### In plain English

Inform third parties of modifications/withdrawals/objections and implement mechanisms to do so. In practice, this means you can prove you maintain inform third parties-level controls on a defined cadence.

## Why it matters

ISO 27701 is the international way to evidence the GDPR principle of accountability: certified PIMS controls translate directly into the records, contracts and rights-handling that supervisory authorities want, and into the privacy-engineering evidence SOC 2 + Privacy auditors and enterprise procurement teams ask for.

This control is rated **high**. Auditors expect a named owner, a remediation SLA, and a tooling artefact that evidences continuous operation.

## What an auditor looks for

PIMS auditors expect ISO 27001 to be implemented first and then the 27701-additional controls tested. For PII controllers they look at lawful-basis and rights-handling evidence; for PII processors they look at customer-instructions, sub-processor controls and return/transfer/disposal evidence.

Within **Obligations to PII principals**, the assessor will trace your implementation back to the catalogue reference (Annex A A.1.3.8) and look for objective evidence on the latest two assessment cycles.

## How to implement

#### Policy Management

**Docs.** Keep each policy in version-controlled Markdown alongside the code that implements it; ship a signed PDF snapshot at each annual review and link the SHA into the SoA.

### Operational checklist

-   **Maintain.** Document the trigger, the owner and the cadence.
-   **Implement.** Document the trigger, the owner and the cadence.
-   **Ensure.** Document the trigger, the owner and the cadence.
-   **Scope:** inform third parties.

## Evidence to collect

-   **Ticketing Workflow.** `ticketing_workflow` evidence
-   **Policy Document.** A signed and version-controlled policy / standard / procedure document.

Signed policies, procedures, and registers document the safeguard. Service management or request-handling tickets prove timely handling. Focus: Inform third parties.

## Common pitfalls

-   Policies that no engineer has read; the version in Confluence drifts from the version that's actually being enforced.

## How it maps to other frameworks

Computed from shared tags, control component and key-operation subjects — handy when you are reconciling controls across an audit.
