Underwriting for term life: medical underwriting, financial underwriting, smoker definitions and loading, exclusion, postponement and decline

Definition: what underwriting is

Underwriting (核保) is the process by which an insurer assesses the life and health risk of covering a person and, on that basis, sets the premium and the terms of cover (LIA, Apr 2024). The basic mechanism of insurance is the risk pool: the premiums of all policyholders go into a common fund used to share risk fairly; for the fund to be sustainable, the premium each person pays must be commensurate with their risk. In general, the older a person is, the more likely they are to fall ill, become disabled or die early, so younger people usually pay lower premiums; where there is a medical history, an application may be loaded or even declined (LIA, Apr 2024).

The LIA guide lists the guiding principles insurers follow in underwriting: to act fairly and reasonably; to assess each case on its own merits and individual risk profile; to assess objectively and holistically on the basis of disclosures and medical evidence; to apply the same set of principles to all conditions and risk profiles; and to charge a premium commensurate with the risk. The guide also states, however, that each insurer has its own underwriting guidelines and risk appetite, so underwriting outcomes may differ. For term life, underwriting determines which risk class you fall into and therefore the premium; see What determines the premium.

What underwriters look at

The table below is compiled from the factors listed in the LIA guide. Insurers obtain this information through the proposal form, questionnaires, medical examinations and doctors' reports.

LIA's case studies show how these factors translate into outcomes. For example, a 34-year-old commercial diver, whose occupation carries a higher risk of disability, may be declined for TPD, and critical illness and hospitalisation cover may carry exclusions (LIA, Apr 2024, case 10). These cases are illustrative and are not any insurer's actual decision.

The underwriting process, medical examinations and costs

Underwriting starts with the proposal form. The proposal form is the insurer's main source of underwriting information, and the insurer adds questionnaires as needed, for example an asthma questionnaire for someone who has disclosed asthma or a diving questionnaire for someone who dives. The process in the LIA guide is: on receiving the proposal form, the insurer decides whether the information is sufficient to classify the risk; if not, it asks for more; then it makes the underwriting decision (LIA, Apr 2024, section 3.2).

• Medical examination and doctors' reports: depending on age and sum assured, the applicant may need a medical examination or tests at the insurer's panel doctor; where there is ongoing follow-up or a co-existing condition, the underwriter may request a report from the treating doctor.
• Costs: reports for hospitalisation insurance are paid for by the applicant; for other cover, the costs of medical examinations, tests and medical reports may be borne by the insurer, but if the application is accepted on standard terms and the applicant does not take it up, the applicant may have to pay, whereas if a counter-offer with loading or exclusion is made and the applicant declines it, the insurer bears the cost (LIA, Apr 2024, section 3.2.1).
• Each benefit assessed separately: the same application may receive different outcomes on different benefits; for example, someone with a history of a slipped disc may get death cover on standard terms while TPD and hospitalisation cover carry a spinal exclusion (LIA, Apr 2024, section 3.2.2).
• Time: usually days to weeks, as determined by the insurer; where a report has to be obtained from a doctor, the purchase process may exceed 90 days (LIA, Dec 2021, section 3.2). Interim accidental death cover before inception and the free-look period are in How to apply.

The four underwriting outcomes

For a policy accepted with loading or exclusion, fresh medical evidence may be submitted to the insurer for a reassessment of the risk profile once the condition improves; the outcome is for the insurer to decide (LIA, Apr 2024). LIA's illustrative cases also show that one application can have different outcomes across benefits: a type 2 diabetic with poor glycaemic control may be loaded for death cover and declined for TPD, critical illness and hospitalisation; a lung cancer survivor who has stopped smoking may be accepted with loading for death and TPD while critical illness and hospitalisation cover remain declined. LIA states expressly that the cases do not cover every outcome at every insurer, and past outcomes do not guarantee the same conclusion in similar cases.

Disclosure and the contestability period

The principle of utmost good faith (最大诚信原则) requires both parties to the contract to provide accurate information honestly. The LIA guide notes that any false, inaccurate or incomplete information or statement may void the insurance contract or lead to a claim being rejected, for example failing to disclose an existing or past condition such as cancer or diabetes; the duty of disclosure rests mainly on the applicant, and where unsure whether to disclose, LIA encourages disclosure (LIA, Apr 2024, section 2.1). MoneySense likewise warns that the policy may be declared void if information is wrong or missing (updated 28 Sep 2026); the LIA glossary adds that any change in health or in the application information before the insurer accepts the application should also be notified immediately.

• Contestability period: once the policy has been in force for a certain period (usually 1 to 2 years), the insurer cannot treat the policy as never having been issued; but if fraud can be proved, the insurer may still contest the policy without time limit (LIA, May 2020).
• Position at claim: the LIA industry code states that, unless the applicant failed to provide a material fact that was asked for in the proposal form, that would have affected the insurer's decision, that the applicant knew and that the insurer could reasonably expect to be disclosed, the insurer will not reject the claim or treat the policy as never having been issued; where fraud, deception or deliberately false information is involved, the insurer will reject the claim (LIA, Dec 2021, section 5.2).
• Misstatement of age: if age was understated, the payout is adjusted to what the premiums paid would have bought at the true age; if overstated, the excess premium is refunded (without interest); if the person would not have been eligible at the true age, the insurer is entitled to treat the policy as never having been issued and refund the premiums (LIA, Dec 2021, sections 4.2 and 4.3). The suicide clause and other terms affecting payout are in Payout and nomination of beneficiaries.
• Keeping records: the applicant may ask the insurer for a copy of the completed proposal form (LIA, Dec 2021, section 3.3).

Smoker declarations, financial underwriting and foreign applicants

Smoker status. The LIA guide's cases note whether the applicant smokes, showing that smoking status is part of the risk profile, but the guide gives no uniform industry-wide definition. Insurers' public underwriting forms usually offer only a "smoker/non-smoker" tick box (for example one insurer's preliminary underwriting form, Feb 2025 version); the look-back period, whether e-cigarettes count, whether status is verified by testing, and how long after quitting an applicant may be assessed as a non-smoker are all governed by that insurer's current underwriting rules; the same principle of utmost good faith applies to the smoking declaration.

Financial underwriting. The LIA medical underwriting guide does not cover financial underwriting. In practice, where the sum assured is high or the purpose of the application needs explaining, the insurer checks that the sum assured is in proportion to income, assets, liabilities and existing cover, to prevent over-insurance. The fields in the table below are taken from two insurers' public personal insurance financial questionnaire (Feb 2026 version) and preliminary underwriting form (Feb 2025 version; names in the sources list on this page); they show only what practice focuses on and do not represent all insurers' requirements or any trigger threshold.

Documents and thresholds differ by insurer, and this site does not list monetary thresholds. Policies held by a business may also involve business operating information; see Term life for business owners.

Foreigners and non-residents. Country of residence is one of the underwriting factors LIA lists. Whether foreigners can apply and what residence or stay conditions must be met are governed by the insurer's current underwriting rules. For example, one insurer's product page states that foreigners may apply through its financial representatives (information as at 17 Aug 2026), but that is information about a single product only.

What to do if you are unhappy with the outcome

1. Review the underwriting terms: confirm whether the loading or exclusion applies only to specific benefits.
2. Submit fresh evidence: once the condition improves, fresh medical evidence can be submitted for reassessment; a declined applicant may reapply once the situation improves.
3. Compare insurers: underwriting guidelines and risk appetite differ, so outcomes may differ; disclose previous applications truthfully when comparing.
4. Complain to the insurer: the insurer will acknowledge the complaint within two working days; if no final reply is given within 15 working days, it will provide an interim reply; a final reply is given within 30 working days; if you are dissatisfied with the outcome, you may appeal in writing and the insurer will reply within 14 working days (LIA, Apr 2024).
5. FIDReC: if you are dissatisfied with the insurer's final reply, you may apply to the Financial Industry Disputes Resolution Centre (FIDReC) for mediation or adjudication; filing a dispute is free and the adjudication limit is S$150,000 per claim (FIDReC website); time limits, effective dates and binding effect are in Payout and nomination of beneficiaries.
