A more thorough explanation:

Definition: Sucesión legítima is a legal term in Spanish law that refers to the process of regular inheritance. The rules of sucesión legítima cannot be altered by a will.

For example, if a person dies without leaving a will, their property will be distributed according to the rules of sucesión legítima. The law will determine who the heirs are and how the property will be divided among them.

This term is important because it ensures that property is distributed fairly and according to established legal guidelines. It also helps to prevent disputes and conflicts among family members over inheritance.
