For most of the United States, transferring wealth involves navigating a relatively consistent landscape of common law and the Uniform Trust Code. But journey to the bayou, and you find yourself in a state of legal anomalies: Louisiana.
As the only U.S. state operating under a Civil Law system, rooted in French and Spanish traditions, particularly the Napoleonic Code, Louisiana’s approach to wealth transfer is fundamentally different. For high-net-worth individuals, entrepreneurs, and anyone with property in Louisiana, failing to recognize these unique laws can derail a carefully structured estate plan, leading to unintended distributions and costly legal battles.
These differences range from foundational to semantic. Here are the three critical differences between Louisiana estate law and the rest of the nation.
1. The Legal Foundation: Civil Law vs. Common Law
The fundamental distinction between Louisiana and the other 50 legal jurisdictions in the United States is the legal framework itself. The differences between civil law and common law are not merely semantic; they dictate how documents are drafted and interpreted.
The common law system prevalent in most of the United States is largely uncodified. While state and local statutes address some areas of our affairs, the majority of common law comes from legal precedent created by judicial decisions. Accordingly, judges hold tremendous authority in shaping the legal landscape across the U.S.
Civil law systems, however, are governed by robust coded rules and statutes that govern public and private life. A judge’s role in a civil law system is to refer to and interpret the relevant statutes when resolving disputes.
Louisiana’s legal code brings with it distinctive concepts that do not appear in common law jurisdictions. For example, Louisiana’s concept of usufruct grants a person the right to use and benefit from property, like living in a home or collecting rent, without owning the underlying asset, which is held by the “naked owner.” This concept is often used to provide for a surviving spouse without giving them outright ownership.
2. The Great Restriction: Forced Heirship and the “Legitime”
The most startling difference in Louisiana estate planning is the principle of “forced heirship.”
In almost every other state, competent adults have near-total freedom to disinherit their adult children. Louisiana is the exception. Forced heirship mandates that a certain portion of a decedent’s estate, known as the legitime, must be reserved for certain designated heirs, regardless of the testator’s wishes expressed in a will or revocable trust.
Who is a Forced Heir?
Under current Louisiana law, a forced heir generally includes:
- Any child who is twenty-three (23) years of age or younger at the time of the parent’s death.
- Any child of any age who, due to mental or physical condition, is permanently incapable of caring for their person or administering their estate.
- In limited circumstances, a grandchild may qualify if their parent (the decedent’s child) predeceased the decedent, and other specific conditions are met.
What is the Forced Portion?
The size of the legitime varies based on the number of forced heirs:
- One forced heir: They are entitled to one-quarter (1/4) of the estate.
- Two or more forced heirs: They are collectively entitled to one-half (1/2) of the estate, to be divided equally.
The forced heir’s portion (legitime) is capped at the intestate share that descendant would have inherited under Louisiana’s intestacy laws. For instance, if a decedent has five children, and only one child qualifies as a forced heir, that child’s maximum share would be the one-fifth intestate share, not one-quarter under the forced heirship rules.
Historical Significance and Continuing Impact
The power of this law is perhaps best illustrated by the decades-long legal and political fight to limit it. Throughout the 1980s and 1990s, powerful lobbying groups and wealthy individuals campaigned to repeal the law, arguing it violated property rights and individual freedom.
In a landmark decision, the Louisiana Supreme Court’s ruling in Succession of Lauga showcased the historical weight of the Civil Law tradition. The case involved an attempt by a father to leave his entire estate to just one of his three adult sons. The two disinherited sons successfully challenged the will, arguing that a legislative act attempting to limit forced heirship to children under the age of 24 was unconstitutional because it violated the fundamental promise of the state’s constitution to protect the right of forced heirship for all descendants [1].
While the law has since been successfully reformed to its current, more restrictive definition, the case highlights a core principle: in Louisiana, the state’s duty to protect vulnerable family members can supersede an individual’s desire for complete testamentary freedom. A properly drafted estate plan must explicitly address the legitime, or face the risk of being overturned in court [2].
3. The Toolset: The Louisiana Trust Code
Trusts are essential tools for wealth management. However, even these common planning devices are treated uniquely in Louisiana.
The Louisiana Trust Code is distinct from the Uniform Trust Code adopted by most other states. Key differences include:
- Restrictive Formalities: Louisiana imposes strict formalities on trust creation and structure. Generic trust forms designed for Common Law jurisdictions often fail to meet these requirements, risking invalidation.
- Modification and Termination: Louisiana trusts can be more restrictive in how and when they can be modified or terminated after creation. Beneficiaries who are entitled to principal have a vested interest in the trust upon creation, restricting disposition options and other flexibility that might be available in common law states.
- Duration: While Louisiana has moved toward accepting perpetual trusts, dynasty trusts are much less common in Louisiana than other states. Historical restrictions around trust duration mean that planning must be executed with an attorney who is deeply familiar with the nuances of the state’s specific trust codes [3].
