Signing a will may seem simple, but in Malaysia, the smallest mistake can make the entire document invalid. Whether you are preparing your first will or updating an existing one, understanding the correct signing process is essential. This guide explains the legal requirements under Malaysian law, the role of witnesses, the signature rules, and the common errors that often lead to disputes.
If you prefer expert guidance, you may also refer to our professional will writing services for a compliant, carefully drafted will that meets all legal standards.

Many of Malaysians believe that writing a will is enough, but the truth is this:
A will only becomes legally valid when it is signed correctly – by the testator and the witnesses — following the exact rules under the Wills Act 1959.
A properly signed will ensures:
Your wishes are followed
Your assets are distributed smoothly
Your family avoids unnecessary disputes
Your estate avoids delays during probate
In fact, incorrect signing is one of the top reasons Malaysian wills are rejected in court. That is why understanding how to sign a will correctly in Malaysia is crucial for anyone planning their estate.
Actually, to ensure your will is recognised as valid under Malaysian law, the signing process must meet these criteria:
Your signature should appear at the bottom of the main content. This helps prevent allegations that additional pages were added later.
You must sign the will free of pressure, influence, or coercion.
Your signature must show clear intention that you are confirming the document as your will.
This is the most important legal requirement. Both witnesses must:
Be physically present when you sign
See you sign the will
Sign the will in your presence
Both witnesses must also sign on the same document, usually on the final page.
Remember, for those drafting their wills for the first time, our article on how to write a will in Malaysia provides deeper guidance on legal terminology and structure.
While the testator can be anyone aged 18 and above (non-Muslim), the witnesses must follow strict rules.
Any competent adult aged 18 and above
Malaysian citizen or permanent resident (recommended, but not legally mandatory)
Sound mind and capable of understanding their role
Must not be a beneficiary of the will
Beneficiaries named in your will
Beneficiary’s spouse
Anyone who stands to gain from the will
Persons lacking mental capacity
Persons not physically present during signing
If your beneficiary signs as a witness, the will may still remain valid, but that beneficiary will lose their entitlement. Many Malaysians are not aware of this rule, which is why professional guidance is so important when preparing a will.

Here is the proper procedure for signing a will in Malaysia, including the witnessing sequence:
Ensure both witnesses are present at the same time. They must understand their role and confirm they are not beneficiaries.
You (the testator) must sign the will before they do.
Your signature should appear at the end of the document.
They must sign:
In your presence
On the final page (and, ideally, initial other pages)
The witnesses acknowledge that:
They saw you sign
They are signing voluntarily
They understand they are not beneficiaries
A signed will must be stored in a secure place. Many families lose their wills or damage them by accident.
To avoid this risk, our will custody service protects original documents from theft, loss, or fire.
Answer is – No. Actually, under the Wills Act 1959, digital signatures, electronic signing platforms, or scanned signatures are NOT validfor wills.
Your will must be physically signed in ink by both the testator and the witnesses.
This means:
No e-signature
No DocuSign
No scanned copy
No electronic witnessing
Only handwritten, original signatures are accepted in Malaysian courts.
The truth is, even a small errors, eventually can make a will invalid or open it to legal challenge. Below are the most frequent/common mistakes Malaysians make:
This is the #1 error. A beneficiary cannot witness a will.
All signatures must occur in each other’s presence. Signing separately invalidates the witnessing.
If pages can be altered, the court may question authenticity.
Any changes after signing must be re-witnessed.
The signature must be at the end to certify the contents.
Not recognised under Malaysian law.
Two witnesses are mandatory.
At some point, If you uncertain, our writing a will in Malaysia guide explains the proper process in detail.
Most importantly, if your will is incorrectly signed or witnessed, the consequences may include:
The court may decide it cannot be accepted for probate.
Distribution will follow the Distribution Act 1958 — not your wishes.
Especially if they incorrectly act as witnesses.
Unclear wills are the biggest cause of estate-related conflict.
An improper signature can extend probate by months or years.
Ultimately, this is why Malaysians increasingly choose a trust company to handle their will writing, ensuring proper signing, witnessing, and custody.
You should consider re-signing or updating your will if:
You got married or divorced
You purchased property
You started a business
You had a new child
Your beneficiaries changed
Your witness is now deceased
You want to add new instructions
Every update requires a new signature and new witnesses.
Alternatively, a codicil (amendment) may be used, but it must also follow the same signing rules as a will.
