This is an action of trespass to try title to a tract of land lying in Cherokee county, instituted by John Conner, one of the appellees, for the use and benefit of Mary Conner, his wife, as her next friend. The land is averred in the petition to he the property of Mary Conner, and her title is solely relied on for a recovery. Several years after the commencement of the suit, by an amendment, Mary Conner was made a formal party plaintiff to the suit with her husband. There were a trial, verdict, and judgment, for the appellees, who were plaintiffs in the court below. Various exceptions were taken during the progress of the trial, by the appellant, to the rulings of the court, on which assignments of error are made in this court. Such of them will be considered as are deemed material to a proper disposition of the case.
The court below did not err in overruling the appellant’s excéptions to the, amended petition, making Mary Conner a formal party plaintiff to the suit. The power to grant amendments, when not forbidden by law, is a discretionary power in the court, which an appellate court will not in *109general revise, especially when the amendment is of such a character as does not surprise, hinder, or delay the opposite party. (Austin & Clapp v. Jordan, 5 Tex., 133.) Such is believed to be the character of the amendment in question. It was optional with the appellee, John Conner, to sue alone, or join his wife with him, as the action is for the recovery of what is alleged to be her separate property. (Hart. Dig., Art. 2415, [Paschal’s Dig., Art. 4636, Note 1043;] Cannon v. Hemphill, 7 Tex., 184; Bartlett v. Cocke, 15 Tex., 471.)
As at first brought, this was really a suit by John Conner alone; his description of himself in his petition, as “next friend” of his wife, was mere surplusage. The averments of the petition, to which we must look to determine its character and objects, shows it to have been a suit in which the husband was seeking the recovery of separate property of his wife for her use and benefit, as he was authorized by law to do.
Looking to the substance, and not to the form of the proceeding, and rejecting verbal surplusage, which could have had no manner of influence on the rights of either the plaintiffs or defendants below, it is believed that the subsequent amendment, by which Mrs. Conner was made a party to the suit, effected no change whatever in its character, and was therefore entirely immaterial, and could give the appellant no just ground of complaint.
The exclusion by the court of the translated copy of the testimonio of the Musquez title, offered in evidence by the defendant, is assigned as error. In this ruling we are of opinion that the court did not err. A translation is admissible in evidence only on the supposition that the original document could be offered in evidence without proof of its execution. (Houston v. Perry, 3 Tex., 393; same case, 5 Tex., 464.)
It is well settled, that the execution of a testimonio of title must be proved before it is admissible as evidence. *110(Paschal v. Perez, 7 Tex., 348; DeLeon v. White,,9 Tex., 589; Titus v. Kimbro, 8 Tex., 210; Word v. McKinney, Galveston T., 1860,) [25 Tex., 258.]
The original of this copy offered in evidence is private property, and the evidence in this case shows it to be in possession of a party bearing the same name of one of the parties alleged by the defendant to be the owners of the land covered by the Musquez title. It seems to have been deposited in the general land office to be recorded, and, while there, this translated copy was made, and the original document itself was subsequently withdrawn.
The commissioner of the general land office is authorized to give certified copies, to be read in evidence, of all records, books, and papers, the legal custody of which belongs to his office. But his certificate will not give legal authenticity to papers which are mere private property, and which do not belong to or constitute archives of his office. (Herndon v. Casiano, 7 Tex., 322; Paschal v. Perez, 7 Tex., 348.)
"Various instructions were asked by the appellant on the trial and refused by the court, and their refusal is assigned as error. We are of opinion that the court did not err in refusing them. So much of them as was proper to be given had been substantially embodied in the general charge already given to the jury.
It was sought on the trial by the appellant to defeat a recovery by the appellees, whose pleadings aver the title to the land to be solely in Mrs. Conner, by establishing one of two propositions: First, that the Simpson head-right certificate, by virtue of which Mrs. Conner claims the land in controversy, is community, and not her separate property; or, second, that the appellees, John and Mary Conner, own the certificate in equal interests, by inheritance from Uriah Conner, their deceased son. Instructions intended to make these points before the jury were asked by the appellant, and we think properly refused *111by the court. It is not questioned but that, when the husband joins the wife in a suit to recover property as the separate property of the wife, a recovery cannot be had, unless the property be proved to belong to the wife, although it be proved to belong to the husband. (Owen v. Tankersly, 12 Tex., 413; Moffatt v. Sydnor, 13 Tex., 628.)
In such a case the right of the wife only is in issue, and it would be a departure from elementary principles to permit a recovery on any other title. It is simply intended to say, that in this case the facts do not warrant such instructions as were asked. The proof is ¿hundant, clear, and uncontradicted, that the title to the certificate was made to Mrs. Conner by Simpson, in satisfaction and discharge of his title-bond to Uriah Conner, which was delivered up to him at the time; that Mrs. Conner did not pay one cent for it, and that John Conner knew, approved, and consented to the conveyance to his wife, and has ever since spoken of it and treated it as his wife’s separate property; and he distinctly, in this suit, alleges it to be hers, and seeks a recovery of the land alone on her title. John Conner alone had a right to contest the validity of the gift by Uriah to his mother. He alone had a right to object to the conveyance by Simpson to her of the certificate in satisfaction of the title-bond. Having acquiesced in and consented to it, he thereby invested her with the title to his interest as completely as he could have done by the most solemn deed of gift. He is estopped from denying her title. (Story v. Marshall, 24 Tex., 307; Owen v. Tankersly, 12 Tex., 411.)
A purchaser from him, without notice of the rights of his wife, or a creditor only, would have a right to question the validity of Mrs. Conner’s title. Certainly a stranger, occupying the position of the appellant, can have no such right. Ho defense which the appellant could make to this action, no right which he could set up, has been cut off or impaired by the relinquishment of John Conner of his *112interest in this certificate to his wife. It is true that the appellant alleges in his answer that John Conner represented the Musquez or Allen & Dexter title to this land to he good, and induced him to purchase and pay out his money for it; but of this there is not a particle of proof. In short, the record does not disclose a single fact which tends to place the appellant in a position to interfere with or complain of the gift from Conner to his wife. Mrs. Conner’s rights as against her husband were perfect, so far as the record shows, before the commencement of this suit, and the court very properly refused instructions which would imply that the contrary might be the case, when there was no evidence on which to predicate such a proposition. (Chandler v. Van Roeder, 24 How., 444; Austin v. Talk, 20 Tex., 155; Thompson v. Shannon, 9 Tex., 562.)
The general charge of the court is assigned as error. The assignment is so general, indefinite, and vague as not to be entitled to consideration, and we might well decline to regard it as an assignment of error, as it fails to specify the errors relied on. (Earle v. Thomas, 14 Tex., 583; Allen v. Stephanes, 18 Tex., 658.)
■ Upon an examination of it, however, while we perceive some errors and inaccuracies, none of them are deemed prejudicial to the rights of the appellant, or of such a character as to require a reversal of the judgment.
The overruling by the court of the motion for new trial is assigned as error. We are of opinion there was no error in refusing this motion. The verdict of the jury is, as we have seen on the question of title, in accordance with the law and the evidence. We are of opinion that it is equally so on the appellant’s suggestion of improvements in good faith. The testimony shows very clearly that the value of the use and occupation of the land exceeds the value of the improvements. The appellant certainly has no right to complain of the verdict on this issue. Still less reason has *113he to complain of the charge of the court on this point. The jury were instructed in substance, that, if the appellant honestly believed his title to be good, or that his vendor’s title was good, he was entitled to the value of his improvements, &c. This is clearly erroneous with reference to the facts of this case, as it is not pretended that the appellant has shown that either he or his vendor hold by any claim or title derived from the government. It is difficult to perceive how a party can honestly believe that his title is good, or how his possession can be in good faith, when he is unable to trace his title back to the government, the only source of title to land. While a defective or irregular apparent title may be the basis of a recovery for improvements made in good faith, a void title (if such an expression may be used) cannot be. (Rogers v. Bracken, 15 Tex., 568; Robson v. Osborn, 13 Tex., 298; Pitts v. Booth, 15 Tex., 454.)
The ground of the motion for new trial, principally relied on, is the discovery alleged to have been made after the commencement of the trial, of the testimonio of the Musquez title, a copy of which was offered and excluded on the trial. ' The motion is accompanied by the affidavit of Thomas J. Allen, who swears that he has the original document in his possession; that he exhibited it to the appellant at a time, too late for the trial of the cause; that appellant requested the use of it, and he refused it, because it was too late to file it and give notice, or to prepare proof of its execution, as the witness lived in another county. The appellant accompanies his motion with an affidavit, which states that he used due diligence to procure this testimony, without stating the acts of diligence.
It is incumbent on a party who asks a new trial on the ground of newly-discovered evidence to satisfy the court, first, that the evidence has come to his knowledge since the trial; second, that it was not owing to the want of due dil*114igence that it did not come sooner; third, that it is not cumulative; fourth, that it is so material that it would probably produce a different verdict if the new trial were granted. (3 Gr. & Wat. on New Trials, 1021; Burnley v. Rice, 21 Tex., 180.)
These requisites must concur to entitle the motion to prevail; a failure of anyone of them is fatal. So far from conforming to these requirements, the motion and affidavits expressly negative the idea that a knowledge of the existence and whereabouts of the document in question came to appellant since the trial. With full knowledge of the facts he went to trial, without asking a continuance to enable him to make better preparation.
If the testimony had been discovered since the trial, and the motion filled the requirements of the law on that point, it is fatally defective in not showing that the appellant ever made an effort, or used any diligence to discover it before. It has been repeatedly held by this court, that alle'gations of diligence amount to nothing, but that the facts which constitute -it must be averred, so that the court can decide for itself what amount of diligence, if any, has been used. Ho single fact of the kind is alleged in the motion. This suit has been pending since October, 1851. Certainly there was time enough to make preparation for trial. Having neglected to do it, the appellant cannot justly ask to be excused from the consequences of his own negligence, nor has he a right to complain, or to demand to be allowed a .second opportunity to do what he could as well have done at first. If he has merit in his defense, it is his own fault that the record does not show it, the consequences of which he must bear. The appellees proved a location and survey of the land in controversy by virtue of a genuine and valid certificate, the title to which is in Mrs. Conner. The appellant showed no title in himself, nor did he prove title outstanding in any third person. The judgment is a cor*115rect legal conclusion from the pleadings and proof. The other points raised by the assignment of errors are not deemed of sufficient importance to require notice.
There is no error in the judgment requiring its reversal, and it is therefore
Aeeirmed.
