal areas. The ownership rights in the area cannot be granted because it is still state land and its full control is owned by the state so that it cannot be burdened by property rights. The research method used in writing this thesis is normative juridical research.

Based on the results of the study, it can be concluded that the legal status and ownership of certificates over coastal areas or equivalent beaches, are areas controlled by the State so that neither individuals nor legal entities are entitled to obtain property rights in the form of certificates for the area, therefore the suggestion is The National Land Agency as an agency that has the right to issue certificates of ownership should conduct research on objects that are used as property rights certificates, so that it does not become a problem in the future considering that coastal areas or coastal equivalents are areas controlled by the state which can be designated for the public interest for the welfare of the community.
