Legal Definitions - consanguineus frater

Consanguineus Frater

This historical legal term refers to a half-brother who shares the same father but has a different mother. It emphasizes the paternal bloodline connection between two siblings who do not share the same maternal parent.

Here are some examples to illustrate this concept:

• Imagine a man named Arthur who had a daughter, Eleanor, with his first wife. After his first wife passed away, Arthur remarried and had a son, Thomas, with his second wife. In this scenario, Eleanor and Thomas would be considered consanguinei fratres because they share Arthur as their father, even though they have different mothers.

• Consider a situation where Maria has a son, Daniel, with her partner, David. Later, Maria and David separate. David then enters a new relationship and has a daughter, Sophia, with his new partner. Daniel and Sophia are consanguinei fratres because David is the biological father to both children, but they were born to different mothers.
