E-signatures in commercial contracts in Spain

Regarding private agreements subject to our civil and our commercial code, legal requirements for a valid agreement are (i) the parties' consent; (ii) the subject of the agreement; (iii) the purpose of the agreement; and (iv) under very specific circumstances, when there is a legal provision that establishes it, agreements will need to be in written form to be valid and enforceable.

As for agreements entered into with consumers, the regulation is much stricter and lays down greater information requirements, including the following:

  1. Name, corporate name and registered offices of the entrepreneur responsible for the commercial offer and, if applicable, name, corporate name of the registered offices of the entrepreneur on behalf of which they act.
  2. The essential characteristics of the product or service in a way which is adequate according to the nature and means of communication used.
  3. The complete final price, including taxes, and break down, if applicable, of the amount of the increases or discounts which apply to the offer and additional costs passed on to the consumer.
  4. Payment procedures, delivery times and contract execution, as well as the system for processing claims, when they do not fully comply with the professional diligence as defined in the Spanish Unfair Competition Act.
  5. If applicable, the existence of the right to withdraw from the contract.It should be noted that information requirements are even stricter with regard to distance contracts entered into with consumers.

In these cases, in addition to the information listed above, the following information shall be provided:

  1. The complete address of the entrepreneur's establishment and the telephone number, fax number and email, when applicable, with the purpose of allowing the consumer to contact and communicate with them swiftly and efficiently, as well as, when applicable, the complete address and identity of the entrepreneur on which behalf they act.
  2. The cost for using the distance communication technique to conclude the contract, if such cost is calculated on a different basis than a basic tariff.
  3. The language or languages in which the contract may be concluded, when it is not the language in which the information was offered previously to concluding the contract.
  4. When a withdrawal right procedure exists, the conditions, deadline and procedures to exercise this right, as well as the withdrawal form.
  5. When applicable, the indication that the consumer shall have to bear with the cost of returning the products in case of withdrawal and, when the products, due to their nature, may not be returned normally by courier, the cost of their return.
  6. When, according to the regulations, the right of withdrawal does not apply, the indication that the consumer is not entitled to this right, or the circumstances under which the consumer shall lose this right when entitled to it.
  7. A reminder of the existence of a legal warranty of the conformity of the products.
  8. When applicable, the existence of after-sales assistance to the consumer, after-sales services and commercial warranties, as well as their conditions.
  9. The existence of relevant codes of conducts and the procedure to obtain copies of the same, if applicable.
  10. The duration of the contract, when applicable, or the conditions for the termination of the contract if its duration is indefinite or subject to automatic extensions.
  11. When applicable, the minimum duration of the consumer's obligations derived from the contract.
  12. When applicable, the existence and conditions of the deposit or other financial warranties which the consumer shall pay or provide at the entrepreneur's request.
  13. When applicable, the functionality of the digital contents, including the applicable security technical measures.
  14. When applicable, all relevant interoperability of the digital content with the apparatus and programs known by the entrepreneur or that the entrepreneur is reasonably expected to know.
  15. When applicable, the existence of an extrajudicial mechanism for claims and compensations to which the entrepreneur is subject and the methods to have access to them.

Regarding private agreements, written form is not required except for those cases provided for in the specific regulations.

As for agreements entered into with consumers, written form is required.

In those cases where the entrepreneur contracts the consumer by telephone in order to conclude a distance contract, they shall provide the consumer with a confirmation in writing or, except when the consumer opposes it, in any medium of a durable nature. The consumer shall only be bound once they have accepted the offer by their signature or by sending their agreement in writing which, among other mediums, may be done in paper, email, fax or sms.

Although the general rule is the freedom of form, there are certain cases in which written form is required, such as the following:

  • Consumer credit agreements;
  • Consumer agreements in general;
  • Employment agreements;
  • Certain Banking agreements;
  • Surface agreements and Lease agreements subject the Lease Spanish Act (Buildings)

According to the civil code when the following require written form it also requires to be granted before public notary:

  • agreements related to creation, transmission, modification or cancellation of rights in rem over real estate assets;
  • lease agreements of more than 6 years duration;
  • general power of attorneys;
  • assignment of rights and actions arising from an act established in a public deed.

There are no specific provisions regarding digital archiving and storage of electronic documents in Spain. There are, however, some regulations which should be observed when archiving documentation of any sort.

In this regard, according to the data protection regulations, appropriate technical and organisational measures should be implemented in order to ensure the protection of the personal information contained therein. Failure to do so shall result in very severe penalties in severe cases.

Moreover, there are other regulations, such as tax and money laundering related, which provide for minimum archiving terms regarding certain documentation (i.e., money laundering regulations lay down a term fo 10 years for certain documents).

Cybersecurity regulations also impose certain requirements regarding the security of the information upon companies which carry out certain essential services.

4. Main and relevant court practices

According to the Spanish case-law on this matter, the simple, advanced and qualified e-signatures have the same legal validity. 

Thus, there is no need to rely on a qualified e-signature to ensure the validity of an electronically signed legal statement if the e-signature consists of 1) data in electronic form linked to or logically linked with other electronic data; 2) is used as a means of authentication. According to the courts, in short, an e- signature will be any data that can be associated with a contract/legal statement.

However, if a legal statement (for which written form is required) is intended to be used as evidence in a legal proceeding and it is signed with a qualified e-signature it will be presumed to be valid. However, if it is signed with an advanced or simple e-signature, its validity must be proven by the parties concerned. This is known as "iuris tantum" evidence, which allows all the concerned parties to prove (or not) the validity of the electronic signature. 

5. In which cases are documents only with wet ink signatures accepted?

In accordance with the Spanish regulations, qualified electronic signatures have the same validity as handwritten wet ink signatures, in all forms of contractual relationship. Consequently, there cannot be any cases in which only wet ink is accepted.

Yes, according to art. 3.4. of the Spanish Electronic Signature Act 59/2003 ("ESA").

4. Electronic document signed with advanced electronic signature (AdES as defined in the eIDAS Regulation) without a time stamp

Yes, according to art. 3.4. of the Spanish Electronic Signature Act 59/2003 ("ESA").

5. Electronic document signed with advanced biometric signature

Yes. The ESA does not differentiate between adavanced biometric signatures and AdEs. The use of advanced biometic signatures does not jeopardize the legality and binding character of the content of the e-document.

However parties to that document may challenge that the signature was provided by the actual signee, in an more simplistic way than advanced biometric, AdES or QES. Moreover, depending on the circumtansces, this may be a criminal offence and would lead to a finding that the document does not bind the parties.
