OPINION
COLLINS, Justice.
This is an appeal from a district court judgment enforcing an arbitration award in a dispute between two automobile insurance companies and the heirs and estate of the deceased insured.
Respondents cross-appeal the district court's assumption of jurisdiction over the dispute.
Michael Kent Clark was killed in an accident while a passenger in a nonowned vehicle driven by an uninsured host. Clark was insured in two separate unrelated policies issued by appellant insurance companies which provided uninsured motorist coverage with limits for each policy of $10,000 for each person and $20,000 for each accident. He paid the full premium for the coverage under each policy.
This action was brought by and on behalf of the surviving heirs of the deceased and sought damages accruing to them by reason of his death. Each policy contained an "other insurance" provision. The following paragraph, identical in wording, appeared in that section of each policy:
"[I]f the insured has other similar insurance available to him and applicable to the accident, the damages shall be deemed not to exceed the higher of the applicable limits of liability of this insurance and such other insurance, and the company shall not be liable for a greater proportion of any loss to which this coverage applies than the limit of liability hereunder bears to the sum of the applicable limits of liability of this insurance and such other insurance."
Each policy also contained an identical arbitration clause which reads:
"If any person making claim hereunder and the Company do not agree that such person is legally entitled to recover damages from the owner or operator of an uninsured automobile because of bodily injury to the Insured, or do not agree as to the amount of payment which may be owing under this Part, then, upon written demand of either, the matter or matters upon which such person and the Company do not agree shall be settled by arbitration in accordance with the rules of the American Arbitration Association, and judgment upon the award rendered by the arbitrators may be entered in any court having jurisdiction thereof. Such person and the Company each agree to consider itself bound and to be bound by any award made by the arbitrators pursuant to this part."
A controversy arose between the claimants under the policies and the insurance companies and between the insurers themselves. The controversy was referred to an arbitrator who, after lengthy hearings, awarded Clark's heirs and estate $17,000. The arbitrator also found that an uninsured motorist, through gross negligence, proximately caused the death of Michael Kent Clark, a guest. He prorated the award equally between the two insurers, less any medical expenses paid by the companies.
The parties to the arbitration entered into a stipulation before the arbitrator which set forth, along with certain agreements, the following issues:
1. That the guest statute was in issue on the question of liability.
2. The amount of the damages.

*41 3. Which, if either, policy applied, and if so the liability of the insurers under those policies.
4. Whether the driver was an uninsured motorist.
5. That there was no waiver of the rights of any of the parties to pursue by any legal means the jurisdiction of the arbitrator over any of the foregoing issues.
Following entry of the arbitration award, respondents petitioned the district court for confirmation of the award.[1] Appellants objected to the petition and asked the lower court to vacate, modify or correct the award on the principal ground that the award was in excess of the policy limits or coverage, and thus the arbitrator exceeded his jurisdiction by proration of the $17,000 damage award equally between the two insurers. Respondents countered that position by contending the court had no authority to review the award of the arbitrator and had jurisdiction only to confirm the award as made by the arbitrator.
The lower court ruled it did have jurisdiction to hear and determine the issues raised by appellants' objections, but that the objections were without merit, and thereupon approved the arbitrator's award in total.
From that order both sides appeal; appellant from the order approving the arbitration awards; respondents from the determination of the lower court that it had jurisdiction to consider the objections.
The issues before us for decision are:
1. Did the arbitrator exceed his powers in determining the controversy submitted to him?
2. Did the trial court properly exercise its power to review and enforce the arbitration award?
Other issues are obviously present in this case such as:
1. Did the arbitrator and lower court properly interpret the policy clauses involved here?
2. What is meant by similar insurance under the uninsured motorist provision of the policy and should any loss be prorated in proportion to the higher limit of liability under that policy and other similar insurance?
However, we do not reach the latter issues in this opinion because we conclude that the first two issues are decisive of the matter, and affirm the judgment below.
1. The question of coverage under the policies was submitted to the arbitrator by the parties, and he had not only the right but the power or jurisdiction to decide that issue of law. We think that the stipulation of the parties relating to the issues submitted to the arbitrator, No. 3 above, expressly related to the question of coverage. The arbitrator having decided the issue against appellants, they are bound by that decision unless under the same stipulation where they reserved the right to pursue legal review of the jurisdiction of the arbitrator, he exceeded his jurisdiction, or unless the arbitrator exceeded his power under Nevada statutes regulating arbitrations. An arbitrator may decide all issues voluntarily submitted to him. The range of his decision is bound only by the scope of the submission. 5 Cal.Jur.2d Arbitration and Award secs. 44-45 (1967); D. Blashfield, Automobile Law and Practice sec. 332.6 (3d ed. 1966); G. Couch, Cyclopedia of Insurance Law sec. 50:224-26, 228-30 (2d ed. 1965). N.R.S. 38.030; Forrest v. Hotel Conquistador, 193 Cal. App.2d 503, 14 Cal. Rptr. 349 (1961); Pacific Fire Rating Bureau v. Bookbinders' and Bindery Women's Union No. 31-125, 115 Cal. App.2d *42 111, 251 P.2d 694 (1952); Bierlein v. Johnson, 73 Cal. App.2d 728, 166 P.2d 644 (1946); Hetherington v. Continental Ins. Co. of New York, 311 Ill. App. 577, 37 N.E.2d 366 (1941); Schreck v. Standard Acc. Ins. Co., 102 Pa.Super. 18, 156 A. 565 (1931).
The arbitration agreements in both policies, quoted above, are identical and clearly broad enough to encompass both questions of fact and law. Both types of questions or issues were submitted to the arbitrator as shown by the stipulation of the parties.
It is true under the Nevada statute[2] the arbitrator or any party could have submitted any question of law to the court for an opinion and would have been bound by such opinion. But not having done so, they are deemed to have consented to the arbitrator's decision on that issue of law and may not thereafter attack his decision even if erroneous. Fisher v. State Farm Mutual Auto. Ins. Co., 243 Cal. App.2d 749, 52 Cal. Rptr. 721 (1966); Jordan v. Pacific Auto. Ins. Co., 232 Cal. App.2d 127, 42 Cal. Rptr. 556 (1965); Interinsurance Exchange of Auto. Club of So. Cal. v. Bailes, 219 Cal. App.2d 830, 33 Cal. Rptr. 333 (1963); Morceau v. Gould-Nat'l Batteries, Inc., 344 Mass. 120, 181 N.E.2d 664 (1962); Wilcox v. Utica Mutual Ins. Co., 236 N.Y.S.2d 119 (1962). Cf. Agricultural Ins. Co. of Watertown, New York v. Biltz, 57 Nev. 370, 381, 64 P.2d 1042 (1937).
2. The trial court could entertain appellants' motion to vacate, modify or correct the award, but because of the breadth of the submission as disclosed in the preceding section of this opinion, its jurisdiction was limited to the provisions of N.R.S. 38.170[3] and 38.180[4].
Obviously, the lower court failed to find any grounds for vacation or modification of the award under either N.R.S. 38.170 or *43 38.180. Likewise, the lower court found, in approving the award, the question of coverage under the policies was submitted to the arbitrator and decided by him. We agree with both conclusions.
The judgment is affirmed.
