eSignature Tanzania: the short answer

Searched as eSignature Tanzania, electronic signature Tanzania, or "is an e-signature legal in Tanzania", the answer is the same: yes, for ordinary business documents, under Electronic Transactions Act, No. 13 of 2015. What varies is which documents are carved out and which tier of signature they need, and that is the part worth reading rather than the general rule.

Tanzania legislated in 2015 and drew a two-tier distinction that catches people out. Under the Electronic Transactions Act, an electronic signature is broadly recognised and electronic records are admissible in evidence. But where a written law requires a signature, section 63 calls for an advanced electronic signature, meaning one uniquely linked to the signer, capable of identifying them, created using means under their sole control, and linked to the data such that any subsequent change is detectable. For ordinary contracts between private parties, where no statute imposes a signature requirement, a simple electronic signature with a reliable record is workable and is what most businesses use. The Act also gives electronic evidence a clear route into court, which was the practical gap before 2015. Land transactions, wills and negotiable instruments sit outside the regime, as they do across the region.

FAQ

Is an electronic signature legally binding in Tanzania?

Yes for ordinary contracts under the Electronic Transactions Act 2015, and electronic records are admissible in evidence. Where a written law specifically requires a signature, the Act calls for an advanced electronic signature, which is a higher bar than a drawn mark, so identify whether a statute governs your document.

What counts as an advanced electronic signature in Tanzania?

One that is uniquely linked to the signer, can identify them, is created by means under their sole control, and is linked to the document so that any later change is detectable. Those are the four limbs, and a signature with a cryptographic seal and an audit trail is aimed squarely at them.

Are electronically signed documents accepted by Tanzanian courts?

The Act provides for the admissibility of electronic records and signatures, with the weight depending on the reliability of how they were generated, stored and communicated. A complete audit trail is what carries that weight.

What PDF Verified is, and what it is not

PDF Verified is a tool for preparing, signing, stamping and checking documents. It is not a law firm, a compliance service or a forensic examiner, and nothing here is legal, financial or compliance advice. Requirements differ by country, by document type and by the party asking, so check what applies to your document before you rely on it, and take advice where the document matters. You are responsible for the documents you create, sign and send, and for having the authority to do so: signing or stamping in somebody else name, or as an organisation you do not represent, is forgery whatever tool is used. To the extent the law allows, we accept no liability for how a document made with this tool is used or relied on. The full position is in our terms of service.
