Buying family land in Nigeria can be complicated. A purchaser may negotiate with a family head, pay the agreed purchase price, obtain a Deed of Assignment and take possession, only to discover that other family members are challenging the transaction. Sometimes, the objection comes from principal members who claim they were never consulted. In other cases, individual family members argue that the land could not have been sold without their personal consent. These disputes raise an important legal question: Can family land be sold without the consent of every family member in Nigeria? The general rule under Nigerian customary law is that the consent of every individual family member is not necessarily required. However, a valid sale of unpartitioned family land ordinarily requires the participation of the family head and the consent of the principal members of the family. The distinction matters because a sale made without the family head may be void, while a sale made by the family head without the consent of the principal members is generally voidable at the instance of those entitled to challenge it. The legal position may also depend on the applicable customary law, the ownership structure and whether the land has been partitioned or otherwise lawfully transferred. This article explains who can sell family land in Nigeria, whose consent is required, the consequences of an unauthorised sale and the precautions buyers should take before purchasing family property. What Is Family Land in Nigeria? Family land is land owned collectively by members of a family under the applicable legal system, particularly customary law. Such land may originate from: An ancestral acquisition. Inheritance from a common ancestor. A grant made to a family. Land acquired collectively for the family. Other transactions through which property becomes family-owned. Under customary family ownership, the land is not ordinarily treated as the personal property of the family head or any individual member. The family head generally manages the property on behalf of the family, while the principal members participate in important decisions concerning its disposition. The precise rights and responsibilities depend on the applicable customary law and the circumstances. Who Owns Family Land in Nigeria? Family land belongs to the family collectively, subject to the applicable rules governing family ownership. The family head does not ordinarily own the entire property personally merely because they manage it. Similarly, an individual family member does not necessarily have the authority to sell a specific portion of unpartitioned family land without proper authorisation. The family head and principal members ordinarily exercise the relevant powers concerning management and alienation of family property. However, where the family has lawfully partitioned the land or transferred a defined interest to an individual, the legal position may be different. Before buying family land, it is therefore essential to determine whether the property remains family-owned or has become the separate property of an individual. Can Family Land Be Sold Without the Consent of Every Family Member? Yes, in appropriate circumstances. Nigerian customary law does not generally require every member of a family, including every child and distant relative, to personally sign or approve a sale of family land. The established rule ordinarily requires the participation of the family head and the consent of the principal members. The relevant inquiry is therefore not simply whether every family member signed the transaction. The important questions are: Who is the recognised family head? Who are the principal members whose consent is required? Did the family head participate in the sale? Did the principal members consent? Was the transaction conducted in accordance with the applicable customary law? Did the persons executing the documents have authority to bind the family? Was the land still family property when the transaction occurred? A buyer who fails to investigate these questions may acquire a disputed or defective title. Who Is the Family Head? The family head is the person recognised under the applicable customary law or family arrangement as having the responsibility to manage family affairs and property. The method of selecting or recognising the family head may vary. In some families, headship follows seniority. In others, the applicable custom or established family arrangement determines who exercises that responsibility. A buyer should not assume that the oldest person present at a meeting is necessarily the legally recognised family head. Similarly, the person who first introduces the property or negotiates the purchase price may not have authority to sell it. Where there is disagreement over the identity of the family head, the dispute should be resolved or properly investigated before completing the transaction. Who Are the Principal Members of a Family? Principal members are those family members whose participation or consent is required under the applicable customary law for important dealings with family property. They may include recognised representatives of major family branches or other persons whose status makes their consent necessary. Not every adult family member is automatically a principal member. Equally, a person should not be excluded merely because another family member claims to have greater authority. The correct identification of principal members depends on the family structure and applicable custom. A buyer should therefore investigate the family genealogy, relevant branches and recognised decision-making arrangements before relying on purported consent. What Happens If the Family Head Sells Land Without the Consent of Principal Members? Under the general customary-law rule, a sale made by the family head without the consent of the principal members is voidable, rather than automatically void. This means the transaction may be challenged and set aside by persons legally entitled to complain. The distinction between a void and voidable sale is important. A voidable transaction is not treated in precisely the same way as a transaction that is void from the beginning. Whether the sale will ultimately be set aside may depend on the circumstances, including the conduct of those entitled to challenge it and the applicable legal principles. For a purchaser, the practical risk is significant. A buyer may pay the purchase price, receive documents and commence development, only to
