The Electronic Transactions Law (ETL), issued by Royal Decree No. M/8 and dated 26 March 2007, provides guidelines for the use of electronic transactions (defined broadly as "any exchange, communication, contracting or other procedure, performed or executed, wholly or partially, by electronic means") and electronic signatures (defined as "electronic data included in, attached to or logically associated with an electronic transaction used to verify the identify and approval of the person signing it and to detect any change to the transaction after signature"). The ETL in principle recognizes the legal effect of "electronic signatures" provided that certain conditions, requirements and specifications are met under the ETL and its Implementing Regulations (No. 1/1429 and issued on 18 March 2008). There are a number of documents and transactions to which the ETL does not apply (for example, transactions relating to personal status law, amongst others).
As there is no system of precedent and cases are not published as a matter of course, the extent to which a KSA court would enforce an electronic signature is uncertain, particularly if the veracity of such signature is challenged. Depending upon the circumstances, it may be prudent to have contracts/documents also physically signed on paper by the relevant parties.
