OPINION
PRICE, Justice(Assigned).
This appeal is from a summary judgment, holding that a writing on the back of a greeting card constituted a valid holographic will.
On October 19, 1989, Bill Hayes Daniels was killed in an automobile/train collision. At the time, he was 36 years old and a practicing attorney. On December 14, 1989, Verneice Daniels filed an application to probate a holographic will. The will was probated as a muniment of title on January 3,1990. It consists of a short declaration, handwritten on the backside of a printed greeting card. It reads as follows:
Last Wifi:
I leave everything to Verneice Daniels.
BHD.
Note: Handle pursuant to the incomplete will that Doris has.
A poem entitled: “The Ten Secrets of a Successful Relationship” was printed on the frontside of the greeting card. At the bottom of the frontside, the decedent signed his full name, Bill Hayes Daniels. Underneath his signature, “(on back)” is written. Appel-lee received the greeting card in the mail. The envelope was hand-addressed by the decedent. His name and return address were handwritten at the top lefthand corner on the front of the envelope. It was postmarked September 29, 1989. The “incomplete will” was not made a part of the record, and thus, is not before this Court.
On February 22, 1990, appellant filed a petition contesting the validity of the will, maintaining the decedent died intestate. Both appellant and appellee claim to be the common-law wife of the decedent. Appellant has a son, Theron, who she maintains is the issue of her common-law marriage with the decedent. Both parties moved for summary judgment. On November 30, 1990, the trial court rendered judgment sustaining appel-lee’s motion and finding that the writing constituted a valid holographic will signed by the testator with clear testamentary intent.
The standards for reviewing a summary judgment are:
1. The movant for summary judgment has the burden of showing there is no genuine issue of material fact, and that it is entitled to judgment as a matter of law.
2. In deciding whether there is a disputed material fact issue precluding summary judgment, evidence favorable to the nonmovant will be taken as true.
3. Every reasonable inference must be indulged in favor of the nonmovant and any doubts resolved in its favor.
Nixon v. Mr. Property Management Co., Inc., 690 S.W.2d 546, 548-49 (Tex.1985).
Appellant does not challenge the authenticity of the handwriting. Rather, in three points of error, she asserts there are fact issues regarding whether the decedent intended the writing to be a holographic will. Specifically, she alleges: (1) the writing does not identify the name of the testator, it merely says “Last Will;” (2) because there is no antecedent for the pronoun “I,” the testator is incapable of being determined; (3) the initials at the end of the statement do not properly identify the testator; and (4) the statement “Note: Handle pursuant to the incomplete will that Doris has,” indicates the writing is not the decedent’s will.
A valid will is a document executed with testamentary intent. The animus tes-tandi does not depend on the maker’s realization that he is making a will, or upon his designation of the instrument as a will, but upon his intention to create a revocable disposition of his property to take effect after *10his death. It is essential, however, that the maker shall have intended to express his testamentary wishes in the particular instrument offered for probate. Hinson v. Hinson, 154 Tex. 561, 280 S.W.2d 731, 735 (1955).
To be considered for its testamentary effect, a holographic instrument must be wholly in the handwriting of the decedent. Gillispie v. Reinhardt, 596 S.W.2d 558, 559 (Tex.Civ.App.—Beaumont 1980, writ ref'd n.r.e.); Gunn v. Phillips, 410 S.W.2d 202, 205 (Tex.Civ.App.—Houston 1967, writ ref'd n.r.e.); Tex.Prob.Code Ann. art. 84(b) (Vernon Supp.1992). A signature by initials is sufficient to execute the instrument as a will, if it is testamentary in character, and it need not be dated. Gillispie, 596 S.W.2d at 559; Gunn, 410 S.W.2d at 207; Barnes v. Horne, 233 S.W. 859, 860 (Tex.Civ.App.—Austin 1921, no writ). A holographic will should be liberally construed to effect the testator’s intent because the law favors testate over intestate passage of property. Lane v. Sherrill, 614 S.W.2d 619, 622 (Tex.1981); Gilkey v. Chambers, 207 S.W.2d 70, 73 (Tex.1947).
It is significant to note here, that decedent, at the time he executed the holographic will, was a practicing attorney. As such, we analyze the questioned document as one written by a person with knowledge of the form and wording of a will. See Bergin v. Bergin, 315 S.W.2d 943, 947 (Tex.1958) (lay person cannot be deemed to have used words in the same technical sense the words might have if they were used by an attorney). Paying deference to one with such knowledge, we conclude that the only rational interpretation of the instrument in question is that “BHD” intended to bequeath his entire estate to Verneice Daniels upon his death. The language is clear, direct, and unambiguous. The front side of the greeting card even directed the reader to the backside so that the written information would not be overlooked. Because appellant has challenged neither the identity of “BHD,” as that of the decedent, nor the identity of Verneice Daniels, as that of beneficiary, we must conclude the decedent intended to will all of his property to appellee.
Appellant asserts the statement following decedent’s initials, “Note: Handle pursuant to the incomplete will that Doris has,” destroys any testamentary intent decedent might otherwise have expressed in the writing above the initials. As noted earlier, the record reflects no reference to an incomplete will in Doris’ possession. The only reference to an incomplete will appears in decedent’s brother’s affidavit, wherein, he makes mention of having seen a document in Verneice’s possession that devised a $20,000 gift to appellant’s son, Theron. The affidavit stated that while the document was unsigned, it was in decedent’s handwriting.
We point out that the questioned phrase follows decedent’s initials and is an instructional “note.” For this phrase to have significance, affecting decedent’s testamentary intent, the incomplete will must be capable of being identified and incorporated by reference, thus, made a part of the holographic will.
However, we conclude the statement making reference to an “incomplete will” does not identify and incorporate such instrument. The words “pursuant to” are not equivalent to “incorporated.” Mere reference to the “incomplete” document is not only insufficient for incorporation, but insufficient to adequately describe such document for it to be capable of identification. The testator’s intention to incorporate by reference must be clearly expressed in the will. See Taylor v. Republic Nat’l Bank of Dallas, 452 S.W.2d 560, 563 (Tex.Civ.App.—Dallas 1970, writ ref'd n.r.e.) (a reference to an “attached” document is neither sufficient to incorporate by reference nor sufficient to describe the document with particularity). The instruction, “handle pursuant to,” following his testamentary intent, is an expression of the decedent’s desire for his survivor to manage and dispose of his estate in a particular manner. It is not intended to control the disposition of his estate. It is an expression of his desire not of his will, thus, lacks testamentary character. It must be disregarded in favor of his general intent.
Decedent’s intent was clear when he signed the will, “I leave everything to Ver-neice Daniels.” He obviously intended to *11leave Ms entire estate to Verneiee. The instructional “note” is merely precatory, not mandatory, therefore, it can have no binding legal effect. See Taylor, 452 S.W.2d at 560 (a residual bequest to a religious group for the purpose of establishing, constructing, and administrating a hospital, while a legitimate charitable bequest, was not enforceable as to the establishment of the hospital because the purpose clause was merely precatory and could not replace testator’s mandatory intent of making a charitable gift); Langehennig v. Hohmann, 139 Tex. 452, 163 S.W.2d 402, 406 (1942) (a document, executed subsequent to preexisting wills, expressing the desires and wishes of the testators for the manner in which the final distribution of their estate and property was to be made was not subject to probate because such directions were precatory and not mandatory).
Thus, it is our opinion that, as a matter of law, the decedent intended Ms property should pass and vest, not by the provision of the mstructional note, but under and in accordance with the statement preceding his initials
Appellant’s first three points of error are overruled.
In her fourth pomt of error, appellant asserts the trial court erred in not granting her motion for summary judgment. Because of our disposition of points of error one, two, and three, appellant’s fourth pomt of error is likewise overruled.
The summary judgment is affirmed.
