The legal paperwork was signed on Thursday by Nigeria's Justice Minister Michael Aondoakaa and by his Cameroonian counterpart Maurice Kanto.
The handover will end a 15-year dispute over a territory believed to contain considerable oil and gas reserves.
Despite the move, President Umaru Yar'Adua insisted Nigeria would not abandon its international obligations.
"This handing-over process, as painful as it is for everyone including the president, is a commitment we have made to the international community and we have a responsibility to keep it," he said.
The enclave was awarded to Cameroon by the International Court of Justice in the Hague six years ago after a drawn-out legal battle. In the presence of then UN secretary general Kofi Annan, both sides agreed to a two-year transition during US-mediated talks.
The transfer has been threatened by last-minute legal challenges and a number of deadly attacks which led to the death of 50 people including a senior Cameroonian official.
Nigerian geographer Emmanuel Iga told RFI said there were two main problems - displaced people and compensation.
"The problem therefore is that of the resettlement of residents, that has decided to re-enter the Nigerian side and would not want to be naturalised as Cameroonians after the handover," he says.
