How to subject an international contract to Spanish law?
What is an international contract?
An international contract is an agreement between parties from different countries that establishes binding rights and obligations.
This type of contract has unique characteristics, as it is influenced by the regulations of the countries involved.
If applicable law is not clearly established, conflicts or legal uncertainty may arise.
That is why subjecting an international contract to a specific legislation , such as Spanish law, provides greater legal certainty.
This allows the parties to have clarity regarding the rules that regulate the contract and the judicial system that will resolve possible conflicts.
Below, we explain the steps and key aspects to ensure your contract is governed by Spanish law.
How to subject an international contract to Spanish law
The Rome I Regulation , applicable in the European Union, allows the parties to a contract to choose the law that governs their relationship.
This principle of contractual autonomy is the basis for subjecting an international contract to Spanish law.
To do this, an applicable law clause must be included , which can take the following forms:
- Express clause: This is the most recommended form, as it explicitly establishes the legislation that will govern the contract. An example would be: "This contract will be governed by Spanish law.".
- Tacit clause:Although less common, in some cases the applicable law can be inferred from the content of the contract, such as the residence of the parties, the language used, the place of performance or the goods subject to the contract.
Furthermore, to ensure that any dispute is resolved by the courts of Spain, a jurisdictional submission clause must be included , stating that the parties agree to submit to the Spanish courts and tribunals.
For example: “The parties agree that any dispute arising from this contract will be resolved by the courts of [city in Spain]”.
What happens if a governing law clause is not included?
If you do not specify the applicable law or courts, the Rome I Regulation provides that the contract will be subject to the law of the country that has the closest connection with the agreement.
For example:
- Contracts for the sale of goods: The law of the country where the seller resides will apply.
- Provision of services: The law of the country where the service provider resides.
- Leasing of real estate: The law of the country where the property is located.
- Franchises: The law of the country where the franchisee resides.
- Distribution: The law of the country where the distributor resides.
- Transport contracts:
- Goods: Law of the country of residence of the carrier if delivery occurs there.
- Passengers: Law of the country where the passenger resides if the destination is in that country.
- Consumer contracts: The law of the consumer's country of residence, provided that the professional carries out commercial activities in that country.
- Insurance: The law of the country where the insurer is domiciled.
- Employment contracts: The law of the country where the worker provides his services.
Essential clauses in an international contract
In addition to the legislation and jurisdiction clauses, there are other provisions that must be considered to ensure a sound and clear international contract.
Among the most important are:
- Legal capacity of the parties: Confirm that all parties have the legal authority to sign the contract under their local law.
- Territory of application: Define the territorial scope of the rights and obligations of the contract.
- Confidentiality: Include provisions to protect sensitive information shared between the parties.
- Duration and renewal: Clearly establish the period of validity of the contract and the conditions for its renewal.
- Consequences of non-compliance: Detail what happens if one of the parties fails to comply with its obligations, including possible compensation or termination of the contract.
- Conflict resolution methods: Include alternative mechanisms such as mediation or arbitration, before resorting to the courts.
