Undue Influence Claims Survive Summary Judgment Where Record Shows Triable Issues and Proponent Concedes Credibility Disputes — Matter of Estate of Mielty (Mielty)

1. Introduction

Matter of Estate of Mielty (Mielty) (2026 NY Slip Op 03531 [4th Dept June 5, 2026]) arises from a late-life estate-plan overhaul. Less than two months before his death, Archie J. Mielty executed a new will dated June 30, 2021 and amended the Archie J. Mielty Revocable Trust (dated October 12, 2010), shifting an equal division between his two sons to an outright transfer of essentially all assets to one son, petitioner-respondent John E. Mielty. The other son, objectant-appellant James V. Mielty, challenged probate and separately challenged the trust amendment under SCPA § 2102.

The core issues were (1) whether the June 30, 2021 will was duly executed under EPTL 3-2.1; (2) whether the decedent had testamentary capacity at execution; and (3) whether the will and trust amendment were products of undue influence—an inquiry distinct from capacity. After discovery, each side moved for summary judgment. Surrogate’s Court granted petitioner’s cross-motion, dismissed all objections (including undue influence), and admitted the will to probate (and, in the related trust order, upheld the amendment).

2. Summary of the Opinion

The Fourth Department unanimously modified the probate order. It affirmed the rulings that (a) the will was duly executed and (b) the decedent had testamentary capacity as a matter of law on this record. However, it held Surrogate’s Court erred in dismissing undue influence. The Appellate Division reinstated the undue influence objection, vacated the decree admitting the will to probate, and directed that the matter proceed because triable issues exist regarding a confidential relationship and undue influence—issues that typically turn on credibility and circumstantial proof.

Although the opinion also discusses the companion trust appeal, the legal thrust is the same: undue influence could not be summarily disposed of where the record itself revealed disputed material facts, and where petitioner’s counsel conceded the undue influence issue “cannot be determined on summary judgment” because credibility disputes require trial.

3. Analysis

3.1 Precedents Cited

A. Due execution: strict statutory formalities, but powerful presumptions when supervised and self-proved

Matter of Lewis, 114 AD3d 203, 211 (4th Dept 2014), mod 25 NY3d 456 (2015): Cited for the “relatively strict observance” of EPTL 3-2.1 formalities (signature at end; acknowledgement in presence of witnesses; publication; two witnesses; timely attestation and addresses). The court uses Lewis as the blueprint for what must be shown—and then explains why presumptions carried the proponent’s burden here.
Matter of Fraccaro, 161 AD3d 1275, 1276 (3d Dept 2018), lv denied 32 NY3d 911 (2018): Cited for the proponent’s burden (preponderance) and for a straightforward application of EPTL 3-2.1. Fraccaro frames the evidentiary baseline: the proponent must prove validity; objectant must bring “positive proof” to defeat execution presumptions.
Matter of Walker, 124 AD3d 970, 972 (3d Dept 2015) and Matter of Falk, 47 AD3d 21, 26 (1st Dept 2007), lv denied 10 NY3d 702 (2008): Reinforce that the proponent carries the burden by a preponderance; the court cites them to situate the burden-of-proof discussion within settled New York probate practice.
Matter of Pilon, 9 AD3d 771, 772 (3d Dept 2004): Central to the court’s holding. Pilon supplies two key presumptions: (1) due execution is presumed where execution is supervised by the drafting attorney; and (2) due execution is also presumed where the will is accompanied by a “self-executing affidavit,” rebuttable only by “positive proof” that formalities were not met. The court applies both presumptions and finds objectant offered no “positive proof.”
Matter of Rodriguez, 239 AD3d 1270, 1271 (4th Dept 2025): Invoked as a recent Fourth Department reiteration of the attorney-supervision presumption, supporting the court’s reliance on that presumption here.
Matter of Halpern, 76 AD3d 429, 431-432 (1st Dept 2010), affd 16 NY3d 777 (2011): Supports the same presumption framework; the Court of Appeals affirmance underscores its stability.
Matter of Korn, 25 AD3d 379, 379 (1st Dept 2006): Bolsters the “positive proof” standard required to overcome the self-proving affidavit presumption.
Matter of Collins, 60 NY2d 466, 469-471 (1983) and Matter of Ziele, 242 AD2d 576, 577 (2d Dept 1997): Used to reject the argument that a witness’s imperfect memory defeats probate. Under SCPA 1405(3), a will may be admitted where a witness forgets the execution, so long as the other witness and surrounding proof establish compliance. These cases anchor the court’s point: forgetfulness is not an “inherent inconsistency” and does not, by itself, rebut due execution.

B. Testamentary capacity: focus on the moment of execution; exclude unreliable hearsay

Matter of Alibrandi, 104 AD3d 1175, 1176 (4th Dept 2013) and Matter of Buck, 225 AD3d 1186, 1188 (4th Dept 2024): Provide the governing capacity test: whether the decedent was “lucid and rational at the time” the instruments were made. The court deploys these authorities to discount later anecdotes and to keep the inquiry pinned to June 30, 2021.
West Val. Fire Dist. No. 1 v Village of Springville, 294 AD2d 949, 950 (4th Dept 2002) and Unifund CCR Partners v Youngman, 89 AD3d 1377, 1378 (4th Dept 2011), lv denied 19 NY3d 803 (2012): Cited for foundational requirements to admit business records: a witness with personal knowledge of record-making practices must lay the foundation. They support exclusion of the chaplain notes as uncertified hearsay.
Matter of Joseph M.W. [Blake], 188 AD3d 1563, 1567 (4th Dept 2020), Iwasykiw v Starks, 179 AD3d 1485, 1487 (4th Dept 2020), and KG2, LLC v Weller, 105 AD3d 1414, 1415-1416 (4th Dept 2013): Reinforce that a record must be made under a business duty and as part of a routine, systematic practice; otherwise CPLR 4518(a) does not apply. These cases help the court conclude there was no showing the chaplain had a duty or that the notes were regularly relied upon as part of hospital business.
Deutsche Bank Natl. Trust Co. v Dennis, 181 AD3d 864, 869 (2d Dept 2020), quoting People v Kennedy, 68 NY2d 569, 580 (1986): Cited for the trustworthiness rationale behind the business-records exception—records must be created pursuant to a routine and relied upon in the business. This supports the conclusion that the chaplain notes lacked the indicia of reliability required for admission.

C. Undue influence: analytically independent from capacity; credibility-laden; summary judgment often inappropriate

Matter of Wang, 179 AD3d 418, 419 (1st Dept 2020), Matter of Johnson, 6 AD3d 859, 860-861 (3d Dept 2004), and Matter of Donovan, 47 AD2d 923, 924 (2d Dept 1975): Establish the doctrinal separation: testamentary capacity and undue influence are “separate and distinct.” The Fourth Department uses these cases to correct a common analytical drift—treating capacity findings as dispositive of influence claims.
Tirado v Miller, 75 AD3d 153, 158 (2d Dept 2010) (and cf. Burke v Arcadis G & M of N.Y. Architectural & Eng'g Servs., P.C., 149 AD3d 1514, 1517 [4th Dept 2017]; McGuire v McGuire, 29 AD3d 963, 965 [2d Dept 2006]): Addresses the procedural question whether a court may grant relief not precisely demanded, based on general relief clauses, where the relief is not dramatically different and the opponent is not prejudiced. The Fourth Department assumes arguendo that the Surrogate could reach undue influence procedurally—but holds the dismissal was still erroneous.
Mashreqbank PCS v Ahmed Hamad Al Gosaibi & Bros. Co., 101 AD3d 1, 17 (1st Dept 2012) (Andrias, J., dissenting), revd 23 NY3d 129 (2014): Cited “generally” to support the court’s conclusion that Surrogate’s Court erred by ignoring counsel’s concession that undue influence could not be resolved on summary judgment. The Fourth Department uses this reference to emphasize the importance of judicial restraint where a movant’s own position acknowledges triable issues and credibility disputes.
Matter of Rozof, 219 AD3d 1428, 1430 (2d Dept 2023), see generally Matter of Nealon, 104 AD3d 1088, 1089 (3d Dept 2013), affd 22 NY3d 1045 (2014), and Matter of Dibble, 243 AD3d 993, 995 (3d Dept 2025): Support the proposition that evidence of a confidential relationship and surrounding circumstances can create triable issues on undue influence, making summary judgment inappropriate. The court’s key move is that “petitioner's own proof” created such issues.

3.2 Legal Reasoning

A. Due execution (EPTL 3-2.1): presumptions + absence of “positive proof”

The Fourth Department treated due execution as a formal compliance question governed by EPTL 3-2.1. It recognized the proponent’s burden but emphasized that New York law supplies strong evidentiary shortcuts when (i) the drafting attorney supervises execution and (ii) the will includes a self-executing affidavit from the witnesses. Under Matter of Pilon, such a record creates presumptions of due execution that can be overcome only by “positive proof” of noncompliance.

Objectant’s main attack was witness memory: one attesting witness could not recall all details. The court held this does not amount to “positive proof” and is addressed directly by SCPA 1405(3), which, as explained in Matter of Collins, permits probate despite forgetfulness when other proof fills the gap. Thus, the will cleared EPTL 3-2.1 as a matter of law.

B. Testamentary capacity: the time-of-execution rule and evidentiary discipline

The court’s capacity analysis illustrates two recurring probate principles. First, capacity is assessed at the time of execution (Matter of Alibrandi; Matter of Buck), not by later confusion or isolated odd statements. Second, summary judgment records must be built with admissible evidence. The chaplain’s notes were excluded as hearsay because objectant did not satisfy CPLR 4518(a): no foundation witness established a business duty to make the notes or that they were made and relied upon as part of a routine practice (as discussed in West Val. Fire Dist. No. 1 v Village of Springville, Unifund CCR Partners v Youngman, Deutsche Bank Natl. Trust Co. v Dennis, and People v Kennedy).

Even if considered, the notes described the decedent as “lucid” and “organized in thought,” undercutting the very inference objectant sought. The court likewise discounted a later hospital conversation (the “Charles Lindbergh” remark) as too remote and too thin to raise an issue of fact about June 30, 2021. Finally, the court rejected the claim that decedent lacked capacity because counsel did not discuss asset values in detail at execution: the record showed decedent discussed specific Florida real estate disposition the morning of execution, and he had executed loan documents months earlier listing assets and liabilities.

C. Undue influence: a separate inquiry that turns on relationship dynamics and credibility

The decision’s most consequential teaching is the court’s insistence that undue influence cannot be disposed of merely because due execution and capacity are established. Relying on Matter of Wang, Matter of Johnson, and Matter of Donovan, the court reiterated that capacity and undue influence are distinct: a person may be competent yet susceptible to domination.

Procedurally, the Surrogate dismissed undue influence even though petitioner’s cross-motion was for “partial summary judgment” and—critically—petitioner’s counsel conceded the undue influence issue “cannot be determined on summary judgment” because material facts and credibility disputes required trial. The Fourth Department held it was error to ignore that concession, and further held that, on the merits, petitioner’s own proof revealed triable issues concerning a confidential relationship and undue influence (citing Matter of Rozof and related authorities).

This combination matters: the appellate court did not merely say “undue influence is fact-intensive.” It anchored reversal in (1) the doctrinal separation of undue influence from capacity, (2) counsel’s explicit acknowledgment of credibility disputes, and (3) record evidence sufficient to create triable issues. The result was reinstatement of the undue influence objection and vacatur of the probate decree.

3.3 Impact

Sharper boundary between capacity and undue influence at summary judgment. The opinion reinforces that proving lucidity and due execution does not, without more, extinguish an undue influence claim. Practically, proponents should expect undue influence to proceed to trial where the relationship facts are contested, even if capacity is strong.
Concessions and the “shape” of summary judgment motions matter. Where the proponent concedes undue influence turns on disputed facts and credibility, trial courts risk reversal by summarily dismissing anyway. The decision signals that appellate scrutiny will be especially strict when the moving papers themselves acknowledge triable issues.
Objectants must build admissible records. The treatment of the chaplain notes is a cautionary example: without CPLR 4518(a) foundation, seemingly relevant medical narrative entries may be unusable on summary judgment. Future litigants will likely invest more in proper certifications, foundation witnesses, or alternative admissible proof (e.g., deposition testimony, physician affidavits).
Probate practice: due execution remains difficult to defeat when attorney-supervised and self-proved. The opinion continues the trend that execution objections face an uphill climb in attorney-supervised signings with a self-executing affidavit, absent concrete “positive proof” of defective formalities.

4. Complex Concepts Simplified

Due execution (EPTL 3-2.1): The will must be signed properly and witnessed properly. New York requires specific formal steps. If a lawyer supervises the signing and the witnesses sign a sworn “self-executing affidavit,” courts generally presume the formalities were satisfied.
Self-executing affidavit (self-proving affidavit): A sworn statement by the witnesses, signed around the time of execution, confirming the required formalities occurred. It reduces the need for later witness testimony and creates a presumption of valid execution.
Testamentary capacity: The minimal mental ability to make a will: understanding one’s property in a general way, the natural objects of one’s bounty (family), and that one is making a will. The key time is the moment of signing—not before or after.
Undue influence: Pressure or manipulation that overcomes the decedent’s free will and causes a disposition the decedent would not otherwise make. A person can be mentally competent but still be unduly influenced.
Confidential relationship: A relationship of trust and reliance (often caregiver/ill person, agent/principal, or similar dynamics). Evidence of such a relationship can support an inference of undue influence when combined with suspicious circumstances.
Summary judgment: A pretrial ruling that no trial is needed because there are no material factual disputes. Undue influence claims often resist summary judgment because they commonly depend on credibility and circumstantial evidence.
Business records exception (CPLR 4518[a]): A rule allowing certain records to be admitted despite hearsay if made routinely, under a business duty, and relied upon in the business. Without proper certification or foundational testimony, records (or parts of records) may be excluded.

5. Conclusion

Matter of Estate of Mielty (Mielty) delivers a targeted but important procedural-substantive lesson in probate litigation: strong proof of due execution and testamentary capacity does not automatically defeat undue influence. The Fourth Department reaffirmed robust presumptions supporting attorney-supervised, self-proved wills, and it enforced evidentiary rigor in capacity challenges. Yet it also made clear that undue influence remains a distinct, credibility-heavy inquiry—one that should not be dismissed on summary judgment where the record, including the proponent’s own submissions and concessions, reveals triable issues about a confidential relationship and influence.
