Boundary ambiguity in families refers to which concept?

• A. Boundary ambiguity refers to the clarity of family boundaries.
• B. Boundary ambiguity is uncertainty about who is in or out of the family system or caregiver roles.
• C. Boundary ambiguity is a legal term for custody disputes.
• D. Boundary ambiguity has no impact on family functioning.

Answer: (B)

Boundary ambiguity describes uncertainty about who is in or out of the family system and who holds caregiving or other family roles. In family systems theory, clear boundaries help define who belongs and who is responsible for what. But during transitions—such as divorce, remarriage, deployment, illness, or death—these boundaries can blur, leaving family members unsure about who should be cared for, who counts as a member, or who has authority. This uncertainty can create stress, miscommunication, and role confusion, which in turn can affect overall family functioning. So the concept centers on the lack of clarity about membership and caregiving roles, not on the idea of clear boundaries, legal custody, or the notion that it doesn’t impact family life.
