# Scope: what each member of the family owns

How a member states what it holds, so that no two members hold the same thing. The shape is the
[scope table](../../shapes/scope-table.md).

| Principle | Claim |
|---|---|
| [One owner per claim](one-owner-per-claim.md) | a thing is in the scope of one member; every other member links it |
| [A scope table says why](scope-table-with-why.md) | a member's scope is a table of in, later and out rows, each with its reason |
