3 Steps to a Valid Will in Singapore: Formalities, CPF, SAL & HNW Prep
A valid will in Singapore must be in writing, signed by the testator at the foot or end of the document, and signed by two witnesses who are both present at the same time and who subscribe the will in the testator’s presence. The testator must be 21 or older and of sound mind. Once those boxes are checked, your three immediate priorities are confirming your witnesses meet the legal criteria, securing the original document, and reviewing your CPF nomination separately.
TL;DR:
Witnesses must be at least 21 years old, mentally capable, and cannot be a beneficiary or their spouse to avoid invalidating the will.
CPF savings do not form part of the estate and require a separate nomination even if a will exists.
Electronic signatures are not recognized under Singapore law, requiring physical signing and in-person witnessing for validity.
Proper storage, SAL registration, and current nomination forms significantly reduce the risk of will disputes or revocation.
Complex estates or blended families benefit from specialist review and tailored drafting to ensure the will functions as intended.

Formal requirements for a legally valid will under the Wills Act
The Wills Act sets out the execution rules that every will in Singapore must follow. The document must be in writing, signed by the testator (or by someone else in the testator’s presence and at their direction), and that signature must appear at the foot or end of the will. Two or more witnesses must then sign in the testator’s presence, and they must both be present at the same time when the testator signs. Skipping any one of these steps can render the whole document void.
Age and mental capacity matter just as much as paperwork. A testator must be at least 21 years old, of sound mind, and acting voluntarily rather than under pressure from a family member or caregiver.
Witnesses carry their own restrictions. A beneficiary named in the will, or that beneficiary’s spouse, should never act as a witness, since doing so can void the gift intended for them even if the rest of the will stands. Choosing neutral witnesses, such as colleagues or friends with no stake in the estate, avoids this trap entirely. We also see testators lose validity through avoidable missteps:
Signing pages separately instead of in one sitting with both witnesses present.
Using a witness who is under legal age or lacks mental capacity to understand what they are attesting.
Relying on electronic signatures, which Singapore law does not currently recognize for wills, as explained in our piece on digital signatures and will execution.
Leaving the signature in the margin or on a separate page rather than at the foot or end of the text.
Pro Tip: Before filing your will away, read through the signing page and confirm both witnesses’ signatures, printed names, and the date all appear together on the same page as yours.
What a will cannot control: CPF, joint tenancy and beneficiary nominations
A will only governs assets that form part of your estate, and several common holdings fall outside that definition entirely. Missing this distinction is one of the most frequent planning gaps we encounter.
CPF savings never form part of your estate. They pass according to a separate CPF nomination, and making one is free. Without a nomination, your CPF savings go to the Public Trustee’s Office, which distributes them under intestacy rules and deducts an administrative fee.
Jointly owned property often bypasses your will. Under a joint tenancy, the surviving owner automatically inherits the full property interest through the right of survivorship, regardless of what your will says. A tenancy-in-common arrangement, by contrast, lets your share pass according to your will.
Insurance payouts and investment accounts follow their own nomination forms. Insurance nominees and CPF Investment Scheme beneficiaries are determined by the forms filed with each provider, not by your will.
Treat your will as one piece of a larger puzzle rather than the whole picture. Pull your CPF nomination, insurance nominee forms, and property title documents at the same time you review your will, and make sure none of them contradicts what you intend for your estate.
Registering and storing your will in Singapore
Finding a will after someone dies is often harder than drafting one in the first place, which is why the Singapore Academy of Law (SAL) Wills Registry exists. The registry works as a confidential locator service: it records where your will is kept so your executor can find it, but it does not store or validate the document itself. SAL also offers a digital deposit option through participating law firms, with complimentary deposit windows announced periodically for added security.
Registration never replaces the need for a safely stored original. Common custody options include:
Leaving the original with the law firm that drafted it.
Storing it in a bank safe deposit box.
Handing it to your appointed executor for safekeeping.
If the original cannot be located when you pass away, the law may presume it was revoked, which forces your family into a harder probate process with a higher evidentiary burden. That single risk is the strongest argument for depositing your will’s location with SAL rather than leaving your executor to guess.
To deposit with SAL, you or your lawyer submit the registration details along with your executor’s contact information, so the registry can direct inquiries to the right person when the time comes. Tell your executor directly, in writing, where the original sits and how to request the SAL record.
Executor and probate basics: what the court will need and typical timelines
Your executor manages estate assets, settles outstanding debts, and applies for the Grant of Probate that gives them legal authority to act. Choosing the right person for this role matters as much as drafting the will itself.
Gather the required documents. Courts typically ask for the original will, the death certificate, and a schedule of the deceased’s assets and liabilities.
Present the original will at the Probate Counter. The court verifies the original before returning it to the executor, and a copy generally will not suffice without strong supporting evidence.
Expect timelines tied to complexity. Probate timelines vary depending on case complexity, with straightforward cases processing faster and more complex or contested estates taking longer. The Family Division of the High Court is involved for estates exceeding certain value thresholds.
Appoint wisely. A spouse, adult child, or trusted friend can serve as executor, but larger or more complex estates often benefit from a professional or corporate executor who can reduce family conflict and administrative strain. Our complete guide to choosing an executor walks through the tradeoffs in more detail, and our step-by-step probate guide covers the filing process itself.
Pro Tip: Name a backup executor in your will in case your first choice is unavailable, predeceases you, or declines to serve.
When to seek specialist drafting or trustee services
Formal validity, meaning correct signing and witnessing, is only half the job. Essential validity is the harder half: making sure the will actually functions as intended once business interests, foreign property, or blended families enter the picture. A document that passes every formality can still fail the people it was meant to protect if the drafting does not anticipate how the estate will actually unwind.
Certain red flags should prompt a specialist review rather than a template:
Ownership stakes in a private business that need a succession or buyout plan.
Property or investments held outside Singapore.
Blended families where children from different relationships need distinct provisions.
A desire to control how and when beneficiaries receive funds, which usually calls for a testamentary trust.
Estates large or complex enough to warrant a corporate executor instead of a family member.
Formal compliance tells you a will is legally signed. It says nothing about whether the plan behind it actually works for a complex estate.
If any of these apply to you, the practical next steps are a document review, tailored drafting for a will or trust, and coordination between your CPF nomination and your broader estate plan before you finalize anything.
Advance Medical Directive (AMD) is a separate document with different formalities
A will governs what happens to your estate after death. An Advance Medical Directive governs a different question entirely: whether you want extraordinary life-sustaining treatment withheld if you become terminally ill and unconscious. The two documents are often confused, but they follow completely separate rules.
An AMD requires two witnesses, and one of them must be a doctor, a stricter standard than the two lay witnesses a will requires. The directive then has to be registered with the Registrar of Advance Medical Directives at the Ministry of Health before it carries legal weight. Neither witness can have a financial interest in your death, which rules out beneficiaries and close family members with a stake in your estate.
The Advance Medical Directive Act also specifies that an AMD only takes effect once a panel of doctors certifies that you are terminally ill and unable to express your wishes. It does not cover other end-of-life decisions, such as organ donation preferences or who manages your finances if you lose capacity but remain alive, so it works alongside your will rather than replacing any part of it.
If end-of-life planning matters to you, treat the AMD as its own project with its own paperwork, rather than something you can fold into your will’s existing signature page.
Revocation and alteration of a will under Singapore law
A will is never permanently fixed. Under the Wills Act, you can revoke an existing will by executing a new one, by a written declaration signed with the same formalities as a will, or by physically destroying the document with the clear intention of revoking it.
Marriage automatically revokes a prior will in Singapore, which catches many people off guard if they draft a will while single and then marry without updating it. Divorce, by contrast, does not automatically revoke a will, so an ex-spouse named as a beneficiary may still inherit unless you actively amend the document.
Minor changes do not require a full rewrite. A codicil, a short supplementary document executed with the same signing and witnessing formalities as a will, can update a specific clause, such as swapping an executor or adjusting a bequest, without touching the rest of the document. What you should never do is hand-write a correction onto an existing signed will and initial it informally, since alterations made after execution without proper attestation can be disregarded or can cast doubt on the whole document.
Review your will after any major life event: marriage, divorce, the birth of a child, a significant change in assets, or the death of a named executor or beneficiary. A will that accurately reflected your wishes five years ago may no longer match your family situation or your estate today.
Common reasons for a will to be declared invalid
Most invalid wills fail for predictable reasons, and nearly all of them are avoidable with careful execution. Incorrect witnessing tops the list: using a beneficiary or their spouse as a witness, having witnesses sign at different times, or using only one witness instead of two all create grounds to challenge the document.
Capacity issues come next. A will signed by someone who lacked the mental capacity to understand what they were doing, or who was under 21 at the time, can be struck down regardless of how clearly it was written. Undue influence is a related problem: if a family member or caregiver pressured the testator into specific terms, a court can set the will aside even if the signing itself followed every formal rule.
Improper signature placement causes more disputes than people expect. A signature that appears above the final clause rather than at the foot or end of the document, or one added on a separate page not clearly part of the will, can undermine the entire document’s validity under the Wills Act.
Lost or missing originals create a different kind of problem. Courts may presume a will was revoked if the original cannot be produced, and while secondary evidence such as a copy can sometimes be admitted, the burden of proof is considerably higher than simply handing over the signed original. This is the strongest practical argument for depositing your will’s location with the SAL Wills Registry rather than leaving its whereabouts to chance.
Impact of intestacy when a will is invalid or absent
When a will is invalid or never existed, Singapore’s Intestate Succession Act decides who inherits, and that formula rarely matches what someone would have chosen for themselves. Assets are distributed according to fixed shares among a spouse, children, and sometimes parents or siblings, with no room for personal wishes, charitable gifts, or special provisions for a child with particular needs.
Intestacy also means the court appoints an administrator rather than honoring a testator’s choice of executor, which can hand control of the estate to someone the deceased would never have selected. The process itself tends to move slower than probate under a valid will, since the court has to work through statutory default rules rather than following clear instructions.
For blended families, unmarried partners, or anyone who wanted to leave something to a friend, a cause, or an organization outside their immediate family, intestacy is often the worst-case outcome. Unmarried partners receive nothing under the default rules no matter how long the relationship lasted, and stepchildren who were not legally adopted are excluded entirely. A properly executed will is the only way to guarantee these groups receive anything.
Role and importance of witnesses: disqualifications and conflicts of interest
Witnesses exist to confirm that the testator genuinely signed the will, voluntarily and with capacity, so their role carries more legal weight than people often assume. The Wills Act requires two witnesses, both present at the same time as the testator’s signature, and both must then sign themselves in the testator’s presence.
Certain people should never serve as witnesses. A beneficiary named in the will cannot act as a witness, because doing so voids the gift intended for them, even though the rest of the will usually remains valid. The same rule extends to a beneficiary’s spouse, since the financial interest runs through the marriage. Witnesses under 21 or lacking the mental capacity to understand what they are attesting also fail to meet the legal standard.
Practically, the safest witnesses are people with zero financial stake in the estate: colleagues, neighbors, or professional staff such as a lawyer’s office staff who assist with the signing. Avoid using family members entirely where possible, even those who are not named beneficiaries, since disputes sometimes arise over perceived influence even when no legal conflict technically exists.
Digital or electronic wills status and recognition in Singapore
Singapore law does not currently recognize electronic signatures or fully digital wills as meeting the Wills Act’s execution requirements. The statute calls for a physical signature by the testator and physical signatures from two witnesses present in person at the same time, a standard that video witnessing or e-signature platforms do not satisfy.
This gap surprises people who assume that because so much of Singapore’s legal and financial infrastructure has moved online, wills must have followed. They have not. A will signed over a video call, or one bearing a typed or scanned signature instead of a wet-ink one, risks being thrown out entirely during probate, leaving an estate to fall under intestacy rules. Our analysis of why digital signatures cannot execute a will in Singapore goes through the specific failure points in more detail.
What has moved online is the storage and administration side, not the execution itself. The SAL Wills Registry allows digital deposit of a will’s details and, through participating law firms, digital copies for safekeeping, but the underlying document still has to be physically signed and witnessed first. Until the law changes, treat the signing ceremony itself as strictly analog, no matter how convenient a digital shortcut might seem.
Common failures and practical priorities
The wills that cause the most trouble in probate rarely fail for dramatic reasons. They fail because a witness was a beneficiary’s spouse, the original went missing in a drawer nobody checked, or a CPF nomination was never updated after a divorce. Correct witnessing, secure storage, a SAL deposit, and a current CPF nomination together close most of the gaps that turn a straightforward estate into a contested one. If your estate includes a business, overseas property, or a blended family, get a specialist review early rather than after a dispute has already started.

FAQ
What is the best way to write a simple will?
A simple will needs to be in writing, signed by you at the foot or end of the document, and signed by two witnesses who are both present together when you sign. Keeping the language plain, naming one primary executor and a backup, and avoiding beneficiaries as witnesses covers most of what a straightforward estate requires.
What is an executor of a will?
An executor is the person you appoint to carry out your will’s instructions after you die, including managing assets, paying off debts, and applying to the Family Justice Courts for a Grant of Probate. Many people choose a spouse, adult child, or close friend, though larger or more complex estates often benefit from a professional or corporate executor.
How much does a will cost in SG?
Costs vary widely depending on complexity and whether you use a template, a lawyer, or a specialist firm. Through our own services, a Comprehensive Will runs from $1,250 to $1,900 one-off, while more complex structures such as a Business Value Protection Trust start from $8,000.
Who can be a witness to the will?
A witness must be at least 21 years old and mentally capable of understanding what they are attesting, and they cannot be a beneficiary named in the will or that beneficiary’s spouse. Both witnesses need to be present together when you sign, then sign the will themselves in your presence.
