Union Bank of the Philippines v. Tantoco

G.R. No. E-02776 · July 7, 2026THIRD DIVISION · Ponente: Associate Justice Henri Jean Paul B. Inting

CASE DOCTRINE. A creditor — even a bank holding a deceased depositor's own accounts — cannot unilaterally offset what it is owed against the decedent's deposits. It must file its claim before the probate or intestate court, like any other creditor, and cannot “skip the line” by appropriating estate assets on its own. A contractual clause triggered by the depositor's death does not excuse compliance with the Rules of Court — whether offsetting is proper is for the probate court, not the creditor, to decide.

Why this case matters. This is the clearest, most current Supreme Court guidance on how Rule 86 (Claims Against the Estate) interacts with a contractual “set-off on death” clause — a recurring bar-exam pattern that blends Civil Law (compensation, agency extinguished by death) with Remedial Law (claims against the estate, the limits of probate jurisdiction).

Money owed to a bank does not disappear when the debtor dies — but neither does the depositor's money become fair game for the bank's own immediate self-help. This case draws the line between what a creditor may do on its own, and what it must instead bring to the probate court.

DENIED

Petition denied — CA affirmed

I. The parties

Role	Who
Petitioner	Union Bank of the Philippines — held several of the decedent's deposit accounts and was also one of his creditors
Respondents	Bernardina Arroyo Tantoco and Alicia Rita M. Arroyo — the duly appointed joint administrators of the estate of Ignacio T. Arroyo
Decedent	Ignacio T. Arroyo, died January 26, 2012
Proceeding below	Intestate settlement, RTC Branch 98, Quezon City — SPC Case No. R-QZN-15-01411

II. The facts

During the intestate proceedings, the administrators obtained a court order compelling Union Bank to produce statements of account for the decedent's bank accounts. Reviewing them, administrator Alicia Rita (“Aleli”) Arroyo found several transactions posted after Ignacio's death. She moved to compel the bank to explain those withdrawals and to produce email exchanges between bank officers and a lawyer referred to as “Atty. Fe,” who had ordered certain withdrawals.

Union Bank resisted on procedural grounds — the request lacked specificity, some emails were privileged, and records beyond five years no longer existed under BSP retention rules — and offered three explanations for the withdrawals themselves: settling the decedent's own obligations to the bank, a survivorship agreement, and administrator-authorized payments of estate taxes. The RTC ordered the bank to explain and produce the records anyway; the Court of Appeals affirmed. Union Bank elevated the matter to the Supreme Court, arguing a probate court's authority is limited to inventory-taking, and that scrutinizing its explanations turned the proceeding into an improper adversarial inquiry that belonged in a separate civil case.

III. The probate court's power to compel an accounting

The Court held the RTC's orders were a proper exercise of probate jurisdiction. That jurisdiction is generally limited, but it rests expressly on:

Rule 87, Sec. 6 — lets the court, on complaint of an administrator, heir, creditor, or other interested person, cite anyone suspected of concealing, embezzling, or conveying away estate property (or holding documents proving the decedent's rights), and examine that person under oath. Refusal is punishable as contempt.

Rule 87, Sec. 7 — lets the court, on complaint of the administrator, cite anyone entrusted with estate property and compel a full accounting under oath of that property and what was done with it.

Rule 87, Sec. 2 — empowers the administrator to bring actions for the recovery or protection of the deceased's property or rights.

This is the part of the decision actually certified for review: whether the RTC exceeded its authority by ordering Union Bank to explain itself. The Court said no — a bank holding a deceased client's accounts, resisting an accounting, is exactly who Sections 6 and 7 are written for. The Court added that a probate court, though its jurisdiction is generally limited, may provisionally pass upon title and ownership of disputed property for the specific purpose of deciding whether it belongs in the estate's inventory (citing Estipona v. Estate of Anacleto Aquino and Lorna Fe Espinosa, 911 Phil. 245, 262 (2021) — a different “Estipona” case than the plea-bargaining one of the same surname).

IV. The survivorship-agreement defense

On the bank's claim that some withdrawals were covered by a survivorship agreement over a joint account, the Court turned to settled doctrine:

Survivorship agreements over joint accounts are generally valid aleatory contracts, but may be set aside if shown to be a mere cloak for an inofficious donation, a device to defraud creditors, or a way to defeat a compulsory heir's legitime. Citing Vitug v. Court of Appeals, 262 Phil. 830 (1990)

A bank's bare assertion that a survivorship agreement exists is not, by itself, conclusive — the probate court may require more before excluding the funds from the inventory.

V. The offsetting problem

Separately from the accounting issue, the Court flagged something the bank had done entirely on its own initiative — applying the decedent's deposits against his unpaid debts to the bank, without any court involvement:

“It is also worth noting that petitioner unilaterally offset Ignacio's alleged liabilities against his deposits. Such action effectively circumvents the rules governing claims against the estate. As a creditor, petitioner is required to file its claims before the probate court and cannot simply ‘skip the line’ so to speak by appropriating estate assets to satisfy its claims. Regardless of any default clause triggered by the depositor’s death, such stipulation does not dispense with compliance with the Rules of Court. Neither does it justify petitioner’s refusal to comply with the directives of the RTC on the ground that doing so would convert the proceeding into an adversarial one. It is well within the jurisdiction of the probate court to determine whether such offsetting is proper.” Decision, pp. 7–8, citing Rules of Court, Rule 86, Sec. 5

Two things worth being precise about. First, this passage is not the formally certified issue — it supports the Court's broader reasoning for why the RTC was right to keep scrutinizing the bank's conduct. A very technical reading could call it persuasive rather than squarely-the-holding on offsetting in isolation; in practice, it is unambiguous Supreme Court language, in a Decision, addressing a default/offset clause head-on. Second, the Court does not say offsetting-with-consent is always void — it says the probate court decides whether it is proper. Either way, the practical effect is the same: the bank does not get to make that call for itself.

VI. The disposition

“ACCORDINGLY, the Petition for Review on Certiorari is hereby DENIED. The Decision dated December 26, 2024, and the Resolution dated August 28, 2025, of the Court of Appeals in CA-G.R. SP No. 167525 are AFFIRMED. SO ORDERED.” Union Bank of the Philippines v. Tantoco, G.R. No. E-02776, July 7, 2026

VII. Likely exam angles

Q1Can a bank apply a deceased depositor's account balance to the depositor's unpaid loan without going to the probate court first?

ANot safely, under this case's reasoning. Even a signed clause authorizing it does not excuse the bank from filing its claim with the probate court, which alone decides whether the offset is proper.

Q2Does a survivorship agreement automatically keep joint-account funds out of the decedent's estate?

ANo. It is a valid aleatory contract as a general rule, but the probate court may require proof that it is not a cloak for fraud, an inofficious donation, or a device to defeat a compulsory heir's legitime, per Vitug v. CA.

Q3What can a probate court do, despite its generally limited jurisdiction?

AIt may provisionally pass upon title or ownership of disputed property to decide whether it belongs in the estate's inventory (Rule 87; Estipona v. Estate of Aquino), and it may cite and compel an accounting, under oath, from anyone suspected of concealing estate property or entrusted with it (Rule 87, Secs. 6–7).

VIII. Bar takeaways

1. A creditor's claim against a decedent — even a bank's claim against its own depositor — must be filed with the probate or intestate court under Rule 86, not self-collected.
2. A contractual clause triggered by the depositor's death does not dispense with compliance with the Rules of Court.
3. Probate courts have generally limited jurisdiction, but may provisionally determine title or ownership of disputed property to decide inventory inclusion (Rule 87; Estipona v. Estate of Aquino).
4. Rule 87, Secs. 6 and 7 let a probate court compel anyone suspected of concealing estate property, or entrusted with it, to explain and account for it under oath.
5. Survivorship agreements are valid aleatory contracts as a rule, but may be struck down as a cloak for fraud, an inofficious donation, or defeating a legitime (Vitug v. CA).

IX. Authorities

Authority	Point it supports
Rules of Court, Rule 86, Sec. 5	Claims against the estate must be filed within the notice period; basis for the “cannot skip the line” ruling on offsetting
Rules of Court, Rule 87, Secs. 2, 6, 7	Probate court's power to compel an accounting from a suspected concealer or custodian of estate property; administrator's power to sue for estate property
Vitug v. Court of Appeals, 262 Phil. 830 (1990)	Survivorship agreements are generally valid, but may be impugned as a cloak for fraud, an inofficious donation, or defeating a legitime
Estipona v. Estate of Anacleto Aquino and Lorna Fe Espinosa, 911 Phil. 245 (2021)	Probate courts may provisionally pass on title/ownership to decide inventory inclusion

Even your own bank has to get in line.

A depositor's death doesn't hand a creditor — bank or otherwise — a shortcut around the estate settlement process.

Careful in the comments. Don't post this as “banks can never freeze or apply a deceased client's funds.” The holding is about unilateral self-help offsetting without the probate court's involvement — a bank may still assert its claim, including as a secured or preferred creditor, through the estate settlement process itself.
