A more thorough explanation:

A modal legacy is a type of gift given through a will, usually in the form of personal property or money. It is similar to a bequest or devise, but with specific conditions attached to it.

• Absolute Legacy: A legacy given without any conditions and intended to be received immediately.
• Conditional Legacy: A legacy that will only take effect or be defeated based on the occurrence or non-occurrence of a specific event.
• Contingent Legacy: A legacy that depends on an uncertain event and has not yet vested. For example, a legacy given to a grandchild "if they attain the age of 21."
• Demonstrative Legacy: A legacy paid from a specific source, but if that source does not have enough money, the remaining amount is taken from the estate's general assets.
• Additional Legacy: A second legacy given to a legatee in the same will or codicil as another legacy. It is supplementary and not considered a repeated expression of the same gift.
• Alternate Legacy: A legacy that allows the legatee to choose one of two or more items.

For example, if a person's will states that their grandchild will receive $10,000 when they turn 25, this is a conditional legacy because it is dependent on the grandchild reaching that age. If the will states that the grandchild will receive $10,000 from the sale of a specific piece of property, this is a demonstrative legacy because it is paid from a specific source.
