The subdivision (partition) of a land plot represents a legal procedure by which one immovable property is divided into two or more separate land plots. It may be carried out either voluntarily, by mutual agreement between the co-owners, or through judicial proceedings where no agreement exists between them. Regardless of the form, any subdivision must be carried out in strict compliance with the requirements of the law. Consequently, when a land plot is subdivided, the newly created plots must comply with the legally prescribed minimum dimensions.

Bulgarian law recognizes two forms of partition: voluntary and judicial, with the possibility for the parties, in pending court proceedings, to conclude an agreement known as a judicial settlement, which must be approved by the court hearing the case. Judicial partition begins with the filing of a claim before the district court and proceeds in two phases. In the first phase, the right to partition and the ownership shares of the parties are established, while in the second phase the actual subdivision of the property is carried out. Within the proceedings, the court may require the parties to prepare an investment project for amendment of the detailed development plan.

Voluntary partition is carried out by means of a written agreement, which is notarised and registered in the Property Register. However, the mere consent of the co-owners is not sufficient – the new plots must first be created and their cadastral identifiers must be issued.

For the subdivision of a land plot to be permissible, the newly formed plots must meet the minimum requirements for frontage and area established by law. The creation of plots below the statutory minimum parameters is not allowed, nor is the formation of plots resulting in an unlawful layout of existing or authorised buildings.

When subdividing a regulated land plot in order to form new plots, the division must be approved by the municipal administration. Pursuant to Article 201 of the Spatial Development Act (SDA), a favourable opinion may be issued only if two conditions are met: the subdivision must not result in an unlawful placement of existing or authorised buildings, and no new land plots may be created with frontage or area below the minimum limits established under Article 19 of the SDA.

Where the subject of the partition is an unregulated land plot, the procedure is also subject to statutory restrictions. With regard to agricultural land, Article 72 of the Inheritance Act provides that arable land may not be divided into parts smaller than 3 decares, meadows into parts smaller than 2 decares, and vineyards and orchards into parts smaller than 1 decare. With regard to forest land, § 3 of the Transitional and Final Provisions of the Forest and Forest Land Restitution Act stipulates that real shares resulting from the disposal or partition of restored co-owned forest land may not be smaller than one decare.

The subdivision of a land plot is a complex legal and technical procedure requiring coordination between the co-owners, the municipal administration, the court, the cadastral authority and the notary. Compliance with statutory requirements is essential, as any violation may lead to the invalidity of the partition. Therefore, when planning such a procedure, it is advisable to seek professional legal and geodetic assistance.
