Will Writing Singapore: Requirements, Costs, and What Every Will Must Include

A will is the most basic legal document in estate planning, yet a significant number of Singaporeans either do not have one or have one that is technically invalid. The cost of getting it wrong — frozen assets, family disputes, and the courts deciding who gets your property — can far outweigh whatever was saved by cutting corners.

Here is what Singapore law actually requires, what wills cost, and the errors that make them unenforceable.

Legal Requirements Under the Wills Act

A will in Singapore is governed by the Wills Act 1838 (Cap 352). For it to be valid, it must satisfy all of the following:

Age: You must be at least 21 years old to make a will, unless you are a member of the Singapore Armed Forces on active service, in which case you may make a privileged will at any age.

Mental capacity: You must be of sound mind at the time of signing — meaning you understand what a will is, what assets you own, who your natural heirs are, and what the document says. A will signed during a period of dementia, heavy sedation, or severe mental illness can be challenged in court.

Writing: The will must be in writing. It can be handwritten or typed.

Signature: You must sign at the foot or end of the will (or acknowledge an existing signature) in the presence of both witnesses simultaneously. An initial, thumbprint, or a mark is acceptable, but it must be deliberate and intended as your signature.

Two witnesses: You must have exactly two witnesses present at the same time when you sign. They must be adults of sound mind. Each witness must then sign the will in your presence (though not necessarily in each other's presence).

Beneficiaries cannot witness. If a beneficiary — or their spouse — acts as a witness, that beneficiary's gift under the will is automatically void, even if the will itself remains valid. This is one of the most common and costly mistakes in DIY wills.

What Should a Will Cover?

A properly drafted will should address:

• Executor appointment — who will carry out the instructions in the will and apply for the Grant of Probate
• Asset distribution — who receives what, with specific descriptions of major assets where helpful
• Residuary clause — a catch-all provision covering assets not specifically mentioned
• Guardian appointment — who will care for minor children if both parents die
• Funeral wishes (optional, but useful to record)
• Specific bequests — particular items to specific people (jewellery, art, sentimental items)

Note that CPF savings, HDB flat ownership in joint tenancy, and nominated insurance proceeds do not pass under a will — they operate through separate mechanisms regardless of what your will says. If your will leaves your CPF funds to your spouse but you have not made a CPF nomination, the funds go to the Public Trustee, not your spouse.

Critical Traps That Invalidate or Undermine Wills

Marriage automatically revokes a will. If you marry after making a will, the entire will is revoked, unless it was made specifically in contemplation of that marriage. Newly married people frequently discover too late that their pre-marriage will is legally void.

Divorce does not revoke a will. This is the opposite of what most people expect. After a divorce, your ex-spouse remains a beneficiary and executor if named in the will, unless you update it. The Wills Act was amended in 2022 to automatically revoke gifts to a former spouse and to remove them as executor upon divorce — but only for wills made after November 15, 2022. Older wills are unaffected.

A cohabiting partner has no automatic rights. Under the Intestate Succession Act, an unmarried partner receives nothing if you die without a will. Your entire estate passes to blood relatives. The only way to protect a long-term partner who is not legally married to you is through an explicit will.

Unattested additions are invalid. If you hand-write amendments directly on the will after signing, those additions are not valid unless the will is re-executed with witnesses. Any changes should be made through a formal codicil.

How Much Does a Will Cost in Singapore?

Free or very low cost (DIY): Numerous websites and charities offer free will templates for Singapore. These can be legally valid if executed correctly, but the risk of errors — especially with complex estates, overseas assets, or blended families — is significant.

S$200 to S$500 (will writing services): Non-lawyer will writing firms typically charge in this range for a basic will. Be aware that some use low-cost wills as entry points to sell life insurance or investment products. Your will is independent of any financial product.

S$300 to S$800 (lawyer-drafted): A solicitor-drafted will from a law firm in Singapore typically costs S$300 to S$800 for a straightforward estate. More complex wills with trusts, overseas assets, or multiple properties can cost significantly more.

S$100 to S$200 (legal aid schemes): The Law Society of Singapore and Community Legal Clinics offer subsidised will writing services for eligible applicants.

Online Wills: Are They Valid in Singapore?

A will written on a computer and printed is entirely valid — "online" simply describes how the document was created. The physical document still needs to be signed in wet ink with two witnesses present.

Fully electronic wills with digital signatures are not currently valid under the Wills Act. If a will writing platform suggests your will can be signed and witnessed entirely digitally, verify carefully that it meets the physical signing requirements under Singapore law.

Storing and Registering Your Will

The Singapore Academy of Law (SAL) operates the Wills Registry, where you can register the existence of your will (not its contents). Registration confirms that a will exists and where it is stored — useful for executors who need to locate the document after death.

Store the original will in a secure location: a bank safe deposit box, a home safe, or with your solicitor. Tell your executor where to find it.

Wills and the Broader Estate Plan

A will handles what happens to your legal estate — your bank accounts, investments, personal property, and tenancy-in-common property shares. But several major assets sit outside the will:

• CPF savings (covered by CPF nomination)
• Joint tenancy property (passes to surviving owner by right of survivorship)
• Nominated insurance policies (paid directly to nominees)

For a complete picture of how all these pieces fit together, including the interaction between your will, CPF nomination, LPA, and Advance Medical Directive, the Singapore End-of-Life Planning Guide provides a coordinated framework with checklists, decision trees, and Singapore-specific procedures.

Getting a will in place is not about being morbid. It is about ensuring the people you care about are protected, and that your wishes — not a statutory formula — determine what happens to everything you have built.
