What legal requirements must a will satisfy in Singapore?
A valid will in Singapore must meet the formal requirements set out in the Wills Act. The testator must be at least 21 years old, except in limited privileged circumstances such as a soldier in actual military service or a mariner at sea, and must have testamentary capacity, meaning they understand the nature of making a will, the extent of their property, and the claims of people who might expect to benefit. The will must be in writing, signed by the testator, or by another person in the testator’s presence and at their direction.
The signature must be made or acknowledged by the testator in the presence of two or more witnesses present at the same time, and each witness must then sign the will in the testator’s presence. These formalities are strict, and a will that does not comply, even in a minor respect, risks being found invalid, which would mean the estate is treated as if that will did not exist.
Beyond formal validity, the testator must also have the mental capacity to understand what they are doing, must not be acting under undue influence, fraud or mistake, and must genuinely know and approve the contents of the will. Where a testator is elderly, unwell, or the will was prepared in unusual circumstances, these substantive requirements often become just as important as the formal ones.
Because an invalid will can lead to an intestacy or revive an earlier will with very different terms, and because the formalities leave little room for error, engaging a lawyer to draft and supervise execution of a will is generally advisable, particularly where the estate, family situation or testator’s health raises any complexity.
Who can act as an executor and witness to a will?
An executor is the person named in a will to administer the estate, apply for a Grant of Probate, and carry out the testator’s wishes. Generally, any adult of sound mind can act as an executor, including a family member, friend, professional adviser or a trust company, and a testator may appoint more than one executor to act jointly, which can be useful for larger or more complex estates. An executor can also be a beneficiary under the will, which is common and does not affect their entitlement.
A witness to a will has a different role, confirming that the testator signed the will, or acknowledged their signature, in the witness’s presence. A witness should be an adult of sound mind who is capable of understanding what they are witnessing and giving evidence about it later if required. Two witnesses are required, and both must be present together when the testator signs or acknowledges their signature.
A person under 21, or someone who lacks the mental capacity to understand the act of witnessing, should not act as a witness, since this can call the validity of the execution into question. Professionals who assist with will preparation, such as lawyers and their staff, commonly act as witnesses given their familiarity with the formal requirements.
Because choosing the right executors and witnesses affects both the smooth administration of the estate and the will’s validity, testators should think carefully about who to appoint. A lawyer can advise on suitable executors given the size and complexity of the estate, and can arrange for properly qualified witnesses at the signing.
Can a beneficiary also witness the will?
A beneficiary can technically witness a will, but doing so is strongly discouraged because of the consequences under the Wills Act. If a witness, or the witness’s spouse at the time of execution, is also a beneficiary under the will, the gift to that beneficiary is generally void, even though the rest of the will remains valid provided it was otherwise properly executed with the required number of qualified witnesses.
This means a beneficiary who acts as a witness risks losing their inheritance entirely, which is rarely what the testator intended. The rule exists to guard against the appearance or reality of a witness having an improper interest in the document they are attesting, and it applies even where there is no suggestion of any wrongdoing.
In practice, this issue often arises inadvertently, for example where a family member helps arrange the signing and signs as a witness without realising they are also named as a beneficiary, or where a spouse of a beneficiary is asked to witness as a convenient second signatory. Once discovered, correcting the position usually requires a new will to be made, since the earlier gift cannot simply be reinstated by explanation after the fact.
Because the consequences of an interested witness can unintentionally defeat a testator’s wishes, and because this is one of the more common drafting pitfalls in DIY wills, testators should choose witnesses who have no beneficial interest in the will and are not married to anyone who does. A lawyer overseeing execution will routinely check for this before the will is signed.
Can a will cover overseas property, digital assets and business interests?
A Singapore will can generally address overseas property, digital assets and business interests, but each raises its own practical considerations. For overseas immovable property, such as land or a house abroad, the law of the country where the property is located usually governs how it is inherited, so a Singapore will may need to be complemented by a will made in that jurisdiction, or at least checked for compatibility with local succession rules, to avoid unintended conflicts or delays.
Overseas movable assets, such as foreign bank accounts or shares in a foreign company, can usually be dealt with under a Singapore will, though the foreign institution or jurisdiction may still require its own recognition of the Singapore grant, sometimes through a process such as resealing, before assets can be released. Digital assets, including cryptocurrency, online accounts and digital records, can be addressed in a will, but access is often practically constrained by platform terms of service and login credentials, so testators increasingly pair a will with a separate, securely stored record of what digital assets exist and how they may be accessed.
Business interests, such as shares in a private company, a partnership interest or a sole proprietorship, can be dealt with in a will, but the constitution of the company, any shareholders’ agreement, or partnership terms may restrict how those interests can be transferred, which should be checked alongside the will to ensure consistency.
Because overseas assets, digital assets and business interests each carry their own legal and practical complications, testators with such assets should seek advice from a lawyer experienced in cross-border and business succession planning to ensure the will works as intended.
How should a will address guardianship of minor children?
A will can appoint a guardian to take over parental responsibility for minor children if both parents pass away, or in some circumstances where the appointing parent is the sole surviving parent, under the framework set out in the Guardianship of Infants Act. This appointment allows parents to choose, in advance, who they would want to raise their children rather than leaving the matter to be decided without their input.
A guardianship appointment made in a will generally takes effect once the circumstances triggering it arise, such as the death of both parents, though the court retains the power to review, confirm or vary the arrangement if it is disputed or if it is not in the best interests of the child. Where the other parent survives, that parent’s own parental rights generally continue unless a court decides otherwise, so a guardianship clause in a will complements rather than automatically overrides the surviving parent’s role.
Good practice includes naming at least one alternate guardian in case the first choice is unable or unwilling to act, and considering whether to leave a separate, non-binding letter of wishes setting out preferences on the children’s upbringing, education and values, which can guide the appointed guardian even though it does not have the same legal force as the will itself.
Because guardianship decisions affect the wellbeing of children directly, and because the legal framework requires careful drafting to work as intended, parents of minor children should discuss guardianship provisions with a lawyer when preparing or updating their wills.
Does a will control CPF savings, insurance nominations and jointly owned property?
No, a will generally does not control these three categories of assets, which is one of the most common misunderstandings in estate planning in Singapore. CPF savings do not form part of the estate distributed under a will. Instead, they are distributed according to a separate CPF nomination made directly with the CPF Board, or, if no valid nomination exists, they are distributed by the Public Trustee’s Office broadly along the lines of the intestacy rules.
Insurance policy proceeds are similarly often unaffected by a will where a valid nomination has been made, particularly a trust nomination made under the Insurance Act, since such nominations typically pass the proceeds directly to the named nominee outside the estate. Where no nomination exists, or the nomination is not a trust nomination, the treatment can differ, so it is worth checking each policy’s specific nomination status rather than assuming the will covers it.
Jointly owned property held as joint tenants passes automatically to the surviving joint owner or owners by the right of survivorship, regardless of what the will says, since the deceased’s interest does not form a separate asset capable of being left by will. Property held as tenants in common is different, since each owner’s distinct share does form part of their estate and can be dealt with under their will.
Because CPF savings, insurance nominations and joint property often sit outside the will entirely, testators should review and coordinate these separately with their overall estate plan, and a lawyer can help ensure the whole picture, rather than just the will, reflects the testator’s wishes.
Can a person write their own will without engaging a lawyer?
Yes, it is legally possible to write a valid will without a lawyer, provided the formal requirements under the Wills Act are properly met, including the required signature and two witnesses present at the same time. Various will-writing kits and templates are available, and for a very simple estate with straightforward wishes, some people do prepare their own wills.
However, DIY wills carry meaningful risks. Common problems include improperly executed signatures or witnessing, ambiguous or contradictory clauses, failure to appoint substitute executors or guardians if the first choice cannot act, unintended revocation of an earlier will, and a failure to address matters such as overseas assets, business interests or CPF and insurance nominations, which a will does not automatically cover. These issues often only come to light after the testator has passed away, when it is too late to fix them.
The risk of error is generally higher where the family situation is more complex, such as blended families, estranged relatives, minor or vulnerable beneficiaries, business ownership, or significant overseas assets, since these situations require careful and sometimes bespoke drafting to achieve the intended outcome and to reduce the risk of a successful challenge later.
Because the cost of professional drafting is often modest compared with the cost, delay and family friction that can follow from a poorly drafted or invalid will, engaging a lawyer is generally advisable, particularly for anyone with more than a very simple estate or family structure.
Where should the original signed will be stored?
The original signed will should be kept somewhere safe, secure and, importantly, findable by the executor or family after the testator’s death, since a will that cannot be located can cause serious delay and, in some cases, lead to the estate being administered as if the testator had died intestate. Common options include a solicitor’s safe custody service, where the lawyer who prepared the will retains the signed original, a bank safe deposit box, or a fireproof safe at home.
Singapore also has a voluntary wills registry service that allows a person to register the fact and location of their will, without the registry holding the physical document itself, which can help executors and family members locate the will after death even if they are unsure where the original is kept. Registering a will’s existence in this way is a useful complement to, rather than a substitute for, safely storing the original document.
Whichever storage method is chosen, the testator should tell their executor, or a trusted family member, where the will is kept and how to access it, since even a perfectly valid will serves little purpose if no one knows it exists or can find it when needed.
Because the consequences of a lost or unfound will can be significant, testators should treat safe storage and clear communication about its location as an essential part of the will-writing process, and a lawyer can advise on the most suitable arrangement for the testator’s circumstances.
When should a will be reviewed or replaced?
A will should be reviewed whenever a significant life event occurs, since circumstances can change in ways the original will did not anticipate. Marriage is particularly important, because in Singapore marriage generally revokes an existing will automatically, unless the will was expressly made in contemplation of that marriage, meaning a will made before marrying may need to be replaced entirely rather than simply updated.
Divorce does not automatically revoke a will in the same way, but it can affect specific provisions, such as an appointment of the former spouse as executor or a gift to them, which may be treated as if the former spouse had passed away before the testator, depending on the applicable provisions. Other triggers for review include the birth of children, the death of a named executor, guardian or beneficiary, acquiring significant new assets such as a business interest or overseas property, and moving to live overseas.
Even without a specific triggering event, it is good practice to review a will periodically, since family relationships, asset values and personal wishes can shift gradually over time in ways that are easy to overlook until the will is read again with fresh eyes.
Because an outdated will can fail to reflect a testator’s current wishes, or in the case of marriage may be automatically revoked without the testator realising, reviewing a will after any major life change, and periodically in any event, is important. A lawyer can help assess whether a full replacement or a more limited update is appropriate.
How can a will be revoked or changed?
A will can be revoked in several recognised ways. The most common is by making a later will or codicil that includes a clause revoking all earlier wills, which is why it is important to be clear about what a new will is intended to replace. A will can also be revoked by a written declaration of an intention to revoke, executed with the same formalities as a will, or by the testator, or someone in the testator’s presence and at their direction, physically destroying the will, such as by burning or tearing it, with the clear intention of revoking it.
Marriage also automatically revokes an existing will in Singapore, unless the will was made in contemplation of that specific marriage, which is a frequent and sometimes overlooked consequence for testators who marry after making a will.
Where a testator wants to make changes rather than revoke the will entirely, this can be done through a codicil, which is a formal document that amends specific parts of the will and must be executed with the same signing and witnessing formalities as the will itself. For more substantial changes, making an entirely new will is usually simpler and safer than relying on multiple codicils, which can become difficult to interpret together.
What should never be done is informally crossing out or writing changes directly onto the original signed will, since alterations made this way are generally not effective and can create uncertainty or disputes about the testator’s true intentions. A lawyer can advise on whether a codicil or a new will is the more appropriate way to make a desired change.
Does making a will also cover my CPF nomination, or do I need to arrange that separately?
Making a will does not cover your CPF nomination, and the two must be arranged entirely separately. CPF savings do not form part of the estate that a will governs, so even a comprehensive, carefully drafted will has no effect on how your CPF savings are distributed after you pass away.
To determine who receives your CPF savings, you need to make a CPF nomination directly with the CPF Board, which can typically be done through their nomination service, naming the person or people you want to receive your CPF savings and in what proportions. If no valid nomination is made, your CPF savings are distributed by the Public Trustee’s Office broadly following rules similar to intestate succession, which may not reflect what you would have wanted.
Because a will and a CPF nomination are governed by entirely separate legal frameworks, having one does not substitute for the other, and it is a common misconception for people to assume that writing a will automatically takes care of their CPF savings as well. Both should be reviewed and kept up to date, particularly after major life events such as marriage, divorce or the birth of children, since a CPF nomination, like a will, does not automatically update itself.
Because overlooking the CPF nomination is such a common and easily avoidable gap in estate planning, testators should treat arranging or updating their CPF nomination as a distinct and equally important task alongside making or updating their will.
