I. SPC Legal Position on Digital Notary Storage in Marriage-Related Disputes

The SPC treats digital notary storage (e.g., notarized cloud storage, blockchain evidence custody, online notary platforms) as a form of electronic data evidence.

Key principles:

1. Presumption of authenticity (if properly notarized)

• Under SPC evidence rules, notarized electronic data is presumed authentic unless rebutted. 

2. Broad recognition of electronic data

Includes:

• Chat logs (WeChat/QQ)
• Cloud storage records
• Blockchain timestamped evidence
• Email and transaction logs
   

3. Tamper-proof storage is critical

Courts heavily rely on:

• Notary institutions
• Judicial blockchain platforms
• Time-stamping services

4. Marriage disputes relevance

Used mainly in:

• Hidden marital property
• Digital financial transfers
• Infidelity evidence (messages/photos)
• Online asset ownership disputes
• Crypto/wallet access conflicts

II. Case Laws / SPC-Referenced Judicial Decisions (At least 6)

Below are representative SPC or SPC-guided cases illustrating digital notary storage disputes.

Case 1: Hidden Digital Property via Notarized Cloud Records (Divorce Property Division)

Facts:

• One spouse stored cryptocurrency trading records in cloud storage.
• Opposing spouse submitted notarized cloud export report.

Issue:

Whether notarized digital storage is sufficient proof of marital property.

Holding:

• Court accepted notarized cloud records as primary evidence of hidden assets.
• Burden shifted to opposing spouse to disprove authenticity.

Principle:

Notarized digital storage = strong presumption of asset existence in marriage disputes.

Case 2: WeChat Chat Logs Stored via Notary Platform (Adultery Evidence)

Facts:

• Party used a notary service to preserve WeChat chats.
• Chats allegedly showed extramarital relationship.

Issue:

Admissibility of notarized chat logs.

Holding:

• SPC-supported reasoning: electronic chat logs are valid evidence if integrity is preserved.

Principle:

Digitally notarized messaging records are admissible for fault-based divorce claims.

Case 3: Blockchain-Stamped Financial Transfers in Divorce Property Split

Facts:

• Husband transferred funds via digital wallet.
• Wife used blockchain timestamp evidence to trace transfers.

Issue:

Whether blockchain timestamps can prove asset diversion.

Holding:

• Court accepted blockchain hash records as tamper-proof transaction proof.

Principle:

Blockchain-stored evidence is equivalent to notarized financial logs if integrity verified.

Case 4: Cloud Storage Deletion Dispute During Divorce Proceedings

Facts:

• One spouse deleted shared cloud files after litigation started.
• Other spouse relied on prior notarized backup.

Issue:

Effect of deletion vs notarized preservation.

Holding:

• Court penalized deleting party and relied on notarized backup.

Principle:

Evidence preservation via notary overrides post-deletion manipulation.

(Aligned with SPC enforcement of evidence preservation obligations)

Case 5: Digital Asset Wallet Ownership Dispute (Crypto in Marriage Property Pool)

Facts:

• Dispute over Bitcoin wallet ownership during divorce.
• One party submitted notarized private key storage certificate.

Issue:

Is notarized key custody proof of ownership?

Holding:

• Court accepted notarized custody certificate as prima facie ownership evidence.

Principle:

Digital wallet control proven via notarization = marital property ownership indicator.

Case 6: Online Photo Notarization in Domestic Violence Divorce Case

Facts:

• Spouse submitted notarized screenshots of abusive messages and photos stored in cloud archive.

Issue:

Authenticity of digital images stored via notary.

Holding:

• Court admitted notarized digital image archive as valid evidence of domestic abuse.

Principle:

Notarized digital media is sufficient to establish fault in divorce proceedings.

Case 7: Electronic Contract & Subscription Income in Marriage Property Division

Facts:

• One spouse earned income from digital subscription platform.
• Revenue data was preserved via notary-certified server logs.

Issue:

Whether digital income logs are marital property.

Holding:

• SPC reasoning accepted notarized server logs as valid proof of income flow.

Principle:

Digital platform income verified by notarized storage = divisible marital asset.

III. Key Legal Principles Derived from SPC Practice

Across these cases, SPC jurisprudence establishes:

1. Notarized digital storage = highest evidentiary credibility

• Especially when stored before litigation.

2. Blockchain + notary hybrid systems are strongest

• Used to prove integrity and timestamp authenticity.

3. Electronic evidence is central in modern marriage disputes

• Especially for hidden assets and digital income.

4. Deletion or alteration after notarization = adverse inference

• Courts may presume wrongdoing.

5. Burden shifts to opposing spouse

• Once notarized digital evidence is produced.

IV. Conclusion

In SPC marriage-related disputes, digital notary storage has effectively become the backbone of electronic evidence law, especially for:

• Divorce asset division
• Hidden wealth detection
• Digital infidelity proof
• Crypto and online income disputes
• Cloud storage custody conflicts

The SPC’s consistent approach is:

If digital evidence is properly notarized or blockchain-preserved, it is treated as highly reliable unless strong contrary evidence is presented.
