Section 6050 of the Code provides that-: “A defendant against whom an action is pending upon any contract for the payment of money may at any time before issue joined, make affidavit that a person not a party to the suit, without collusion with him; claims the money in controversy, and deposit the money in court, praying an order that such person be required, * * * to come in and defend.”
Then follow provisions for making such person a party to the suit, and for substituting him for the defendant, and for discharging defendant and relieving him— he having paid the money due on the contract into court —of all further liability to either of the parties in the contract, leaving the issue as to whose it is to be determined between the rival claimants. — Code, § 6050. While the remedy thus furnished by the statute is not ■exclusive, it was designed to afford means for accomplishing, in a more simple and convenient way, the objects and purposes of a bill of interpleader in equity; and the same principles which govern the applicability of such a bill govern the applicability of the statutory substitute. Where the former will not lie, the latter will not lie.—Coleman v. Chambers, 127 Ala. 618, 619, 29 South. 58; Nelson v. Goree, 34 Ala. 565, and other cases cited in citations under section 6050 of the Code.
*584One of the essential elements of the equitable remedy of interpleader, as laid down by our Supreme Court, and which, as seen, obtains with respect to the statutory interpleader, is that all the adverse titles or claims to the thing or debt in reference to which interpleader is prayed must be dependent upon or derived from a common source.—Kyle v. Mary Lee Coal Co., 112 Ala. 606, 20 South. 851. In the cases of adverse, independent titles, the party owing the debt or holding the property must protect himself by defending at law.—Gibson v. Goldwaite, 7 Ala. 281, 42 Am. Dec. 592. Consequently, a tenant may sustain an interpleader against his landlord and persons who claim rent in privity of contract or tenure with his landlord, as where the conflict is between the latter and one claiming the rent as his as-signee; but if a stranger, one claiming the rent independent of the landlord, brings suit therefor, interpleader cannot be maintained against him and the landlord. —11 Ency. PL & Pr. 451, 452, and cases cited; Kyle v. Mary Lee Coal Co., supra; Stewart v. Sample, 168 Ala. 270, 53 South. 182.
Applying these principles to the case at bar, it will be seen that the court did not err in declining to entertain the interpleader filed under section 6050 of the Code by the defendant in this action, which was a suit in as-sumpsit against him for damages for the breach of a certain written contract executed by him to one W. C. Murphy,- whereby he promised to deliver to said Murphy 2,000 pounds of middling lint cotton as rent, and which contract, it is alleged in the complaint, was transferred by said Murphy to the plaintiff (appellee here), and which was breached, it is alleged, by defendant in that he failed to deliver said cotton as promised. The defendant paid the value of the cotton into court and filed affidavit, as prescribed by said section 6050 of the *585Code, suggesting that one Sarah Murphy, without collusion with him, claimed the rent. The said Sarah Murphy immediately voluntarily came in and propounded her claim in writing, setting up therein, in substance, that the note sued on was given by the defendant, Davis, as rent for the year 1913 for certain land in Pike county, Ala., belonging to her at the time of the execution of said note, and which, before the execution thereof, she had rented to said Davis, hut had not taken his note for the rent, and that in order to procure his note for the rent for that year and the other years for which she had rented him the land, she sent her son, W. C. Murphy, the payee of the note here sued on, out to see said Davis, ivith instructions to have the latter execute his rent notes, payable to her, in conclusion of the agreement between her and said Davis; that her said son, instead of making all the rent notes which said Davis signed payable to her, as he had been instructed to do, made the one here sued on payable to himself, in violation of said instructions and without her authority or consent, and that she has never , ratified or approved the same. Clearly, if this be true, she has not now, and has never had, any title or claim whatever to the note here involved, or the supposed rent for which it was given, as it does not represent the rent due her, and its payment would not therefore relieve the defendant’s obligation to her for rent, for Avhich a note Avas not executed. He, having obtained possession of the premises through her by acknowledging her as his landlord and by agreeing to pay her rent, cannot escape liability therefor by executing a rent note, or even by paying such note, to a third party, without her authority, ratification, or consent. He dealt with her agent at his peril, and such agent’s acts, where not authorized in the first instance or subsequently ratified or approved, either expressly or *586impliedly, by her, are no more binding on ber than the acts of an entire stranger. Tbe defendant, Davis, by executing the note to claimant’s son without her authority or ratification, is in the attitude, therefore, of having out two obligations for the rent of the same land — one to the claimant not represented by any note, and one to her son represented by the note here sued on by his as-signee. Clearly, their respective claims to the rent are independent of each other, not traceable to or derived from a common source, no privity of contract or tenure being shown to exist between them; therefore an inter-pleader, the office of which is not “to protect against a double liability, but against a double vexation with respect to one liability,” cannot be maintained. — Ency. PL & Pr., supra, 451 452, 459; Kyle v. Mary Lee Coal Co., supra; Gibson v. Goldthwaite, supra; Conley v. Ala. Gold Life Ins. Co., 67 Ala. 472; Wilkinson v. Searcy, 74 Ala. 243; Hayes v. Johnson, 4 Ala. 267.
The proper practice probably was for the court to get rid of the claim by sustaining a demurrer to it rather than by striking it on motion.—Coleman v. Chambers, 127 Ala. 620, 29 South. 58. However, a decision of the question is not material to the disposition here of the case. Of course, if the claimant, Sarah Murphy, had either authorized or ratified the act of her son in taking the note payable to himself, then it would have represented the rent due her by the defendant, Davis, and the latter, in such case, when sued by the assignee of the son, could, if the claimant continued to assert a claim to the note or the rent represented by it, maintain inter-pleader. — Authorities supra.
It is true, as insisted by appellee, that the statute (Code, § 6050) permits the interpleader there provided for only in cases where defendant is sued on “a contract for the payment of money,” but a contract for the deliv*587ery of cotton as rent, when breached after demand and sued on for the value of the property as damages, becomes, we think, a contract for the payment of money within the contemplation of said statute.—Ragland v. Wood, 171 Ala. 145, 46 Am. Rep. 305; Ingram v. Bussey, 133 Ala. 539, 31 South. 967; Linam v. Jones, 134 Ala. 579, 33 South. 343; Hamil v. Flowers, 184 Ala. 301, 63 South. 994.
After the court declined to permit the defendant to interplead, the latter defended the suit under a plea of the general issue and a special plea setting up, in effect, that he entered and was in possession of the premises as the tenant of Sarah Murphy, and that the note for the rent thereof sued on was executed by him to her son without her authority, ratification, or consent, etc., practically the same facts as set up by Sarah Murphy in the claim she sought to propound as before adverted to. The legal effect of the plea was to set up a want of consideration for the note, which, not being a negotiable instrument — that is, one governed by the commercial law — was open to the same defenses in the hands of the assignee (the plaintiff, appellee) as in the hands of the original payee.
Ordinarily a tenant is estopped from denying the title to the premises of one whom he has acknowledged as landlord, and consequently from setting up, as against either, him or his assignee, that there is no consideration for a note executed by the tenant to such landlord as rent for such premises (18 Am. & Eng. Ency. Law [2d Ed.] 419, 420) ; but this general rule, like all others, is subject to several exceptions, among which is one applicable here, and that is, if the tenant did not receive the possession of the premises from such landlord, and was induced to acknowledge him as such through fraud, misrepresentation, or mistake, the tenant is not estopped *588from denying sucb landlord’s title, and consequently not estopped from pleading a want of considei’ation for a note given as rent for such premises.-18 Am. & Eng. Ency. Law (2d Ed.) 416, 417, 419, 420; Blakenship v. Blackwell, 124 Ala. 361, 362, 27 South. 551, 82 Am. St. Rep. 175; Davis v. Williams, 130 Ala. 534, 30 South. 488, 54 L. R. A. 749, 80 Am. St. Rep. 55; Farris v. Houston, 74 Ala. 162; Crim v. Nelms, 78 Ala. 608.
While, as to these matters, the special plea here does not meet all the requirements of a good plea, we do not think it open to either of the criticisms aimed at it by the'demurrer, which evidently misconceived the object and function of the plea. We are of opinion, therefore, that the court erred in sustaining the demurrer to the plea.
The court further erred in giving the affirmative charge and in rendering judgment for the plaintiff, since the complaint failed to state a substantial cause of action, in that it failed to allege, and the proof failed to show, a demand for the cotton, the value of which is sued for, before suit was brought. — Code, § 4143; Linam v. Jones, 134 Ala. 579, 33 South. 343; Ingram v. Bussey, supra; Ragland v. Wood, supra.
For the errors pointed out, the judgment is reversed.
