The parties offered and the court considered only the pleadings in determining defendants’ motions for judgment on the pleadings, summary judgment, and dismissal for failure to state a claim. It did not consider any “affidavits, depositions, answers to interrogatories, admissions, documentary materials, facts which are subject to judicial notice, [or] any other materials which would be admissible in evidence at trial.” Huss v. Huss, 31 N.C. App. 463, 466, 230 S.E. 2d 159, 162 (1976). Therefore, we must consider the ruling to have been under N.C. Gen. Stat. 1A-1, Rule 12(c) for a judgment on the pleadings and not under N.C. Gen. Stat. 1A-1, Rule 56 for summary judgment. Id.
Upon a motion for judgment on the pleadings the allegations of the non-movant are taken as true and all contravening assertions of the movant are taken as false. . . . Judgment on the pleadings is not favored by the law, and the non-movant’s pleadings will be liberally construed. . . . The trial court is required to view the facts and permissible inferences in the light most favorable to the non-movant. [Citations omitted.]
Id. Under N.C. Gen. Stat. 1A-1, Rule 12(h)(2), defendants’ motion for judgment on the pleadings properly included the defense of failure to state a claim upon which relief can be granted. We hold that plaintiffs have stated a claim.
“Actions to quiet title are governed by N.C. Gen. Stat. 41-10 . . . .” Boyd v. Watts, 73 N.C. App. 566, 571, 327 S.E. 2d 46, 50, disc. rev. allowed, 314 N.C. 114, 332 S.E. 2d 479 (1985). “This statute is remedial in nature, designed to provide a means for determining all adverse claims to land, including those formerly encompassed within the equitable proceedings to remove clouds on title.” Id. “Ordinarily, any person claiming title to real estate, whether in or out of possession, may maintain an action to remove a cloud from title against one who claims an interest in the *289property adverse to the claimant, and is required to allege only that . . . [defendants claim] an interest in the land in controversy.” Ramsey v. Ramsey, 224 N.C. 110, 113, 29 S.E. 2d 340, 342 (1944). However, while it is not necessary, except in cases of fraud, for plaintiffs to set forth the nature of defendants’ claim, “ ‘the adverse or beclouding character of the claim . . . should appear from the complaint.’ ” Id., quoting 44 Am. Jur., sec. 79, p. 63. In Lumber Co. v. Pamlico County, 242 N.C. 728, 729, 89 S.E. 2d 381, 381-82 (1955), plaintiffs complaint in an action to remove certain deeds as a cloud upon its title simply alleged that defendant receiver’s deed was void because the receiver lacked legal authority to convey. The Court held that the complaint stated a claim under N.C. Gen. Stat. 41-10 despite “plaintiff’s failure to allege specific facts showing the Receiver’s want of authority to convey . . . .” Id.
Plaintiffs here alleged that non-compliance with legal formalities voids the 16 June 1962 and 25 March 1969 deeds. They have not alleged fraud. Accordingly, despite failure to state specific facts underlying these allegations, the complaint nevertheless, under the liberal theory of notice pleading and in light of Lumber Co., is minimally sufficient to state a claim for relief.
“A judgment on the pleadings in favor of [defendants who assert] the statute of limitations as a bar is proper when, and only when, all the facts necessary to establish the limitation are alleged or admitted.” Flexolite Electrical v. Gilliam, 55 N.C. App. 86, 87-88, 284 S.E. 2d 523, 524 (1981). A preliminary question, however, is what statute of limitations, if any, applies to plaintiffs’ action. There is no express statute of limitations governing actions to quiet title under N.C. Gen. Stat. 41-10. It thus is necessary to refer to plaintiffs’ underlying theory of relief to determine which statute, if any, applies. See Oates v. Nelson, 269 C.A. 2d 18, 21, 74 Cal. Rptr. 475, 477 (1969).
Specifically, we must decide whether plaintiffs’ action is one to remove a cloud upon title or is essentially an action in ejectment. N.C. Gen. Stats. 1-38 and 1-40 are the applicable statutes of limitation for ejectment actions. Poultry Co. v. Oil Co., 272 N.C. 16, 19, 157 S.E. 2d 693, 696 (1967). These statutes prescribe “the period of time beyond which the owner of land is not privileged to bring an action ... for the recovery of his land from a person in *290possession thereof.” 7 Powell on Real Property, Sec. 1012[1] at 91-2 (1985 Supp.).
Actions to remove a cloud upon title are in essence ejectment actions and properly reviewed as such “ ‘where . . . defendants are in actual possession and plaintiffs seek to recover possession ....”’ Hayes v. Ricard, 244 N.C. 313, 320, 93 S.E. 2d 540, 546 (1956). Plaintiffs did pray the court that “defendants A. H. Van Dorp and Mary H. Van Dorp be required to account to the plaintiffs for the rents and profits derived from said land while in exclusive possession as tenants in common.” This prayer clearly implies that the individual defendants have been in actual possession of the subject property at some time. However, plaintiffs made no specific allegation that defendants were in actual possession at the time of the filing of this action. Likewise, plaintiffs did not seek specifically to recover possession in their demand for relief but merely prayed for rents and profits and removal of the deeds as a cloud upon their title. Under these circumstances we cannot find that plaintiffs’ action is in essence one for ejectment and therefore controlled by N.C. Gen. Stats. 1-38 and 1-40. Rather, we hold that plaintiffs’ action is one to remove a cloud upon title.
We further hold that no statute of limitations runs against plaintiffs bringing actions for removal of a cloud upon title. See Orange & Rockland Util v. Philwold Estates, 52 N.Y. 2d 253, 261, 418 N.E. 2d 1310, 1313 (1981); see also Oates v. Nelson, 269 C.A. 2d 18, 74 Cal. Rptr. 475 (1969). Such an action “ ‘is a continuing right which exists as long as there is an occasion for its exercise.’ ” Orange, 52 N.Y. 2d at 261, 418 N.E. 2d at 1313.
The purpose of a Statute of Limitations is to put an end to stale claims, not to compel resort to the courts to vindicate rights which have not been and might never be called into question. The requirement of prompt action is imposed as a policy matter upon persons who would challenge title to property rather than those who seek to quiet title to their land.
Id. Accordingly, we conclude that plaintiffs’ action is not barred by any statute of limitations.
We further hold that the doctrine of laches does not bar plaintiffs’ action. This doctrine “is more flexible than the statute *291of limitations, and may bar an equitable remedy by reason of inexcusable neglect or prejudicial delay . . . Huss, 31 N.C. App. at 469, 230 S.E. 2d at 163. “Delay which will constitute laches depends upon the facts and circumstances of each case.” Id. The pleadings here do not “disclose sufficient facts and circumstances to dispose of this case.” Id. Defendants’ allegation in their answer that “substantial improvements and betterments have been made to the land” does not establish this defense at the pleading stage.
The pleadings also fail to disclose sufficient facts and circumstances to permit judgment on the pleadings based on either estoppel or adverse possession. See Nationwide Mut. Insur. Co. v. Edwards, 67 N.C. App. 1, 6, 312 S.E. 2d 656, 660 (1984) (party claiming protection under rule of equitable estoppel has burden of establishing facts warranting its application); Board of Education v. Lamm, 6 N.C. App. 656, 660, 171 S.E. 2d 48, 51 (1969), affirmed, 276 N.C. 487, 173 S.E. 2d 281 (1970) (party claiming title by adverse possession has burden of proof on that issue).
Lastly, defendants’ answer raises the companion defenses of res judicata and collateral estoppel. Res judicata applies
when there has been a final judgment or decree, necessarily determining a fact, question or right in issue, rendered by a court of record and of competent jurisdiction, and there is a later suit involving an issue as to the identical fact, question or right theretofore determined, and involving identical parties or parties in privity with a party or parties to the prior suit.
King v. Grindstaff, 284 N.C. 348, 355, 200 S.E. 2d 799, 805 (1973), quoting Masters v. Dunstan, 256 N.C. 520, 124 S.E. 2d 574 (1962). “Under a companion principle of res judicata, collateral estoppel by judgment, parties and parties in privity with them — even in unrelated causes of action —are precluded from retrying fully litigated issues that were decided in any prior determination and were necessary to the prior determination.” Id. at 356, 200 S.E. 2d at 805.
We hold that res judicata does not apply to bar plaintiffs’ claims because they are unrelated to the earlier action in Poore v. Swan Quarter Farms, 57 N.C. App. 97, 290 S.E. 2d 799 (1982). There plaintiff Fred Poore brought an action in fraud against the *292defendants here seeking, in part, to set aside the 25 March 1969 deed to Mary Van Dorp as a fraudulent conveyance. The trial court granted summary judgment in favor of defendants, and this Court affirmed.
Plaintiffs’ action here, by contrast, is one under N.C. Gen. Stat. 41-10 to quiet title. Plaintiffs have not alleged fraud as grounds for extinguishing the 16 June 1962 and 25 March 1969 deeds. Non-compliance with legal formalities, not fraud, is the alleged basis for this action. Plaintiffs therefore have alleged a claim separate and distinct from that in Poore, supra, thereby precluding application of res judicata.
Likewise, the issue here as raised by the pleadings, viz, whether non-compliance with legal formalities voids the two deeds, was not fully litigated or decided in Poore and was not necessary to the determination there. King at 356, 200 S.E. 2d at 805. Accordingly, plaintiffs are not collaterally estopped from litigating it in this action.
For the foregoing reasons, we hold that the court erred by granting summary judgment in favor of defendants. The court’s order is therefore
Reversed.
Judges Eagles and COZORT concur.
