For SBA lenders
Short answer
No, a shared familial relationship alone does not automatically trigger affiliation; common ownership or control must also be present.
Affiliation is primarily based on actual or potential control. While family relationships can be a factor if they lead to common ownership or control (e.g., family members owning different businesses but pooling resources), the mere existence of a familial tie without shared control or ownership does not create affiliation.
A brother owns a landscaping company and his sister owns a separate floral shop. They share no common employees, management, or ownership. Despite their familial relationship, they are not affiliated for SBA size purposes.
