In In re Estate of Aldrete, a decedent’s son from a first marriage had a 1981 will admitted to probate, which left real property to him. No. 04-20-00426-CV, 2022 Tex. App. LEXIS 322 (Tex. App.—San Antonio January 19, 2022, no pet. history). Later, a second son from a second marriage filed a motion to set aside the 1981 will and admit a newer 2008 will, which left the real property to the decedent’s second wife, the second son’s mother. After the court granted the motion, the first son appealed. The first son initially complained about the process followed by the trial court. The court of appeals disagreed, stating:

Appellant argues that because appellees never initiated a “separate” proceeding to probate the 2008 will, the trial court erred in not analyzing the case as a “will contest,” and errantly analyzed the case as a second application for probate. Section 256.102—governing the procedure on filing of a second application for probate after first will has been admitted—provides in relevant part: “If, after a decedent’s will has been admitted to probate, an application is filed for the probate of a will of the same decedent that has not previously been presented for probate, the court shall determine: (1) whether the former probate should be set aside; and (2) if the former probate is to be set aside, whether: (A) the other will should be admitted to probate . . . “Tex. Est. Code § 256.102. Appellee’s motion to set aside order admitting the 1981 will to probate requested the following relief: “[Appellees] pray . . . that the former probated will dated 7/15/81 be set aside; that the ‘decedent’s’ will dated 10/14/08 be admitted to probate; that Jessica Galvan, be appointed Executrix; [and] that letters testamentary be issued to her . . .” Given the substance of the motion and its requested relief, appellees clearly sought to both contest the 1981 will and admit the 2008 will. Because appellees sought probate of the 2008 will after the 1981 will was admitted to probate, the trial court was required to (“shall”) determine whether the 1981 will should be set aside and, if so, whether the 2008 will should be admitted to probate. See Tex. Est. Code § 256.102. The trial court did not err in doing so.

Id. The court also held that a former accountant had sufficient knowledge of the decedent’s hand writing to prove up his signature on the 2008 will: “Here, the record discloses the witness knew decedent and his wife since 2002, did bookkeeping work for both for twelve years, and was familiar with decedent’s signature based on bookkeeping documents. This evidence is not so weak as to make the trial court’s finding that the witness was familiar with decedent’s signature clearly wrong and manifestly unjust.” Id.

The court also held that witnesses did not have to have medical training to testify regarding mental competence:

Appellant’s complaint is that the notary could not competently testify as to whether decedent was of sound mind because she did not have “any medical training.” The law, however, does not require medical training. The notary testified to the following: (1) when she walked into decedent’s hospital room, he was discussing documents with a nurse; (2) she had decedent read the will prior to signing; (3) she read a portion of the will to decedent; (4) decedent verbally confirmed he was aware of what he was signing and where he was; (5) decedent responsively answered her questions; (6) decedent verbally acknowledged the witnesses in the room; (7) decedent was “spot on” in interactions, did not pause in answering questions, and was “real matter of fact”; and (8) decedent confirmed he was leaving his property to his wife. We are satisfied the notary’s conversation and observations are sufficient to reasonably form an intelligent opinion decedent was of sound mind. Accordingly, the evidence supporting the trial court’s finding is not so weak as to make the finding clearly wrong and manifestly unjust.

Id. The court finally found that the medical expert, who was an anesthesiologist, was competent to testify regarding the decedent’s capacity to execute a will:

Appellant also challenges the trial court’s finding that appellee’s medical expert found the decedent to be “oriented, alert and communicative.” The expert is a board certified anesthesiologist who has administered operative anesthesia to over 35,000 patients during his medical career. Based on his review of 639 pages of medical records, the expert opined decedent was competent to execute the will at the time it was executed—hours before the administration of anesthesia. The medical records disclosed attendant nurses and the anesthesiologist found multiple times that decedent was alert, oriented, responsive, and communicative prior to the administration of anesthesia. These are medical conclusions—not legal conclusions. After being confronted with the legal definition of “testamentary capacity” on cross-examination, the expert opined that decedent understood the business matter in which he was engaged and had the capacity to understand the effect of what he was signing.  The expert’s conclusions are not so against the great weight of the evidence as to be manifestly wrong.
