For SBA lenders
Short answer
Familial relationships alone do not automatically trigger affiliation; however, they become a factor if combined with other indicators of control, such as common investments, shared management, or strong economic dependence.
SBA generally avoids affiliation based solely on family ties without additional evidence of control. However, if family members (spouses, parents, children, siblings) have identical or substantially identical business or economic interests, and one business is economically dependent on the other, or they share common management or facilities, affiliation may be found. The SBA looks for the 'power to control' another entity.
A father owns 'Company A' and his son owns 'Company B.' They share administrative staff, operate from the same building, and 'Company B' generates 70% of its revenue from 'Company A.' A lender would likely find them affiliated due to the combination of familial ties, shared resources, and economic dependence, despite separate legal ownership.
