We consider three appeals from denials of petitions for appointment of counsel under 28 U.S.C. § 1915(d). The appeal consolidates three independent in forma pauper-is civil rights actions brought by prison inmates pursuant to 42 U.S.C. § 1983. Each plaintiff moved the district court for appointment of counsel, but in each case, the motion was denied. Plaintiffs appeal from the denial of these motions. Two issues are presented on appeal: (1) whether the denials of motions to appoint counsel in these eases are appealable orders under 28 U.S.C. § 1291 and if so, (2) whether the decision to deny appointed counsel in any or all of the three cases was appropriate. We first conclude that denial of counsel in a civil rights case is appealable as a final collateral order. Finding jurisdiction, we remand each case on the merits for more detailed findings by the district court as to why appointment of counsel was denied.
FACTS
The first of the three cases in this consolidated appeal was brought in December 1981, by Johnny W. Robbins, an inmate at the Louisiana State Penitentiary. Robbins brought suit under 42 U.S.C. § 1983, alleging that he had been denied competent medical assistance, and that he had been denied an appropriate diet. Robbins’ suit was filed in forma pauperis, and referred to a United States magistrate.
Robbins moved for appointment of counsel under 28 U.S.C. § 1915(d)1. In December 1982, the magistrate denied plaintiff’s motion for appointment of counsel. Over a year later, in April 1983, the magistrate again denied a motion for appointment of counsel, stating in a minute entry that “this case is not too complex for presentation by the plaintiff ... [and] plaintiff is capable of properly investigating this case.”
Thereafter, on April 22, 1983, Robbins filed a notice of appeal stating that review was sought “by the United States Court of Appeals for the Fifth Circuit from the final judgment entered in this action, denying plaintiffs an attorney on the 7th day of April, 1983.” On April 26, 1983, four days after Robbins filed the notice of appeal, the district court affixed a handwritten order to Robbins’ certificate for appeal, pursuant to Fifth Circuit Rule 24.2 The order stated:
Petitioner seeks to appeal from an order of the magistrate who refused to appoint counsel to referenced petitioner in this § 1983 action. There was no abuse of discretion on the part of the magistrate. The Court finds petitioner is not entitled to counsel at this time in this suit.
*408Robbins did not file a formal notice of appeal from the April 26, 1983, district court order. On May 24, 1983, however, Robbins did file in this Court a document entitled “MOTION TO PROCEED ON APPEAL IN FORMA PAUPERIS.” At issue is whether either of the motions filed by Robbins satisfies the requirements for proper notice of appeal from the April 26, 1983, district court order.
The second plaintiff, Charles Edward Bolden, filed a pro se complaint under 42 U.S.C. § 1983 in March 1983. Bolden alleged inadequate medical treatment while incarcerated at the St. Martin Parish Jail.3 Named as defendants were Steve Champagne, Warden of the St. Martin Parish Jail; Earl Dundas, a nurse at the jail; and Dr. Willis Bienvenue, a physician at University Medical Center. In May 1983, Bolden moved for appointment of counsel. The motion was supported by an affidavit stating that “I can not read or write to good and in a case like this I don’t no all my right.” The district court denied Bolden’s motion on June 15, 1983, concluding that “this is not such an exceedingly complex case that Plaintiff will not be able to adequately represent himself.” Bolden timely filed this appeal.
The third and final plaintiff, Kenneth James Midkiff, filed a § 1983 suit in forma pauperis in May 1983. Midkiff alleged that he had suffered a broken hand while incarcerated at the Lafayette Parish Jail, and that he had not received proper medical attention. In an affidavit attached to the complaint, Midkiff moved for appointment of counsel pursuant to 28 U.S.C. § 1915(d) stating that “I will not be able to file any other papers, and do not have law books to look up case law.” Midkiff has a high school education.
In June 1983, the district court denied Midkiff’s motion for appointment of counsel, concluding that the case was not overly complex. Midkiff filed timely notice of appeal from the district court order on June 23,1983. On that same day, Midkiff filed a second federal lawsuit, based on the same facts as the first suit4, against Joseph C. Duhon, Warden of the Lafayette Parish Jail, and Brett Pryor, jailer. Midkiff simultaneously made a motion for appointment of counsel, alleging that the case was serious and that “[I] have no law understand what so ever.”
On July 6, 1983, the magistrate consolidated Midkiff’s two suits, and denied Midkiff’s motion for appointment of counsel. Midkiff timely filed this appeal.
I. NOTICE OF APPEAL
We must first decide whether the appeal of appellant Robbins is timely. Robbins failed to file a document constituting a timely notice of appeal pursuant to Rule 4(a) of the Federal Rules of Appellate Procedure. Rule 4(a) requires that a notice of appeal “be filed with the clerk of the district court within 30 days after the date of the entry of the judgment or order appealed from.” The time limitation for filing a notice of appeal is jurisdictional and lack of a timely notice mandates dismissal of an appeal. Griggs v. Provident Consumer Discount Co., 459 U.S. 56, 103 S.Ct. 400, 403, 74 L.Ed.2d 225 (1982). Williams v. Treen, 671 F.2d 892, 895 (5th Cir.1982), cert. denied, 459 U.S. 1126, 103 S.Ct. 762, 74 L.Ed.2d 977 (1983). We do accept the filing of certain documents other than a formal notice of appeal, if filed within the thirty day limit of Rule 4(a), as the substantial equivalent of a notice of appeal.
This Court has repeatedly held that a request to proceed in forma pauperis satisfies the filing requirement for notice of appeal. See Causey v. Civiletti, 621 *409F.2d 691 (5th Cir.1980); Cobb v. Lewis, 488 F.2d 41 (5th Cir.1974); Tillman v. United States, 268 F.2d 422 (5th Cir.1959). Plaintiff Robbins’ motion to proceed in forma pauperis was filed within the thirty day period following the district court’s denial of appointment of counsel, and as such, we accept it as the substantial equivalent of a timely notice of appeal.5
II. JURISDICTION
We next address the question of our jurisdiction over these appeals. Section 1291 of 28 U.S.C. provides, “[t]he courts of appeals shall have jurisdiction of appeals from all final decisions of the district courts of the United States ... except where a direct review may be had in the Supreme Court.” (emphasis added). A final decision for purposes of § 1291 has been defined as “a decision by the District Court that ‘ends the litigation on the merits and leaves nothing for the court to do but execute the judgment.’ ” Coopers & Lybrand v. Livesay, 437 U.S. 463, 467, 98 S.Ct. 2454, 2457, 57 L.Ed.2d 351 (1978) (quoting Catlin v. United States, 324 U.S. 229, 233, 65 S.Ct. 631, 633, 89 L.Ed. 911 (1945)). Appellees argue that an order denying counsel does not prevent a litigant from presenting a pro se claim to the court. Since such an order does not end the litigation on the merits, it cannot be considered a “final decision.” Accordingly, appellees argue that this Court has no jurisdiction to consider these appeals.
In response, appellants contend that even if the orders denying counsel do not constitute “final decisions,” they nevertheless are appealable under the “collateral order” doctrine of Cohen v. Beneficial Industrial Loan Corp., 337 U.S. 541, 546, 69 S.Ct. 1221, 1225, 93 L.Ed. 1528 (1949). The issue in Cohen was the appealability of a district court order in a stockholder’s derivative suit, denying a defendant’s motion that the plaintiff be required to post security for costs of litigation. Although that order did not technically end the litigation on the merits, the Court held that it nevertheless was immediately appealable. The Court reasoned that an order denying security for costs would be unreviewable if review was postponed until final disposition of the merits. After disposition of the case on the merits, any right plaintiff might have to security would be lost. Thus, the Court created an exception to the final decision requirement. In Cohen the court explained that this “collateral order” exception is applicable when the district court order falls within “that small class which finally determinefs] claims of right separable from, and collateral to, rights asserted in the action, too important to be denied review and too independent of the cause itself to require that appellate consideration be deferred until the whole case is adjudicated.” Id. at 546, 69 S.Ct. at 1225.
In Caston v. Sears, Roebuck & Co., Hattiesburg, Miss., 556 F.2d 1305 (5th Cir. 1977), this Court concluded with “little hesitation” that a plaintiff who was allowed to file a Title VII suit in forma pauperis but was then denied appointed counsel could immediately appeal the denial of his application for counsel. We stated in Caston:
Obviously, the refusal to appoint an attorney is collateral to the merits of the case. The decision to deny the assistance of an appointed attorney to a layman unschooled in the law in an area as complicated as the civil rights field is truly too important to be deferred until a resolution on the merits can be had. Such an individual likely has little hope of successfully prosecuting his case to a final resolution on the merits. Thus, we hold that the denial of an application to appoint counsel pursuant to Section 706(f) of Title VII is immediately appeal-able pursuant to 28 U.S.C. § 1291.
Id. at 1308.
Appellees acknowledge the precedent established in this Circuit by Caston, and do not attempt to distinguish the present case *410on its facts.6 Instead, appellees argue that since our decision in Caston, the collateral order doctrine has been constricted and that under the later interpretations a district court order denying appointment of counsel is not appealable prior to disposition on the merits. Appellees refer to Coopers & Lybrand v. Livesay, 437 U.S. 463, 98 S.Ct. 2454, 57 L.Ed.2d 351 (1978), Firestone Tire & Rubber Co. v. Risjord, 449 U.S. 368, 101 S.Ct. 669, 66 L.Ed.2d 571 (1981), and Flanagan v. United States, - U.S. -, 104 S.Ct. 1051, 79 L.Ed.2d 288 (1984), all of which were decided by the Supreme Court subsequent to this Court’s decision in Caston.
Appellees are correct in their assertion that the Cohen doctrine has been restated with significance since our decision in Caston. One year after Caston, in Coopers & Lybrand, the Supreme Court dealt with the appealability of a district court order denying a motion to certify a case as a class action. The Court concluded that such an order was not final nor collateral and thus not appealable prior to a determination of the case on the merits. In order to qualify as collateral, the Court stated that an order must (1) “conclusively determine the disputed question”, (2) “resolve an important issue completely separate from the merits of the action”, and (3) “be effectively unreviewable on appeal from a final judgment.” Id. 437 U.S. at 468, 98 S.Ct. at 2458. The first two Coopers & Lybrand elements merely track the requirements established in Cohen. The third condition, however — that the order be effectively unreviewable on appeal from a final judgment — was not stated as part of the original Cohen test.
Applying the Coopers & Lybrand test three years later in Firestone, the Court held that an order denying a motion to disqualify counsel in a civil case was not appealable as a collateral order because the third Coopers & Lybrand element had not been met. An order denying disqualification of counsel is reviewable as part of a final judgment, and it was found not to differ significantly from other interlocutory orders reviewable only after final judgment. Id. 449 U.S. at 376, 101 S.Ct. at 674.
In its most recent pronouncement on the appealability of interlocutory orders, the Supreme Court held that the granting of pretrial motions to disqualify defense counsel in criminal prosecutions are not immediately appealable. Flanagan v. United States, - U.S. -, 104 S.Ct. 1051, 79 L.Ed.2d 288 (1984). The Court reasoned that the Sixth Amendment’s guarantee of a speedy trial required utmost strictness in the interpretation of the collateral order exception to the final judgment rule in criminal cases. Id. 104 S.Ct. at 1055.
The decision in Flanagan turned on an analysis of the second Coopers & Lybrand element. The Court held that an order granting disqualification of counsel was not an issue sufficiently separable from the merits of the action to justify immediate appeal. This was so because prejudice to a criminal defendant is not presumed upon disqualification of counsel as it would be when a criminal defendant is denied an asserted right such as appointment of counsel. The Court concluded that a criminal defendant’s rights are only violated if it can be demonstrated that a disqualification order actually resulted in prejudice to the defendant. Because actual prejudice cannot be fairly assessed until after trial, an order granting disqualification in a criminal case is not sufficiently separable from the merits of the case. Thus, the second Coopers & Lybrand element was found to be unsatisfied. Id. 104 S.Ct. at 1056.
Flanagan narrowly applies to orders granting disqualification of counsel in criminal cases. This Court has recently considered whether orders granting disqualification in civil cases would be directly appealable. We held that orders granting *411disqualification in civil cases are not appealable under the collateral order exception because such orders do not “lend themselves more readily to consideration apart from the merits of the litigation than such orders in criminal cases.” Gibbs v. Paluk, 742 F.2d 181, 186 (5th Cir.1984). The Court felt constrained by Flanagan to find that the second Coopers & Lybrand element was not satisfied because a disqualification order was of such nature that fair assessment of prejudice in the civil context, as in the criminal context, could only be made after completion of the trial. Id. at 185.7
The question presented in these appeals while somewhat analogous differs as to its critical elements from the issue of the appealability of disqualification orders. Appellees urge that the analogy is close and controlling. It is their position that in light of the recent Supreme Court decisions, Caston is no longer binding. They contend that an order denying appointment of counsel in civil rights cases does not meet the Coopers & Lybrand unreviewability test because any damage created by an erroneous order denying counsel can be remedied on appeal simply by ordering a new trial with appointed counsel. Appellees also question the separability of the appealed order from the underlying merits in view of the Supreme Court’s decision in Flanagan. They support their arguments by pointing out that other circuit courts have addressed this same issue after Coopers & Lybrand and have ruled against appealability.8 During the same period, however, other circuits have ruled that orders denying counsel in civil rights cases are appealable as collateral orders.9
The Caston decision was implicitly reaffirmed by this Court in White v. United States Pipe & Foundry Co., 646 F.2d 203 (5th Cir.1981). The Court did not address the jurisdictional question of appealability of orders denying appointment of counsel but focused instead on the merits of the district court’s grounds for denying the plaintiffs’ applications. White was decided subsequent to Coopers & Lybrand. We must, therefore, recognize that this Court decided that the result reached in Caston had not been altered by the Coopers & Lybrand redefinition of the Cohen test.10 Here we turn our attention specifically to the appealability issue, and we confirm the result in White.
*412For an interlocutory order to be appealable immediately, Coopers & Lybrand requires that the order (1) conclusively determine the disputed question, (2) resolve an important issue completely separate from the merits of the action, and (3) be effectively unreviewable on appeal from a final judgment. We conclude that all three elements are satisfied by an order denying appointment of counsel in civil rights cases and that the order is subject to immediate appeal.
The first Coopers & Lybrand element is met because the order is one that conclusively determines the question of appointment of counsel. If a defendant after denial of the motion chooses to go forward with his claim, he must do so without the assistance of appointed counsel.
The second requirement raises a closer question. Can an order denying counsel be considered separable from and collateral to the underlying merits of the litigation after Flanagan’s elaboration of the second Coopers & Lybrand element? This Court stated unequivocally in Caston that “[ojbviously, the refusal to appoint an attorney is collateral to the merits of the ease.” Id. at 1308. We do not find that Flanagan in any way alters this conclusion.
Generally speaking, no right to counsel exists in § 1983 actions. Hardwick v. Ault, 517 F.2d 295, 298 (5th Cir. 1975). However, this court has recognized that appointment of counsel should be made as authorized by 28 U.S.C. § 1915(d) where “exceptional circumstances” are present. Branch v. Cole, 686 F.2d 264, 266 (5th Cir.1982); Schack v. Florida, 391 F.2d 593 (5th Cir.), cert. denied, 392 U.S. 916, 88 S.Ct. 2080, 20 L.Ed.2d 1376 (1968). Although no comprehensive definition of “exceptional circumstances” is practical, “the existence of such circumstances will turn on the quality of two basic factors — the type and complexity of the case, and the abilities of the individual bringing it”, (footnote omitted). Branch, 686 F.2d at 266.
In Branch, a plaintiff in a post-trial appeal challenged the denial of appointment of counsel by the district court in a state prisoner’s civil rights action. This Court held that in considering whether exceptional circumstances existed, the Court could only look at facts known by the district court prior to trial. Hindsight gained by observing the litigant’s actual performance was an inappropriate consideration. Id. at 266. Branch, therefore, instructs us to review orders denying counsel in light of facts before the district court when the denial of appointment of counsel was ordered, and not in relation to what ensued at trial. This is in complete contrast to orders conveying disqualification of counsel. See Firestone and Flanagan, supra, where the evaluation is based upon prejudice at trial. The factors examined in reviewing an order denying appointment of counsel are, therefore, separable from the merits of the case. This fact meets the Caston requirement that an order to be appealable must be viewed as separate from the merits of the underlying litigation. Thus, we find that the second Coopers & Lybrand element has been satisfied.
Finally, we consider whether an order denying appointment of counsel will be effectively unreviewable on appeal from a final judgment. In Caston, this Court expressed the view that a layman unschooled in the law in the area of civil rights who had been inappropriately denied assistance of appointed counsel had little hope of successfully prosecuting his case to final resolution on the merits. Id. at 1308. This statement is no less true after Coopers & Lybrand. Indeed, there remains a great risk that a civil rights plaintiff may abandon a claim or accept an unreasonable settlement in light of his own perceived inability to proceed with the merits of his case,11 *413resulting in the loss of vital civil rights claims.
The holdings of Firestone and Gibbs dealing with disqualification of counsel do not affect our determination that orders denying appointment of counsel are effectively unreviewable because denial of appointed counsel involves different considerations. As pointed out earlier, the issue in orders involving disqualification is prejudice during trial. Disqualification orders do not result in the inability of litigants to advance through their trial and to raise possible issues of the appropriateness of the disqualification order on appeal. A litigant who can afford counsel may erroneously be denied his choice of counsel when a disqualification motion is granted, but. he is still able to proceed with other retained counsel. This is assurance that the opportunity for meaningful review will not perish. But when a litigant unable to afford counsel and unable to present his case himself is forced to proceed pro se, there is little guarantee that a civil rights action will be successfully prosecuted to appeal so that the denial of counsel may be reviewed.
We emphasize that the application of the third Coopers & Lybrand requirement is not whether a claim becomes jurisdictionally unreviewable, but whether it becomes effectively unreviewable. It is technically true, as appellees argue, that a litigant denied appointment of counsel may proceed pro se. However, it is the likelihood that a litigant will not be able effectively to prosecute his claim or to appeal that determines the reviewability of that claim rather than the theoretical existence of the right to proceed with a claim. The potential loss of a claim by a pro se civil rights litigant involves an “asserted right te legal and practical value of which would be destroyed if it were not vindicated before trial.” Firestone, 101 S.Ct. at 675 (quoting United States v. MacDonald, 435 U.S. 850, 860, 98 S.Ct. 1547, 1552, 56 L.Ed.2d 18 (1978)). Thus, we find that the third Coopers & Lybrand element is satisfied.
We conclude, therefore, that orders denying appointment of counsel to litigants who have clearly demonstrated inability to afford counsel continue to fall into the class of orders envisaged by Cohen that are directly appealable as interlocutory orders.
III. MERITS
Having concluded that an order denying appointment of counsel in a civil rights action is directly appealable, we turn to the question of whether in any of these consolidated cases such denial by the district court was an abuse of discretion. We find it necessary to remand all three cases before us because we cannot determine from the records whether the district courts exercised reasoned and well-informed discretion in denying the motions. In all three cases, the district courts made cursory findings that the cases lacked the complexity necessary to warrant appointment of counsel and that plaintiffs possessed the ability adequately to represent themselves. Although complexity of the issues and ability to represent themselves are appropriate factors in reviewing requests for appointment of counsel, we cannot review the merits without more specific findings by the district courts as to why counsel was denied in each of these cases.
REVERSED AND REMANDED.
. 28 U.S.C. § 1915(d) authorizes a trial court to appoint counsel for indigent civil litigants.
. At that time, Fifth Circuit Rule 24 was Rule 8.
. Specifically, Bolden complained that he was suffering from a rectal infection which was aggravated by an absence of prescribed treatment and medicine. Bolden also alleged negligence on the part of the nurse and physician.
. Specifically, Midkiff alleged that he was "forced to lay down on [his] stomach and hand cuffed behind [his] back with leg shackles run from [his] hands to [his] legs, and in which cut off the circulation in [his] hands and left [him] in pain for hours.” He further alleged a lack of medical care.
. We need not decide here whether the earlier document filed in the district court requesting review by this court would be the substantial equivalent of a timely notice of appeal.
. We take note that Caston involved an action filed under Title VII, in contrast with the three cases consolidated here, all of which were filed pursuant to 42 U.S.C. § 1983. For purposes of the issue of appealability, however, we find no significant legal distinction between a Title VII case and a § 1983 case.
. Two other circuits have held to the contrary, see Interco Systems, Inc. v. Omni Corporate Services, Inc., 733 F.2d 253 (2nd Cir.1984), Koller v. Richardson-Merrell, Inc., 737 F.2d 1038 (D.C.Cir. 1984).
. The Second Circuit had held against appealability in Miller v. Pleasure, 425 F.2d 1205 (2nd Cir.), cert. denied, 400 U.S. 880, 91 S.Ct. 123, 27 L.Ed.2d 117 (1970). After Coopers & Lybrand additional circuits have held that an order denying appointment of counsel is not immediately appealable because such an order is not effectively unreviewable. See Appleby v. Meachum, 696 F.2d 145 (1st Cir.1983); Randle v. Victor Welding Supply Co., 664 F.2d 1064 (7th Cir. 1981) (overruling a prior decision in Jones v. WFYR Radio/RKO General, 626 F.2d 576 (7th Cir.1980)); Cotner v. Mason, 657 F.2d 1390 (10th Cir.1981). In a post-Flanagan case, the Third Circuit held in Smith-Bey v. Petsock, 741 F.2d 22 (3d Cir.1984), that orders denying appointment of counsel were not subject to immediate appeal because such orders were not sufficiently separable from the underlying merits, overruling its previous holding in Ray v. Robinson, 640 F.2d 474 (3d Cir.1981).
. The Eighth Circuit decided in three pre-Flanagan cases that orders denying appointment of counsel in civil rights cases were immediately appealable. Slaughter v. City of Maplewood, 731 F.2d 587 (8th Cir.1984), Hudak v. Curators of University of Missouri, 586 F.2d 105 (8th Cir.1978), cert. denied, 440 U.S. 985, 99 S.Ct. 1799, 60 L.Ed.2d 247 (1979) (denial of appointment of counsel in an employment discrimination suit was immediately appealable under Title VII and 42 U.S.C. 1981 and 1982), and Peterson v. Nadler, 452 F.2d 754 (8th Cir.1971) (denial of appointment of counsel directly appealable in an action for a fraudulent conversion of an indigent’s property by his former attorney). In Henry v. City of Detroit Manpower, 739 F.2d 1109 (6th Cir.1984), the Sixth Circuit held, post-Flanagan, that interlocutory orders denying appointment of counsel could be immediately appealed. The Ninth Circuit reached a similar conclusion in a Title VII case in Bradshaw v. Zoological Society, 662 F.2d 1301 (9th Cir.1981).
. The Court in White noted that the district court explained to the plaintiffs in that case that its denial of their applications for counsel could be immediately appealed. Id. at 205 note 4.
. We note, as did the Ninth Circuit in Bradshaw v. Zoological Society of San Diego, 662 F.2d 1301, 1310 n. 22 (9th Cir.1981), that abandoning a claim in a civil rights case because of a denial of appointed counsel must be distinguished from abandoning a claim because of failure to certify a class, which was the issue in Coopers & Lybrand, 98 S.Ct. at 2458-62. In Coopers & Lybrand, the Supreme Court discussed the so called "death knell” doctrine as a *413possible justification of appealability of a class certification claim. The Court held that the doctrine did not justify appellate jurisdiction for interlocutory orders denying class certification. Under the "death knell” doctrine, some courts have allowed immediate appeal of orders in certain cases on the theory that denial of direct appeal would effectively preclude review of any of the issues in those cases, not just of the collateral issues from which the appeals were taken. Gillespie v. United States Steel Corporation, 379 U.S. 148, 152-55, 85 S.Ct. 308, 311-12, 13 L.Ed.2d 199 (1964); 15 Wright, Miller & Cooper, Federal Practice and Procedure § 3912 (1976). As this Court noted, “neither the language nor holding of [Coopers & Lybrand ], or the views of the commentators as to its meaning,” support an argument that the decision overruled the death knell doctrine in contexts other than denial of class certification. McKnight v. Blanchard, 667 F.2d 477, 479 (5th Cir.1982).
