OPINION

CORNELIA A. CLARK, J., delivered the opinion of the Court, in which GARY R. WADE, C.J., and JANICE M. HOLDER, WILLIAM C. KOCH, JR., and SHARON G. LEE, JJ., joined.

The issue in this appeal is whether the statutory requirements for execution of an attested will prescribed by Tennessee Code Annotated section 32-1-104(1) (2007) were satisfied when the decedent failed to sign the two-page will but signed a one-page affidavit of attesting witnesses. We conclude that the decedent's signature on the separate affidavit of attesting witnesses does not satisfy the statute requiring the testator's signature on the will. Accordingly, the judgment of the Court of Appeals is reversed, and the judgment of the trial court that the will was not properly executed is reinstated.

Factual and Procedural History

Thomas Grady Chastain ("Decedent") died on November 6, 2009. On April 30, 2010, Decedent's daughter, June Chastain Patterson, filed a petition for the administration of his estate. Ms. Patterson alleged that Decedent died intestate and that she was Decedent's "sole surviving heir." Ms. Patterson sought appointment as administrator of Decedent's estate as well as a waiver of bond and inventory. Ms. Patterson's requests were granted the day she filed the petition, and letters of administration issued.

On July 7, 2010, Trent and Adrian Chastain ("Chastains"1), two of Decedent's grandchildren, filed a motion for bond, inventory, and an accounting of Decedent's estate. The Chastains alleged that Ms. Patterson had falsely sworn to being Decedent's sole heir, that Decedent had two predeceased sons, and that the six surviving issue of Decedent's predeceased sons are also his heirs and entitled to a share of his estate under the laws of intestacy.

Notwithstanding her prior petition alleging that Decedent died intestate, on August 24, 2010, the date of the hearing on the Chastains' motion, Ms. Patterson "deposited" with the trial court a consecutively numbered, two-page document dated September 4, 2004, and titled "Last Will and Testament" ("Will"). The first paragraph of the Will is reproduced below.

The Will named Decedent's grandchildren and great-grandchildren and bequeathed to them his knife collection and any insurance monies remaining after Decedent's bills had been paid. The Will bequeathed the remainder of Decedent's estate to Ms. Patterson and named her as executrix. Decedent's initials, the initials of three witnesses, and the date appear at the bottom of the first page of the Will as follows:

Initials: Testator Witness Witness Witness Date

Although the second page of the Will, reproduced below, includes the signatures of three witnesses and a blank line on which Decedent's name apparently should have been printed, the Will included no blank line for Decedent's signature, and Decedent's signature is not on this page of the Will.2

However, Decedent and the attesting witnesses signed a separate one-page document titled "Self-Proved Will Affidavit" ("Affidavit") that Ms. Patterson submitted along with the Will. The Affidavit is reproduced in its entirety below.

On September 7, 2010, the Chastains filed a motion for declaratory judgment seeking a determination of the validity of the Will. The Chastains argued that Decedent had not signed the Will and that his signature on the Affidavit did not satisfy the statute requiring the testator's signature on a will.3 See Tenn.Code Ann. § 32-1-104 (2007) (prescribing the manner in which a will, other than a holographic or noncupative will, must be executed). On October 15, 2010, before the trial court ruled on the Chastains' declaratory judgment motion, Ms. Patterson filed a petition to probate the Will. On November 17, 2010, the Chastains filed a notice of contest, again challenging the Will's validity based on Decedent's failure to sign it as required by statute.

On January 24, 2011, the trial court entered an agreed order that scheduled a hearing for February 9, 2011, to decide only the question of whether Decedent executed the Will as required by statute. The parties presented no proof at the February 9, 2011 hearing and asked the trial court to decide the issue based on the Will and the Affidavit alone.

The Chastains argued that Decedent failed to sign the two-page Will as required by Tennessee Code Annotated section 32-1-104, that the separate Affidavit is not part of the Will, and that Decedent's signature on the Affidavit is not sufficient because Tennessee law does not recognize the doctrine of integration. In response, Ms. Patterson argued that the Will includes the Affidavit and that Decedent's signature on the Affidavit satisfies Tennessee Code Annotated section 32-1-104.

On March 14, 2011, the trial court ruled in favor of the Chastains, concluding "that the four corners of these documents do not make a will." The trial court also concluded that Decedent's initials on the first page of the Will are not a signature, that Decedent failed to sign the second page of the Will, and that Decedent's signature on the Affidavit is not sufficient because Tennessee law requires "strict compliance in the execution of wills."

The trial court granted Ms. Patterson permission to seek a Tennessee Rule of Appellate Procedure 9 interlocutory appeal, and the Court of Appeals granted Ms. Patterson's Rule 9 application. A divided panel of the Court of Appeals reversed the trial court's judgment. In re Estate of Chastain, No. E2011-01442-COA-R9-CV, 2011 WL 6916459, at *1 (Tenn.Ct.App. Dec. 28, 2011). The majority held that Decedent's signature on the Affidavit satisfied Tennessee Code Annotated section 32-1-104 because Decedent "intended his signature on the [A]ffidavit to be his signature on the Will." Id. at *3. The majority thus found it unnecessary to decide whether the integration doctrine, which "treats an affidavit as integrated into the will in order to sustain its validity," should be adopted in Tennessee. Id. at *5.

In his dissenting opinion, Judge D. Michael Swiney opined that Decedent failed to sign the Will as required by Tennessee Code Annotated section 32-1-104. Id. (Swiney, J., dissenting). Judge Swiney viewed the Affidavit as a separate document from the Will, pointing to language in the Affidavit instructing that it be attached to the Will and referring to the Will as a separate document. Id. at *6. Judge Swiney concluded that a testator's failure to sign a will is not cured by a testator's signature on a separate document. Id. Judge Swiney also explained that courts are not at liberty to dispense with statutory mandates concerning the execution of a will. Id. at *7.

We granted the Chastains permission to appeal.

Standard of Review

The issue in this appeal is whether Decedent satisfied the statutory requirements for execution of an attested will.4 The facts relevant to this issue are undisputed, and we review this question of law de novo, according no presumption of correctness to the conclusions of the courts below. In re Estate of McFarland, 167 S.W.3d 299, 302 (Tenn.2005); In re Estate of Stringfield, 283 S.W.3d 832, 834 (Tenn.Ct. App.2008).

Analysis

The Legislature has the authority to prescribe the conditions by which property may be transferred by will in this State. Epperson v. White, 156 Tenn. 155, 299 S.W. 812, 815 (1927); Eslick v. Wodicka, 31 Tenn.App. 333, 215 S.W.2d 12, 15 (1948). The General Assembly exercised this power in 1941 by enacting the Execution of Wills Act.5 See Act of Feb. 14, 1941, ch. 125, 1941 Tenn. Pub. Acts 449. This legislation prescribed uniform standards for the execution of attested wills.6 These statutory requirements have remained virtually unchanged in the ensuing seventy-one years7 and are currently codified in Tennessee Code Annotated section 32-1-104, which provides:

(footnote added). This statute gives a testator some latitude in the manner of signing an attested will.9 The testator may either sign the will in the presence of the attesting witnesses, or acknowledge a signature already made in the presence of attesting witnesses, or direct someone else to sign the will in the presence of the testator and of the attesting witnesses. Tenn.Code Ann. § 32-1-104(1)(A)-(D). But the statute demands that the testator's signature be placed on the will by one of these means. Id. The testator's signature is essential to the creation of a will. See Simmons v. Leonard, 91 Tenn. 183, 18 S.W. 280, 282 (1892) ("[T]here can be no valid attestation or subscription unless it be a fact that the testator has actually signed his name, or caused it to be signed, before [the witnesses] subscribed their names. There is no will to witness until it has been signed by the testator.").

Tennessee courts have consistently interpreted statutes prescribing the formalities for execution of an attested will as mandatory and have required strict compliance with these statutory mandates. See, e.g., Fann v. Fann, 186 Tenn. 127, 208 S.W.2d 542, 544 (1948) (holding that the will had not been properly executed where the attesting witnesses failed to sign it in each other's presence); In re Estate of Stringfield, 283 S.W.3d at 832 (holding that the will was not properly executed where the attesting witnesses failed to sign the will but initialed the first two pages of the will and submitted an affidavit of attesting witnesses); In re Estate of Wait, 43 Tenn.App. 217, 306 S.W.2d 345, 349 (1957) (holding that the will had not been properly executed where the testatrix failed to sign it at the same time and in the presence of the attesting witnesses); Ball v. Miller, 31 Tenn.App. 271, 214 S.W.2d 446, 450 (1948) ("Certain acts required in the execution of wills we view as mandatory[,] and an instrument does not attain the character admissible to probate unless and until they are performed."); Eslick, 215 S.W.2d at 15 (holding that the will had not been properly executed where the attesting witnesses signed it separately and later acknowledged their signatures in the presence of the testator and each other); see also Pritchard § 4, at 10 ("[I]t is indispensable that every requirement of the Tennessee Execution of Wills Act be complied with in the execution of a will."). Statutes requiring the observance of formalities in the execution of wills are designed to prevent fraud, mistakes, and uncertainty in the testamentary dispositions of property. Ball, 214 S.W.2d at 449-50. Enforcing strict compliance with such statutory formalities is intended to preserve "the inviolability" and "sanctity" of a testator's right to dispose of property by will. Id. at 449. "While in some cases a relaxation in the enforcement of these statutory provisions, or a liberal construction thereof, might appear to be justified, in many instances such a practice would serve only to thwart the testator's purposes." Id. at 449-50. Accordingly, Tennessee courts will sustain a will as legally executed only if it is possible to do so consistently with statutory requirements. Leathers v. Binkley, 196 Tenn. 80, 264 S.W.2d 561, 563 (1954).

With these principles in mind, we turn to the undisputed facts of this case. The parties agree that Decedent failed to sign the Will.10 The dispute focuses on the legal effect, if any, of Decedent's signature on the Affidavit. The Chastains argue that Decedent's signature on the Affidavit does not cure his failure to comply strictly with the statutory formalities for executing an attested will. The Chastains maintain that the Affidavit is a separate document from the Will and intended for use in a probate court only if a will is uncontested.

On the other hand, Ms. Patterson argues that Decedent's signature on the Affidavit satisfies the statutory formalities because: 1) Decedent and the attesting witnesses signed the Affidavit on the same day the witnesses signed the Will; 2) Tennessee law recognizes that a will may consist of multiple documents and the Affidavit was found with the Will; 3) the statute does not require a testator to sign a will in a particular location; and 4) Decedent intended to sign the Will when he signed the Affidavit.

We hold that Decedent's signature on the Affidavit does not cure his failure to comply strictly with the statutory formalities for executing an attested will. Despite Ms. Patterson's assertion to the contrary, the Affidavit is not part of the Will. The Affidavit was prepared pursuant to Tennessee Code Annotated section 32-2-110, which states:

Tenn.Code Ann. § 32-2-110 (2007). This statute authorizes use of an affidavit of attesting witnesses in lieu of live testimony only if a will is uncontested. See Pritchard § 210, at 328 ("[A]n affidavit of an attesting witness, instead of resorting to testimony of the witness in open court, may be used to prove a will unless the will is contested.... The customary practice is for attesting witnesses to also sign affidavits at the time the will is executed, so that later probate of the will will be facilitated."). By requiring the affidavit to "be written on the will or, if that is impracticable, on some paper attached to the will," Tenn.Code Ann. § 32-2-110, a clear distinction is drawn between an affidavit of attesting witnesses and a will.

This distinction is also apparent from the language of the Affidavit at issue in this appeal. The instructions — "(attach to Will)" — are printed on the Affidavit immediately below the title "Self-Proved Will Affidavit." The first paragraph of the Affidavit refers to the Will as "the attached or foregoing instrument." Simply put, both the statute and the Affidavit establish that the Affidavit is not a continuation of the Will. Accordingly, Decedent's signature on the Affidavit is not sufficient to satisfy the statutory requirement that he sign the Will by one of the means provided by statute.

Our holding should not be interpreted as requiring a testator to sign each page of a will that is written on several detached sheets of paper. See Gass' Heirs v. Gass' Ex'rs, 22 Tenn. (3 Hum.) 278, 284-85 (Tenn.1842). Nor does our holding require a testator to sign in a particular location on the will because Tennessee Code Annotated section 32-1-104 is silent on this issue. See Pritchard § 205, at 322 ("Neither ... former T.C.A. § 32-109 nor the Tennessee Execution of Wills Act of 1941 contains any provision as to the part of the will at which [the testator's] signature must appear." (footnote omitted)). We hold only that a testator must sign the will, not a wholly separate document. Here, Decedent failed to sign either of the two consecutively numbered pages that constituted the Will. Decedent's signature on the wholly separate Affidavit does not rectify his failure to sign the Will.

Ms. Patterson asserts that Decedent signed the Affidavit intending to sign the Will and believing he was signing the Will, so his signature on the Affidavit should be deemed sufficient.11 Decedent's signature on the separate Affidavit provides little, if any, insight about Decedent's beliefs and intentions concerning the unsigned two-page Will. Even assuming Ms. Patterson's assertion is correct, however, our conclusion remains the same. Courts endeavor to effectuate a testator's intent "unless prohibited by a rule of law or public policy," In re Estate of McFarland, 167 S.W.3d at 302, and courts will sustain a will as legally executed if it can be done consistently with statutory requirements, Leathers, 264 S.W.2d at 563. However, courts may not ignore statutory mandates in deference to a testator's intent. Ball, 214 S.W.2d at 449-50. Irrespective of Decedent's intent, we have no authority to dispense with the statute mandating Decedent's signature on the Will, and Decedent's signature on the Affidavit simply is not sufficient to satisfy this requirement.

Ms. Patterson also asks us to adopt the doctrine of integration by which "a separate writing may be deemed an actual part of the testator's will, thereby merging the two documents into a single instrument." In re Will of Carter, 565 A.2d 933, 936 (Del.1989). As Ms. Patterson recognizes, this doctrine has not been judicially adopted in Tennessee, and the General Assembly has not enacted Section 2-504(c) of the Uniform Probate Code, which provides that "[a] signature affixed to a self-proving affidavit attached to a will is considered a signature affixed to the will, if necessary to prove the will's due execution." Unif. Probate Code § 2-504(c) (2008). Rather, Tennessee Code Annotated section 32-1-104 plainly and unambiguously requires a testator's signature to appear on the will. This statutory requirement has been in place and strictly enforced for seventy-one years. The Legislature has neither relaxed this requirement nor provided that it may be satisfied by the testator's signature on a document separate from the will. "[T]he [L]egislature's failure to `express disapproval of a judicial construction of a statute is persuasive evidence of legislative adoption of the judicial construction.'" Freeman Indus. v. Eastman Chem. Co., 172 S.W.3d 512, 519 (Tenn.2005) (quoting Hamby v. McDaniel, 559 S.W.2d 774, 776 (Tenn.1977)). As already noted, the Legislature is the entity authorized to prescribe the conditions by which property may be transferred by will in this State, Epperson, 299 S.W. at 815, and courts have no authority to modify those conditions. Ball, 214 S.W.2d at 450. Given the Legislature's adoption of statutes prescribing the manner of executing an attested will and its tacit approval of court decisions strictly enforcing those statutory mandates, we decline to adopt the doctrine of integration because doing so would amount to a relaxation of statutory requirements. Whether the doctrine of integration should be adopted is a matter for the Legislature. See In re Estate of McFarland, 167 S.W.3d at 305-06 (declining to overrule a longstanding judicial decision regarding the appropriate manner of distributing lapsed residuary gifts in a will but recognizing the General Assembly's prerogative to adopt another "`modern' rule.").

Conclusion

We conclude that Decedent's signature on the Affidavit does not satisfy the statute requiring the testator's signature on a will. Accordingly, the judgment of the Court of Appeals is reversed, and the judgment of the trial court finding that the Will had not been properly executed is reinstated. This matter is remanded to the trial court for any further necessary proceedings consistent with this opinion. Costs of this appeal are taxed to Ms. Patterson and her surety, for which execution may issue if necessary.
