The Rise of E‑Contracts: Are Clicks as Binding as Signatures?

Introduction:

The digital revolution has transformed how contracts are made, enabling agreements to be executed online without a handwritten signature. Yet the core principles of contract law, including offer, acceptance, consideration, and intent, remain just as fundamental. Electronic contracts or e‑contracts arise when these elements are expressed through digital means. Common examples include clickwrap agreements, where a user must click “I agree” after viewing terms and browsewrap agreements, where terms are accessible by hyperlink but no explicit consent is given. Courts typically focus on whether users received fair notice of the terms and provided affirmative assent, particularly in clickwrap cases. This blog examines how legal systems treat e‑contracts and electronic signatures. It analyses key laws, compares case law across jurisdictions, and discusses challenges of design, consent, and blockchain. The discussion concludes with an analysis of Bangladesh’s legal framework and suggestions to strengthen the enforceability of e‑contracts nationally.

Doctrinal Foundations of Contract Law in the Digital Age:

Contract law’s core principles like offer, acceptance, consideration, and intention apply equally online. How assent and formality are obtained is the primary innovation in e-contracts. Electronic signatures, emails, click confirmations, and other forms of electronic communication have supplanted traditional signatures, which historically demonstrated assent and legitimacy. The doctrine of functional equivalence holds that an electronic record or signature is valid if it meets the same purposes as paper. According to the doctrine of functional equivalence, an electronic signature or record is legitimate if it serves the same functions as paper. For instance, non-discrimination is embodied in UNCITRAL's Model Law on Electronic Commerce (1996), which states that a document cannot be refused legal effect just because it is electronic. As technology has advanced, so too has the law. Unless there are legislative exclusions (such as wills or negotiable instruments), courts will typically enforce an e-contract regardless of its format if it demonstrates the parties' joint consent and intent. Nonetheless, courts require evidence of assent. Clickwrap (requiring an affirmative click) almost always provides enforceable assent because the user has both notice of terms (displayed on screen) and takes action.  By contrast, browsewrap (terms only accessible via link) is scrutinized. Without explicit action, assent depends on whether a “reasonably prudent” user would have notice of the terms.  Thus, enforceability hinges on notice and manifestation of assent, adapted to web design. In Specht v. Netscape Communications Corporation, held a download button insufficient to bind users to license terms hidden off‑screen. Modern cases likewise consider placement, conspicuousness, and required clicks to gauge consent.

Key Legal Instruments Across the World:

United States: In the United States, the Electronic Signatures in Global and National Commerce Act, 2000 known as ESIGN Act and the Uniform Electronic Transactions Act (UETA), 1999 constitute the core statutory regime for electronic transactions. are the cornerstone laws. The ESIGN Act provides that a transaction “in or affecting interstate or foreign commerce” may not be denied legal effect solely because it is conducted electronically. It defines an electronic signature broadly to include any electronic sound, symbol, or process that is attached to or logically associated with a contract or record and executed or adopted with the intent to sign. Similarly, the Uniform Electronic Transactions Act (UETA), adopted by most U.S. states, accords electronic records and signatures the same legal validity as their paper-based counterparts, subject to limited statutory exclusions. In practice, this means that utilising a digital certificate, clicking "I agree," or putting one's name in an email can all fulfil the legal criteria for writing and signing. Both laws support technology neutrality, supporting any secure form of signing as long as intent and integrity can be proven. However, they do mandate minimal consumer disclosures for specific electronic transactions.

European Union: The eIDAS Regulation (EU) 910/2014 governs electronic transactions within the European Union and establishes three categories of electronic signatures: simple, advanced, and qualified. Importantly, Article 25 which talks about legal effects of electronic signatures and stipulates that the mere fact that an electronic signature is electronic does not negate its legal force or validity. In other words, unless a more complex form is needed, even a simple click-signature is acceptable. A certified digital certificate and secure device serve as the foundation for a qualified electronic signature (QES), which is legally equivalent to a handwritten signature. Additionally, eIDAS requires that these signatures be trusted across national borders. Digital offers and acceptances are likewise regarded as legally binding for the formation of contracts under the EU's Electronic Commerce Directive (2000/31/EC). In El Majdoub v. CarsOnTheWeb.Deutschland GmbH the Court of Justice of the European Union (CJEU) confirmed that clickwrap techniques can meet formal writing requirements. The Court further held that providing users with the opportunity to print or save conditions is sufficient to make a clickwrap consent "in writing" for jurisdiction clauses.

Global Models: The United Nations Commission on International Trade Law (UNCITRAL) has led to international harmonisation through the Model Law on Electronic Commerce, 1996 which embed the principles of non-discrimination, functional equivalence and later echoed in UNCITRAL’s Model Law on Electronic Signatures, 2001making clear that no specific technology is required and that any reliable form of electronic signature can satisfy legal requirements. Although the Model Law does not expressly equate digital signatures with handwritten ones, its Explanatory Guide underscores the principle of equal treatment, stating that nothing in the Law should be applied so as to exclude any method of creating an electronic signature that satisfies the requirement of reliability. Thus, a technologically neutral framework exists: as long as the signature method is sufficiently secure for its purpose, the law will generally recognise it.

UNCITRAL and Smart Contracts: By analogy, new technology is also included by UNCITRAL's framework. Although self-executing code, or blockchain-based smart contracts, may not have a conventional "signature," they may nevertheless be enforceable if they satisfy contractual requirements, according to UNCITRAL principles such as non-discrimination, technological neutrality, and functional equivalence. Smart contracts are seen as electronic records, or data communications. It may satisfy offer and acceptance if the code's deployment is seen as an agreement to terms, such as when bitcoin is sent. According to UNCITRAL, a smart contract must be readable for future reference in order to be considered a "writing," and the technique such as key-based authentication must accurately identify the party in order for it to be considered "signed." Although smart contracts are not yet specifically governed by any national law, they are generally governed by current contract and e-signature regulations.

Bangladesh: The primary law governing e-commerce in Bangladesh is the Information and Communication Technology (ICT) Act, 2006. It interchangeably utilises "digital signature" and "electronic signature." The Act requires that an electronic signature must identify the signatory, be unique, and be attached to data to show any alteration. The integration of electronic records into the legal system is further enhanced by the Evidence (Amendment) Acts of 2010 and 2022. Amendments made in 2022 give presumptive evidence weight to a "secure digital signature" that satisfies stringent requirements for originality, control, and integrity. This implies that, similar to a verified handwriting signature, the law will assume that a party's usage of a secure digital signature certified by the government's Certifying Authority is that of the signatory. In practice, therefore, contracts electronically signed via approved digital certificates have legal force in Bangladesh. However, certain documents like wills, power of attorney, property sales, etc., still require ink signatures by law. There is no direct Bangladeshi case law specifically on clickwrap; ICT or Evidence Act compliance is usually assumed in commercial disputes.  

Design, Consent, and Emerging Technologies:

User Interface and Consent: Enforcement of e‑contracts depends critically on how consent is obtained. “Consent” in the digital realm is only as valid as the user’s understanding. Designers must ensure that terms are presented conspicuously and that users take deliberate action to assent. Dark patterns or obscure terms can invalidate consent. Legal authorities (e.g., European Union consumer protection agencies) now warn against misleading consent mechanisms. Bangladesh’s the National Information and Communication Technology Policy 2018 and the Organization for Economic Cooperation and Development (OECD) guidelines urge transparency in user interfaces. For example, pre-ticked boxes or hidden terms can render a contract unenforceable under principles of unconscionability or unfair practice. In Nguyen v. Barnes & Noble Inc. case, the U.S Court have held that a mere hyperlink to terms is insufficient notice absent an explicit prompt. Best practice is the “clickwrap” model: require users to scroll through or at least check a box next to the terms before agreeing, and make terms unmissable (large, bold, near the action button). Practically, such design clarity helps demonstrate “fair notice” should the issue ever reach litigation.

Smart Contracts and Blockchain: Blockchain-enabled smart contracts pose unique challenges. On one hand, they automate performance: terms such as “if condition X, then transfer payment” are coded on a distributed ledger. This reduces human error and accelerates transactions. However, several legal questions arise, such as whether each block of code constitutes a “contract” in itself, how offer and acceptance are manifested within the system, and whether the parties’ private keys can be treated as legally valid signatures. UNCITRAL’s recent work suggests existing e‑contract principles generally cover smart contracts. The key is identifying the parties and their intent. For example, deploying a smart contract and transferring cryptocurrency into it is analogous to signing and delivering a contract. The registry of transactions on a blockchain serves as a durable record. If private keys or cryptographic proofs can be linked to individuals, they fulfill signature requirements. Several jurisdictions such as Malaysia, the United Kingdom, and the United States have indicated that so long as traditional elements are met, even code‑based agreements can be enforced. However, practical challenges remain, including questions of governing jurisdiction, mechanisms for addressing errors in immutable code, and the availability of legal remedies. In response, some regulators have begun to explicitly recognise blockchain records as “data messages” within existing legal frameworks. Bangladesh has not yet addressed smart contracts specifically, but the principle of technological neutrality suggests smart contracts should not be categorically void. Nonetheless, legislative clarification may be needed to give certainty to complex blockchain transactions.

E‑Contract Challenges and Practical Issues:

Security and Authentication: The enforceability of e‑contracts depends on security. Parties must trust that signatures are genuine and records unaltered. Legal frameworks such as eIDAS, Information Technology Acts, and ICT laws typically require reliable authentication methods, including public key infrastructure (PKI) and secure digital certificates. In practice, Bangladesh used licensed Certifying Authorities operating under strict government regulation to issue digital certificates and support secure electronic transactions. Cross-border validity can be an issue as an e-signature valid in India may not automatically have legal weight in the EU though eIDAS does provide for mutual recognition among EU states. Bangladesh’s 2015 initiation of cross-border PKI recognition through bilateral agreement with countries like Sri Lanka is a step towards technical and legal interoperability. If parties from different jurisdictions enter into an online contract, they should explicitly agree on the applicable governing law and clarify whether other country’s e-signature technology is valid and acceptable.

Proof and Admissibility: Even when a contract is valid proving it validity in court required evidence of the electronic records. In most legal systems, including Bangladesh through the recent amendments to the Evidence Act, 187 and the U.S under the Federal Rules of Evidence recognise electronic records as evidence. However, the quality of evidence matters. In Bangladesh, a “secure digital signature” has a rebuttable presumption of authenticity while other forms of electronic signatures sent via email require forensic analysis or expert testimony about system logs and metadata. Courts in India have been willing to look at email headers and server logs as evidence of agreement. The U.S. courts generally allow admission of electronic records if their integrity is demonstrable such as using hashes, timestamps. On the other hand, consumer protection agencies sometimes scrutinise fine print or arbitration clauses in online contracts, if a party claims they never saw the terms. In that case, the burden falls on the drafter to show notice was adequate.

Consumer Protection: E-commerce often involves consumers, which requires additional rules for consumer protection. For example, in the EU, consumer contracts must include certain disclosures such as identity of seller, total price, etc. before clicking “I agree,” without seeing mandatory information could render a consumer contract void under consumer rights directive. Bangladesh’s recent amendments to the consumer protection law may be extended to e-commerce, imposing duties on online sellers. User interfaces must therefore not only get consent but also present required information like pricing, returns policy, etc., clearly. Forced clickwrap assent cannot override statutory consumer rights like right of withdrawal. Courts have struck down e-contract terms such as disclaimers or restricted remedies if they conflict with consumer statutes.

Conclusions and Recommendations:

Clicks can indeed be as binding as signatures when the law’s requirements of consent and reliability are met. Jurisdictions including the US, EU, India, Indonesia, and Bangladesh, increasingly recognise electronic contracts and signatures as legally equivalent to paper-based agreements. Courts generally uphold clickwrap agreements, while scrutinising browsewrap for lack of clear assent. The central challenge is ensuring that online consent is real and informed, which requires avoiding deceptive design practices and ensuring that “Agree” actions are unambiguous. As technology evolves, legal systems must adapt to cover smart contracts, blockchain records, and AI-driven transactions within the framework of e-signature and evidence laws.

For Bangladesh, specific reforms are needed to strengthen enforceability and confidence in digital transactions. Legislative clarity through amendments to the Contracts Act and ICT Act would eliminate doubts about e-contract validity, while judicial training and clear guidelines would help courts consistently admit electronic evidence. Public awareness campaigns can build trust in e-signatures, supported by infrastructure upgrades such as stronger PKI systems and secure digital identity. International harmonisation, through engagement with UNCITRAL conventions and regional protocols would improve cross-border enforceability, while consumer protection rules should prohibit misleading consent mechanisms and mandate plain-language summaries. Looking ahead, Bangladesh should also clarify the legal status of smart contracts and blockchain records. By aligning with global best practices and modernising its framework, Bangladesh can ensure that clicks provide the same legal certainty as handwritten signatures, reinforcing confidence in its digital economy.
