Providing a definitive list is difficult because:
* Lack of Public Information: Many fraternities operate with a degree of secrecy. Their membership and activities aren't always publicized.
* Fluidity of Organizations: The number and prominence of fraternities can change over time. Some may dissolve while others emerge.
That being said, some of the universities most commonly associated with having active legal fraternities include (but are not limited to):
* University of Santo Tomas (UST): Known for having a significant number of legal fraternities.
* Ateneo de Manila University: Has a history of legal fraternities, though their activity might be less visible than in some other schools.
* University of the Philippines (UP) College of Law: While UP generally discourages fraternity involvement, there's still a history and some presence of legal fraternities.
It's crucial to remember that this is not an exhaustive list and the level of activity and influence of these fraternities can vary considerably. Further research specific to each university's College of Law would be needed for a more comprehensive understanding.
