A will is a legal document executed by a single person, known as the testator, by which the testator disposes of their property to one or more people.

The will, before a notary, with substitution is a legal act by which the testator bequeaths his assets to one or more persons, with the obligation for these persons to return the assets that he still possesses after a certain period of time to a third party.

The testamentary trust is a document by which a person, known as the testator, transfers their assets upon death to another estate that they establish.
