For many individuals, the act of signing a Will feels final — a decisive step towards ensuring that loved ones are cared for and that one’s intentions are honoured. Yet, few realise that even a properly executed Will can later lose its legal effect under the law. In some instances, this happens without any conscious intention to revoke it. Under Singapore law, a Will can simply cease to exist in the eyes of the law, and this process — known as revocation — is governed by specific provisions of the Wills Act 1838 (the “Act”).

Revocation can occur in a number of ways: by marriage, by the execution of a subsequent Will, by an express declaration of revocation, or even by the physical destruction of the Will itself. The effect, however, is always the same — the earlier Will becomes void, and the estate may consequently be administered under a completely different distribution framework.

In this article, we examine how the Act treats revocation, highlight the most common misconceptions surrounding it, and discuss how such oversights can have serious — and sometimes irreversible — consequences.

Revocation by a Later Will or Declaration

The most common and straightforward form of revocation is by the execution of a later Will or codicil. Under Section 15(b) of the Act, a Will may be revoked by another Will or by a codicil executed in accordance with the same formalities prescribed under Section 6 — namely, the document must be in writing, signed by the testator, and witnessed by two persons present together at the time of signing.

This means that whenever a new Will is properly executed, the earlier Will is automatically revoked, unless the later Will expressly preserves it in whole or in part. Problems arise, however, when individuals attempt to “update” their Wills informally — for example, by signing a home-printed document without witnesses, or by leaving behind an unsigned note labelled “New Will.” Such documents fail to satisfy the statutory formalities and are therefore ineffective as instruments of revocation.

Revocation by Marriage

A lesser-known but equally significant form of revocation arises under Section 13 of the Act. This section provides that a marriage automatically revokes a Will, unless the Will was made in contemplation of that marriage (see Section 13(2)).

This statutory rule often catches people unaware. The law presumes that marriage fundamentally alters a person’s obligations and relationships, and thus any prior testamentary dispositions should no longer stand. Consequently, when a person marries after making a Will, that earlier Will is revoked by operation of law.

For example, consider a woman who executes a Will in 2018 naming her siblings as beneficiaries. She later marries in 2021 but does not update her Will. If she passes away thereafter, her 2018 Will is automatically revoked. In the absence of a new Will, her estate will be distributed under the Intestate Succession Act, which generally prioritises the surviving spouse and children.

This outcome may be entirely contrary to her intentions, potentially creating friction between her new spouse and her family members. The lesson is clear: marriage automatically voids a Will unless that Will was expressly drafted in contemplation of marriage. This should be stated clearly within the document itself to preserve its validity post-marriage.

Revocation by Destruction and Presumption of Revocation

Revocation may also occur through the physical destruction of the Will by the testator. Under Section 15(d) of the Act, a Will is revoked when it is burned, torn, or otherwise destroyed by the testator — or by someone acting under the testator’s direction — with the intention of revoking it. Both the act of destruction and the intention to revoke must be proven.

This provision may appear simple, but its implications can be far-reaching. If a Will known to have existed cannot be found after the testator’s death, the court may apply what is known as the presumption of revocation. In such cases, the absence of the original document is taken as evidence that the testator intentionally destroyed it with the intention to revoke. Even when a photocopy or digital scan exists, probate may be refused unless there is strong, credible evidence rebutting this presumption — such as testimony from witnesses confirming that the testator intended the copy to serve as the operative Will or that the original was accidentally lost or destroyed.

These cases are more common than many expect. Elderly testators often store Wills in drawers, safes, or other private locations, and the documents are sometimes misplaced. Without the original, courts are left with little choice but to presume revocation — leaving the estate to be distributed under intestacy. Proper safekeeping of original Wills, and clear communication with executors, are therefore crucial parts of estate planning.

Common Misconceptions

One of the most prevalent misconceptions is that divorce automatically revokes a Will. In fact, the Act is clear that it does not. A divorce has no legal effect on an existing Will. A former spouse who remains named as executor or beneficiary will continue to inherit unless the testator executes a new Will after the divorce. This misconception has led to numerous instances where ex-spouses have unexpectedly benefited from estates years after the marriage was dissolved.

Another misunderstanding concerns informal alterations. Section 6(2) of the Act stipulates that any alteration to a Will must be executed with the same formalities as the original. Casual edits — such as crossing out words, stapling additional pages, or making handwritten notes — do not constitute valid amendments. Such alterations are ignored during probate, and the unamended version of the Will is admitted instead.

Finally, many assume that digital or scanned copies of Wills carry legal weight. They do not. Under
Section 6, a Will must be physically signed and witnessed by two persons present together. Singapore has not yet adopted legislation recognising electronic Wills or remote witnessing. An email or digitally signed document, no matter how clear, does not satisfy the statutory requirements.

The Consequences of Unintended Revocation

When a Will is revoked but not replaced, the testator is deemed to have died intestate. The estate is then distributed according to the rigid hierarchy set out in the Intestate Succession Act, which leaves no room for personal discretion. This can have harsh consequences for unmarried partners, stepchildren, or dependants who fall outside the statutory framework.

Beyond these legal complexities, the emotional cost is often immense. Families may discover only after a loved one’s death that the Will they believed existed has no legal effect. What follows is a costly, protracted, and emotionally draining process of distributing the estate under intestacy.

Preventing the Pitfalls

Avoiding these problems begins with awareness and regular review. Every major life event — marriage, divorce, the birth of a child, relocation, or the acquisition of new property — should trigger a review of one’s Will. If a Will is made in contemplation of marriage, this should be expressly stated in its preamble so that it survives marriage under Section 13(2).

Any amendment, however minor, must be executed formally with two witnesses in compliance with
Section 6. Equally important is the safekeeping of the original document. The destruction or loss of the only signed copy may lead the court to presume revocation.

Conclusion — Ensuring Continuity of Intention

Revocation may seem like a minor technicality, but in practice, it determines whether a person’s final wishes ever take effect. At SMTP, our lawyers regularly assists clients in identifying and mitigating latent revocation risks under the Wills Act.

We help clients:

• Draft Wills that are “made in contemplation of marriage” and therefore protected against automatic revocation;
• Conduct periodic estate plan audits to ensure that major life events do not invalidate existing Wills;
• Align Wills, CPF nominations, insurance designations, and trust structures to avoid conflict and inconsistency; and
• Offer custodial safekeeping services to secure original Wills and eliminate the risk of presumed revocation by loss or destruction.

A Will is not a static document — it is a living instrument that must evolve as life changes. Understanding how and when a Will can be revoked ensures that one’s legacy remains intact, unbroken by technicalities or unintended legal consequences. With careful review and professional guidance, your final wishes can remain exactly as you intended — valid, enforceable, and preserved.
