Quick answer

A testator may institute an heir purely, or subject to a condition, a term, or a mode. A conditional institution makes the inheritance depend on an uncertain future event: a suspensive condition must happen before the heir acquires the right, while a resolutory condition ends the right if it happens. A modal institution (the mode) imposes on the heir a charge or obligation — the testator states the object of the institution, or applies the property to a particular purpose, or imposes a burden on the heir — but unlike a condition, the mode does not prevent the heir from acquiring the inheritance immediately; the heir gets it but must comply with the charge (and may be required to give security). A key limit: a condition or a mode cannot be imposed on the legitime; the legitime of compulsory heirs must be free from any condition, burden, or substitution, and any such imposition on the legitime is considered not written. Certain conditions are also void, such as an absolute condition not to marry (with exceptions) or conditions contrary to law or morals.

A testator does not have to leave property unconditionally. A will can attach a condition or a mode (charge) to a gift — but there are important limits.

Pure, Conditional, or Modal

An heir may be instituted:

Conditional Institution

A condition makes the inheritance depend on an uncertain future event:

With a suspensive condition, the property is held (often with administration) until the condition is fulfilled.

Modal Institution (the Mode)

A mode imposes on the heir a charge or obligation — the testator states the object of the institution, applies the property to a particular purpose, or imposes a burden. The crucial difference from a condition:

The old maxim: a condition suspends but does not compel; a mode compels but does not suspend.

The Legitime Cannot Be Burdened

A vital limit: no condition, term, mode, or substitution can be imposed on the legitime. The legitime of compulsory heirs must be free. Any condition or burden placed on the legitime is considered not written — the heir takes the legitime free and clear, ignoring the impermissible condition.

Void Conditions

Certain conditions are void, such as:

Frequently Asked Questions

Can a will impose a condition on an inheritance? Yes. A testator may institute an heir subject to a condition. A suspensive condition must happen before the heir acquires the right, while a resolutory condition ends the right if it happens.

What is a modal institution? One where the testator imposes a charge or obligation on the heir, states the object of the gift, or applies the property to a purpose. Unlike a condition, the mode does not prevent the heir from acquiring the inheritance immediately; the heir gets it but must comply with the charge.

What is the difference between a condition and a mode? A condition suspends acquisition until it is fulfilled but does not compel the heir to do anything. A mode does not suspend acquisition; the heir takes the property immediately but is compelled to comply with the charge.

Can a condition be imposed on the legitime? No. No condition, term, mode, or substitution can be imposed on the legitime. Any such imposition on the legitime is considered not written, and the compulsory heir takes the legitime free and clear.
