According to the Land Use Act all land belongs to the government so the Governor is the owner of all land even the one in your village, and he alone will determine what to do with the land not even your Igwe, Oba or Emir.
So it is only when the Governor has taken the land he want to use that he give the remaining to the traditional family to do whatever they want to do with it.
A good example is what happened in Oniru, before now there was nothing like Victoria Island Ikoyi and Lekki the whole area put together was formally known as one big community called Oniru and it has an approximate total area square meters estimate of 100,000 square meters and the government was interested in that area and decided to take 70,000 square meters for its self for its own personal use as an Urban Area or public purpose, it will record this acquisition in the official government gazette and also record that the remaining 30,000 square meters has been left alone for the traditional family to have and do with it whatever it pleases it to do.
So A Gazette is an Official record book where all special government details are spelt out, detailed and recorded. A Gazette will show the communities or villages that have been granted excision and the number of acres or hectares of land that the government has given to them.
It is within those excised acres or hectares that the traditional family is entitled to sell its lands to the public and not anything outside those hectares of land given or excised to them.
A Gazette is a very powerful instrument the community owns and can replace a Certificate of Occupancy to grant title to the Villagers.
A community owning a gazette as a land document can only sell lands to an individual within those lands that have been excised to them and the community or family head of that land has the right to sign your documents for you if you purchase lands within those excised acres or hectares of land.
If the government based on some reasons best known to them decides to revoke or acquire your land, you will be entitled to compensation as long as it’s within the Excised lands given to that community.
The best way to know whether a land is under acquisition or has an excision that has been covered by a Gazette is to get a surveyor to chart the site and take it to the surveyor general’s office to do a land information search so as to confirm whether it falls within the gazette and spell out which particular location it can be found.
