Land and space are major driving factors in doing business in urban areas. Cities around the world are performing land management techniques to achieve sustainable urban development. The World Bank acknowledges the importance of land management practices and promotes it as the Ease Of Doing Business (EODB) indicators for a supportive environment for economic activities. In improving a city's competitiveness, local governments need to establish a reliable Land Administration System to organize unrenewable urban land and spaces and simultaneously reduce information asymmetry between actors. A modernized LAS is needed to accommodate the four functions of land management: land tenure, land value, land-use planning, and land development. The ISO 19152:2012 on Land Administration Domain Model (LADM) standard offers a foundation to establish information interoperability in land management that is crucial in modeling the relationship between people and land (and space), the geometrical components, as well as documented Rights, Responsibilities, and Restrictions (RRRs) in land. To promote the exchange of information between the domains of land administration domain and spatial planning, an extension of LADM, the Spatial Plan Information Package (SP Package), was proposed to support cities organizing information in land management. This article presents the proposed spatial plan information extension to the LADM country profile for Indonesia. This work also develops a proof-of-concept of the package in the two biggest Indonesian cities (Jakarta and Bandung) with adaptation to the current national data management policies. Our research shows positive results on making the LADM country profile reflect on the real condition and improving LAS's adaptability to be integrated with the Spatial Information Infrastructure.

Condominium is a special and relatively new type of property right emerged in the last century to be a remedy for the management problems in multi-unit buildings. There are many types of condominium regimes, as described in EUI (2005), UNECE (2005) and van der Merwe (2016). The common elements include: (a) Individual right to an apartment, (b) co-ownership (joint ownership) of the common property or the whole property, and (c) membership of an incorporated or unincorporated owners' association (van der Merwe, 2015, p. 5). The ownership shares in the common property are here referred to as co-ownership shares; yet, alternative terms include ownership fraction, condominium share, participation quota, share value, and unit entitlement. Generally, these shares will determine the proportional contribution to the common expenses and the share of common profits, as well as the voting power of each condominium unit owner in the administration of the condominium. The most common approaches to the determination of the co-ownership shares are based on equality, relative size or relative value of each condominium unit, or a combination of such (van der Merwe, 1994, p. 57–58). The literature presents detailed descriptions and comparative analysis related to condominium systems in different jurisdictions (e.g. van der Merwe, 2015; 2016; Paulsson, 2007; EUI, 2005; UNECE, 2005); however, the procedural aspects related to the allotment of co-ownership shares still need to be further investigated. This article aims to describe condominium systems in the Netherlands, Sweden and Turkey, and compare legal provisions and procedures related to the allotment of co-ownership shares in these jurisdictions. The main purpose is to clarify the methodologies behind the determination of the co-ownership shares in national systems to bring new insights to countries, which are trying to revise their national provisions.

Cities establish and maintain Land Administration Systems (LAS) to manage information about the land and urban space. Recognizing the importance of the urban space for sustainable development, information from spatial planning will affect land administration and vice versa. Therefore, every aspect that influences land use, both from spatial planning and land administration should be identified, documented, and standardized as they contain legally binding rules for governments and citizens. The Land Administration Domain Model (LADM), ISO standard 19152:2012, offers guidelines to ensure interoperability in the representation of Rights, Restrictions, and Responsibilities (RRRs). LADM is also capable of standardizing multi-dimensional representation, including the temporal capability for documenting and visualizing all legal aspects of land use or space. This paper discusses how to construct interoperable information between the spatial plan and land administration. We present the standardization of spatial planning information and land administration as subsets of land-related information. The paper proposes the development of a spatial planning package within the existing LADM standard.

Purpose: A paradigm in circular economy (CE) is that suppliers retain ownership of their products and materials, and that the users “only” pay for services. In many legal systems, however, elements incorporated in a building are considered to be fixtures, and therefore legally part of the building. This means that ensuring multi-cyclic behaviour of individual building elements (e.g. the facade or a window) is not so evident. This paper explores, from the perspective of Dutch law, how to secure the ownership of the supplier or to find alternatives within the existing system of property law. Design/methodology/approach: The authors performed a literature review of both CE and (Dutch) property law. The results of these reviews are discussed and illustrated by legal case studies. Findings: The options principally advocated within CE to retain ownership of building parts leave legal uncertainties and do not offer a solid basis for the development of circular business models, especially considering immovables and fixtures. For these categories, buy-back and take-back contracts, and models for reuse and recycling seem more promising. Research limitations/implications: The research is limited to a literature review. Although the legal principles discussed in this paper are valid for both civil and common law systems, and similar findings might, therefore, be expected internationally, this study focused on the specific Dutch legal context. Comparative legal research and research of best practices in the building industry is needed to test the applicability of the findings in an international context. Practical implications: Following the findings, CE initiatives within real estate and the construction industry should focus on alternative implementations of the operational lease concept, taking into account CE’s ambitions to reduce the extraction of raw materials. Originality/value: At the moment the challenges that property law poses CE, real estate and operational lease are hardly discussed within the literature. This paper explores this gap.
