This article identifies the 12 most common mistakes made when buying land. The author examines the risks associated with purchasing agricultural land, gardens outside the built-up area of a municipality, forests and protected areas (Natura 2000), where nature conservation takes precedence. She also draws attention to hidden technical and administrative obstacles, such as exhausted utility-network capacity, access roads unacceptable to the building authority, heritage protection of old buildings, and historical defects arising from a previous settlement of co-ownership. The aim of the text is to educate clients not to give in to emotions and to invest in a preventive legal audit of the property before signing a contract.

Most clients on the property market have a clear vision of how they will use a plot of land. It happens, however, that insufficient verification of the legal status of the land before purchase leads to disappointment. Instead of the planned construction of a holiday cottage, the owner is left with nothing but an expensive garden with no possibility of building on it. Resist the marketing tactics of estate agencies and do not let yourself be pushed into signing a purchase contract without a clear assessment of all the legal factors relevant to using the land in the way you plan to buy it for.
The most common mistakes made by buyers include:
On the property market we frequently encounter offers of "bargain-priced" plots presented as building land, even though they are still recorded in the Land Registry (kataster) as arable land. In such cases, the low market price is often a direct reflection of the absence of compliance with the municipal zoning plan. Without that compliance, the plot remains, from a legal point of view, agricultural land on which individual construction is not possible. Withdrawal of the plot from the agricultural land fund is possible only once the plot is designated as an area intended for construction in the municipality's valid zoning documentation.
Gardens situated outside the built-up area of a municipality may seem an attractive option for recreational purposes or the construction of a cottage. It must be stressed, however, that their building potential is usually zero. The process of changing the land type to building land is in many cases administratively impassable, which can turn such an investment into legally unusable property.
Many plots lie within areas of European or national importance. Clients often assume that if the zoning plan permits construction, the matter is closed. In reality, the binding opinion of the nature conservation authority takes precedence. Even a parcel designated as buildable in the zoning plan may remain unbuildable if the planned construction would disturb habitats or the occurrence of protected species.
Acquiring forest land with the intention of building recreational structures carries a high legal and investment risk. The strict protection of the forest fund under special legislation severely limits any construction activity on such land, or prohibits it outright. Ownership of forest land does not in itself confer any automatic right to develop it according to the owner's individual wishes.
Permanent grassland outside the built-up area is often mistakenly regarded as "less protected" than arable land. In reality, under the Act on the Protection of Agricultural Land it forms an equal part of the agricultural land fund and is subject to the same strict restrictions. Any attempt to reclassify it as building land is assessed just as strictly as with arable land, with the administrative authorities considering in particular the soil quality rating and compliance with the zoning plan. If the municipality does not support development of the locality in question, the plot remains unbuildable in the long term, with no realistic prospect of a change in its use.
Clients often assume that if they can see an electricity pole or a utility shaft at the boundary of the plot, they automatically have a right to connect. In practice, however, the capacity of the networks in question may be exhausted, or the network operator may refuse to issue an approving opinion for a new customer. The existence of infrastructure nearby does not mean the existence of a legal entitlement to connection.
Clients often buy land convinced that access is "sorted", because along with the plot they also acquire a co-ownership share in the parcel under the access road. In practice, this is a very common illusion. A co-ownership share alone does not guarantee that the road is physically passable, technically adequate, or legally acceptable as access to a building.
When assessing a building project, the building authority strictly requires the access road to meet technical standards and fire-safety requirements (e.g. a minimum width and load-bearing capacity for fire-brigade vehicles) and to be connected without interruption to the public road network. If this private road does not meet the necessary technical parameters, or if you do not have a fully secured and uninterrupted right of passage and transit across the adjoining parcels all the way to the public road, the authority will not recognise it as lawful access — and the project may come to a complete halt as a result.
A further risk is the co-ownership of the road itself. If the road is co-owned in shares with dozens of strangers and there are no clear contractual rules on its use and financing, disputes arise over maintenance, repairs, drainage or lighting.
A client buys an old building intending to demolish it and build a new one on the same spot. If the building is listed as a national cultural monument, or is located in a heritage protection zone, demolition may be prohibited altogether, or made conditional on an exceptionally costly and lengthy process with the Monuments Board of the Slovak Republic (Pamiatkový úrad SR).
In property listings you will often come across labels such as "suitable for building a house" or "building plot". These claims must be treated purely as marketing communication, not as a legal guarantee. Clients often labour under the false impression that the estate agency bears legal responsibility for the condition of the land. The reality is different: responsibility for verifying the legal status of the property rests entirely with the buyer. The estate agency brokers the sale but is not a guarantor of the land's usability under the zoning plan. If it turns out after the purchase that building on the land is not possible, your contract with the estate agency usually gives you no legal basis for compensation for the resulting loss or for a refund of the commission. A listing is not zoning information – so never accept an agent's claims without supporting them with a relevant document (e.g. up-to-date zoning information or a binding opinion on the investment project).
By buying land that was in the past the subject of a settlement of fractional co-ownership, you may unwittingly take on the legal defects of that process as well. A frequent problem is a breach of the statutory pre-emption right of the other co-owners in previous transfers, where offers to purchase the shares were not properly delivered or were made in breach of the law. Such a failing can result in the relative invalidity of the legal acts, which the affected persons may assert in court within the 3-year limitation period. If the settlement process was not carried out in accordance with the law, the ownership title you have acquired may be challenged in the future. A legal review of the history of the acquisition of ownership is therefore an essential step to eliminate the risk of buying a property whose ownership can be called into question.
The argument that the neighbour got a permit does not mean you will get one too. The zoning plan may have changed in the meantime, or the neighbour's building may have been permitted under a different regime (e.g. years ago, when the regulations were more lenient). Every building project is assessed individually under the legislation and regulations in force at the time the application is filed.
Clients often think that if they buy two adjoining parcels, they can join them into one at will. Processes such as land consolidation or survey plans for merging parcels have their own strict rules, and if the plots are burdened with various encumbrances or liens, or are subject to different legal regimes, merging them can be legally very complicated.
Buying land is often the biggest investment of a lifetime. Do not be tempted by the prospect of a "bargain" purchase without a proper legal and technical audit. If you are planning to invest in property, we will be glad to help you with a comprehensive review of its legal status, an analysis of the zoning documentation, and the preparation of contractual documentation that will protect your interests. Prevention is always cheaper than resolving court disputes after the purchase.
