Travel insurance used by traveler abroad is the insurance which covers the damage on the bodily injury by rapid, unintended and external accident. Recently traveler overseas tend to enjoy marine sports and other sports like golf, ski staying at one place. Travel insurance can provide them the coverage for medical and health expenses and more if they are injured by the sports accident of overseas travel. The traveler abroad can claim the damage based on the contract and tort to the liable third party when they are injured by the sports accident of overseas travel. Also, they insured can claim the compensation for losses to the insurance company in the event of an occurrence of sports accident of overseas travel. But here, one issue arises whether the traveler can be compensated doubly by the liability of the third party and the insurance. As a result the issue of offsetting profit and loss arises because the double compensation is prohibited by the concept of justice and equity of law. Offsetting profit and loss is deeply concerned with the subrogation of insurance. If the subrogation of insurance is allowed, the insurance money received is to be deducted from the compensation of liability of the third party as the insurer paying the loss is entitled to take on all right and remedies belonging to the insured against a third party with respect to any injury or breaches covered by the policy. Subrogation of insurance differs according to the classes of insurance at the Korean Commercial Act. Article 682 of the Korean Commercial Act, which defines accident insurance on the property damage allows the subrogation of insurance. Article 729 of the Korean Commercial Act, which defines life insurance does not allow the subrogation of insurance. But Article 729 of the Korean Commercial Act, which defines personal accident insurance allows exceptionally the subrogation of insurance under the provisory clause. Travel insurance is understood as the personal accident insurance by the interpreting insurance policy and the position of the Supreme Court Decision. Therefore subrogation of insurance at the travel insurance is allowed exceptionally under the provisory clause of Article 682 of the Korean Commercial Act and the travel insurance money received is to be deducted from the compensation of liability of the third party. This is supported by Supreme Court Decision; Nov 24, 1998, 98 Da 25061.
