Can I Send a QES-Based Signature Request to Multiple Recipients?
Published:
Yes, you can send a Qualified Electronic Signature (QES) request to multiple recipients. However, certain rules must be followed to ensure QES is enabled for all signers.
Core Rules for QES with Multiple Recipients
1. Sequential Signing Required
- Each signer must have a unique signing order.
- QES works only when the signing flow is strictly sequential, without duplicate order numbers.
2. Parallel Signing Not Allowed
- If two or more recipients share the same signing order, QES is disabled for all signers except the final signer in that sequence.
3. No Duplicate Order Numbers
- To enable QES for all recipients, every signer must have a distinct signing order.
QES Eligibility Based on Signing Order Scenarios
| Scenario | Signing Order | Multiple QES Enabled for All | Result |
|---|---|---|---|
| Valid Sequential | 1 → 2 → 3 | Yes | All signers are eligible for QES |
| Valid Non linear Sequential | 3 → 1 → 2 | Yes | All signers are eligible for QES (order can be arbitrary but must be unique) |
| Parallel Signing | 1 → (2, 2) → 3 | No | Only the final signer is eligible for QES |
| All Parallel | (1, 1, 1) | No | Only the final signer is eligible for QES |
| Duplicate Orders | 1 → 2 → 2 → 3 | No | Only the final signer is eligible for QES |
Configuration Steps
When preparing a document for signing that includes multiple recipients, follow these steps:
- On the Document Prepare page, add all the recipients you want to include and enable the
signing order.
- Enable
QESfor all recipients in theSettingssection.
- Assign a unique signing order to each recipient.
- Once all recipients are configured, send the document. This will enable QES for all signers.
