These are not simple formalities
Many everyday situations require changes to a plot or a building: from two siblings who inherit the same piece of land to someone putting up a block of flats on a building plot. Doing it safely usually requires a lawyer who knows civil, planning and tax law, plus technical experts: surveyors or agricultural engineers to divide or merge rural land, and architects or building engineers to declare buildings and divide them into flats. If any piece is missing, you risk spending time and money without ever registering anything.
Boundary demarcation: where your land ends
The Código Civil gives every owner the right to have their land demarcated (deslinde), that is, to fix its limits after summoning the neighbouring owners. If there is agreement, it can be formalised before a notary or a land registrar through non-contentious proceedings (jurisdicción voluntaria). If a neighbour objects, the matter goes to court. Before getting there, it is worth gathering deeds, cadastral maps, old photographs and a technical survey, because they are the basis of any agreement or claim.
Segregating or merging plots
Segregating (segregación) means separating part of a property to create a new one. For the notary to authorise the deed and the land registrar to register it, you need a municipal licence or a declaration that no licence is required, known as a declaración de innecesariedad. On rural land there are two limits to bear in mind:
- The minimum farming unit (unidad mínima de cultivo), set by the Junta de Andalucía according to the municipality and the type of land. Below it, as a rule, land cannot be divided for farming purposes.
- The ban on urban-style plot division (parcelación urbanística), that is, dividing the countryside into plots intended for building homes.
Merging (agrupación) is the opposite: combining several adjoining plots into a single registered property. It is usually simpler, but it requires the Land Registry and Cadastre descriptions to be properly aligned. If they are not, they will first need correcting through the Land Registry and Cadastre entries.
New buildings and horizontal division
When you build, the building does not appear in the Land Registry by itself. You need to sign a deed of declaration of new building (declaración de obra nueva), with the technical expert’s certificate and the licence or sworn statement (declaración responsable) that applies. For homes, ten-year structural insurance (seguro decenal) is also usually required, with exceptions such as a self-builder putting up a home for their own use. If the building is old and has no licence, in some cases it can be declared on the basis of its age; I explain this on the regularising properties page.
Horizontal division (división horizontal) is the next step when the building has several homes or commercial units. It is governed by the Ley de Propiedad Horizontal, Spain’s law on buildings divided into separately owned units. The document describes each flat or unit as an independent property, assigns it a share in the common elements and may include internal rules. If the division creates more homes or units than the licence allowed, a new municipal authorisation is needed.
My role is to study your case and give you clear answers on whether it is possible, the steps, the budget, the estimated time and the possible drawbacks. I can then handle all the formalities so they are carried out as we planned.
