In Singapore, the Intestate Succession Act 1967 is the law that decides who inherits your estate if you die without a valid will. It commenced on 2 June 1967 and remains in force today.
"Intestate" simply means dying without a will. The Act also covers partial intestacy, which is the situation in which one leaves a will which does not comprehensively cover all property in one's estate.
In simple terms, the Act creates a fixed order of inheritance, bound by preset rules. It applies a formula based purely on family relationships, based on the state's conception of the hierarchy of such relationships. Because of this, the formula frequently produces outcomes which are commonly considered problematic and unexpected for the majority of individuals.
Under the Act, all movable property (bank accounts, shares, cars etc.) is distributed based on where the individual is domiciled. Immovable property (land, property etc.) located in Singapore is governed by the Act regardless of where the deceased was domiciled.
One crucial point is that the Act does not apply to Muslims, whose estates are distributed according to Muslim inheritance law under section 111 of the Administration of Muslim Law Act.
Section 7 of the Act contains nine rules, applied in strict order. The estate is distributed only after debts, funeral expenses, and administration costs are paid.
Based on the Act, the hierarchy of distribution is as follows:
Each class must be exhausted before the next is reached. If you leave a spouse and a child, your parents and siblings receive nothing — regardless of circumstances. The law establishes a clear hierarchy which must be followed in lockstep.
B. A Spouse is only recognised under a legally binding marriage
Under the law, a spouse needs to be legally married to the deceased to qualify for distributions under the Act. In situations where a spouse is spearated but not yet legally divorced, the spouse would still take their full share of your estate under the Act.
C. Grandchildren survive as a branch of your children's lineage
If one of your children dies before you but leaves children of their own, that branch of the family is not cut off. Your deceased child's share passes down to their own children, who divide it between them. Lawyers call this per stirpes — distribution by branch, not by head.
So if you have three children and one has predeceased you leaving two children, the estate is still divided into three parts: two children take one-third each, and your two grandchildren share the remaining third.
D. Children qualify for distribution only if they are born inside marriage or are legally adopted
Under the Act, biological children have equal footing with legally adopted children. All children born outside marriage do not inherit under the Act. This has been confirmed by the Singapore courts on multiple occassions (e.g. AAG v Estate of AAH [2010] 1 SLR 769).
Stepchildren do not inherit unless they have been legally adopted.
E. All relatives rank equally regardless of whether they are on the maternal or paternal side
Section 6 of the Act ranks relatives on both sides equally. Half-blood relatives rank immediately after whole-blood relatives.
As the Act applies a standard formula, it often creates challenging situations where the likelihood of disputes amongst your loved ones increases exponentially. Without a valid Will and proper associated legacy planning, a number of common issues may arise
A. A large part of your wealth may never reach your estate
A valid will and proper estate planning goes a long way to protecting the needs of your surviving loved ones. Without proper provisions, there are major asset types which are bypassed entirely by the Intestate Succession Act. For example, CPF monies are actually not considered part of one's estate - without a nomination, these monies would be distributed by a Public Trustee under a separate process.
Property held as joint tenants is passed automatically to the surviving joint tenant by right of survivorship, and never enters the estate. This situation frequently creates challenges and conflicts amongst a surviving spouse and children. On the other hand, property held as tenants-in-common actually forms part of an estate to be distributed. These distinctions are fundamentally important.
B. Unmarried partners and non-legitimate children do not inherit anything under the Law
Because the Act follows a strict hierarchy based on legally binding familial ties, without a Will, an unmarried partner and non-legitimate children are not entitled to any distributions. Moreover, one would also not be able to donate any part of their estate to charity nor provide for close friends and companions, no matter how strong their moral claims to your estate may be.
C. The standard distribution formula splits the estate between a spouse and children, which may create conflicts
When one passes with a surviving spouse and children, your spouse only takes half of the estate, while your children will split the remaining 50% equally. As the home is typically the primary asset in an estate, assuming it is held in one's sole name, conflicts amongst the surviving spouse and children can complicate ownership and eligibility rules, especially for HDBflats.
D. Dependents do not have anything set aside for their needs automatically
The Act does not discriminate based on needs, and only uses a hierarchy of familial ties to distribute an estate. As such, a financially independent adult child and a disabled dependent child would receive identical shares. While certain dependents may apply to the cout for relief under the Inheritance (Family Provision) Act 1966, this requires litigation, costs, and time
E. Administration of an estate is slower and more restrictive without a Will
Without a valid Will, there would be no executor for an estate. In Intestate Succession, an individual would need to apply to the Family Justice Courts for a Grant of Letters of Administration before any asset can be dealt with. This may require sureties and the process is typically longer than a straightforward probate application. For smaller estates, the Public Trustee can administer certain assets, such as bank deposits and SGX-listed shares, but only if the estate is worth S$50,000 or less (excluding Depedants' Protection Scheme payouts).
F. Partial Intestacy is a risk which cannot be ignored
Most individuals do not update their Wills periodically. An old will which excludes assets acquired later, or which fails because of lapses, would leave those assets to be distributed under Intestate Succession. This means that the lack of a comprehensive, updated, and refreshed will (including a latest schedule of assets) can easily create situations where a portion of assets would be distributed under the Act.
Reviewing and writing a new will after major life events is hence underappreciated and extremely important. Moreover, under Section 13 of the Wills Act, marriage actually revokes an existing will unless that will was made in contemplation of marriage. As such, there are actually a large number of individuals with invalid wills who are not even aware that their wills have already been revoked under Singapore law.
The Intestate Succession Act is rigid, blind to circumstances, and recognises a much narrower group of people than most families would. As such, it has a propensity to create conflicts and challenges for your loved ones after your passing.
A valid will reflects your choices and better protects your loved ones based on their potential needs, and is fully customisable based on your preferences.
