Legality of eSignatures in Angola
Background
Electronic signatures are rapidly transforming the document authentication landscape in Angola and globally by introducing efficient and environmentally conscious methods that are building momentum. The shift from paper to digital signatures accelerates the completion of various dealings.
It is crucial to select an electronic signature tool that aligns with the nation’s legal stipulations, specifically the regulation on information society technologies and services, for successful adoption in Angola1. This is to ascertain the legal validity of electronic signatures compared with the holographic ones in Angola. Despite the progressive acceptance, it’s essential to recognize that some documents may still need a physical signature, and seeking legal consultation is advisable to navigate variable regional laws2.
The importance of security surrounding electronic signature platforms cannot be understated. Services must integrate robust protection features such as data encryption, verification of signer identities, and provision of audit trails to deter unauthorized access and guarantee document authenticity. For instance, BoldSign offers these imperative security features and complies with legal and security protocols.
Angolan enterprises must emphasize legal conformity, elevate security measures, and choose user-friendly platforms for integrating electronic signatures into their business frameworks. This approach boosts productivity and ensures the protection of their business exchanges.
Overview of the eSignature regulations
Presidential Decree No. 312/18 of December 21, 2018, establishes the legal framework for the implementation of the Standard Audit File for Tax Purposes (SAF-T AO) in Angola. The decree mandates the utilization of a standard electronic format for accounting and tax data, with the aim of increasing transparency, facilitating tax audits, and encouraging compliance with tax requirements3.
Executive Decree No. 74/19 of 6 March 2019, enacted in Angola, sets out the regulations and conditions for the application of validation of electronic invoicing systems of taxpayers and the use of digital signatures4,
The regulation on information society technologies and services regulates the operation of electronic signatures5. The Act gives eSignature the legal validity equal to that granted to the wet-ink signature prior to its enactment.
The Angolan regulation grants all individuals the freedom to execute their contracts electronically upon agreement by the contracting parties6. Such contracts, however, shall not be denied legal validity merely because they were completed electronically.
The regulation categorizes the electronic signatures into7:
- Standard electronic signatures
- Advanced electronic signatures
- Qualified electronic signatures
A standard electronic signature is any data, including a sound, symbol, or process, executed or adopted to identify a person and indicate that person’s approval or intention regarding the information contained in a data message and which is attached to or logically associated with that data message.
An advanced electronic signature is designed so that, together with a security procedure, it can be verified that the signature is:
- Uniquely linked to the signer
- Capable of identifying the signatories
- Created using means that the signer can keep their sole control
- Linked to the data it relates to, so that any subsequent change to the data is detectable
Uniquely linked to a person
A secure electronic signature must be uniquely connected to the person who is using it. The signature must be uniquely created with methods that only the signer has access to, like a private key and confidential information, to verify their identity.
Use and incorporation of their sole control
The person using the secure electronic signature must have sole control over the means of creating the signature. Typically, this requires managing a key pair or two-factor authentication, with the signer exclusively holding the private key to prevent unauthorized signature forgery.
Identify the person using the technological process
The process used to create the signature must be capable of identifying the person signing. This may include using a biometric signature, a personal identification number (PIN), an email address, or even a company registration number.
Track down alterations made after signing
It is essential to preserve the authenticity of the signed document. Modifications made to the document post-signature should be identifiable. This is commonly accomplished through an audit trail. Audit trails record the signer’s IP address, timestamps of key signing events, and location, providing proof of identity, timing, and place of signature.
A qualified electronic signature is an advanced electronic signature that meets the following requirements8:
- It is based on an asymmetric cryptographic system composed of an algorithm or series of algorithms, by means of which a pair of unique and interdependent asymmetric keys is generated, one of which is private (signature creation data) and the other public (signature verification data), or satisfies the exact security requirements as asymmetric keys;
- It is based on a qualified certificate, and
- It is created using a secure signature creation device.

How does BoldSign help
The following elements of compliance available within BoldSign can be used to comply with Angolan eSignature laws:
- Secure and unique signing link: A secure and unique link to sign a document is sent directly to the signer’s email address. This ensures that the document is only accessed by the intended signer and cannot be tampered with.
- Password protection: Senders can specify a password that needs to be entered before viewing and signing a document. This adds another layer of security to the signing process.
- Audit trail: The IP address of the signer and timestamps for all significant events in the signing process are recorded in an audit trail. This provides a record of who signed the document, when, and where.
- Digital signature: The final document is digitally signed with an AATL-compliant certificate. This ensures that the document cannot be tampered with without invalidating the signature.
- Consent: Signers are asked to confirm their intent to sign electronically and informed that they could opt out. This ensures that the signer is aware of the implications of signing electronically and has given their consent.
- Custom terms: Get your signers to agree to a custom set of terms. This can be useful to ensure additional security or that the signer understands the terms of the document.
