¶ 1 The primary question before us is whether the district court’s decision — to incorporate an exhibit by reference into Lorita J. Sneed’s [Sneed or deceased] earlier-admit*1114ted last will and testament — is against the clear weight of the evidence. Also at issue is whether Donna Kay Hall [Hall, contestant or appellant] is entitled to a new hearing to decide whether Michael Jestes1 [Jestes, proponent or personal representative] unduly influenced Sneed in the making of the incorporated exhibit.
I
PROCEDURAL FACTS AND HISTORY
¶ 2 On August 22,1990 Lorita Sneed executed a last will and testament. She died in March 1992. Under her will’s terms all of her property, both real and personal, was devised to Michael Jestes, as trustee, with instructions that he distribute the same under the terms of Exhibit “A” to the will.
¶ 3 Athough the exhibit attached to the will was dated August 20, 1990, there is evidence that its “trust” provisions were originally drafted on August 17, 1990. The exhibit purports to reflect the testatrix’s “living will wishes.” Jestes testified that he acted as Sneed’s scrivener in the exhibit’s preparation and did nothing more than record her decisions about how her assets were to be distributed.2
¶ 4 The testatrix died without issue. Under the dispositive provisions [as found in Exhibit “A”] of the Sneed will her estate is devised to (a) the heirs of her deceased brother [Kenneth Hall], i.e., the contestant and her two children, (b) the children of her deceased step-brother [Marlin Marsh], (c) Jestes and his sister and (d) various other friends and her church. The contestant and her children were the principal beneficiaries under the decedent’s will, although the devises to Marlin Marsh’s children and Jestes and his sister were each close in amount to the quantum given the contestant and her children.
¶ 5 The decedent’s will was prepared by her lawyer of many years and was executed in his office. Athough Jestes was present when the will was executed, he did not serve as one of its witnesses. Since Exhibit “A” to the will contains the dispositive provisions for Sneed’s estate and it is specifically referenced in the will, her lawyer obviously reviewed the exhibit’s terms when he drafted the document. Nonetheless, the record does not reflect any discussions between the lawyer and the testatrix about the will or its exhibit’s provisions except on the day of the will’s execution when the testatrix acknowledged before its witnesses that the document represented her dispositive wishes.3
¶ 6 On October 19,1993 Jestes petitioned the district court to probate Sneed’s will. Hall objected to its admission urging (1) that her aunt was of diminished mental capacity and suffered from insane delusions and (2) that Sneed’s free agency had been overborne by Jestes’ undue influence. In the summer of 1994 the trial court, sitting in probate, conducted a hearing on Sneed’s testamentary capacity and the issue of undue influence. This hearing was held before the exhibit in issue was bifurcated from the will. During this proceeding the contestant examined Jestes about (a) his relationship with Sneed, (b) his role in the preparation of Exhibit “A”, and (c) the execution of the decedent’s last will and testament. It was also at this time that Jestes’ counsel requested that Exhibit “A” be severed from the will and transferred to a division of the district court with the authority to determine if its provisions satisfied the requirements for the establishment of a valid inter vivos trust. In its August 30, 1994 order the trial court (sitting in probate) found that Exhibit “A” was “not being offered as either a testamentary disposition [or] as a residuary disposition under the residuary clause” of Sneed’s will. Aso, it found that Exhibit “A” was not being offered as a testamentary trust under the will’s terms and that it [the court sitting in probate] did not have the remedial capacity to ascertain the instrument’s validity as an inter vivos trust. At *1115the conclusion of the July 1994 hearing the latter issue was severed from the probate proceedings and transferred to the Chief Judge, Civil Division, Oklahoma County District Court. The district court-in an exercise of its remedial powers — concluded that the exhibit’s provisions did not meet the statutory requirements necessary to establish an inter vivos trust.
¶ 7 After the district court ruled that the exhibits provisions failed to create an inter vivos trust, the will’s proponent moved to incorporate by reference the document’s terms into Sneed’s will. By its August 11, 1995 order the court allowed the requested incorporation and denied the contestant’s motion for a hearing on the issue of .the proponent’s undue influence in the exhibit’s preparation. It is from this latter order that Hall brings her appeal. The Court of Civil Appeals upheld the district court’s decision. The appellant then sought certiorari which was granted.
II
THE STANDARD OF REVIEW
¶ 8 Probate proceedings are of equitable cognizance.4 While the Court will examine the whole record and weigh the evidence, the trial court’s findings will not be disturbed on review unless they are clearly against the weight of the evidence or some governing principle of law.5 We are mindful that when a will is offered for probate, the factum of the will — i.e., (a) whether the will has been executed with the requisite statutory formalities, (b) whether the testatrix was competent to make a will at the time it was made, and (c) whether it was the product of undue influence, fraud or duress — becomes the singular concern of the court.6 The emphasis of this entire process is to discern and effectuate the decedent’s dispositive intentions.7
Ill
SNEED WAS POSSESSED OF TESTAMENTARY CAPACITY
¶ 9 Testamentary capacity exists when a person possesses, in a general way, the ability to appreciate the character and extent of the devised property, understands the nature of the relationship between themselves and the objects of their bounty and apprehends the nature and effect of the testamentary act.8 Whether one possesses testamentary capacity is a question of fact. When a person contests a testator’s soundness of mind, the burden of persuasion associated with the issue rests upon them.9 When a court ascertains a decedent’s testamentary capacity, it is appropriate for it to consider evidence of the testator’s mental capacity, appearance, conduct, habits and conversation both before and after the will is executed — if these factors are relevant to his/hér mental condition at the time the will was executed.10
¶ 10 From the record it is apparent that until the very end of Sneed’s life she was a self-reliant-person with an independent will. She lived alone, drove her own car until the time of her death, mowed her own lawn, managed rental properties which she owned, and on occasions — contemporaneous to the execution of her will — managed a dentist’s business office while he was out of town. The conveyances,11 which Sneed made after executing her will, amply demonstrate that *1116she understood the character of her property and further that she understood the intended effect of her testamentary acts — even though the district court later determined that the provisions of Exhibit “A” were not legally sufficient to create an inter vivos trust. No evidence indicates any desire on the testatrix’s part to change, alter or revoke the will during the almost two years between its execution and her demise.12 From review of the record it cannot be said that the district court’s decision that Lorita Sneed was possessed of testamentary capacity is clearly against the weight of the evidence.
IV
THE DOCTRINE OF CLAIM PRECLUSION (RES JUDICATA) CANNOT BE BASED ON THE DISTRICT COURT’S JULY 6, 1994 ORDER SINCE THAT ORDER WAS NOT FINAL
¶ 11 Sneed’s last will and testament, when proffered to the district court for admission, consisted of two pages plus Exhibit “A”. When it was suggested by the will’s proponent that the district court, sitting in probate, did not have “jurisdiction” to determine whether the terms of Exhibit “A” actually created an inter vivos trust, the district court by its July 6,1994 order bifurcated the exhibit from the will — concluding that Exhibit “A” was not then being “offered” as a testamentary disposition, a residuary disposition or as Sneed’s will. In this same order the district court judge, in reference to Exhibit “A”, stated, “[A]ny rulings thereon will be reserved pending a[n] adjudication by the district bench as to its validity and operational effect of the instrument itself....”13 The contestant asserts that because Jestes sought severance of the critical exhibit from the probate court’s consideration, he was barred by the doctrine of claim preclusion (res judi-cata ) from later seeking incorporation of the exhibit’s provisions into the Sneed will.
¶ 12 The July 6, 1994 order’s language makes clear that the district court, sitting in probate, intended to reserve consideration of what effect, if any, should be given Exhibit “A” in the event it should be determined that its provisions did not create an inter vivos trust. This order — insofar as it concerns Exhibit “A” — is interlocutory and not final. By its July 6, 1994 ruling the district court merely found that the proponent was not offering the exhibit as a testamentary disposition. The issue of what legal effect, if any, would be extended to the exhibit’s terms was reserved until after the district court had determined if the exhibit’s provisions created an inter vivos trust.
¶ 13 The doctrine of claim preclusion operates to bar relitigation by the parties or their privies of issues which either were or could have been litigated in a prior action which resulted in a final judgment on the merits.14 Because there had not been a final decree entered in Sneed’s probate, there was no final judgment.15 Under these circumstances the doctrine of claim preclusion is not available to the contestant to prevent the court’s incorporation of Exhibit “A” into Sneed’s wül.
¶ 14 The criteria for incorporation of an extraneous instrument into a wül by reference are: (1) the document must be in existence when the wül is executed, (2) the will’s text must reasonably identify the instrument, and (3) the reference must show the testatrix’s intention to incorporate the document into her wül or “at least [the] intention that the instrument should operate with [the] wül in disposing of property left *1117... at death.”-16 Exhibit “A” predated Sneed’s- will, was specifically referenced and attached to the will, and contains Sneed’s instructions for disposition of her estate. The exhibit to Sneed’s will clearly meets all of the delineated criteria for incorporation by reference. The district court’s order allowing the incorporation of the exhibit’s terms into Sneed’s will is sustained because all of the law’s criteria for incorporation are satisfied and the probate court was not precluded from doing so by the doctrine of res judicata.
V
THE DISTRICT COURT’S REFUSAL TO CONDUCT A NEW HEARING ABOUT WHETHER SNEED’S WILL (WITH THE INCORPORATED EXHIBIT “A”) WAS THE PRODUCT OF UNDUE INFLUENCE DID NOT DENY THE CONTESTANT DUE PROCESS
¶ 15 Initially it must be said that a district court judge who is assigned a case is deemed to have read all pleadings and paperwork in the file unless the contrary is affirmatively demonstrated by the record. The contestant would have us assume that the Honorable Carol Hubbard, Judge, District Court, Oklahoma County, did not familiarize herself with all of the materials in the court’s file — including the transcripts of the earlier hearing on the issues of (a) Sneed’s testamentary capacity and (b) undue influence, filed with the court on June 26, 1995— when she denied the contestant another hearing on undue influence.17 This we will not do sans affirmative proof.18
¶ 16 Minimum standards of due process require that the district court, sitting in probate, afford the contestant an opportunity to be heard on the issues of Sneed’s testamentary capacity and undue influence.19 During the 1994 hearing culminating in the district court’s July 6, 1994 order admitting the will to probate, the contestant examined the proponent about the preparation, execution and contents of Exhibit “A”- — even though the court later concluded that the exhibit should be bifurcated from the will. This testimony was part of the court’s file in this matter when Judge Hubbard permitted the incorporation of the exhibit’s terms into Sneed’s will. Hér ruling is impliedly based on consideration of this evidence and an implied. corollary finding that the exhibit was not the product of undue influence. The contestant has been given the meaningful opportunity which due process requires.
VI
THE DISTRICT COURT’S INCORPORATION OF EXHIBIT “A” INTO SNEED’S WILL IS NOT CLEARLY CONTRARY TO THE WEIGHT OF THE EVIDENCE
¶ 17 ■ Undue influence is that degree of influence which destroys the testatrix’s free agency and must occur at the time when the will is executed to be condemnable.20 For influence to be wrongful, it must be used directly to procure the will and rise to a level of coercion which in effect substitutes another’s will for that of the testatrix’s. The existence of a confidential relationship between the testatrix and a family member or friend is a circumstance, which will not defeat a will unless it is shown-to affect the substance of the decedent’s testamentary act.21
*1118¶ 18 The contestant would have the district court, sitting in probate, presume that Sneed’s will was the product of Jestes’ undue influence. Hall urges that she should have been given the benefit of a rebuttable presumption of undue influence22 because (1) the devise to Jestes and his sister was unnatural since they were not related by blood to the decedent, (2) Jestes was in a confidential relationship with Sneed until the time of her death,23 and finally (3) Sneed did not receive independent advice from her attorney regarding the provisions of Exhibit “A”.
¶ 19 The foundational facts upon which a court could predicate a finding that the presumption of undue influence is applicable are not demonstrated by the record in this matter. Sneed’s bequest to Jestes and his sister is not unnatural as that term is used in assaying the availability of the presumption of undue influence. Nor does her testamentary scheme result in strangers receiving all of her property.24 While she did not give her entire estate to her blood relatives — i.e., the contestant and her children — she did not disinherit them since they are in fact her principal heirs.25 Simply because Jestes and his sister were not the decedent’s blood relatives, does not remove them from the class of persons towards whom the testatrix could be naturally inclined to convey her estate.26 Jestes enjoyed a kindred relationship — though not of blood — with his enately-related great aunt for over forty years. Although Sneed and Jestes’ great uncle were divorced at the time of her death, there is nothing in the record to evidence that Jestes and his great aunt enjoyed anything but a healthy, cordial and supportive relationship until her death. While the record evinces that the will’s proponent and the decedent dined on a regular basis, i.e., twice a month, and did on occasion pray together, this in and of itself is neither wrongful nor sufficient to create a presumption of undue influence.27 Nor is the fact that Jestes served as the scrivener for Exhibit “A”, without more, sufficient to create the sought presumption.28 Finally, Jestes’ presence in the room when Sneed executed her will does not constitute, of itself, “active” participation in either the preparation or execution of the testamentary instrument.29 Power, motive, and opportunity to exercise wrongful influence, standing alone, do not raise a presumption that undue influence was exerted in a will’s procurement.30 This is especially true where, as here, the uncontro-verted evidence is that the testatrix — at a date later than that of the supposedly tainted *1119exhibit — sought the assistance of independent counsel to prepare her will, a will which the court found was not the product of undue influence. The existence of undue influence is a question of fact and the district court’s finding on this issue is not clearly contrary to the weight of the evidence.
VII
THE APPELLEE’S MOTION FOR AN APPEAL-RELATED COUNSEL-FEE AWARD IS DENIED
¶20 The appellee seeks an appeal-related counsel fee award under the terms of Okla.Sup.Ct.R. 1.14.31 Such an award is appropriate only when the appeal is one having no reasonable legal or factual basis to support it.32 All doubts whether the appeal is frivolous should be resolved in favor of the appellant.33 Because it cannot be said that Hall’s appeal is frivolous, the appellee’s motion for appeal-related attorney fees is denied.
VII
SUMMARY
¶21 Because each of the law’s requirements for incorporation of Exhibit “A” by reference into Sneed’s will are fully satisfied, the district court’s decision to do the same is legally correct. Our standard of review requires that we further assay the validity of the district court’s probate order to determine that it is not clearly contrary to the weight of the evidence.
¶22 Based upon an assessment of the facts detailed in the record there is nothing in Sneed’s will which is inconsistent with her obligations or affections during the latter part of her life. She did not disinherit her blood relatives, i.e., the contestant and her children who are the principal beneficiaries under her will’s terms. The other heirs are either her kindred, friends or her church.
¶ 23 In its establishment of the will’s fac-tum the district court determined that Sneed possessed the requisite mental capacity to execute her will and that her free agency was not overborne by the .will’s proponent. Almost two years intervened between the will’s execution and Sneed’s death. During this time Sneed not only conducted her own business affairs in an independent fashion but she also managed them in a manner consistent with and supportive of the dispositive intentions reflected in her will. On this record the district court’s decision to admit Sneed’s will to probate with the terms of Exhibit “A” incorporated into it is clearly not contrary to the weight of the evidence. On certiorari previously granted,
THE COURT OF CIVIL APPEALS’ OPINION IS VACATED AND THE DISTRICT COURT’S PROBATE ORDER IS AFFIRMED; APPELLEE’S MOTION FOR APPEAL-RELATED ATTORNEY FEES IS DENIED.
