On May 29, 1973, Safeco moved that the city circuit court case be dismissed for lack of jurisdiction and venue. This motion was premised on allegations that Safeco had no office in the city and that St. Louis County was the proper venue and jurisdiction for the case. This motion was overruled on June 18, 1973.
On June 28, 1973, Safeco filed its answer to Oates’s petition in St. Louis City Circuit Court in which Safeco admitted that Oates was an insured under a policy issued by it which included uninsured motorist coverage and that the policy was in effect on the day of the collision with Coad. No special defenses were raised.
Coad’s counterclaim in the Iron County suit then proceeded to a judgment in Coad’s favor for $1500 in April 1974. Upon that judgment becoming final, Safeco, on August 14, 1974, filed an amended answer in the St. Louis City suit setting forth the additional defenses of res judicata and es-toppel by judgment against Oates, referring to Rule 55.32(a) and attaching a certified copy of the pleadings, instructions, and judgment from the Iron County suit. On joint motion for change of venue, the suit was transferred to the Circuit Court of St. Louis County in June of 1975.
On September 20, 1976, Oates struck all allegations of primary negligence from his petition and left remaining only the humanitarian negligence allegations against Safe-co. Safeco reargued its motion to dismiss and the court sustained Safeco’s position on the grounds that Oates was collaterally es-topped by the Iron County judgment from proceeding in the case.
Appellant Oates contends that the trial court erred in dismissing his petition, whether it did so on the grounds of collateral estoppel, res judicata, or compulsory counterclaim. Respondent Safeco replies (1) that because appellant dismissed his suit against Coad, the uninsured motorist, initially instituted by him in Iron County, and permitted the negligence issues to be decided in Coad’s favor on Coad’s counterclaim in the tort action, the appellant is barred from pursuing his rights under the uninsured motorist coverage afforded by Safeco’s policy by reason of Rule 55.32(a), the compulsory counterclaim rule; (2) that appellant’s claim is barred by the doctrine of collateral estoppel because the liability of the uninsured motorist has already been decided adversely to him in the tort action and he may not relitigate that issue again in this proceeding; (3) that appellant’s claim is barred by the doctrine of res judicata; and (4) that since appellant may not recover against Coad, the uninsured motorist, he may not recover under the terms of the policy of insurance issued to him by respondent Safeco.

Safeco contends, inter alia, the appellant was not “legally entitled to recover” damages against Coad after the termination of the Iron County case and is, therefore, precluded from proceeding against Safeco. One of the terms of uninsured motorist coverage is that the insured be legally entitled to recover against the tortfeasor.
To recover under an uninsured motorist policy, the insured does not need an unsatisfied judgment against the uninsured motorist, Noland v. Farmers Insurance Exchange, 413 S.W.2d 530 (Mo.App.1967), but has the burden of proving (1) that the other motorist was uninsured, (2) that the other motorist is legally liable to the insured, and (3) the amount of damages, Noland, supra; Hill v. Seaboard Fire & Marine Ins. Co., 374 S.W.2d 606, 609 (Mo.App.1963). The second element set out is equivalent to the statutory and contractual requirement that the insured be “legally entitled to recover”.
In Crenshaw v. Great Central Insurance Co., 527 S.W.2d 1, 4 (Mo.App.1975), the court stated that the insureds must show “that at the time [the] litigation against the insurer was commenced [the insureds’ action against the insurance company under the uninsured motorist clause] they . [the plaintiff was] . . . legally entitled to recover damages from the owner or operator of the uninsured highway vehicle.” (Emphasis added.) See also Byrn v. American Universal Insurance Co., 548 S.W.2d
