EVIDENCE GUIDE
How to Build a PDPL Evidence Library
Create a connected evidence structure that brings policies, decisions, assessments, agreements, registers and operating records together for assurance and regulatory readiness.
Use the working sequence below to connect the decision to operating implications, retained evidence and the point where specialist DPO support may be required.
Prepared by DPO Arabia
Practical KSA PDPL guidance, not organisation-specific legal advice.
KSA PDPL GUIDE
Build the evidence library around what each PDPL control must prove.
The Guide frames the decisions around authoritative evidence, ownership, access, version control and review so the evidence base can be trusted and retrieved. The organisation-specific conclusion should be validated before implementation.
USE THIS WHEN
Use when evidence is scattered, duplicated, stale or difficult to retrieve.
Apply it during Data Protection Officer (DPO) Office setup, audit remediation, review-readiness work or when control evidence sits across multiple teams and repositories.
HAVE READY
Bring the control framework, existing repositories, evidence owners and current records.
Useful inputs include policies, registers, approvals, contracts, assessments, governance records, system evidence and existing folder structures available.
OUTCOME
Finish with a controlled evidence architecture that the DPO Office can maintain and retrieve.
A complete evidence set retains the evidence map, authoritative sources, owners, access rules, version controls, quality checks and review cadence.
HOW TO USE THIS GUIDE
Use the Guide to frame the decisions before implementation.
This Guide highlights the decisions, evidence and operating interfaces that should be resolved before the requirement is treated as complete.
Use it to understand the issue, challenge the relevant facts and identify where organisation-specific legal, operational or technical input is needed.
GUIDE OUTCOME
A controlled PDPL evidence library with authoritative sources, ownership and review built in.
The objective is a defensible decision and an operating control, not simply a completed template or document.
QUESTIONS TO RESOLVE
What should the DPO Office establish?
- DEFINE EVIDENCE DOMAINS
- IDENTIFY SOURCE OF TRUTH
- SET OWNERSHIP
- CONTROL VERSIONING
- TEST RETRIEVABILITY
- REVIEW CURRENCY
EVIDENCE LIBRARY CHECKPOINT
01
What PDPL obligations, controls and processing activities need retained assurance evidence?
02
Which record is the authoritative source for each piece of evidence?
03
How will evidence link to the Record of Processing Activities (RoPA), registers, assessments, agreements and responsible owners without creating uncontrolled duplicates?
04
How will versions, approvals, access and sensitive evidence be controlled?
05
Who maintains the evidence library, how is its quality reviewed and what triggers remediation when evidence is missing or stale?
WORKING STEPS
Use the sequence to identify the decisions that need to be resolved.
Define the evidence architecture
Design the evidence structure around how PDPL compliance must be demonstrated.
What to validate in practice
- Identify the PDPL control areas and processing activities that need retained assurance evidence.
- Decide what belongs at organisation level versus processing-activity, system, Processor or case level.
- Define the evidence taxonomy, naming convention, metadata fields, accountable library owner and evidence-retention rules.
- Decide when evidence is stored centrally and when the library should retain a governed link to an authoritative source system.
- Confirm the architecture supports governance, operational, third-party, transfer and assurance evidence without creating parallel uncontrolled repositories.

ARCHITECTURE PRINCIPLE
Design the library around how compliance will be demonstrated, not around how departments happen to store files.
Identify authoritative evidence
For each evidence type, identify the approved source of truth and what actually demonstrates that the control is operating.
What to validate in practice
- Identify the authoritative source for each evidence type and distinguish approved records from drafts, working copies and convenience copies.
- Confirm the evidence is current, complete, approved or executed where required, and consistent with operational reality.
- Check that the record proves the relevant control rather than merely restating the requirement or describing an intended process.
- Identify conflicting copies, missing approvals or evidence that cannot be retrieved without reconstructing the activity later.
- Record the accountable evidence owner and the system or repository in which the authoritative record is maintained.

SOURCE-OF-TRUTH RULE
Evidence should prove the control, not merely describe it. Preserve the approved source or a governed link to it.
Organise and link evidence
Connect authoritative evidence so the DPO Office can trace an obligation or processing activity across the records that support it.
What to validate in practice
- Link evidence to the relevant RoPA activity, control or obligation, business owner and system or service.
- Connect related assessments, agreements, Processor or disclosure records, register entries, approvals and remediation items.
- Define common metadata such as evidence type, source location, owner, approval/effective date, review date and status.
- Avoid duplicating authoritative records where the evidence library can reliably index or reference the controlled source.

LINK, DO NOT DUPLICATE
Use the library as an evidence index and assurance layer. The authoritative contract, assessment or system record can remain in its controlled source repository.
Control versions and access
Protect the integrity and confidentiality of the evidence repository itself.
What to validate in practice
- Identify the current approved version, effective date, approval authority and superseded status for controlled evidence.
- Define who may view, edit, approve, delete or externally share evidence and apply least-privilege access.
- Restrict Sensitive Data and confidential evidence appropriately, including DSR, breach, workforce and security-related records.
- Preserve version and change history where needed to explain material decisions, approvals or prior control states.
- Confirm repository integrity, backup/recovery and deletion controls are appropriate for the evidence being maintained.

ACCESS CONTROL
The evidence library can contain significant Personal Data and confidential material. Evidence governance must include governance of the repository itself.
Review and maintain evidence quality
Operate the evidence library as a living DPO Office control.
What to validate in practice
- Operate the evidence library as a living DPO Office control.
- Identify missing, stale, obsolete, duplicate or conflicting evidence and records still awaiting approval or execution.
- Check for broken source links, expired agreements, changed processors, new transfer locations and material RoPA changes.
- Track evidence gaps through remediation with accountable owners, target dates and validation of closure.
- Maintain evidence-health review history and provide management with a clear view of material assurance gaps and repository status.

OPERATING PRINCIPLE
A well-designed evidence library degrades if it is not actively maintained. Treat evidence quality as a recurring assurance activity.
EVIDENCE TO RETAIN
Know what evidence should remain after the work is complete.
Retain the evidence catalogue, source-of-truth mapping, ownership model, access rules, version controls, review cadence, quality findings and remediation records that govern the evidence library itself.
RETAINED EVIDENCE SET
Keep evidence indexed by control, owner, source and review date.
Retain version history so the DPO Office can prove what was current at any point.
Approved evidence-library architecture
Evidence taxonomy
Naming convention
Metadata standard
Evidence inventory
Authoritative-source mapping
RoPA linkage model
Register linkage model
Ownership matrix
Access-control matrix
Approval and version-control rules
Evidence-retention rules
Sensitive-evidence handling rules
Source-system / repository mapping
Broken or stale evidence log
Periodic evidence-health review
Remediation actions
Change history
Management assurance view
Repository governance approval
BEFORE YOU CLOSE THE WORKFLOW
Validate the operating position, not only the document.
Before treating the evidence library as operational, confirm that authorised reviewers can find the correct record, identify the approved source, understand who owns it and recognise when evidence is stale, missing or superseded.
Use the checks below to test whether the evidence library can support assurance, management review and regulatory requests without relying on individual knowledge or duplicate files.
FROM GUIDANCE TO OPERATION
Connect the decision to the wider DPO Office.
An evidence library becomes operational when authoritative sources, ownership, access, review and remediation stay connected to the controls that generate the evidence. Use this handoff to make evidence quality part of the DPO Office cadence.
01
Apply the DPO guide
Use the guide to catalogue evidence, define authoritative sources, assign owners, control access and establish review and quality checks.
03
Connect the controls
Connect the evidence library to the RoPA, operational registers, assessments, agreements, Processor and transfer records, remediation tracker and management reporting so current proof of compliance can be retrieved without rebuilding the evidence trail.
