Points to note

Please check the basics of the policy when you apply.

  • When applying for the policy, please confirm the product name, policy period, premium-payment period and the insured , and be sure to receive and check the policy wording.
  • Before concluding the contract, please read the product description and policy wording.
  • If you cancel an existing policy to take out a new one, acceptance may be declined, the premium may rise and the cover may differ — please take note.
  • Payment of the claim may be restricted by exclusions and payment-limitation grounds.

Nullity of the contract

If the insured event has already occurred at the time the contract is made, the contract is void. However, where the contract is void due to the company's intent or negligence, or where the company knew or could have known of the nullity before acceptance yet did not refund the premium, the company refunds the premium with interest at the policy-loan rate published by the Korea Insurance Development Institute, compounded annually, for the period from the day after payment to the day of refund.

Losses not covered

The specific losses not covered (exclusions) are set out in each insurer's policy wording and product description; on this page, see the “Cover” tab(or the “Losses not covered” section) for the main exclusions. For other cover-specific grounds on which claims are not paid, please refer to the policy wording.

Cover start date

The company provides cover, in accordance with the policy, from the time it accepts the application and receives the first premium. Where the company accepts the application after receiving the first premium with it, cover also begins from the time the first premium was received.

Policyholder's handwritten signature

The application must be completed by the policyholder, and the policyholder and the insured must sign it by hand. Failure to sign by hand may result in disadvantages regarding the validity of the contract. On an internet cyber-mall, an electronic signature may be used instead.

Right to be informed and have the product explained

The policyholder has the right to be given and have explained the information needed about the product they wish to buy.

Duty to explain

The insurer and N2N Insurance Brokerage must explain the important matters of the product to ordinary financial consumers.

Duty of disclosure before the contract

When applying, the policyholder, the insured or their agent must disclose truthfully the facts they know regarding the questions in the application (including the questionnaire). Otherwise the claim may be declined or the contract cancelled. Where insurance is taken out by telephone or other means of communication, the duty is performed by answering the seller's questions, which are recorded, without a separate written questionnaire, so answers must be given with particular care.

Duty of disclosure after the contract

If, after the contract is made, any of the following arises in respect of the subject-matter insured, the policyholder or the insured must notify the company in writing without delay and obtain endorsement on the policy.

  • When intending to take out, or learning of, a contract with another insurer covering the same risk as this contract
  • When transferring the subject-matter insured
  • When altering, rebuilding or extending the subject-matter insured or the building housing it
  • When moving the subject-matter insured to another location
  • When the risk is, or is found to have been, materially changed

Withdrawal of the application

  • The policyholder may withdraw the application within 15 daysof receiving the policy, in which case the premium paid is refunded. However, a contract more than 30 days after application (45 days where a policyholder aged 65+ contracted by telephone) cannot be withdrawn.
  • In addition, a medical-examination contract, a contract with a cover period of 90 days or less, guarantee insurance, statutory compulsory insurance, liability insurance under the Automobile Accident Compensation Act, or a commercial-insurance contract concluded by a professional financial consumer cannot be withdrawn.

Quality-assurance scheme

  • If, after application, the policyholder did not receive the policy wording and their copy of the application, was not given an explanation of the important contents of the wording, or did not sign the application by hand, they may cancel the contract within 3 monthsof the contract being formed.
  • In that case the premium already paid is refunded to the policyholder, with interest at the policy-loan rate compounded annually for the period the premium was held.

Why the surrender value may be less than the premiums paid, or nil

The surrender value is the amount paid if the contract is cancelled early. Unlike bank savings, insurance combines risk protection and savings: part of the premium is paid out as claims to other policyholders who suffer accidents, and part covers the insurer's operating expenses, so the surrender value on early cancellation may be less than the premiums paid, or nil.

Depositor protection

  • This policy is protected under the Depositor Protection Act, such that the surrender value (or the maturity benefit) plus other payments is protected up to “KRW 100 million per person” (aggregated with the insurer's other protected products).
  • Separately, the aggregate accident-claim amount of that insurer's protected products is “KRW 100 million per person” protected.
  • (However, a policy whose policyholder and premium payer is a corporation is not protected.)

Tax benefit (protection-type insurance)

Under Article 59-4(1) of the Income Tax Act (special tax credit), for protection-type insurance taken out by an employee only, a tax credit of 12% of the premium paid (capped at KRW 1 million per year) is available. Tax matters may change with amendment or repeal of the relevant tax law.

Personal-data protection

Except as provided by law, the insurer and N2N Insurance Brokerage do not collect, use, inspect or provide personal data related to this contract — for its conclusion, maintenance and claim payment — without the consent of the policyholder, the insured or the beneficiary. However, for those purposes the insurer may, with the consent of the policyholder and the insured and in accordance with law, provide personal data to other insurers and insurance-related bodies.

When you need professional indemnity (E&O) insurance

Risk patterns common in professional advisory work — a 5-scenario self-check

💼

Any advisory business providing professional services or advice

Advisory work — legal, accounting, design, IT, consulting, advertising — can cause a client financial loss through negligence, error or omission in carrying it out.

📜

Licensed professionals required by law to hold liability insurance

Some professionals — insurance brokers, licensed real-estate agents, certified public accountants — are required by law to hold professional indemnity insurance.

🖥️

Where intangible deliverables are supplied — IT development, SI, consulting

Defects in, or delays to, system-development and consulting deliverables can cause loss to the client and give rise to claims.

📂

Where past work carries latent risk

Claims on professional work are sometimes brought long afterwards. Managing latent risk from past work calls for a well-set Retroactive Date.

🔁

When changing field or renewing/switching insurers

Claims-Made cover is prone to gaps, so on renewal or switching, check the continuity of the Retroactive Date and the Extended Reporting Period (ERP).

A dispute pattern seen in the field

The two most important dates in professional indemnity (E&O) are the ‘Retroactive Date’ and the ‘Reporting Period’. Because it is written on a Claims-Made basis, it covers a claim made during the policy period only if the work giving rise to it was performed after the Retroactive Date. If, when switching or renewing, the Retroactive Date moves forward, claims from work done in the interim can fall into a cover gap. Claims relating to past work can also arrive after the policy ends, so designing the Extended Reporting Period (ERP) matters. With E&O the key is not ‘that you bought it’ but ‘from when the work is covered and until when it can be reported’.

3 things easily missed when buying professional indemnity (E&O)

The wording and structure items decision-makers most often overlook

  • 1

    Miss the Retroactive Date and past work falls into a gap

    Claims-Made cover only covers work done after the Retroactive Date. If that date moves forward when switching insurers, claims from interim work drop out of cover.

  • 2

    Claims after the policy ends — Extended Reporting Period (ERP)

    Claims relating to past work can arrive after the policy ends. An ERP endorsement should be designed so such claims can be reported for a set period after termination.

  • 3

    Whether the profession-specific wording actually covers your work

    Risks and dedicated wordings differ by profession — legal, accounting, design, IT. Check that the policy's definition of covered work captures the work you actually perform.

Frequently asked questions

The questions asked most when considering professional indemnity (E&O)

What is professional indemnity (E&O) insurance?

It is liability insurance covering the financial loss caused to a client, and the defense costs, when a professional providing services or advice is negligent or makes an error or omission. It applies across advisory work — lawyers, accountants, architects, engineers, IT consultants, advertising agencies, insurance brokers and others.

Is it compulsory for some professionals?

Some professionals — insurance brokers, licensed real-estate agents, certified public accountants — are required by law to hold professional indemnity insurance. The standard differs by licence and field, so confirm it against the relevant law.

What is the Retroactive Date?

In a Claims-Made policy it is the start date from which covered work runs. Claims arising from work done after the Retroactive Date are covered, so when switching insurers, ensure the date does not move forward.

Why is an Extended Reporting Period (ERP) needed?

Claims-Made cover responds to claims made during the policy period. Because claims on past work can arrive after termination, an ERP endorsement is designed so such claims can be reported for a set period afterwards.

Are willful or fraudulent acts covered?

No. Loss from willful acts, crime or fraud is excluded. E&O covers professional liability arising from ‘negligence, error or omission’.

How is the premium calculated?

The insurer calculates it based on profession and work risk, revenue, the limit, the Retroactive Date and Reporting Period design, and past claims history. The exact premium and terms are confirmed after underwriting by insurers such as AIG, Chubb, DB, Hyundai, KB and Meritz.
