Data Ownership and Data Trade in Privatized and/or Blockchain Based Land Registries

Any land registration system is a source of an enormous amount of data, created by several data producers, which only gradually is being discovered, valued and realised by those involved: Citizens whose property is on the register, governments which add geospatial data, commercial users who offer supplementary services, notaries and conveyancers adding legal information about, e.g., transfer and mortgages, judicial enforcement officers adding legal information about, e.g., seizures and attachment, and, last but not least, land registries themselves which are using the data that are stored under their supervision to create derived and (in a technical sense) manipulated data so they can provide any required information to users with information tools which they market as part of their business model. Added to this mix of (private and government) data producers and users now come IT companies, introducing blockchain technology. Thus making the question even more pressing: Who owns which data?

What Should We Do (or Not Do) with Land Administration Data?

Jan Moerkerke

ELRA - European Land Registry Association, Belgium

Traditional systems of land registration are under pressure lately. States consider them as being too expensive and also they meet difficulties in providing security of tenure over the bundle of rights custimary land rights may contain.

Furthermore for the organisation of the service the rapidly changing technological context has to be taken into account.

Privatisation of existing public services may be considered as a sollution.

In this contribution we try to review the pro's and contra's of this choice from a stakeholders point of view.

Nobody will deny that the land is spearheading economic growth.

Its administrative organization must therefore have transparent, secure and guaranteed management.

It is obvious that the use of the blockchain will confer these qualities on cadastral administrative data.

However, we must not neglect the questions and problems that may arise and that relate to both the system of registration of data and its consequences.

Initially, the implementation of cadastral data on the block chain raises the problem of the legal regime applicable to liability and of the degree of legal certainty provided to citizens.

In a second time it is on the contracts attached to the life of these data and their execution that the questions will concern: which law to apply? What about the forced execution of these contracts in case of non-execution?

Answering a question with another question can help you think further ...

Data Ownership and Data Trade in Privatized and/or Blockchain Based land Registries

Notar Leif Boettcher

Notar Dr. Leif Böttcher, LL.M.

Due to the outstanding importance of land as an economic good, all land registers have traditionally been kept by State authorities. Now that some States have privatised their land registers, the question of the legal fate of the data and access to them is becoming increasingly important: while some people fear that privatisation could lead to restrictions on access for consultation and that it could not be done free of charge, other emphasise the economic benefits of privatisation. However, these issues must be separated: The question of who keeps the land register does not reveal anything about who can access use or exploit the data and whether this access is to be granted free of charge. Various interests – those of the owners, the economic operators and the public – need to be reconciled. The function of the land register within the land transfer system also plays a decisive role.
