¶ 1 The issue presented is whether the trial court erred in admitting the contested will to probate. We find that it did.
FACTS
¶ 2 On June 15, 1982, Shirley Joyce Speers (testatrix) signed a “Last Will and Testament” (will/instrument). It named her husband, Ralph Speers (husband) as her executor and Doyle Wesley Fincher as her alternate executor. It also gave her daughter, Sherry Arlene Ross, her household furnishings and appliances, and her son, Daniel Eugene Speers, her livestock. Her husband was named the beneficiary of the rest of the estate, provided he paid the estate’s expenses. If he failed to do so, his share was devised in equal parts to James Nelson Fincher and Jonathan Clyde Fincher, the testatrix’s grandsons. The will expressly omitted LeeAnn Fincher, the testatrix’s daughter. It was signed by Sadie B. Walton (Walton) and Walter Durbin (Durbin) as witnesses and notarized by Vicky Thomas (notary), but it was not stamped with a notary seal. The testatrix died on April 20, 1997, and the instrument was not probated at the time of her death.
¶3 At some point after his wife’s death, the husband married Ann Speers (appellee). The husband died some time before June of 2005, and upon searching his records, his second wife discovered the will. She filed her petition on June 2,2005, seeking to admit it to probate. The instrument submitted by the appellee contained several handwritten strikeouts and interlineations.1 On June 7, 2005, the testatrix’s children, Danny Speers, LeeAnn Fincher, and Sherry Ross (collectively, contestants) filed an objection to the petition for probate of the will and contest of the will, arguing that instrument was invalid because the original will was destroyed, thereby invalidating any copies.
¶ 4 On August 18, 2005, the trial court held a hearing on the matter and Durbin was called as a witness. Durbin testified that he remembered: 1) signing the instrument; 2) seeing the testatrix sign the instrument; and 3) that there were no strikeouts or interlinea-tions on the document he signed.2 Durbin testified that he had no recollection of: 1) being acquainted with Walton; 2) the location at which he signed the instrument; 3)
*1268seeing Walton sign the instrument; 4) hearing the testatrix state aloud “this is my -will;” 5) seeing the notary at the time he signed the instrument; or 6) seeing the testatrix initial the bottom of each page.3 Durbin also gave the following testimony:
Q. All right. Do you remember where you may .have been, wherever it was, when you signed the document?
A. I presume at the Church of Christ at Caney. She probably come to the church and asked me to sign it, I suppose, now, but I don’t know that, positive.
Q. Okay, that’s what we want to know, if you have a positive recollection of that. That’s where you think you may been; is that right?
A. Could have been, yes.
Q. But as you sit here today-and correct me if I’m wrong-but as you sit here today you don’t specifically remember this event, do you?
A. No....4
Walton was not produced to testify.
¶ 5 On August 18, 2005, the trial judge entered a court minute admitting the will to probate and appointing Doyle Wesley Fincher the executor. On September 12, 2006, the trial court filed a journal entry' of judgment finding:
1)the will was a photocopy of an original with original signatures attached;5
2) the will was not self-proving because it contained no notary seal;
3) the will was required to be proved by subscribing witnesses under 85 O.S. § 55(5) and 49 O.S. § 5;
4) there must be a showing that one of the subscribing witnesses is deceased or insane if that witness cannot testify, and the appellee made that showing;
5) the will was valid and was admitted; and
6) Doyle Wesley Fincher was named executor.
¶ 6 On September 29, 2006, the contestants filed their petition in error. On February 22, 2007, the cause was assigned to the Court of Civil Appeals. On September 21, 2007, the Court of Civil Appeals affirmed the ruling of the trial court. On October 9, 2007, the contestants filed their petition for certiorari, and we granted certiorari on January 22, 2008.
¶ 7 BECAUSE THERE WAS NOT SUFFICIENT EVIDENCE IN THE RECORD THAT THE INSTRUMENT WAS EXECUTED WITH THE PROPER STATUTORY FORMALITIES, THE INSTRUMENT SHOULD NOT HAVE BEEN ADMITTED TO PROBATE.
¶ 8 Probate proceedings are equita*1269ble in nature.6 Although this Court will examine and weigh the evidence, there is a presumption that the trial court’s decision is legally correct and cannot be disturbed unless found to be clearly contrary to the weight of the evidence or to some governing principle of law.7 Where the probate of a will is contested and the testimony is conflicting as to execution, the judgment of the trial court will not be disturbed if there is any substantial testimony supporting the judgment and finding.8 If legally correct, a district court’s ruling will not be reversed because of faulty reasoning, an erroneous finding of fact, or consideration of an immaterial issue.9
¶ 9 When a will is offered for probate, the singular concern of the court is the factum of the will, which consists of three elements: 1) whether the will has been executed with the requisite statutory formalities; 2) whether the maker was competent to make a will at the time; and 3) whether the will was the product of undue influence, fraud or duress.10 The emphasis of the judicial process is to discern and effectuate the decedent’s intent.11 The burden of proof in the trial of a contest of the probate of a will is upon the proponents of the will to make a prima facie showing that the will is adequate for probate; then the burden shifts to the contestants to establish the issues presented by their contest.12
¶ 10 The elements of a valid will and the method for making a self-proved will are found at 84 O.S. Supp.2004 § 55.13 Because there is no notary seal on the instrument, it is undisputed that the instrument is not a self-proved will.
¶ 11 Here, the contestants do not allege that the testatrix was incompetent to make a will, nor do they allege that the will was a product of undue influence, fraud, or duress. The contestants’ allegation is that the proponent did not make an adequate showing that the instrument was executed with the following statutory formalities: 1) *1270there were two attesting witnesses; 2) the instrument was signed by the testatrix in the presence of both attesting witnesses or that the testatrix acknowledged to both witnesses that the signature on the instrument was hers; 3) the testatrix declared to both the attesting witnesses that the instrument was her will; and 4) that both attesting witnesses subscribed the instrument at the testatrix’s request and in her presence.14
A.
The Trial Court Erred in Finding That There Were Two Subscribing Witnesses.
¶ 12 The burden of proof rests upon the proponent of the will to establish by preponderance of evidence that the will was executed and published according to law.15 Title 58 O.S.2001 § 43 provides in pertinent part:
If the will is contested, all the subscribing witnesses who are present in the county, and who are of sound mind, must be produced and examined; and the death, absence or insanity of any of them must be satisfactorily shown to the court. If none of the subscribing witnesses reside in the county, and are not present at the time appointed for proving the will, or although such witnesses reside in the county and are insane or incompetent, and such facts are first made to appear to the court, either in contested or noncontested will cases, the court may admit the testimony of other witnesses to prove the sanity of the testator and the execution of the will and, as evidence of the execution, it may admit proof of the handwriting of the testator and of the subscribing witnesses, or any of them_[Emphasis added.]
These statutory provisions clearly reflect an intent that, in the event of a will contest, the testimony of the subscribing witnesses is essential to prove the proper execution of the will.16 The contestants argue that Walton’s death was not satisfactorily shown to the trial court.
¶ 13 While Durbin was called to testify in the matter, evidence concerning Walton is de minimus. The instrument contains the signature of a Sadie B. Walton in three places: 1) in the attestation clause; 2) at the end of the instrument; and 3) in the notary’s section. The only evidence regarding Walton’s absence was the following exchange between the appellee’s counsel and Durbin:
Q: Are you familiar with Ms. Walton?
A: No, I can’t recall her, but I’m sure I knew her.
Q: All right. Do you understand that she’s now deceased?
A: I was told that.17
There is otherwise no evidence in the record that Walton was dead or unavailable at the time of the will contest. Section 43 mandates that all of the subscribing witnesses be present or that their absence or death must be “satisfactorily shown.”18
*1271¶ 14 The statute does not define the term “satisfactorily,” but this Court has recognized that the word “satisfy” means to be free from doubt, suspense, or uncertainty, to set the mind at rest, and satisfactory evidence, sometimes called “sufficient evidence,” is an amount of proof which will ordinarily satisfy an unprejudiced mind beyond a reasonable doubt.19 Under the facts presented, the trial court could not, as a matter of law, have made the requisite statutorily required finding that Walton’s absence or death was “satisfactorily shown.”
¶ 15 Durbin also testified that he was not sure whether Walton was present when he signed the will.20 The trial court’s determination that there were two subscribing witnesses based solely on Durbin’s testimony that he couldn’t recall Walton, that he had been told she was deceased, and that he wasn’t sure she was present when he signed the will is clearly contrary to the weight of the evidence.21
B.
The Trial Court Erred in Finding Substantial Compliance with the Statutory Requirements of Publication by the Testatrix and the Presence of the Testatrix and the Subscribing Witnesses at the Signature of the Other.
¶ 16 Title 84 O.S. Supp.2004 § 55(2) requires that a testatrix sign her will in the presence of two attesting witnesses, or acknowledge to the witnesses that the signature was made by her or her authority. Title 84 O.S. Supp.2004 § 55(3) requires that a testatrix declare or publish to two attesting witnesses that an instrument is her will. Title 84 O.S. Supp.2004 § 55(4) requires that two witnesses must sign a will at a testatrix’s request and in her presence. These are safeguards against imposition and fraud, and therefore require substantial compliance.22 Substantial compliance relating to the publication of a will and attesting by witnesses is all that is required, and no formal request *1272that witnesses sign or express declaration that instrument is testator’s will is required; but it is sufficient if the testator, by words or conduct, conveys to the witnesses that the instrument is his will and that he desires them to witness it.23
¶ 17 The evidence of the testatrix’s publication to Durbin offered by the appellee is the attestation clause and the following testimony by Durbin:
Q.... How did it happen that you became a witness to Ms. Speers’ will, if this, in fact, is her will?
A. Well, she came to me and wanted me to witness a will. And I told her I would, and I did....
Durbin also testifies that he saw the testatrix sign the instrument and that she was present when he signed the instrument.24 However, other than the attestation clause, there is no evidence whatsoever that: 1) the testatrix signed the instrument in Walton’s presence or acknowledged to Walton that the signature on the instrument was hers; 2) the testatrix published the instrument as her will to Walton; or 3) Walton signed the instrument in the testatrix’s presence.
¶ 18 This Court has held that where the attestation clause recites due execution of a will, it creates a prima facie case of due execution of the instrument, which can be overcome only by clear and convincing evidence.25 In proceedings for the probate of an instrument as a will where it appears to have been duly executed, and the attestation is established by proof of the handwriting of the witnesses or otherwise, although their testimony is not available, or they do not remember the transaction, it will be presumed, in the absence of evidence to the contrary, that the will was executed in compliance with all the requirements of law.26
¶ 19 Here, there was no evidence offered by the appellee establishing the attestation clause either by handwriting analysis, or any other form of proof. This is not sufficient to create a prima facie showing of due execution of the instrument, and therefore the instrument should not have been admitted to probate. The error concerning Walton’s unavailability coupled with the lack of evidence regarding its execution results in an instrument which should not have been admitted to probate.
*1273CONCLUSION
¶ 20 The formalities to be observed in the execution of wills are simple and calculated to prevent fraud and uncertainty in the testamentary dispositions of property. Where the Legislature has seen fit to impose certain requirements for the execution of a will, compliance with such requirements is necessary to the validity of any instrument offered as a will.27 Here, because of the absence of a notary seal, the will presented for probate was not self-proving. The evidence reflects that there was only one subscribing witness. A determination that there were two subscribing witnesses based solely on one witness’ testimony that he couldn’t recall the other witness, that he had been told she was deceased, and that he wasn’t sure she was present when he signed the will is clearly contrary to the weight of the evidence. The evidence does not establish that the testatrix substantially complied with the statutory requirements for execution and publication. The proponent of the will neglected to make a proper showing that the will was suitable for probate. Therefore, we reverse the trial court and remand with instructions that the will not be admitted to probate.

. Title 84 O.S. Supp.2004 § 55 provides in pertinent part:
Every will, other than a nuncupative will, must be in writing; and every will, other than a holographic will and a nuncupative will, must be executed and attested as follows:
1. It must be subscribed at the end thereof by the testator himself, or some person, in his presence and by his direction, must subscribe his name thereto.
2. The subscription must be made in the presence of the attesting witnesses, or be acknowledged by the testator to them, to have been made by him or by his authority.
3. The testator must, at the time of subscribing or acknowledging the same, declare to the attesting witnesses that the instrument is his will.
4. There must be two attesting witnesses, each of whom must sign his name as a witness at the end of the will at the testator’s request and in his presence.
5. Every will, other than a holographic and a nuncupative will, and every codicil to such will or to a holographic will may, at the time of execution or at any subsequent date during the lifetimes of the testator and the witnesses, be made self-proved, and the testimony of the witnesses in the probate thereof may be made unnecessary by:
a. the acknowledgment thereof by the testator and the affidavits of the attesting witnesses, each made before an officer authorized to take acknowledgments to deeds of conveyance and to administer oaths under the laws of this state, such acknowledgments and affidavits being evidenced by the certificate, with official seal affixed, of such officer attached or annexed to such testamentary instrument.... [Emphasis added.]
.The contestants have also alleged that the handwritten strikeouts and interlineations operate to revoke the instrument as a will. Any handwritten codicil must conform to the requirements for holographic wills. Because none of the handwritten changes to the will were signed or dated, the changes are not valid codicils. 84 O.S.2001 § 54.
A will may be revoked by physical act only if there is a physical act within the meaning of the statute, and if the act is performed within the intent and purpose to revoke. In re Estate of Ausley, 1991 OK 105, ¶ 13, 818 P.2d 1226; In re Cabler’s Estate, 1927 OK 126, ¶ 11, 257 P. 757. A mere interlineation in a will after its execution is not a revocation, where nothing was added to or taken from the meaning and no intent to revoke was thereby indicated. In re Ballard’s Estate, 1916 OK 271, ¶ 0, 155 P. 894. There was no showing by either party that the testatrix intended to revoke the will or that the testatrix, or someone she directed, wrote the strikeouts or interlineations, so there cannot be a revocation. Because the handwritten portions of the will do not constitute valid codicils or a revocation, they must be disregarded.

. Evidence of Walton’s death was readily available to the appellee. A quick search of the Social Security Death Index shows that Walton died on August 15, 2000 and that her last place of residence was Atoka, Oklahoma, http.ilssdi. rootsweb.com/cgi-bin/ssdi.cgi.
. In Midland Valley R. Co. v. Barnes, 1933 OK 26, ¶ 5, 18 P.2d 1089, the Court, quoting a Tennessee case, discussed whether a jury is to be satisfied whether evidence does or does not preponderate and examined the words "satisfy” and "satisfactory evidence.” In Board of Com'rs of Garfield County v. Anderson, 1934 OK 6, ¶ 46, 29 P.2d 75, the Court described a requirement that intent be satisfactorily shown as that which is clear and unequivocal. "Satisfactory evidence" has been described as that evidence which ordinarily produces moral certainty or conviction in an unprejudiced mind, such as ordinarily satisfies such a mind beyond a reasonable doubt. Shriver v. Union Stockyards Nat. Bank, 117 Kan. 638, 232 P. 1062, 1066 (1925). Whatever "satisfactorily shown” is, it must be more than one witness' testimony that he couldn’t recall the other witness, that he had been told she was deceased, and that he wasn't sure she was present when he signed the will.
. Testimony of Walter Francis Durbin, see ¶ 4.
. The contestants' counsel did not object to Durbin’s testimony that he had been told that Walton was deceased. Title 12 O.S.2001 § 2104 provides in pertinent part:
A. Error may not be predicated upon a ruling which admits or excludes evidence unless a substantial right of a party is affected, and:
1. If the ruling is one admitting evidence, a timely objection or motion to strike appears of record, stating the specific ground of objection, if the specific ground was not apparent from the context
[[Image here]]
D. Nothing in this section precludes taking notice of plain errors affecting substantial rights although they were not brought to the attention of the court.
In United States v. Atkinson, 297 U.S. 157, 160, 56 S.Ct. 391, 80 L.Ed. 555 (1936), the United States Supreme Court has held: "In exceptional circumstances, especially in criminal cases, appellate courts, in the public interest, may, of their own motion, notice errors to which no exception has been taken, if the errors are obvious, or if they otherwise seriously affect the fairness, integrity or public reputation of judicial proceedings.” The doctrine of plain error is rarely applied in civil cases and usually reserved to prevent a clear miscarriage of justice. Chestnut v. City of Lowell, 305 F.3d 18, 20 (1st Cir.2002); Crawford v. Falcon Drilling Co., Inc., 131 F.3d 1120, 1123 fn. 3 (5th Cir.1997); Polys v. Trans-Colorado Airlines, Inc., 941 F.2d 1404, 1408 fn. 5 (10th Cir.1991).
Here, we need not reach the question of whether the trial court’s admission of Durbin’s testimony was plain error. Even if the testimony was properly admissible evidence, the trial court’s determination that there were two subscribing witnesses was clearly contraiy to the weight of the evidence.

. Hobbs v. Mahoney, 1970 OK 209, ¶ 12, 478 P.2d 956; Goff v. Knight, see note 25, supra at V 13. Title 84 O.S.2001 145 addresses subscribing witnesses made unavailable by reason of incompetency. It provides:
If the subscribing witnesses to a will are competent at the time of attesting its execution, their subsequent incompetency, from whatever cause it may arise, does not prevent the probate and allowance of the will, if it is otherwise satisfactorily proved.
Several other jurisdictions also permit the execution of will to be established without the testimony of one or both of the subscribing witnesses, but most require the proponent to establish execution by some other method of proof. In re Will of McCauley, 356 N.C. 91, 565 S.E.2d 88, 92 (2002) [if witnesses are unavailable or have no memory of the event, execution may be established by other credible evidence]; Upton v. Upton, 26 Ark.App. 78, 759 S.W.2d 811, 813 (1988) [presumption of due execution if witness’ handwriting matches]; In re Estate of Nelson, 447 A.2d 438, 439 (Del.1982) [if unavailable witness, execution may be established by other means]; Modlin v. Riggle, 399 N.E.2d 767, 770 (Ind.Ct.App.1980) [if witnesses unavailable, execution may be proven by handwriting per statute]; Ross v.
