Legal Definitions - consanguine sister

A consanguine sister is a type of sister who shares one parent or both parents with another person. In civil law, there are different types of sisters based on the parent they share with the other person.

• Half sister: A sister who shares either the same father or the same mother, but not both.
• Sister-german: A full sister who shares both parents.
• Stepsister: The daughter of one's stepparent.
• Uterine sister: A sister who shares the same mother, but a different father.

For example, if two sisters have the same father but different mothers, they are consanguine sisters. However, if they have the same mother but different fathers, they are uterine sisters.

Understanding the different types of sisters can be important in legal matters such as inheritance or custody battles.
