Landmark Puerto Rico Trust Cases You Should Know

The essential court decisions that define the boundaries of trust planning for Act 60 investors.

By Hans Riefkohl, Riefkohl Law • March 2026 • Part 9 of 12 in the Puerto Rico Trust Law Series

Introduction: Why Case Law Matters More Than You Think

Reading the Puerto Rico trust statute alone won’t make you an informed Act 60 investor. The real rules live in the decisions of Puerto Rico’s appellate courts—the cases that tested the statute’s limits, exposed its gray zones, and forced judges to reconcile civil law traditions with common law trust principles.

Every major trust case decided in Puerto Rico shapes how your trust will be interpreted, how your trustee can act, what protections actually work, and which planning strategies hold up under scrutiny. Whether you’re considering a trust for asset protection, wealth preservation, or multi-generational planning under Act 60, you need to know the landmark decisions that define the boundaries.

This article walks through the essential cases chronologically, showing how Puerto Rico trust law evolved—and why that evolution matters to you.

Part I: The Foundational Era (1950s–1980s)

Before Puerto Rico reformed its trust law with Act 219-2012, the courts spent decades developing a hybrid civil-common law framework. These early decisions established the DNA of Puerto Rico trusts.

The Landmark Case: Dávila v. Agrait, 116 D.P.R. 549 (1985)

Why This Case Matters: This is the foundational case every Puerto Rico trust lawyer cites. The Supreme Court of Puerto Rico established that a fideicomiso (Puerto Rico trust) can be created by will or during life (inter vivos). More importantly, Dávila confirmed that a trust can be valid even if the settlor retains extensive control and powers—a principle that would later underpin Act 60 trust planning.

The case held that trusts are subject to a strict priority: they are charged first against the tercio de mejora (the third of the estate a testator could use to favor some descendants), then against the free-disposition third. The trust itself cannot invade the legítima (forced heirship rights). This two-tier system meant that Puerto Rico trusts, unlike some common law trusts, could never fully disinherit spouse or children.

The Practical Takeaway: Your Act 60 trust must respect the forced heirship rights of your spouse and children. The trust structure protects only what the law allows you to dispose of freely.

Current status: Dávila remains good law and is frequently cited as the bedrock of modern Puerto Rico trust jurisprudence. Its principles have been reaffirmed and incorporated into later statutes and cases, with no subsequent cases overruling its core holdings.

Álvarez v. Secretario de Hacienda, 80 D.P.R. 16 (1957) – The Tax Law Watershed

This seminal case distinguished between trust validity and income attribution for tax purposes. A trust might be valid under succession law but still be taxed as a grantor trust if the settlor retained certain powers.

The Supreme Court applied the precursors to the “Clifford factors” (the common law test for grantor trust status) and held that the trustee, not the settlor, is the primary taxpayer on trust income—but only if the settlor truly relinquished control.

Why It Matters: Puerto Rico tax authorities don’t automatically respect trust entities the way mainland courts do. A trust that works under succession law might still be transparent for tax purposes if you keep too much power. This case proved that trusts require two separate analyses: legal validity and tax characterization.

Current status: Álvarez (1957) remains good law. Its reasoning laid the groundwork for Puerto Rico’s approach to grantor trust taxation and was further refined by subsequent cases and eventually by statute. No later court has overruled Álvarez.

Boscio v. Secretario de Hacienda, 84 D.P.R. 412 (1962) – Refining the Clifford Test

Building on Álvarez, Boscio applied a comprehensive nine-factor test to determine whether trust income belonged to the fiduciary or the settlor:

Trustee’s discretion over distributions
Settlor’s reserved rights (power to revoke, amend, control investments)
Whether income was accumulated or distributed
Whether income was used for settlor’s legal obligations
Source and nature of the transferred assets

The Key Holding: Accumulated income in a properly structured trust was NOT attributed to the settlor. But income used to satisfy the settlor’s legal obligations (child support, alimony, debt service) remained taxable to the settlor.

For Act 60 Investors: If your trust accumulates income and you don’t retain the right to demand distributions, the income belongs to the trust for tax purposes. If you retain the power to demand payments for your bills, the IRS will treat that income as yours.

Current status: Boscio is good law. Its nine-factor analysis remains influential in distinguishing genuine independent trusts from grantor-controlled arrangements. No subsequent decision has disapproved Boscio.

Clavell Rodríguez v. Registrador, 95 D.P.R. 348 (1967) – The Legítima Limit

This case settled a critical question: Can a fideicomiso burden the legítima at all?

The answer was no. A trust cannot encumber or limit the forced heirship rights of the settlor’s spouse and children. The only property that could go into a trust was what you could freely dispose of—mejora and free disposition property, not the estate reserved for heirs.

Why This Still Matters: This rule was partially superseded by Act 219-2012’s §3352c, which allows testamentary trusts to receive property subject to legítima, but with strict conditions. The principle remains: your Act 60 trust cannot bypass forced heirship. Understanding Clavell helps you understand why.

Current status: Clavell Rodríguez remains generally good law, but it has been partially superseded by Act 219-2012. Section 10 of Act 219-2012 (now 32 L.P.R.A. § 3352c) created a narrow exception: a testamentary trust may include a minor or incapacitated heir’s entire forced share (including legítima estricta and mejora) if that heir is the sole beneficiary of both income and principal. Puerto Rico’s Civil Code of 2020 further reformed succession law by eliminating the old three-part division of estates. As of 2020, the forced heirship share is generally one-half of the estate, and the mejora was abolished. However, a trust still cannot override the mandatory inheritance rights of protected heirs.

TOLIC (Transamerica Occidental Life) v. Rodríguez Febles, 170 D.P.R. 804 (2007) – Trusts Created by Holographic Will

In a dispute over life-insurance proceeds, the Supreme Court (2007 TSPR 67) held that a trust may be created by any type of will, and upheld a trust set out in the decedent’s holographic will.

Current status: Act 219-2012 still allows a trust to be created by will, and requires inter vivos trusts to be created by public deed (32 L.P.R.A. §3352). Today every trust constituted in Puerto Rico — testamentary trusts included — must also be recorded in the Special Registry of Trusts or it is void (Art. 5; Allio v. Santiago Chardón, 2026 TSPR 13).

Bonet Cardona v. Holahan, 181 D.P.R. 582 (2011) – Inter Vivos vs. Testamentary

In the final pre-2012 major case, the court clarified that inter vivos trust assets cannot be controlled by a will. If you transfer property into a trust during life, the will cannot later modify or revoke those assets. The trust is autonomous.

Relevance Today: This principle still governs. Assets you fund into your Act 60 trust are governed by the trust document, not your will. Your will cannot override or reshape the trust.

Current status: Bonet Cardona is good law, reinforced by Act 219-2012’s provisions. The 2012 Act explicitly states that a trust, once constituted, is an autonomous patrimony and its assets are no longer considered part of the settlor’s personal estate.

Part II: The 2012 Watershed – Ley 219-2012

In 2012, Puerto Rico’s legislature enacted Act 219, the modern Unified Puerto Rico Trust Act. This statute fundamentally transformed Puerto Rico trusts:

Juridical Personality: Post-2012 trusts are separate legal entities, not mere aggregates of property
Fiduciary Duties: The statute imposed comprehensive fiduciary duties (loyalty, prudence, impartiality, information rights)
Trust Modification: The statute provides mechanisms to modify irrevocable trusts through reserved rights under Article 10 (consent-based, judicial, cy pres, and trust protector mechanisms)—though notably without a decanting statute
Investment Standards: Prudent investor standard replaces older rules
Beneficiary Rights: Statutory rights to information, accounting, and challenge

The 2012 Act was not just a technical update—it rewrote the rules.

Act 219-2012 was amended in 2017 and again by Act 153-2026 (signed July 30, 2026; effective January 30, 2027). Act 153 rewrites Section 3352c (Article 10): no trust, revocable or irrevocable, may burden the forced heirs’ legítima, except a trust over the legítima for minor or incapacitated forced heirs named as the sole beneficiaries of income and principal; and the testator may place the freely disposable portion (replacing the old “tercio de mejora”) in trust, subject to Article 6’s duration limits.

Part III: Post-2012 Landmark Cases – The Modern Framework

Fideicomiso El Puente GNR (2024 TCA) – Pre-2012 Trusts Are Not Legal Persons

The Court of Appeals (KLCE202400164, Apr. 30, 2024) held that a trust created in 2009 under the former Civil Code has no juridical personality of its own and must act through a properly appointed trustee, and it dismissed the trust’s suit without prejudice. Trusts constituted under Law 219-2012 are different: since a 2017 amendment, Article 2 (32 LPRA §3351a) gives them “personalidad jurídica plena.”

Why It Matters: A trust constituted under Law 219-2012 is a legal entity in its own right. If your trust predates 2012, it sues and holds rights through its trustee — and the trustee’s appointment must be in order.

Rodríguez Toro v. Díaz López (2021 TCA) – Legítima Violations Are Fatal

This case voided a trust structure that attempted to shield $1.5 million in donations to second-marriage children from the forced heirship rights of first-marriage children.

The court’s holding was unambiguous: Trust irrevocability does not shield legítima violations. Even if the trust document says the trust is irrevocable, a court will void distributions that invade the forced share of legitimate heirs.

The Practical Impact: Your Act 60 trust cannot be used to disinherit a spouse or child below their statutory minimum. If the distributions would violate forced heirship law, the court will correct them—regardless of the trust’s terms.

Ramírez de Arellano v. Banco Popular (2025 TCA) – Investment Claims Still Pending

Beneficiaries alleged that the bank, as trustee of a 1991 family trust, invested more than $1 million in COFINA bonds contrary to the trust’s rating requirements. The Court of Appeals (KLAN202500530, July 18, 2025) affirmed a partial judgment and left the claims over the COFINA investment pending in the trial court; it made no finding of breach and imposed no liability. Because the trust predated Law 219-2012, the court applied the former Civil Code standard, under which a trustee is not liable for errors of judgment — only for willful neglect or manifest negligence (former Art. 862, 31 LPRA §2569).

The Practical Point: Trustee discretion is NOT discretion to ignore the trust instrument’s restrictions. The trustee cannot substitute its own market judgment for the terms of the trust. If the trust says “AAA-rated bonds only,” the trustee cannot invest in anything else, even if it thinks the lower-rated asset is a bargain.

For Your Trust: Make sure your trust instrument’s investment restrictions are clear, and your trustee understands they are binding, not advisory.

Álvarez Méndez v. Fideicomiso de Acciones (2021–ongoing) – Discretion Has Limits

This is perhaps the most important modern case for understanding trustee power. A 1949 trust holding 93% of a family corporation—with 16 pending causes of action—became the vehicle for testing whether a trustee’s discretion is truly unlimited.

The court held: “Authority to act does not equal authority to breach fiduciary duty.” Even if the trust document gives the trustee broad discretion, that discretion is circumscribed by the fiduciary duty of loyalty. The trustee cannot use the trust’s assets for the trustee’s benefit, even if the document doesn’t explicitly prohibit it.

Additionally, the court enforced beneficiary information rights under the statute—beneficiaries can demand an accounting and inspection of trust assets, regardless of whether the trust document tried to waive those rights.

Critical Lesson: A trustee’s discretion is powerful but not unlimited. Courts will police the trustee’s conduct to ensure it serves beneficiaries, not the trustee.

Fernández-Cuervo v. Palau Hartmann (2023 TCA) – Voting Trusts Have Different Rules

This case clarified that voting trusts—trusts created to control corporate voting rights—are governed primarily by Puerto Rico Corporation Law, not the Trust Act. The fiduciary duties differ, the modification rules differ, and the remedies differ.

The court also applied the actos propios doctrine (estoppel by conduct): a beneficiary who participated in trust actions cannot later challenge the trust’s validity.

For Family Business Owners: If you’re using a trust to control a family corporation and you’re also a beneficiary, be careful about your participation. Active involvement might bar you from later challenging the trust.

Valentín Pérez v. Valentín Pérez (2022 TCA) – Modification Requires Consent

A settlor attempted to add a new beneficiary to a trust unilaterally. The court held that modification of a trust requires the consent of ALL settlors (if there are multiple), not just one.

Implication: If you and a spouse create a joint trust, neither of you can later modify it alone—even if the trust document is silent on this point. The statutory default is that all settlors must agree.

Rivera Nieves v. Fideicomiso de la Familia (2021 TCA) – Settled Trust Disputes Stay Settled

A beneficiary who had already lost earlier suits over the family trust sued again to have it declared void or terminated and to obtain an accounting. The Court of Appeals (KLAN202100515, Nov. 30, 2021) affirmed dismissal with prejudice: the trust's validity and continuity and the trustees' administration had already been decided in prior final judgments (collateral estoppel), and the court upheld a $5,000 attorney's-fee award for temeridad.

The Rule: Once a court has finally decided a trust's validity or the trustees' administration, a beneficiary cannot relitigate it under a new label — and repeated suits can carry fee awards. (The duty to account is statutory; see Principle 4 below.)

Fideicomiso Irrevocable Rodríguez Bruno v. Aponte Cruz (2024 TCA) – Timing and Forced Heirship

A trust was created eight days before the 2020 Code came into effect, was funded with the settlor’s family home, and the settlor died about five months later — so the new Code governed his succession. The widow asserted her rights as a forced heir under the 2020 Civil Code, which eliminated the mejora and gave the surviving spouse a share of the legítima in ownership (under the 1930 Code the spouse's forced share was a usufruct).

The Court of Appeals (KLAN202400547, Aug. 27, 2024) set aside the trial court’s summary judgment for the trust and remanded for an inventory and partition of the estate to determine whether the gift of the home invaded the widow’s legítima — any excess to be cured by reduction, not annulment. This case reinforces that trusts cannot circumvent spousal forced heirship, no matter how quickly they are set up or how long the settlor lives thereafter.

Fideicomiso Caro Delui (2012 TCA) – Separate vs. Community Property

A trust was funded with separate property and held through a divorce proceeding. The court held that separate property placed in a trust remains protected—the trust shields the asset from community property division.

Caveat: Community property contributed to the trust is NOT protected. If a spouse uses community funds to contribute to a trust, those assets are reachable in a divorce settlement.

Crespo Rivera v. Crespo Rivera (2024 TCA) – Removal Must Be Formal

A trustee was removed by letter—an informal removal. All subsequent trust actions taken by the purported trustee were voided. The court held that removal of a trustee must be accomplished by public deed, not informal notice.

Practical Lesson: Trustee removal is a formal legal action. If you need to remove a trustee, do it through proper legal channels, not an email or letter.

Part IV: Ten Legal Principles Every Act 60 Investor Should Know

Based on the case law above, here are the ten principles that should shape your trust planning:

1. Trust Irrevocability Does NOT Shield Legítima Violations

Your Act 60 trust cannot be used to disinherit a spouse or child below their statutory forced share. If distributions violate forced heirship law, courts will correct them regardless of irrevocability. (Rodríguez Toro)

2. Trustees Must Strictly Comply with Instrument Restrictions

The trustee’s discretion, however broad, is limited by the terms of the trust document. If the trust says “no investments below AAA-rated,” the trustee cannot invest in lower-rated assets, period. (Ramírez de Arellano)

3. Post-2012 Trusts Have Full Juridical Personality

Your Act 60 trust is a legal entity. It can sue and be sued in its own name, hold property in its own name, and assert independent legal claims. (El Puente)

4. Beneficiaries Have Statutory Rights to Accounting

Article 27 of the Trust Act (32 LPRA §3352t) requires the trustee to give beneficiaries, on request and with reasonable frequency, complete and accurate information about the trust property and to let them inspect the property, accounts and records; to keep clear and exact accounts; and to render accounts as the trust deed provides or, if it is silent, at least once a year and when the trust ends. A trustee who keeps no accounts, or unclear ones, is liable for any resulting loss.

5. Modification Requires All Settlors’ Consent

If multiple settlors created the trust, all must agree to modify it. One settlor cannot unilaterally add beneficiaries or change terms. (Valentín Pérez)

6. Asset Protection Is Qualified—Some Distributions Are Reachable

A trust provides protection, but distributions taken out are vulnerable. Once money leaves the trust and enters your personal account, it loses some protection.

7. Separate Property Trust Funding Protects in Divorce; Community Property Does Not

Assets you place in a trust using your separate property remain protected in a divorce. Assets funded with community property may be reachable by a divorcing spouse. (Caro Delui)

8. Voting Trusts Have Different Rules from Ordinary Trusts

If your trust controls corporate voting rights, different rules apply. Consult experienced Puerto Rico corporate counsel, not just trust law. (Fernández-Cuervo)

9. Successor Trustees Inherit Only Their Own Liability

A successor trustee is not automatically liable for breaches by the predecessor. Each trustee is responsible only for breaches during their own tenure. (Ramírez de Arellano)

10. Trustee Authority Does Not Equal Authority to Breach Fiduciary Duty

Even if the trust document gives the trustee broad discretion, that power is limited by the fiduciary duty of loyalty. The trustee cannot exploit the trust for personal benefit. (Álvarez Méndez)

Part V: The Historical Arc – How We Got Here

The evolution of Puerto Rico trust law tells a story:

1950s–1960s: The Tax Foundation Era
Puerto Rico courts first grappled with trusts through the lens of tax law. Cases like Álvarez and Boscio established that Puerto Rico would apply a Clifford-factor approach, blending common law tax principles with civil law trust concepts.

1967–1990s: Succession and Property Phase
Cases like Clavell Rodríguez clarified the boundaries: trusts could not invade forced heirship, but they could accomplish significant planning within those limits. The decade saw trusts become a standard estate planning tool.

2005–2012: Pre-Reform Sophistication
As wealth management grew in Puerto Rico, trusts became more complex. Cases like TOLIC and Bonet Cardona addressed multi-jurisdictional issues and the interaction of inter vivos and testamentary instruments.

2012–Present: The Modern Statutory Framework
Act 219-2012 rewrote the rules, codifying best practices and extending fiduciary duties. Post-2012 cases like Ramírez de Arellano, Álvarez Méndez, and Rodríguez Toro have refined the statute and enforced its protective principles.

Part VI: What This Means for Your Act 60 Trust

As a prospective Act 60 IRI (Individual Investor), you should internalize these lessons:

1. Your Trust Is Not Bulletproof

A trust provides real benefits—creditor protection, privacy, professional management, multi-generational planning. But it is not a magic bullet. Courts will enforce the forced heirship rules, police trustee conduct, and protect beneficiary statutory rights. Plan accordingly.

2. Drafting Matters

The trust document must be precise. Vague language about investment authority, trustee discretion, or modification rights will be narrowly construed against the trustee. Work with an experienced Puerto Rico trust attorney—not a mainland lawyer.

3. Trustee Selection Is Critical

Your trustee will have power to invest, distribute, and manage your assets for decades. The case law shows that courts will hold trustees accountable for breaching the trust document or fiduciary duties. Choose your trustee carefully.

4. Act 60 Tax Benefits + Trust Protections = Strategy

The real power of an Act 60 trust is the combination: the generous tax benefits of Act 60 combined with the privacy and creditor protection of a Puerto Rico trust. But the trust structure must comply with the rules—both the statute and the case law.

5. Keep Records and Account Regularly

The case law shows that beneficiaries have statutory rights to accounting and information. Transparent record-keeping protects the trustee and prevents disputes. If you’re a trustee, maintain meticulous accounts.

6. Respect Forced Heirship

The single most consistent theme in Puerto Rico trust law is this: trusts cannot bypass forced heirship. Your Act 60 trust will protect your wealth, but only within the bounds of what the law allows you to dispose of freely.

Conclusion: Case Law as Your Roadmap

Puerto Rico trust law is not a static collection of code sections. It is a living, evolving framework shaped by decades of case law. The landmark cases in this article—from Dávila to Ramírez de Arellano—are not historical curiosities. They are the rules that will govern your trust.

Before you commit to an Act 60 trust structure, make sure you understand the case law. Know what courts have decided about trustee discretion, beneficiary rights, legítima protection, and creditor claims. The statute sets the stage, but the cases determine the outcome.

An informed Act 60 investor is an investor who reads not just the trust statute, but the decisions interpreting it. That is the surest path to a trust that does what you intend and withstands judicial scrutiny.
