Alhaja Kemi operates a lucrative building materials business in Ibadan, Oyo State. In January 2023, she orally agreed with her nephew, Tunde (a graduate architect working in Lagos), that if Tunde resigned from his salaried employment in Lagos and relocated to Ibadan to assist her in managing her expanding business, she would pay him an monthly allowance of ₦300,000 and transfer ownership of a residential duplex in Ibadan to him after two years of satisfactory service. Tunde resigned from his employment, relocated to Ibadan, and worked diligently for Alhaja Kemi. After 14 months, following a family quarrel during a festive celebration, Alhaja Kemi stopped paying Tunde the monthly allowance and stated that she was no longer bound to give him the duplex, claiming that "family arrangements are not real contracts enforceable in court." Separately, Prime Properties Nigeria Limited leased a commercial warehouse to Kofo Logistics Limited for 5 years at an annual rent of ₦10,000,000 payable annually in advance. In Year 3, due to severe economic downturn, Kofo Logistics Limited informed Prime Properties Nigeria Limited in writing that it could no longer pay full rent and would have to vacate. Prime Properties Nigeria Limited agreed in writing to accept a reduced rent of ₦6,000,000 per annum for Year 3 and Year 4. Kofo Logistics Limited paid ₦6,000,000 for both years. At the end of Year 4, business recovered fully. Prime Properties Nigeria Limited now demands immediate payment of the ₦8,000,000 total balance foregone during Years 3 and 4, arguing that Kofo Logistics Limited provided no consideration for the reduction.
