Best Estate Planning Guide for Unmarried Couples in Singapore

If you're in an unmarried partnership in Singapore, estate planning isn't optional — it's the only thing standing between your partner and complete legal disinheritance. Under the Intestate Succession Act, unmarried partners have zero inheritance rights. If your partner dies without a will, you receive nothing. Their estate goes entirely to their blood relatives — parents, siblings, or more distant kin — regardless of how long you've been together, whether you share a home, or whether you've been financially interdependent for decades.

This isn't a technicality or an edge case. It's the default legal outcome for every unmarried couple in Singapore who hasn't explicitly planned around it.

Why Unmarried Couples Face the Highest Stakes

The Intestate Succession Act 1967 defines a strict hierarchy of beneficiaries: spouse, children, parents, siblings, grandparents, aunts, and uncles. "Partner," "de facto spouse," "significant other," and "cohabitant" are not legal categories. They don't appear anywhere in the statute.

Here's what happens if your partner dies intestate:

Property. If the home is held in your partner's sole name, their blood relatives inherit it. You can be asked to vacate. If you hold it as tenants-in-common (each owning a share), your partner's share passes to their relatives under intestacy — not to you. Only joint tenancy (with the right of survivorship) would protect you, and that only works for property you co-own.

Bank accounts. Joint accounts are frozen upon death notification. Sole accounts go entirely to intestacy beneficiaries. Any money you've contributed to your partner's sole account is lost unless you can prove a resulting trust — an expensive legal argument.

CPF. Without a CPF nomination naming you, the funds go to the Public Trustee for distribution to intestacy beneficiaries. You receive nothing.

Insurance. Life insurance proceeds go to the named beneficiary. If your partner named a parent or sibling years ago and never updated the nomination, that's where the money goes.

In the worst case: your partner dies, you lose the home, all shared savings, the CPF balance, and the insurance payout — all in one event.

The Essential Protections for Unmarried Couples

1. Write a Will (Non-Negotiable)

A will is the only way to leave assets to an unmarried partner in Singapore. Without one, the law pretends you don't exist.

Both partners need their own wills. Each will should:

• Name the other partner as a beneficiary for specific assets or a residuary clause covering everything not otherwise specified
• Appoint the other partner as executor (so they control the estate administration process)
• Include a backup beneficiary in case the partner dies first or simultaneously

For simple wills, a lawyer charges $200-$500. Online will services cost $50-$150. The will must meet Wills Act requirements: written, signed, witnessed by two people who aren't beneficiaries.

Muslim exception. If either partner is Muslim, Faraid inheritance law limits testamentary freedom to one-third of the estate. The remaining two-thirds goes to Faraid heirs. A Muslim partner can use a wasiat (Islamic will) to leave the discretionary one-third to an unmarried partner, but cannot override the two-thirds.

2. Check Your Property Holding Type

How property is held determines whether it passes through the will or bypasses it entirely:

Joint tenancy — the surviving co-owner automatically receives the deceased's share through the right of survivorship. The will has no effect on this property. This is the strongest protection for unmarried couples.

Tenancy-in-common — each owner holds a defined share. The deceased's share passes through their will (or intestacy if no will). Your partner's relatives could inherit their share of the home you live in.

If you own property together as tenants-in-common, converting to joint tenancy is the most important step you can take. If only one partner owns the property, adding the other as a joint tenant requires careful consideration of ABSD (Additional Buyer's Stamp Duty) and other tax implications.

For HDB flats, the rules are stricter. Unmarried couples generally cannot jointly own HDB flats unless they meet specific eligibility schemes (e.g., the Joint Singles Scheme for two singles aged 35+). If only one partner owns the HDB flat, the other has no ownership rights regardless of financial contributions.

3. CPF Nomination

Both partners should nominate each other (and/or their preferred beneficiaries) on the CPF Board website. CPF nominations can name anyone — there's no requirement for the nominee to be a relative or spouse.

This is free, takes 10 minutes, and bypasses the entire intestacy system. Without it, CPF goes to the Public Trustee and is distributed to blood relatives under the Intestate Succession Act.

Remember: this nomination must be re-done if either partner ever marries, because marriage automatically revokes all CPF nominations.

4. Insurance Nominations

Review every life insurance policy and name the appropriate beneficiary. Insurance nominations override the will — they're a separate legal mechanism. If a policy still names a parent or sibling from years ago, update it.

Do not assign policies under Section 73 of the Conveyancing and Law of Property Act — this creates a statutory trust for "spouse and children," which excludes unmarried partners by definition.

5. Lasting Power of Attorney

If your partner is incapacitated by illness or injury, you have no legal authority to make decisions on their behalf unless you hold an LPA. Without one, the court must appoint a deputy — and the court may appoint a family member over you, especially if the family opposes the relationship.

Both partners should register an LPA naming each other as donee. Form 1 (standard) costs $75 for OPG registration plus $25-$80 for the certificate issuer.

6. Advance Medical Directive and ACP

If your partner is terminally ill, who speaks for them? Without an LPA covering medical decisions, the attending doctors will defer to the legal next-of-kin — which means parents or siblings, not you.

An AMD handles the specific question of whether to use extraordinary life-sustaining treatment. Advance Care Planning (ACP) covers broader treatment preferences. Both should name the trusted partner as the point of contact.

Common Mistakes Unmarried Couples Make

Assuming cohabitation creates rights. Singapore does not recognise common-law marriage or de facto relationships. Living together for 20 years creates no legal inheritance rights.

Only one partner making a will. Both need wills. If Partner A's will names Partner B but Partner B has no will, Partner A inherits nothing if Partner B dies first.

Forgetting about CPF. Even with a perfect will, CPF bypasses it entirely. CPF nomination is the only way to direct these funds.

Not checking property holding type. Many couples assume joint ownership means joint tenancy. It might be tenancy-in-common. Check with HDB or SLA.

Who This Is For

• Unmarried couples in Singapore who share a life but have no legal protections
• Same-sex couples (Singapore law does not provide spousal inheritance rights for same-sex partners, married abroad or otherwise)
• Long-term cohabitants who have commingled finances and property
• Anyone whose family may not recognise or support their partnership

Who This Is NOT For

• Married couples (existing spousal protections under the Intestate Succession Act and Women's Charter provide significant baseline coverage)
• Couples where neither partner owns significant assets

Frequently Asked Questions

Does Singapore recognise common-law marriage?

No. There is no concept of common-law marriage, de facto partnership, or domestic partnership in Singapore inheritance law. Without a will, an unmarried partner has no inheritance rights regardless of the duration or nature of the relationship.

Can my partner's family contest a will that names me?

Yes. Any interested party can file a caveat or contest a will in the Family Justice Courts. The grounds include undue influence, lack of mental capacity, and improper execution. However, a properly drafted and witnessed will that clearly states the testator's wishes is difficult to overturn. Using a lawyer for the drafting adds another layer of protection.

What if my partner is Muslim?

A Muslim testator can leave a maximum of one-third of their estate to non-Faraid heirs through a wasiat. The remaining two-thirds must follow Faraid distribution rules. This means an unmarried partner of a Muslim person can receive at most one-third of the estate, even with a will.

Can we both be on the HDB lease?

Only if you qualify under the Joint Singles Scheme (both aged 35+, both Singapore Citizens or at least one SC and one PR). Otherwise, HDB flats are restricted to specific family nuclei. If only one partner is on the lease, the other has no ownership claim.

What's the first thing we should do?

Make CPF nominations naming each other. It's free, takes 10 minutes, and protects the largest liquid asset most Singaporeans have. Then check your property holding type. Then write wills.
