A more thorough explanation:

Natural succession refers to the process of succession between natural persons, such as the passing of property or rights from an ancestor to their descendants upon their death. This is in contrast to other types of succession, such as testamentary succession (where rights or property are passed through a will) or intestate succession (where property is distributed according to the laws of descent and distribution when there is no valid will).

For example, if a person dies without a will, their property will be distributed according to the laws of descent and distribution. This means that their property will pass to their closest living relatives, such as their spouse, children, or parents. This is an example of natural succession, as the property is passing from one natural person to another.
