Partition is a way to terminate co-ownership and any co-owner may seek it, even if there is an agreement to the contrary, unless the law provides otherwise or this is incompatible with the nature and purpose of the thing. The claim for partition is not time-barred. This general rule also applies when the common property is a yard in which a main building and extensions have been constructed. The legal basis is Article 34 of the Ownership Act, which expressly regulates both the right to request partition and the inapplicability of limitation to this claim.
The first question in such cases is whether the property can be divided “in kind.” The court allows a real (in-kind) partition only if each newly formed share can exist as an independent regulated land plot in accordance with the requirements of the Spatial Development Act. That Act introduces minimum size requirements for frontage and area when regulating plots for low-rise residential development and a restriction that physically defined parts may be acquired by transaction or by prescription only if they meet those sizes. For towns the minimum requirements are usually at least 14 metres frontage and 300 sq. m area, while for other categories of territories the law sets higher thresholds. If these parameters are not met, a partition in kind is not allowed and the procedure shifts to partition through public sale. The relevant provisions are Articles 19 and 200 of the Spatial Development Act.
Where forming the shares requires the subdivision of an existing regulated land plot, a change to street or courtyard regulation, or another planning action, the procedure under the detailed development plan applies, which is approved under the Spatial Development Act by the competent municipal authority. The partition court cannot “replace” urban planning; the case-law of the Supreme Court of Cassation has emphasized that when subdivision of a regulated plot or of a developed property is necessary, a real partition must comply with the effective or amended detailed plan, and in the absence of planning prerequisites a partition in kind is not allowed.
The mere existence of extensions does not in itself prevent partition, but it affects the manner of allocation. Under Article 92 of the Ownership Act the owner of the land is also the owner of the buildings erected on it, unless otherwise established. Such “otherwise” exists where a separate right to build (superficies) has been created or recognized for a particular building or extension in favour of a specific co-owner or a third party. In that event the structure is a separate object of ownership that does not “follow” the land by accession. For partition this means that an extension for which there is a separate right to build is taken into account as a separate object, and not as an appurtenance of the entire plot; if no such right exists, the extension is treated as part of the property and follows the ownership of the land.
When the extensions belong to different co-owners, a real partition must ensure for each share an independent and lawful access, compliance with setback distances and building rules under the Spatial Development Act. If this can be achieved through an amendment to the detailed development plan, the partition is carried out in accordance with the approved plan and the statutory minimum sizes; if it cannot be achieved, a partition in kind is not permitted and the property is realized through sale with distribution of the proceeds. In all cases the court verifies whether the formed shares meet the requirements of Article 19 of the Spatial Development Act and, where necessary, the planning procedure is followed before the final partition schedule is issued.
In summary, partition of a yard with extensions is admissible under the general conditions of Article 34 of the Ownership Act, but an actual division in kind is possible only if each share can exist as an independent regulated plot under the Spatial Development Act. Extensions follow the land unless there is a separate right to build; in that case they are treated as separate objects. Where planning requirements do not allow the formation of independent shares, partition is carried out by sale and distribution of the price among the co-owners.
