# Claim an unresolved contact address

`POST /contact_addresses/{id}/claim`

Attaches a currently-unresolved contact address (contact_id is NULL) to the given contact. Idempotent if already claimed by the same contact.
Default behavior (force absent or false): unchanged from before — returns 409 (Conflict) if the address is already claimed by a different, still-active (non-tombstoned) contact. Existing callers are unaffected.
force: true (new): if the address is already claimed by a different, still-active contact, the claim overwrites that ownership instead of returning 409 — the previous owner's open ownership period is closed and a new one is opened for the requesting contact. Addresses owned by a tombstoned (soft-deleted) contact are repaired in place exactly as before, regardless of force.

## Path parameters

- `id` string, uuid, required

## Request body

- object
  - `contact_id` string, uuid, required
  - `force` boolean — When true, overwrite ownership even if the address is currently claimed by a different, still-active contact (no 409). Defaults to false, which preserves the original claim behavior. Has no effect when the address is unresolved or already owned by the requesting contact.
