Witnesses, while not a party to the document being signed, remain one of the most important figures in confirming the legitimacy of a legally binding document in 2025. Their presence helps safeguard against future disputes and reinforces that all parties are entering the agreement freely and knowingly.
A witness is there to verify that the identities of the signing parties have been properly confirmed and that the document is being executed correctly. This extra layer of verification is especially important to ensure that no illegal action, such as duress or coercion, undermines the validity of the contract.
As a result, witnesses play a crucial role during the signing process. However, the eligibility and qualifications of a witness can vary depending on the type of document and the jurisdiction. It’s always best to check the specific requirements applicable to your situation.
Being aware of these differences can help you prepare for the witnessing process the next time you’re faced with a legal document. In this article, we’ve updated our guidance to reflect the current legal landscape in 2025, so you can feel confident that you’re following the best practices available today.
When Do Documents Need A Signature?
A document typically requires a signature when the law designates it as necessary for the document to be legally binding. In 2025, many official applications, deeds, wills, mortgage documents, guarantees, and contracts still call for a witness’s signature. Even with evolving digital processes, a traditional handwritten signature remains a cornerstone of legal validation.
Although a witness may not be a statutory requirement for every document, you can choose to include one as an additional safeguard. For more insight into effective contract formalities, check out our guidance on what makes a contract legally binding.
Who Can Be A Witness To A Signature?
The answer to who can act as a witness depends largely on the document. For many basic agreements, an ordinary witness will do—as long as they are over the age of 18, have the capacity to understand the act of witnessing, and can verify the signer’s identity. No specialised qualifications are required for routine documents.
On the other hand, some documents like affidavits, wills, or deeds may need to be witnessed by a person with specific legal authorisation—often a justice of the peace, a practising solicitor, or a notary public. This ensures compliance with stringent legal standards.
For a deeper understanding of who should witness your documents, you might also explore our Company Constitution guide, which outlines internal signing protocols for corporate documents.
Can A Family Member Witness A Signature?
Family members can often serve as witnesses and are sometimes even required—for example, a family member may be needed to witness an affidavit. The key consideration is that the family member must not be a beneficiary of the document. This helps maintain the impartiality of the witnessing process.
Provided the family member meets the general requirements of age and mental capacity, they can be a valid witness. Just ensure there is no conflict of interest that might later call the document’s integrity into question.
Can A Spouse Witness A Signature?
Yes, a spouse can witness a signature. The crucial point is that the spouse must not be a party to the contract or derive any direct benefit from the legal document being signed. This separation helps maintain the document’s impartiality.
Can A Bank Witness A Signature?
For financial documents such as mortgages or property transfers, witnesses are typically required. However, it’s highly unlikely that a banking institution will act as a witness since a witness is generally an individual, not an organisation. That said, many of these legal documents will still need a valid, independent witness signature.
Can A Director Witness Another Director’s Signature?
When it comes to signing company documents, the process can be a bit different. If a company seal is being used, the rules may require the signatures of two directors or a director in combination with a company secretary. In other situations, it is advisable to have an independent witness to avoid any potential conflicts of interest or challenges to the document’s validity.
The rules governing director actions are generally outlined in the Corporations Act 2001, and further details can often be found in your Company Constitution.
What Is A Statutory Declaration?
A statutory declaration is a formal, written statement of fact that is declared to be true in the presence of an authorised witness. This document is commonly used to clarify matters of truth, and its straightforward format outlines the facts and intentions relevant to the matter at hand.
You can download the recommended format for a Commonwealth statutory declaration here, which remains a trusted resource in 2025.
Who Can Witness A Statutory Declaration?
A statutory declaration must be witnessed by an authorised person. In NSW, for example, authorised individuals include:
- A justice of the peace
- A practising solicitor
- A notary public
- A court commissioner taking affidavits
- Other individuals legally authorised to administer oaths
Can You Witness A Signature Remotely?
Absolutely. In response to the challenges posed by the pandemic and subsequent travel restrictions, remote witnessing has become a well-established practice in 2025. Documents can now be witnessed via secure audiovisual platforms, ensuring that all parties maintain proper identification and transparency during the signing process.
How Does Electronic Witnessing Work?
Electronic witnessing operates by allowing the witness to observe the signing process through a live audio-visual connection. This ensures that the witness can see—and if necessary, hear—the signee as they execute the document, which is then digitally recorded or corroborated.
Once the digital signature is applied, the document can be securely shared online, or even faxed or mailed if required. For enhanced security, many organisations opt to have additional authentication measures, such as digital initials, to further protect against tampering.
Can You Witness An Electronic Signature?
Yes, you can witness an electronic signature. However, it’s essential that this process adheres strictly to the updated guidelines under the Electronic Transactions Act 2000 (NSW), which have been further refined to address modern digital security concerns in 2025.
For more details on secure digital signing practices, our e-signatures guide can provide you with additional insight and best practice recommendations.
How Do Online Contracts Work?
Online contracts function in much the same way as their paper counterparts. They are legally binding documents that have been traditionally signed, but managed entirely through digital platforms. This method allows parties to quickly execute agreements even when they are geographically separated. Many businesses in 2025 use secure cloud-based systems to manage and archive all their legal documents.
For additional guidance on making online contracts secure and enforceable, check out our resource on online shop terms and conditions, which covers many of the same principles applied to digital agreements.
Is An Online Contract Legally Binding?
Yes, an online contract is legally binding as long as it meets all the essential elements of a contract. This includes:
- Offer and acceptance
- Consideration
- Capacity
- The intention of the parties to be legally bound
- Legality of the contract’s purpose
Who Can Sign An Online Contract?
The parties to an online contract, along with any required witnesses, must meet the same legal standards as when signing in person. This means that all parties must sign voluntarily, possess the legal capacity to contract, and comply with all applicable laws and regulations (for instance, provisions in the Corporations Act 2001 if a company is involved).
Legal Age To Sign A Contract
A legal adult—someone aged 18 years or older—is required to sign a contract independently. While minors can also sign agreements, such contracts typically lack enforceability as standard legal obligations. However, contracts for necessities that benefit minors can sometimes be considered valid.
Can I Use E-Signatures?
Yes, e-signatures continue to gain traction in 2025 due to their convenience and efficiency. They eliminate the need for physical travel between signatories, and many digital platforms now feature robust security measures that limit the risk of tampering.
