Legal Nature of the Contract:
The exchange of land for future construction, also known as a swap with a developer, is a legal concept increasingly used in the real estate sector, especially during times when access to credit is limited or when landowners seek to obtain a direct return without assuming the risks and complications of undertaking a development project themselves.
In essence, it is a contract in which the landowner transfers their property to a real estate developer, who in return commits to delivering a portion of what is built on that land: homes, commercial units, parking spaces, storage rooms, or any other registrable unit previously defined in the agreement. There is no immediate monetary payment, but rather an exchange of goods: present land for future construction.
This type of contract, although not explicitly regulated in the Civil Code, is entirely valid and has been upheld by case law as a form of barter under Article 1538 of the Civil Code.
In Catalonia, Law 3/2017, of February 15, of Book Six of the Civil Code of Catalonia, relating to obligations and contracts, and amending Books One through Five, provides specific regulation for this type of contract, understood as one in which the ownership of a property, urban development rights, or any real right granting the authority to build is transferred in exchange for a future construction or one resulting from rehabilitation.
Key Elements for Legal Certainty:
For this operation to be secure and beneficial for both parties, the contract must be carefully drafted. One of the key elements is the detailed description of the units to be delivered in the future: their characteristics, location, quality standards, delivery deadlines, and compensation mechanisms in case of default must be clearly defined. The greater the degree of individualization of the future units, the more legal certainty for the transferring landowner.
From the developer’s perspective, the main advantage of this model is access to land without a large initial outlay, allowing them to allocate financial resources to construction and marketing. For the landowner, the benefits are also significant: they can transform a non-liquid asset into a set of completed real estate units with potentially greater value, without becoming directly involved in development, permits, works, or financing.
Associated Risks:
However, this operation also entails risks, especially for the landowner. Developer insolvency, construction delays, planning breaches, or building defects are some of the scenarios that could endanger the agreement. For this reason, it is advisable to include guarantee clauses in the contract, such as suspensive conditions (e.g., the contract only becomes effective upon obtaining the building permit), bank guarantees, surety insurance, penalties for delays, and even the possibility of registering real rights in favor of the landowner over the future constructions.
The tax implications of a swap with a developer must also be carefully considered. If the landowner is a private individual, the transaction will be subject to the Transfer Tax and municipal capital gains tax. If, on the other hand, the transferor is a business or professional, the operation may be subject to VAT. Additionally, under personal income tax (IRPF), the transferor will be taxed on the capital gain, calculated as the difference between the value of the goods received and the acquisition value of the land.
