Land Tenure Question in the Cameroons

Does anyone have information on exactly how
the laws in the Cameroons (customary, common and, I daresay, Napoleonic)
come together to dictate how transactions
and agreements about land are carried out?

Before the Europeans came, our ancestors carried out transactions
and agreements on the land. So this means (or I understand it to mean)
they operated under customary (or traditional) law.

When the British governed Anglophone Cameroons, I know (because I lived it)
they had a system in which common law was slowly integrated with traditional, customary law,
to manage the day-to-day business of the people. At one point, the Alkali courts even
handled the issues of the Muslim communities: Hausa, Bororo, Fulani, etc. (I know this because I lived it.)

So my question is: our ancestors, on their own, used customary and traditional law
to manage their land and the property handed down to them by their ancestors.
Has the introduction of common law (from the British) and the
Napoleonic Code (from the Francophone Cameroons) made it easier for our people to understand
land tenure in the Cameroons, or not? If so, how?

Thanks for your feedback.
