This bill for. declaratory and other relief was heard on stipulated facts and documentary evidence which the judge treated as a statement of agreed facts. The plaintiff seeks to have the defendant Graye ordered to execute an assignment to it of bis rights and causes of action to the extent of $12,000 against any third party responsible for the sinking of his yacht.
On August 28, 1966, Graye’s yacht, the “Nepenthe,” was sunk off Tinker’s Ledge, Marblehead, and has never been recovered. The yacht was insured by Graye with the plaintiff under a policy with a limit of $12,000. The full amount of the policy was paid by the plaintiff to Graye on October 25, 1966. Thereafter, Graye brought an action of tort in the Superior Court against the defendant Williams who is the owner of the boat that collided with the “Nepenthe.” In the present proceeding, the plaintiff seeks to be subrogated to the rights of Graye in his action against Williams to the extent of the $12,000 payment it has made to Graye.
The policy contained no express provision with respect to subrogation. The plaintiff made an attempt to salvage the yacht, but without success. Thereafter, on November 25,1966, the plaintiff presented Graye with a subrogation agreement which Graye refused to execute. The plaintiff took the position that subrogation is not dependent on its being expressly provided for in the policy but rather is based on principles of equity and the nature of the contract of insurance. Graye contended that no right of subrogation exists because it is not expressly provided for in the policy; he further contended that when the plaintiff exercised its salvage rights it made an election and is now estopped to claim subrogation.
The judge ordered a decree to be entered adjudging that the plaintiff was entitled to be subrogated to the rights of Graye against Williams to the extent of $12,000, and order *240 ing Graye to execute and deliver to the plaintiff an assignment of his rights and causes of action against Williams to the extent of $12,000. From a decree in accordance with this order, Graye appealed. Graye demurred to the bill, and from an interlocutory decree overruling the demurrer he also appealed.
1. The bill was not demurrable; it presents a justiciable issue and an actual controversy. This remains true even though the respective rights and responsibilities of the parties are contingent upon the outcome of the tort action against the defendant Williams by Graye. General Laws c. 231A is “to be liberally construed and administered,” and where, as here, an actual controversy has arisen, a bill for declaratory relief will lie though the liability of the defendant Williams has not been established.

2. The right of subrogation is not dependent on contract but “rest[s] upon natural justice and equity.”

v.
Lowell,
Arnould continues:
“ ‘As
between the underwriter and the assured, the underwriter is entitled to the advantage of every right of the assured, whether such right consists in contract, fulfilled or unfulfilled, or in remedy for tort capable of being insisted on or already insisted on, or in any other right ... by the exercise or acquiring of which right or condition the loss against which the assured is insured, can be, or has been diminished.’ ”

The foregoing-views are supported by other commentators on the subject. See Kimball and Davis, The Extension of Insurance Subro-gation, 60 Mich. L. Rev. 841, 849; Appleman, Insurance Law and Practice (1962) §4121; and Couch, Insurance (2d ed.) § 61: 332. The case law is to the same effect. See, e.g.,
The “Potomac,”
3. Graye suggests that the medical release form presented to him by the plaintiff (and signed by him) constitutes a waiver of subrogation rights because of a clause contained therein that expressly reserves subrogation rights for automobile cases. He argues that by reserving such rights for automobile cases, the company waives them for all other cases (including, of course, marine cases). This argument must be rejected since the release form pertains to personal injuries only and not to property damage. 4

4. Graye’s final argument, unsupported by authority, that the plaintiff's attempt to salvage the yacht amounted to an election which precludes subrogation is without merit. We are of opinion that the attempted salvage of the yacht by the plaintiff was not inconsistent with subrogation, and therefore did not estop the plaintiff from pursuing that remedy. See

Castellain v. Preston, [1883] 11 Q. B. 380, 388.
Contrary to Graye’s contention, we are not persuaded that because the Legislature has expressly provided for subrogation in fire insurance policies (G. L. c. 175, § 99) it intended to abrogate subrogation in other types of policies.
