Legal Definitions - fideicommissary heir

A fideicommissary heir is a legal term primarily used in civil law systems (such as those influenced by Roman-Dutch law) to describe a person who is designated to inherit property or assets *after* an initial heir has held them for a specific period or until a particular condition is met. In this arrangement, known as a fideicommissum, the initial heir (often called the "fiduciary heir") receives the property with a limited right of ownership, meaning they can use and enjoy it but cannot freely sell, mortgage, or dispose of it. The property is essentially held in trust for the ultimate benefit of the fideicommissary heir.

Here are some examples to illustrate this concept:

• Family Home Succession: Imagine a will where a grandmother leaves her beloved family home to her son, David, for his lifetime. However, the will explicitly states that upon David's death, the house must then pass to her granddaughter, Emily. In this scenario, David is the initial (fiduciary) heir, and Emily is the fideicommissary heir. She is the ultimate beneficiary who will inherit the property after her father's temporary ownership concludes.

• Preserving an Art Collection: A renowned art collector's will stipulates that his valuable collection of paintings should go to his wife, Sarah, for her enjoyment and use during her lifetime. The will further specifies that upon Sarah's passing, the entire collection must be donated to the local City Museum. Here, Sarah is the fiduciary heir, holding the collection for her lifetime, and the City Museum is the fideicommissary heir, destined to receive the collection after Sarah's death.

• Conditional Farm Inheritance: A farmer's will leaves his productive agricultural land to his eldest son, Mark, with the condition that Mark must manage and live on the farm. The will also states that if Mark dies without any children, the farm must then pass to his younger sister, Lisa. In this case, Mark is the fiduciary heir, and Lisa is the fideicommissary heir, whose right to the farm vests if the specific condition (Mark dying without children) is met, ensuring the farm remains within the broader family line.
