¶1This appeal is from the trial court’s dismissal of Defendant’s Rule 29.15 motion. We affirm.
¶2Defendant was charged by indictment on August 27, 1983, with the shooting death of William Parr, a 62-year-old cab driver in St. Louis. The shocking facts giving rise to that indictment are detailed in State v. Malone, 694 S.W.2d 723 (Mo. banc 1985), cert. denied, 476 U.S. 1165, 106 S.Ct. 2292, 90 L.Ed.2d 733 (1986). On March 30, 1984, following the trial on the merits, the jury found Defendant guilty of capital murder. The following day, the same jury assessed the punishment at death and on April 26, Defendant was formally sentenced to death by the trial judge. On direct appeal Defendant’s conviction and sentence were affirmed. State v. Malone, supra, at 728.
¶3Defendant filed a Rule 27.26 motion on July 3, 1986, to set aside his conviction and sentence and on March 13, 1987, filed his first amended motion. Neither was verified nor signed by Defendant. The State moved to dismiss alleging that Defendant was currently incarcerated in California and was therefore not “in custody” in Missouri as required by the rule. The trial court sustained the State’s motion and the court of appeals in Malone v. State, 747 S.W.2d 695 (Mo.App.1988), held the dismissal of the Rule 27.26 motions was proper but such did not bar Defendant, sentenced prior to January 1, 1988, from seeking relief within the June 30, 1988, deadline of Rule 29.15(m). Defendant’s counsel during this Rule 27.26 motion period was Dorothy *150Hirzy of the Special Public Defenders Office.
¶4While Defendant remained incarcerated in California, Hirzy continued her contacts by telephone and correspondence and at Defendant’s request filed a Rule 29.15 motion with the circuit court on May 20, 1988. This motion was neither signed nor verified by Defendant but was instead signed by Hirzy. Sometime after the June 30, 1988, deadline, someone in the Special Public Defenders’ office became aware the motion was neither signed nor verified as required by the rule and sent a verification form to Defendant in California. He apparently executed this form July 19 but from the record before us, it does not appear to have been filed with circuit court. No explanation is given for this failure.
¶5Assuming defendant had a right, by virtue of filing the unverified motion, until 30 days following May 20 to file an amended motion, the court granted thirty additional days to permit such action. Accordingly, on July 20, 1988, under Rule 29.15(f), Hirzy filed Defendant’s first amended Rule 29.15 motion but this motion too was neither signed nor verified by Defendant. On January 12, 1989, an evidentiary hearing was conducted in which the trial court, ruling on the merits of Defendant’s claim, denied Defendant’s motions. Defendant appealed and this Court originally considered the matter in late 1989. During the appeal, the State challenged the original and the amended unsigned and unverified motions as insufficient under Rule 29.15(d).
¶6Faced with an incomplete record, we remanded the cause directing the trial court to conduct an evidentiary hearing and determine whether the Defendant complied with the verification provisions of Rule 29.-15 and whether Defendant’s trial jury was impaneled contrary to the teachings of Batson v. Kentucky, 476 U.S. 79, 106 S.Ct. 1712, 90 L.Ed.2d 69 (1986) and State v. Antwine, 743 S.W.2d 51 (Mo. banc 1987) as suggested by Defendant in his Rule 29.15 motions.
¶7On January 19, 1990, the trial court conducted the requested evidentiary hearing and on February 20, Defendant filed a motion for leave to supply verification for his original and amended motions. This request was denied by the trial court.
¶8On March 26, 1990, the trial court ruled against Defendant on his Batsonand Ant-wine challenges and further held: “Personal verification by Movant is a jurisdictional requirement for any action filed under Rule 29.15_ Movant’s failure to file a properly verified motion on or before June 30, 1988, deprives this Court of jurisdiction to hear this matter and requires dismissal.” It is from this judgment that Defendant appeals.
¶9Defendant had been sentenced on April 26, 1984, and did not effectively seek relief under Rule 27.26
¶10The content and form of the motion to be filed are delineated by Rule 29.15(d) which states:
The motion to vacate shall include every ground known to the movant for vacating, setting aside, or correcting the judgment or sentence. The movant shall verify the motion, declaring that he has listed all grounds for relief known to him and acknowledging his understanding that he waives any ground for relief known to him that is not listed in the motion.
¶11(Emphasis added.) Further, Rule 29.15(f) requires that “[a]ny amended motion shall be verified by movant (emphasis added)” and'29.15(b) provides that motions filed under the rule are to be substantially in the form of Criminal Procedure Form 40. Defendant’s pro se motion does not so conform but had Defendant employed the form provided he would have noted it contains instructions that the motion is to be *151“signed by the movant and verified (notarized)”. The form contains a signature line for movant and the appropriate space for acknowledgment. Simply stated, the unverified motion is not substantially in the form required by Form 40. Defendant failed to meet Rule 29.15’s mandatory requirements,
¶12The fact that he was afforded an evidentiary hearing on the merits of his claim is not helpful to Defendant, for verification is a jurisdictional requirement under Rule 29.15, State v. Mitchell, 789 S.W.2d 55 (Mo.App.1990); see also Hill v. State, 783 S.W.2d 501 (Mo.App.1990) (motion filed under Rule 24.035), and jurisdictional questions may be raised at any time. Wescott v. State, 731 S.W.2d 326, 327 n. 2 (Mo.App.1987). Though the State challenged the motions’ want of verification for the first time on appeal, such does not preclude consideration of the issue.
¶13The verification requirement is not a shallow gesture of form over substance, for:
The obvious purpose of the verification requirement ... is to discourage frivolous and unfounded allegations which must be addressed by trial courts already over burdened with a proliferation of post-conviction remedy motions.
¶14West v. State, 787 S.W.2d 856, 857 (Mo.App.1990). To require verification of a pro se and amended motion places no undue burden on the movant, who need only sign and have his signature acknowledged. It gives pause to those who would mislead the court or abuse the system but creates no bar to those with reasonable bases for such claims. Further, an important aspect of the rule is to discover and adjudicate all claims for relief in a single proceeding.
¶15Rule 29.15(m) established the deadline of June 30, 1988, for those situated as defendant here to seek post-conviction under the rule. This contemplates that the motion filed will be in compliance with Rule 29.15(d), and because Defendant failed to do so, his “pro se” motion filed on May 24, 1988, was a nullity. Quinn v. State, 776 S.W.2d 916 (Mo.App.1989). In sum Defendant failed to meet the June 30 deadline. His first request to amend his motion and to sign and verify came February 20⅞ 1990, more than a year and a half following expiration of the deadline. The same bar applies to Defendant’s first amended Rule 29.15 motion. The time limits of Rule 29.15 are valid and mandatory. Day v. State, 770 S.W.2d 692, 695 (Mo. banc 1989), cert. denied, — U.S. —, 110 S.Ct. 186, 107 L.Ed.2d 141 (1989). Failure to meet the scheduled deadline foreclosed Defendant’s right to proceed. Id. at 696.
¶16Judgment affirmed.
¶17. As previously noted Defendant's original filing under Rule 27.26 was dismissed without prejudice by the trial court and that ruling was affirmed by the court of appeals. The effect of such dismissal was to create a situation as though no relief had been sought under Rule 27.26 for purposes of the deadlines contained in Rule 29.15(m).
¶18. Under Rule 27.26 the filing of an unverified motion had long been held unacceptable and a ground for dismissal. State v. Rector, 547 S.W.2d 525, 526 (Mo.App.1977); Riley v. State, 588 S.W.2d 738, 741 (Mo.App.1979). This was so because verification was held to be mandatory and jurisdictional. Mills v. State, 769 S.W.2d 469, 470 (Mo.App.1989). See however, Rodden v. State, 795 S.W.2d 393 (Mo. banc 1990).
