Appellant contends that the lower court erred in denying her petition for class certification. We agree and, accordingly, reverse the order of the court below and certify the class.
Appellant is the primary beneficiary of two life insurance policies purchased from appellee by her late husband. The policies, issued in 1964 and 1966, contained identical “family-income benefit riders” providing that she would receive fifty dollars per month under each during the payment period. Each policy defined the payment period as “65 years less years of issue age.” Appellant’s husband died in 1969 at the age of 51. Appellant commenced this action seeking damages and declaratory relief on March 3, 1977, alleging, individually and as representative of a class of similarly situated beneficiaries, that the payment period should be determined by subtracting from 65 years the insured’s age at the times the policies were issued. According to her construction, her payment periods would be nineteen and seventeen years, respectively. Appellee contends, however, that the period should be determined by subtracting from 65 years the insured’s age at the time of death, so that appellant’s payment periods would both be fourteen years. Following the denial of appellee’s preliminary objections, the court below established a class action discovery timetable, held a class certification hearing, and subsequently denied appellant’s motion to certify the class. This appeal followed. 1

Appellant contends that the lower court abused its discretion in holding that she had failed to meet her burden of proving each of the requirements and criteria for class certification. Pa.R.Civ.P. 1702, 1708, 1709. We agree. A lower court’s decision concerning class certification is a mixed finding of law and fact entitled to “appropriate deference” upon appeal.
Bell v. Beneficial Consumer Discount Co.,
*128 II.
It is beyond peradventure that the burden of proof in a class certification proceeding is upon the party seeking certification.
Klemow
v.
Time, Inc., supra; Scott v. Adal Corp.,
276 Pa.Superior Ct. 459,
Once the class action allegations are well-pleaded, as was conceded here, the class proponent at the class
*130
certification hearing must present evidence of the underlying facts from which the court can conclude that the five class certification requirements are met.
See Ablin, Inc. v. Bell Telephone Co. of Pennsylvania, supra; Zeidman v. J. Ray McDermott & Co., supra. Cf.
Pa.R.Civ.P. 2329 (petition to intervene) (also requires hearing, intervenor’s burden met upon prima facie showing). Because the requirements for class certification are closely interrelated and overlapping, the class proponent need not prove separate facts supporting each; rather, her burden is to sufficiently establish those underlying facts from which the court can make the necessary conclusions and discretionary determinations.
See, e.g., Ablin, Inc. v. Bell Telephone Co. of Pennsylvania, supra
*131 III.
Rule 1702 of the Pennsylvania Rules of Civil Procedure states the five prerequisites to class certification:
One or more members of a class may sue or be sued as representative parties on behalf of all members in a class action only if
(1) the class is so numerous that joinder of all members is impracticable;
(2) there are questions of law or fact common to the class;
(3) the claims or defenses of the representative parties are typical of the claims or defenses of the class;
(4) the representative parties will fairly and adequately assert and protect the interests of the class under the criteria set forth in Rule 1709; and
(5) a class action provides a fair and efficient method for adjudication of the controversy under the criteria set forth in Rule 1708.
1. Numerosity
Appellant purports to represent a class of beneficiaries of “family-income benefit” riders issued by appellee. To be eligible for certification, she must establish that the class is “so numerous that joinder of all members is impracticable.” Pa.R.Civ.P. 1702(1). Whether the number is so large as to make joinder impracticable is dependent “not upon any arbitrary limit, but rather upon the circumstances surrounding [each] case.” 3B J. Moore,
Federal Practice and Procedure,
§ 23.05 (19). In determining numerosity, the court should examine “whether the number of potential individual plaintiffs would pose a grave imposition on the resources of the court and an unnecessary drain on the energies and resources of the litigants.”
Temple University of the Commonwealth System of Higher Education v. Pennsylvania Department of Public Welfare,
30 Pa.Commonwealth Ct. 595, 603,
2. Common Questions of Law or Fact (Commonality)
Appellant must establish that her claim presents “questions of law or fact common to the class.” Pa.R.Civ.P.
*133
1702(2). The existence of individual questions essential to a class member’s recovery is not necessarily fatal to the class, and is contemplated by the rules.
See
Pa.R.Civ.P. 1708(a)(1) (whether common questions “predominate” over individual ones), 1710 (power to limit issues);
Klemow v. Time, Inc., supra
3. Typicality
Appellant must show that her “claims or defenses ... are typical of the claims or defenses of the class.” Pa.R.Civ.P. 1702(3). The .typicality requirement is closely akin to the requirements of commonality and the adequacy of representation.
Ablin, Inc. v. Bell Telephone Co. of Pennsylvania, supra
291 Pa.Superior Ct. at 40,
4. Adequacy of Representation
For the class to be certified, the court must conclude that appellant “will fairly and adequately assert and protect the interests of the absent class members.” Pa.R.Civ.P. 1702(4). To make this determination the court must consider: (1) whether the attorney for the representative party will adequately protect the class’s interests; (2) whether the representative parties have a conflict of interest in maintaining the action; (3) whether the representative parties “have or can acquire” adequate financial resources; and (4) “other matters.” Pa.R.Civ.P. 1709.
Preliminarily, “[a] litigant must be a member of the class which he or she seeks to represent at the time the class is certified by the . . . court” in order to ensure due process to the absent class members and to satisfy requirements of standing.
Sosna v. Iowa,
a. Attorney’s Adequacy
Generally, “[u]ntil the contrary is demonstrated, courts will assume that members of the bar are skilled in their profession.”
Dolgow v. Anderson,
b. No Conflict of Interest
The lower court suggested many possible conflicts of interest or hidden collusive circumstances (such as family or financial ties to appellee) that appellant might have attempted to disprove. Because of the difficulty of proving a negative, courts have generally presumed that no conflict of interest exists unless otherwise demonstrated, and have re
*137
lied upon the adversary system and the court’s supervisory powers to expose and mitigate any conflict.
Wetzel v. Liberty Mutual Insurance Co.,
c. Adequate Financial Resources
“[T]o assure that the interests of the class will not be harmed” the court must consider whether the representative parties “have or can acquire adequate financial resources” to prepare the litigation and carry it to completion. Pa.R. Civ.P. 1709(3); Explanatory Note to Pa.R.Civ.P. 1709. Appellant’s counsel submitted an affidavit that it would advance all costs of the litigation, but that appellant would remain ultimately liable for them. There was no dispute as to counsel’s ability to advance the needed funds. The lower court determined that appellant would be unable to repay counsel if unsuccessful. Initial funding by the class representative’s attorney is not uncommon in class suits,
see, eg., Sanderson v. Winner,
d. Other Matters
The lower court held that appellant’s lack of personal knowledge about the lawsuit, as indicated by her apparent mistaken belief that the action included claims based on a salesman’s oral representations, rendered her unable to adequately supervise or assist class counsel, and thus an inadequate class representative. “[A] class representative need not be the best of all possible representatives
*140
but rather one that will pursue a resolution of the controversy with the requisite vigor and in the interest of the class.”
Piel v. National Semiconductor Corp.,
supra at 366. Courts should not impose unrealistically high burdens of knowledge or ability to supervise counsel, for to do so would render the class action an impotent tool or deny it to those most in need.
See, e.g., Surowitz v. Hilton Hotels Corp.,
5. Fairness and Efficiency of Class Action
The final general requirement for class certification is that a class action provide “a fair and efficient method for
*141
adjudication of the controversy.” Pa.R.Civ.P. 1702(5). Several criteria must guide the court in this determination. Pa.R.Civ.P. 1708. They are not exclusive and their importance may vary according to the circumstances.
Id.; Katz v. Carte Blanche Corp.,
a. Common Questions Predominate
“[WJhether common questions of law or fact predominate over individual questions,” Pa.R.Civ.P. 1708(a)(1), is closely akin to the requirement that sufficient common questions exist to support the class action, Pa.R.Civ.P. 1702(2). Individual questions, even those essential to recovery, are not necessarily fatal to the class action.
See, e.g., Cross
v.
National Trust Life Insurance Co.,
b. Manageable Controversy
In determining the fairness and efficiency of a class action the court must consider “the size of the class and the difficulties likely to be encountered in the management of the action as a class action.” Pa.R.Civ.P. 1708(a)(2). Problems of administration alone, however, ordinarily should not justify the denial of an otherwise appropriate class action, for to do so would contradict the policies underlying this device.
Yaffe v. Powers,
*143 c. Risks of Inconsistent Adjudications
The court must also consider the risks of inconsistent adjudication from both the plaintiff’s and defendant’s viewpoints. It must consider whether separate actions (1) would “confront the party opposing the class with incompatible standards of conduct,” Pa.R.Civ.P. 1708(a)(3)(i), or (2) would, “as a practical matter,” be dispositive of the interests of absent potential class members or otherwise “substantially impair or impede their ability to protect their interests,” Pa.R.Civ.P. 1708(a)(3)(ii). Finding such risks is not essential to certifying the class, but “if they exist, they will be forceful arguments in support of the approval of the class action.” Explanatory Note to Pa.R.Civ.P. 1708. The court below held that the principle of
stare decisis
and proper application of fundamental contract principles would eliminate any risks of inconsistent adjudications. Such reasoning ignores the rule’s exhortation to address this consideration “as a practical matter.” Pa.R.Civ.P. 1708(a)(3)(ii). Courts may, and often do, differ in resolving similar questions presenting issues of law or fact. The precedential effect of a decision, even if incorrect, may have a chilling effect on the assertion of similar claims, and, combined with the expiring of statutes of limitation, may often “substantially impair or impede” potential litigants’ ability to protect their interests.
Id.
Moreover, as with the related criteria concerning the complexity and expenses of litigation, Pa.R. Civ.P. 1708(a)(6), the court may consider the parties’ circumstances and respective ability to pursue separate actions.
Cf. Scott v. Adal Corp., supra; Hohmann v. Packard Instrument Co.,
d. Complexity of Issues or Expenses Deterring Separate Actions
The court must consider whether the “complexity of issues” or “expenses of litigation” are so burdensome that, upon comparison, the amounts of individual class members’ claims “are insufficient to support separate actions.” Pa.R. Civ.P. 1708(a)(6). Appellant’s claim is for approximately $4,000. Resolving the underlying contract interpretation issue will not require expert witnesses or extensive discovery. From the nature of the question in dispute, it can be inferred that the amounts of class members’ claims will vary greatly. This criterion, like the others, must be considered realistically in light of the circumstances. To prevail on individual claims, class members would be forced to retain separate counsel and pay court costs, thus duplicating expenses. Moreover, small, but meritorious, claims may go unlitigated. Further, there is a possibility that appellee would simply settle appellant’s individual claims, preventing an adverse decision on the merits, and thereby precluding effective relief to many.
See Deposit Guaranty National Bank v. Roper,
e. De Minimis Individual Recovery
The court must consider “whether it is likely that the amount which may be recovered by the individual class members will be so small in relation to the expenses and effort of administering the action as not to justify a class action.” Pa.R.Civ.P. 1708(a)(7). The nature of the claim is such that, should the class prevail, its members would generally receive more than trivial sums. Moreover, it is unlikely that the costs of requisite notice to class members would be disproportionate to the size of their claims. Consequently, this action may yield sufficient benefits to the class members to justify its use of judicial resources.
f. Opponent’s Conduct Generally Applicable
Because appellant seeks declaratory relief, the court must also consider “whether the party opposing the class has acted or refused to act on grounds generally applicable to the class, thereby making final equitable or declaratory *146 relief appropriate with respect to the class.” Pa.R.Civ.P. 1708(b)(2). Appellee concedes that it applies a similar interpretation to all eight insurance riders in question, thus satisfying this criterion.
IY.
For the foregoing reasons we are satisfied that this case is appropriate for disposition as a class action and, accordingly, we reverse the court below and enter the following order:
1. Appellant, MARGARET E. JANICIK, is hereby certified as the representative of a class defined as followed: All persons who after March 3, 1971 and before the entry of final judgment in this case received, were entitled to receive, or become entitled to receive benefits from appellee, PRUDENTIAL INSURANCE COMPANY, pursuant to family-income benefit provisions on forms B 132, B 135, G 132 P, E 132 P, G 135 P, G 139 P, G 171 P, and E 183 P, or any substantially similar form, or policy schedule providing for benefits to be paid for a period computed as “65 [or some other number of] years less years of issue age.”
2. Exclusion and Inclusion.
(a) All Pennsylvania residents who are members of the class defined above shall be included in this action unless such member files of record a written election to be excluded from the class.
(b) All members of the class defined above who are not Pennsylvania residents shall be excluded from this action unless such member files of record a written election to be included in the class. 15
*147 3. The court below shall approve the notice to be sent to each category of members defined in paragraphs 1 and 2 above, Pa.R.Civ.P. 1712, and shall specify the date for filing the appropriate election to be included in or excluded from the class.
4. This Order is without prejudice to the lower court’s power to alter, amend, or supplement it as may be appropriate under the circumstances from time to time, Pa.R.Civ.P. 1710, 1713.
5. The matter is remanded for proceedings consistent with this Opinion.
Notes
. An order denying class certification is a final and appealable order.
Bell v. Beneficial Consumer Discount Co.,
. Under Pa.R.Civ.P. 1710, 1711, the lower court is required to set forth findings of fact, conclusions of law, and appropriate discussion in a written opinion when certifying, refusing to certify, or revoking a class certification. The better practice, to facilitate management of the action and to ensure meaningful appellate review, is to set forth each of the elements separately as per the form for adjudication in equity under Pa.R.Civ.P. 1517(a). Explanatory Note to Pa.R.Civ.P. 1710.
. Federal precedent is instructive in construing Pennsylvania’s class action rules.
See McMonagle v. Allstate Insurance Co.,
. Appellant’s not accepting appellee’s offer that she could manually search its flies under a protective order does' not prejudice her petition for class certification, because she submitted sufficient other evidence of numerosity.
But cf. Reichlin v. Wolfson,
. If, however, the challenged conduct affects the potential class members in such divergent ways, aggrieving some, benefitting others, that their interests become antagonistic to each other, commonality may not exist.
Samuels v. Smock,
54 Pa.Commonwealth Ct. 597,
. Typicality might not be satisfied when the relief sought will benefit some proposed class members and harm others,
Samuels v. Smock, supra; William Goldman Theaters, Inc. v. Paramount Film Distributing Corp., supra,
or when the class representative has or is pursuing some other interest divergent from or adverse to the interests of the absent class members.
Penn Galvanizing Co. v. Philadelphia, supra
(representative’s interest adverse to absent class members);
Samuels v. Smock, supra
(representative’s eligibility for the subject retirement benefits being separately litigated and his interest in pension fund not shown to be substantially similar to the absent class members’);
Puharich v. Borders Electronics Co.,
CCH Fed. Sec. p. 92, 160 (class action on behalf of shareholders clearly of secondary importance to representatives’ unique derivative claims).
But cf. Marshall v. Holiday Magic, Inc.,
. Courts may, however, entertain a class action even if the representative’s claim is rendered moot by the passage of time or an attempt
*136
ed separate settlement,
see McMonagle v. Allstate Insurance Co., supra,
. Moreover, several courts have taken notice of appellant’s counsel’s adequacy to litigate class actions.
See, e.g., Stavrides v. Mellon Bank, N.A.,
. Courts have repeatedly held it a disqualifying conflict of interest for the representative party to serve in a dual capacity as both class representative and class counsel,
Murphy v. Harleysville Mutual Insurance Co.,
282 Pa.Superior Ct. 244,
. Some courts have held maintenance of class suits by legal aid societies or legal services organizations to be less strictly limited by the Code of Professional Responsibility than would be such funding by private attorneys.
Aguirre v. Bustos,
. “It has been said that the entire ‘historic mission’ of the class action is to take ‘care of the smaller guy.’ Frankel, Amended Rule 23 from a Judge’s Point of View, 32 Antitrust L.J. 295, 299 (1966).”
*139
McMonagle v. Allstate Insurance Co., supra,
227 Pa.Superior Ct. at 213 n. 12,
. We are cognizant that an attorney’s advancing litigation costs may raise different inferences about adequacy of representation when the representative party is able but unwilling to bear litigation costs. See, e.g., Charal v. Andes, supra; Chevalier v. Baird Savings Ass’n, supra.
. Thus Pennsylvania courts need not speculate whether a “test case” might be a better method of resolving a given dispute. Cf., Katz v. Carte Blanche Corp., supra (considering whether test case would be superior to class action). However, the existence of a readily available, inexpensive, and efficient alternative method of obtaining the relief may be a factor militating against a class action. Samuels v. Smock, supra.
. In determining fairness and efficiency, the court must consider “the extent and nature of any litigation already commenced by or against members of the class involving any of the same issues.” Pa.R.Civ.P. 1708(a)(4). This is a criterion of limited relevance, applicable primarily to cases in which many similar claims are filed, as after a mass tort, or in which competing class actions have been initiated. Explanatory Note to Pa.R.Civ.P. 1708. At the time of the certification hearing, no other actions had been filed concerning this question. The court must also consider “whether the particular forum is appropriate for the litigation of the claims of the entire class.” Pa.R.Civ.P. 1708(a)(5). Our Supreme Court has held that a common pleas court may exercise jurisdiction over absent class members who are Pennsylvania residents, as well as those non-residents who submit themselves to its jurisdiction.
Klemow v. Time, Inc., supra
. Appellee asserts in a reargument petition that the parties had stipulated by exchange of letters that appellant sought only to represent a class of Pennsylvania residents. The letters do not appear in the record before us. Limiting this class to Pennsylvania residents would not change our analysis or decision regarding numerosity or the propriety of this class action. If appellant seeks only to represent Pennsylvania residents, or if the parties have indeed stipulated, the lower court should be informed and requested to modify this order accordingly. See Order ¶ 4, infra.
