O'Brien v. O'Brien

O'Brien v. O'Brien (1965) was a Supreme Court case about whether a father could prevent his adult son from competing with his business after the son inherited a similar business. The Court ruled that a father can't use a legal agreement made before inheritance to restrict his son’s lawful business activities afterward. The case established that such restrictions must be reasonable and not overly broad, emphasizing that family members have the right to pursue their trade unless specifically limited by fair agreements.
