This is a venue case. The judgment of the trial court sustaining a plea of privilege is affirmed.
The plaintiff in the trial court, N. A. Andretta, appellant here, has appealed from the order of the District Court of Smith County sustaining the plea of privilege of the appellees, W. E. West and Willie B. West, resulting in the transfer of this case from Smith County where it was filed, to Van Zandt County, the residence of the appellees. All proceedings prerequisite to an appeal have been timely and regular, and the a.ppeal is properly before this Court.
Andretta, a resident of Smith County, alleged that the Superior Oil Company is a foreign corporation with a permit to do business in Texas with an agent or representative in Smith County, alleging in his original petition that the ap-pellees and Superior are jointly and severally liable to him for a ¼ proportionate part of certain monies paid to the Wests by Superior under the terms of a lieu royalty agreement entered into by the Wests and Superior. The Wests, husband and wife, fifed separate pleas of privilege to be sued in Van Zandt County, the county of their residence and domicile. Appellant duly filed controverting affidavits to the pleas of privilege asserting venue in Smith County pursuant to Subdivisions 27 and 29a, Article 1995, Vernon’s Ann. Texas St. Superior timely filed its original answer.
Andretta cast his suit in the form of an action for debt arising out of a, contract. His prayer is for recovery of $7,205.20, with interest and reasonable attorney’s fee. The allegations of his petition state, as the basis of his cause of action, that in 1942 West conveyed an oil, gas and mineral lease to Lack, covering a 100-acre tract in Van Zandt County, which by mesne conveyances passed to the Superior Oil Company; that in 1943 the Wests conveyed to Jenkins an undivided ⅛ royalty interest in oil, gas and other minerals mined or produced from the same 100-acre tract for a term of 20 years, etc., and that this interest was conveyed by Jenkins to Andretta; that in 1944 Superior secured oil production on a tract, not belonging to the Wests and not described in the lease or royalty deed or their assignments, adjoining the West tract; that in the same year Superior and the Wests entered into a contract in which Superior agreed to pay the Wests a lieu royalty equal in amount to ⅛ of the value of the production from the well on the adjoining tract in consideration of the Wests’ relinquishing their right to require Superior to undertake reasonable development under the oil, gas *771and mineral lease. Appellant attached to his petition and made a part of it for all purposes copies of the royalty deed and assignments which vested the royalty interest in him, the oil, gas and mineral lease and assignments which vested the leasehold estate in Superior, and the contract for lieu royalty between the Wests and Superior.
At the hearing, evidence was introduced and certain facts stipulated. The disagreement between the parties as revealed by their briefs lies in their construction of the nature of the suit, the appellant asserting that under the pleadings, proof and stipulations venue is fixed in Smith County by Subds. 27 and 29a of Article 1995, V.T.C.S.; the appellee taking the position that the suit requires an adjudication of title to land and that venue is controlled by Subd. 14. The Wests’ brief ignores the appellant’s contention respecting the application of Subds. 27 and 29a. Andretta’s one point of error is that the trial court erred in sustaining the Wests’ pleas of privilege. The point of error must be overruled because the judgment of the trial court is correct.
This Court will consider first the appellant’s contention that the record established venue in Smith County. Subd. 27 of the venue statute provides that "foreign corporations * * * doing business within this State, may be sued * * * in any county where such company may have an agency or representative * * The pleadings and facts established without controversy that Superior Oil Company is a foreign corporation doing business within the State with an agency or representative in Smith County. Subd. 27 does not require proof of a cause of action against a foreign corporation. Southwestern Greyhound Lines, Inc., v. Day, Tex.Civ.App., 238 S.W.2d 258, n. w. h.; 1 McDonald Civil Practice, Sec. 4.30 at p. 399. The foregoing establishes venue as to Superior in Smith County.
Without applying his reasoning to the record in this case, the appellant asserts that under the pleadings, proof and stipulation the Wests are necessary parties to the suit against Superior and that as such under Subd. 29a the suit may be maintained against them in Smith County. That contention will be examined. In Ladner v. Reliance Corp., Tex., 293 S.W. 2d 758, at page 761, the Supreme Court said:
“Exception 29a is one which is never considered alone, but always in conjunction with some other subdivision of the statute. A plaintiff who relies upon this exception must therefore allege and prove: (1) the venue facts which show that the suit is maintainable where brought against at least one defendant under another subdivision of the statute, and (2) that the remaining defendants, whom he seeks to hold under Subdivision 29a, are necessary parties to the suit within the meaning of that subdivision.”
And in that same opinion, beginning at the bottom of page 763, is found this statement:
“ * * * It is our opinion that a plaintiff who relies on Subdivision 29a to maintain venue of a defendant in the county of suit must not only allege the facts which make such defendant a necessary party to the suit within the meaning of that subdivision, but must also prove by independent evidence all of such facts except those which are taken as admitted under the pleadings or which are established as a matter of law by the allegations of the petition.”
As the Ladner case is understood, there must be pleadings and proof of (1) a joint cause of action against Superior and the Wests in which the Wests must necessarily be joined in order for Andretta to secure the full relief to which he might be entitled in the suit against Superior; or (2) *772that the Wests have an interest in the suit which could be affected by any decree completely adjudicating the rights of appellant and Superior; or (3) that no effectual decree could be rendered without joining Superior and the Wests.
Reference must be made to the pleadings and the evidence first to determine whether a joint cause of action is pled against Superior and the Wests which would entitle the appellant to a joint judgment against the two defendants. Appellant casts his petition in the form of an (a) action upon debt arising out of a contract; (b) and pleads the contracts upon which he relied to establish a recovery; and (c) prays for a joint and several judgment. If Superior is indebted to Andretta, it is because of the terms of the original mineral lease construed in connection with the lieu royalty contract. If the Wests are indebted, to him it is because of their violation of the warranty of their deed conveying ¼ of the royalty construed in connection with the lieu royalty contract. It seems that the proof necessary to establish a cause of action against Superior would include substantially all that is necessary to establish a cause of action against the Wests under the appellant’s theory of the case.
From the foregoing recitation of the gravamen of the action against Superior and against the Wests it is obvious that their liability to the appellant is not joint and that recovery against each is upon independent grounds, neither of which embraces the other.
Next, inquiry is directed to Subd; 2 and 3 of the rule from the Ladner case, supra, stated in a previous paragraph and unless the necessity of construing the lieu royalty contract brings the Wests within either 2 or 3, the Wests are not necessary parties. Subd. 3 may be eliminated because the .relief sought is a money judgment' and it, of course, would be effectual without thp Wests. Left only is the question (relating to 2 above) as to whether the Wests have an interest in the subject-matter of the suit which could be affected by any decree completely adjudicating the rights of Superior and Andretta.
It has been held that the party obligated to pay a commission under a contract is not a necessary party to a suit in which the person entitled to receive the commission is being sued for a part of the commission . by a third party not privy to the commission contract. Hoover v. Hamilton, Tex.Civ.App., 14 S.W.2d 935, wr. ref.; Richards v. Smith, Tex.Civ.App., 239 S.W.2d 724, wr. ref. The Supreme Court in City of Austin v. Cahill, 99 Tex. 172, 88 S.W. 542, and in Wichita County v. Robinson, Tex., 276 S.W.2d 509, held that even though under the stare decisis doctrine certain persons might be affected in their own rights by harmful precedent, they are not necessary parties to the proceeding in which the harmful precedent might be set. In Orr v. Whitney, 241 S.W.2d 981, at page 982, wr. ref., it is said: “ * * * one js not a necessary party where his presence is in no way essential to a determination of the respective rights of the plaintiff or the defendant.” In view of these authorities, it does not appear that the Wests are necessary to a suit to determine the respective rights of Superior or Andretta. This view is strengthened when it is considered that the lieu royalty agreement appears to be clear and unambiguous on its face and there is neither pleading nor proof in the record that it is ambiguous and a construction of the instrument is dependent upon proof of matters outside the instrument. Under these circumstances, the Wests, though proper parties, are not indispensable and should not be deprived of the valuable right of being sued in the county of their residence when the record does not show that their presence in Andretta’s suit against Superior will contribute anything to a proper determination of Andretta’s and Superior’s rights or that it might result in a judgment affecting them. It may be assumed that the law is constant and *773any determination of the law upon the pleadings, the instruments and .the evidence reflected by this record will be the same upon the same pleadings, instruments and evidence in a suit between different parties. Therefore, it cannot reasonably be said that Superior is caught up in a situation where an unconscionable result might be reached; that is, Superior be compelled to pay Andretta ⅛ of the royalty under the lieu royalty contract and the Wests the entire royalty under the same contract.
The trial court judgment may also be sustained for reasons not briefed but apparent from the record. The appellant incorporated the oil and gas lease from the Wests, now held by Superior, into his petition as a part thereof and for all purposes. The oil and gas lease has a provision reading as follows:
“The estate of either party hereto may be assigned in whole or in part and as to any mineral. All the covenants obligations and considerations of this lease shall extend to and be binding upon the parties hereto, their heirs, executors, administrators, successors, assigns and successive assigns. No change or division whatsoever and howsoever arising or effected, in the ownership of said land, royalties, delay rentals or other moneys shall operate to increase the obligations or dimmish the rights of lessee hereunder; and notwithstanding any other actual or constructive knowledge of or notice to lessee thereof, no such change or division shall be binding upon lessee unless and until thirty days after written notice thereof from both lessor and lessor’s successors and assigns, in which all such parties in interest concur, and certified copies of recorded transfers or assignments, in the event such division or change is accomplished in such manner, shall have been delivered to the record owner of the lease at its principal place of business. * * * ” (Emphasis added.)
It is thought that compliance with the above-quoted provision of the lease is a condition precedent to Superior’s liability to Andretta for royalties under the oil lease. In Houston Land & Trust Co. v. Shelton, Tex.Civ.App., 69 S.W.2d 796, at page 801 wr. dis., it is said:
“ * * * If a right as it usually exists is one dependent upon a condition, or — what is the same thing— is unconditional only when exceptional circumstances exist, in either case plaintiff, seeking to enforce such right, must, in order to state a right of action, either allege the facts to show the exceptional circumstances or the existence of the condition upon which the right depends:”
See also Automobile Ins. Co. v. Bridges, Tex.Civ.App., 5 S.W.2d 244, n. w. h.; Hutchins v. Wade, 20 Tex. 7; Northern Texas Utilities Co. v. Community Nat. Gas Co., Tex.Civ.App., 297 S.W. 904; subsequent appeal, Tex.Civ.App., 13 S.W.2d 184; Sweetwater Progressive Mut. Life & Acc. Ass’n v. Allison, Tex.Civ.App., 22 S.W.2d 1107. Rule 54, Vernon’s Ann.Texas Rules, does not change the rule, it merely provides that pleadings will be sufficient if they aver generally that all conditions precedent have been performed or have occurred. See Southwestern Associated Telephone Co. v. City of Dalhart, Tex.Civ.App., 254 S.W.2d 819, wr. ref., n. r. e.
That the quoted provision is a true condition precedent as between An-dretta and Superior seems clear. The American Law Institute Tentative Restatement of the Law, Contracts, No. 6, Sec. 246, p. 9, defines a condition precedent as “a fact which must exist before a duty of immediate performance of a promise arises.” Usually where the consideration for the contract is executed or an estate or interest passed or vested immediately upon the making of the. contract *774subject to be defeated by matter ex post facto, a condition precedent does not exist. Here, however, by provision of the oil lease to which Andretta was privy there is an express stipulation and agreement that between Andretta and Superior no title binding upon Superior will pass or vest by reason of the royalty deed until Superior is given notice in the manner the lease requires. Andretta’s pleadings incorporating this provision of the contract causes the pleading to show upon its face the requirement of notice but wholly fails to allege that such notice has been given or that the giving of the required notice has in any wise been excused. The principle of non-liability of the owner of the leasehold estate under the mineral lease in the absence of contractual notice is well established by such authority as Shell Petroleum Corp. v. Royal Petroleum Corp., 135 Tex. 12, 139 S.W.2d 753; Tide Water Associated Oil Co. v. Hammer, Tex.Civ.App., 163 S.W.2d 232, wr. ref., and see Jackson v. United Producers Pipe Line Co., Tex.Civ.App., 33 S.W. 540, wr. ref.; 31-A, Tex.Jur. 473, Sec. 263.
Undoubtedly Subd. 27 of the venue statute requires Andretta to allege a cause of action. Aside from any authority, it is patent logic that a cause of action under Subd. 27 must be stated in order to determine whether under Subd. 29a other parties to the suit are necessary, proper or mis-joined. No one would argue that a party could be necessary to a suit in which no relief may be had.
The conclusion reached has the effect of sustaining the appellees’ counter-point and discussion thereof is not required. Appellant’s point of error is respectfully overruled.
The judgment of the trial court is affirmed.
