Estate Planning Singapore: The 5 Documents Every Adult Needs

Most Singaporeans assume their CPF savings will go to their spouse, their HDB flat will pass smoothly to their children, and their family will know what to do if they lose mental capacity. Most of those assumptions are wrong — and the consequences range from frozen bank accounts to siblings suing each other in the Family Justice Courts. High Court cost orders in inheritance disputes have reached S$149,000 in legal fees alone.

Estate planning is not about preparing for death. It is about preventing your family from having the worst administrative experience of their lives during the most emotionally devastating week they will ever face.

The 5 Documents That Actually Matter

Singapore's estate framework is uniquely fragmented. No single document covers everything. Your will does not touch your CPF. Your CPF nomination does not cover your investments. Your LPA has nothing to do with your funeral wishes. You need five distinct documents working in parallel to avoid gaps.

1. A Valid Will

Your will governs the distribution of your legal estate — bank accounts, investments, property held as tenancy-in-common, vehicles, and personal possessions. Under the Wills Act, you must be at least 21, sign it in wet ink, and have two witnesses who are not beneficiaries. If a beneficiary witnesses your will, their inheritance is automatically invalidated.

Marriage automatically revokes your will unless it was made in specific contemplation of that marriage. Divorce, however, does not revoke it — meaning your ex-spouse could remain your named executor or beneficiary if you forget to update.

2. CPF Nomination

Your CPF savings — Ordinary, Special, MediSave, and Retirement accounts — sit outside your legal estate entirely. They cannot be distributed through a will or touched during probate. Without a valid CPF nomination, your savings go to the Public Trustee, who charges tiered fees starting at 6.5% and takes up to six months to distribute them.

Making a CPF nomination is free and takes about 10 minutes on the my cpf online portal. Marriage automatically revokes any existing nomination, which catches many newly married couples off guard.

3. Lasting Power of Attorney (LPA)

An LPA allows someone you trust to make decisions about your finances, property, and personal welfare if you lose mental capacity — whether through dementia, stroke, or a serious accident. Without one, your family must apply to the court for a deputyship order, which is significantly more expensive and time-consuming.

The LPA requires certification by an accredited issuer: a doctor (median fee around S$47.50), a lawyer, or a psychiatrist (up to S$350). You must complete this while you still have mental capacity — once capacity is lost, it is too late.

4. Advance Medical Directive (AMD)

An AMD is a legal document that instructs medical professionals not to use extraordinary life-sustaining treatment if you are terminally ill and unconscious. It requires two witnesses, one of whom must be a medical doctor.

This is separate from organ donation. Under HOTA (the Human Organ Transplant Act), Singapore Citizens and PRs aged 21 and above are automatically included for kidney, heart, liver, and cornea donation unless they opt out. MTERA covers broader donations but requires explicit opt-in.

5. Insurance and Dependants' Protection Scheme

Life insurance policies and the CPF Dependants' Protection Scheme (DPS) managed by Great Eastern Life do not fall under CPF nominations. They require separate beneficiary designations and direct claims from the next-of-kin to the insurer. Many families miss these payouts entirely because they assume the CPF nomination covers everything.

The HDB Flat: Singapore's Biggest Inheritance Trap

For most families, the HDB flat represents the bulk of household wealth. How it passes depends entirely on one legal distinction made at the time of purchase: Joint Tenancy versus Tenancy-in-Common.

Joint Tenancy triggers the Right of Survivorship. When one owner dies, their share automatically passes to the surviving co-owner — bypassing the will and probate entirely. The survivor lodges a Notice of Death with the Singapore Land Authority (S$68.30 fee) and becomes sole owner.

Tenancy-in-Common means each owner holds a distinct fractional share. When one owner dies, their share enters the legal estate and must go through probate. This is where problems escalate quickly. If a husband dies intestate holding 50% as tenancy-in-common, his share gets divided under the Intestate Succession Act — potentially bringing adult children onto the title. If those children own private property, they fail HDB eligibility, and the surviving widow may be forced to sell the family home.

Inheriting an HDB flat does not guarantee you can keep it. Beneficiaries must meet strict HDB eligibility criteria — citizenship, age (often 35 for singles), and family nucleus requirements. If a beneficiary already owns private property, they have exactly six months to sell either the inherited flat or their existing property.

Why the Sandwich Generation Cannot Afford to Wait

If you are between 35 and 60, managing aging parents and young children simultaneously, estate planning is not optional. It is the single most impactful financial decision you can make for your family.

Consider this scenario: your elderly parent loses mental capacity without an LPA. You discover their CPF nomination was revoked when they remarried. Their HDB flat is held as tenancy-in-common with a step-parent you barely know. There is no will. You are now looking at a deputyship application for the incapacity, Letters of Administration for the estate (since there is no will), a potential Syariah Court Inheritance Certificate if they are Muslim, and an HDB eligibility dispute — all while grieving and paying legal fees that could easily exceed S$10,000.

The Singapore End-of-Life Planning Guide consolidates every document, deadline, and decision into a single step-by-step framework designed specifically for Singapore's legal system — covering CPF, HDB, the Family Justice Courts, and the Syariah Court in one place.

Where to Start

Begin with the two actions that cost nothing and take less than 15 minutes combined:

1. Make your CPF nomination on the my cpf online portal. Check whether marriage has revoked a previous nomination.
2. Check your HDB tenure type — log into My HDBPage to confirm whether your flat is held as Joint Tenancy or Tenancy-in-Common.

From there, prioritise getting a will drafted (basic will writing services in Singapore start around S$200-$300), and complete your LPA while you have mental capacity. The cost of doing these things now is a fraction of what your family will spend in legal fees and administrative delays if you do not.
