A more thorough explanation:

Definition: In equal right.

Explanation: This term is used in law to indicate that two or more parties have the same legal rights. For example, if two people inherit property from a deceased relative, they have in aequali jure rights to the property. This means that they have equal rights to use, sell, or dispose of the property as they see fit.

Example: John and Jane both inherit their father's house. They have in aequali jure rights to the property, which means that they both have equal rights to use, sell, or dispose of the property as they see fit.
