A more thorough explanation:

An inofficious will is a type of will that does not distribute the property of the deceased person to their natural heirs. This means that the will may deprive the heirs of a portion of the estate that they would normally be entitled to by law.

For example, if a person creates a will that leaves all of their property to a friend instead of their children, who would normally inherit the property, this would be considered an inofficious will.

Inofficious wills are also known as unofficious wills. They are different from officious wills, which distribute the property to the testator's family and reserve a portion for their children and other natural heirs.

Overall, an inofficious will is a type of will that goes against the normal rules of inheritance and may not be considered valid in certain situations.
