How Forced Heirship Affects Your Estate Plan in Puerto Rico

If you are accustomed to estate planning in the mainland United States, Puerto Rico's forced heirship rules will challenge your assumptions. In most states, you can leave your assets to whoever you want. You can disinherit a child, leave everything to a charity, or divide your estate any way you see fit.

Not in Puerto Rico.

Under the Puerto Rico Civil Code (Ley 55-2020), a substantial portion of your estate is reserved by law for certain family members — typically your children. This mandatory inheritance system, called the legítima, limits your freedom to distribute your estate. And if your estate plan does not account for it, your heirs may end up in court.

What Is the Legítima?

The legítima is the portion of a deceased person's estate that Puerto Rico law reserves for "forced heirs" (herederos forzosos). You cannot dispose of this portion freely — it must go to the people the law designates, regardless of what your will says.

Under the current Civil Code (which took effect in 2020), your estate is divided into three parts:

The Legítima Estricta (One-Third)

This one-third of your estate is divided equally among all your forced heirs. If you have three children, each receives one-ninth of your total estate from this portion. You have no discretion over how this third is allocated — it is divided by operation of law.

The Mejora (One-Third)

This one-third must also go to your forced heirs, but you have discretion over how it is distributed among them. You could give the entire mejora to one child and nothing to another, as long as every recipient is a forced heir. This allows you to favor certain heirs over others while keeping the assets within the class of forced heirs.

The Libre Disposición (One-Third)

This is the only third you can leave to anyone you choose — a spouse, a friend, a charity, a business partner, or anyone else. This is the portion of your estate where you have full testamentary freedom.

Who Are the Forced Heirs?

Under the 2020 Civil Code, the primary forced heirs are:

Children and descendants. Your children are the first-priority forced heirs. If a child predeceases you, that child's descendants (your grandchildren) step into their place by right of representation.

Parents and ascendants. If you die without children or descendants, your parents become forced heirs. If your parents have predeceased you, grandparents may qualify in some circumstances.

Surviving spouse. The surviving spouse has a right to a usufruct (a life estate or use-right) over a portion of the estate, but is not a forced heir in the same sense as children. The spouse's rights interact with, but do not replace, the children's legítima.

One important change under the 2020 Code: the forced heirship share was reduced from two-thirds of the estate (under the prior code) to the current structure. Prior to 2020, the legítima estricta and mejora together consumed two-thirds, leaving only one-third free. The 2020 Code maintained this general structure but clarified several provisions regarding how the shares are calculated and distributed.

Why Forced Heirship Creates Problems for Mainland Transplants

If you moved to Puerto Rico from a common law state, your existing estate plan almost certainly does not account for forced heirship. Here are the most common conflicts:

"Everything to my spouse" plans

Many mainland couples have mirror wills or revocable trusts that leave everything to the surviving spouse, then to children equally upon the second death. In Puerto Rico, this does not work as written if you have children. Your children are entitled to their legítima at your death — they do not have to wait until the surviving spouse dies. A will that attempts to leave everything to a spouse can be partially invalidated.

Disinheritance

On the mainland, disinheriting a child is generally straightforward — you state in your will that you are intentionally making no provision for that person, and it sticks. In Puerto Rico, disinheritance of a forced heir is only permitted for specific, enumerated grounds (such as a child who has attempted to kill the parent or has been convicted of certain serious crimes against the parent). Personal disagreements, estrangement, or lifestyle disapproval are not sufficient grounds.

Unequal distributions

If you want to leave 80% of your estate to one child and 20% to another, Puerto Rico law limits how unequal the distribution can be. The legítima estricta must be divided equally. You can use the mejora to favor one child, but you cannot entirely exclude another forced heir without meeting the strict disinheritance grounds.

Trust-based plans that ignore the legítima

A revocable trust that distributes assets entirely to a surviving spouse — or to certain children while excluding others — may be challenged by forced heirs. The trust does not override the legítima simply because assets are titled in the trust's name.

Planning Strategies That Work Within Forced Heirship

Forced heirship limits your options, but it does not eliminate planning. Several strategies can help you achieve your goals while respecting the legal framework:

1. Use the Mejora Strategically

The mejora gives you meaningful discretion. If you want to favor one child — for example, a child who is actively involved in the family business, or a child with special needs — you can direct the entire mejora third to that child. Combined with the libre disposición third, you can direct up to two-thirds of your estate to a single forced heir while satisfying everyone's legítima estricta.

2. Lifetime Giving

Assets transferred during your lifetime — through inter vivos gifts — reduce the size of your estate at death. However, Puerto Rico law includes "collation" provisions that may require certain lifetime gifts to be brought back into the estate for purposes of calculating the legítima. The rules on which gifts are subject to collation are technical, and the timing and structure of gifts matters significantly.

This is an area where professional guidance is essential. A poorly structured lifetime gift program can create more problems than it solves.

3. Irrevocable Trusts Under Law 219-2012

Puerto Rico Law 219-2012 provides a modern trust framework that can be used in conjunction with forced heirship planning. An irrevocable trust, properly structured, can:

• Provide lifetime income to a surviving spouse while preserving the principal for forced heirs

• Manage assets professionally for minor children or heirs who are not ready to inherit directly

• Protect assets from creditors while satisfying forced heirship obligations

• Enable multi-generational planning through dynasty trust provisions

The key constraint: the trust must be structured to satisfy the legítima. A trust that attempts to circumvent forced heirship — for example, by locking up all assets for 30 years while providing only discretionary distributions to forced heirs — can be challenged.

The best approach is to design the trust so that forced heirs' rights are built into the trust terms from the outset. For example, the trust can provide that upon the settlor's death, each forced heir's legítima estricta share is distributed outright (or into individual sub-trusts), while the mejora and libre disposición portions are managed according to the settlor's wishes.

4. Dual-Will Architecture

If you own assets in multiple jurisdictions — which is common for mainland transplants and Act 60 decree holders — consider a dual-will structure. One will governs your Puerto Rico assets (and complies with forced heirship), while a separate will governs your assets in other jurisdictions (where you may have more flexibility). This avoids subjecting non-Puerto Rico assets to forced heirship rules that may not apply to them.

This structure requires careful coordination. The wills must not contradict each other, and the governing law provisions must be properly drafted to ensure each will controls only the assets it is intended to cover.

5. Life Insurance

Life insurance proceeds are generally not part of the legítima calculation, provided the policy is properly structured. This makes life insurance a valuable tool for providing for a surviving spouse or a non-heir beneficiary without reducing the forced heirs' share of the estate.

For example, if you want your spouse to receive a larger portion than the estate allows after satisfying the legítima, a life insurance policy payable to the spouse can supplement what they receive from the estate.

The 2020 Civil Code Changes: What You Need to Know

The Ley 55-2020 (Puerto Rico Civil Code) introduced several changes relevant to forced heirship:

• Clarified calculation methods for the legítima in the context of trusts and other non-probate transfers

• Modernized collation rules regarding lifetime gifts and how they interact with forced heirship calculations

• Updated the surviving spouse's rights, clarifying the usufruct provisions and how they interact with the children's legítima

• Preserved the fundamental structure of forced heirship while adjusting some procedural aspects

If your estate plan was drafted before 2020 under the prior Civil Code, it should be reviewed to ensure compliance with the current provisions. The core concepts are the same, but the details matter.

Common Questions

Can I avoid forced heirship by moving my assets out of Puerto Rico?
Possibly, for assets located outside Puerto Rico. The application of forced heirship to non-Puerto Rico assets depends on domicile and choice-of-law analysis. This is one reason dual-will structures exist — to separate assets subject to different legal regimes.

My mainland trust says it's governed by Delaware law. Does forced heirship still apply?
It depends on the nature of the assets, where they are located, and your domicile at death. A choice-of-law provision in a trust is one factor, but Puerto Rico courts may apply forced heirship to Puerto Rico-situs assets regardless of what the trust instrument says. Do not assume a governing law clause overrides local mandatory inheritance rules.

Can my children waive their legítima?
Puerto Rico law does not permit prospective waiver of the legítima — a forced heir cannot agree in advance to give up their inheritance rights. Post-death renunciation is possible but involves its own legal requirements.

What if I only have one child?
The structure is the same. Your one child receives the entire legítima estricta (one-third of your estate) and you can direct the mejora to that child as well, or to that child's descendants. The libre disposición remains yours to allocate freely.

The Bottom Line

Forced heirship is not an obstacle to be circumvented — it is a feature of Puerto Rico law that must be incorporated into your estate plan. The attorneys, trustees, and judges who work within this system expect to see plans that respect the legítima while using the available tools — the mejora, irrevocable trusts, life insurance, and careful structuring — to achieve the client's goals.

If your estate plan was created on the mainland, or if it has not been updated since the 2020 Civil Code, it likely does not account for these rules. The cost of revising it now is modest compared to the litigation costs your heirs will face if the plan fails.
