Bearing in mind that the claim check voucher and the Release of Claim and Subrogation Receipt presented by Malayan Insurance are already part of the evidence on record, and since it is not disputed that the insurance company, indeed, paid PhP 700,000 to the assured, then there is a valid subrogation in the case at bar. As explained in Keppel Cebu Shipyard, Inc. v. Pioneer Insurance and Surety Corporation:
Subrogation is the substitution of one person by another with reference to a lawful claim or right, so that he who is substituted succeeds to the rights of the other in relation to a debt or claim, including its remedies or securities. The principle covers a situation wherein an insurer has paid a loss under an insurance policy is entitled to all the rights and remedies belonging to the insured against a third party with respect to any loss covered by the policy. It contemplates full substitution such that it places the party subrogated in the shoes of the creditor, and he may use all means that the creditor could employ to enforce payment.
We have held that payment by the insurer to the insured operates as an equitable assignment to the insurer of all the remedies that the insured may have against the third party whose negligence or wrongful act caused the loss. The right of subrogation is not dependent upon, nor does it grow out of, any privity of contract. It accrues simply upon payment by the insurance company of the insurance claim. The doctrine of subrogation has its roots in equity. It is designed to promote and to accomplish justice; and is the mode that equity adopts to compel the ultimate payment of a debt by one who, in justice, equity, and good conscience, ought to pay.[33]
Considering the above ruling, it is only but proper that Malayan Insurance be subrogated to the rights of the assured.
