The problem raised by the peculiar fact of this case is, however, this: what is the position where no family head existed at the time. It is true that under English Law, equity does not lack a trustee: where there is none equity will constitute one. As the head of the family under Nigerian law is a trustee of a type will equity allow a vacancy in his position in such away as to defeat the right of a third party? I think not. For to do so could have disastrous consequences both to family interest and those of third parties. Now traditionally, under Yoruba customary law where no head of the family was nominated by a deceased father of the family (see Sogbesan v. Adebiyi 16 N.L.R. 26) or appointed by the members of the family, the eldest surviving male (Dawodu) is the head of the family: see Lewis v. Bankole (1908) 1 N.L.R. 82, although it was recognised that a woman could also be the head of the family (Taiwo v. Sarumi (1913) 2 N.L.R.106).
