Security Agreements, Hold Harmless & Proof of Life

A security agreement is the contract between a debtor and a secured party that creates a security interest in collateral. Under UCC §9-203, attachment requires:

1. Value has been given by the secured party
2. The debtor has rights in the collateral
3. The debtor has authenticated a security agreement that describes the collateral

The description of collateral should be specific enough to identify what is covered. "All assets" descriptions are generally permissible under UCC Article 9 for commercial transactions but may be challenged in certain consumer contexts.

Best practice: Pair every security agreement with a Schedule A ledger (see UCC module) and a UCC-1 filing to perfect your interest.

A hold harmless (indemnification) agreement is a contract in which one party agrees not to hold another liable for specified risks or losses. In estate and commercial planning contexts, hold harmless clauses appear in:

• Trustee agreements (trustee held harmless for good-faith decisions)
• Private lending instruments (borrower holds lender harmless from certain regulatory exposure)
• Contractor and service agreements

In private commercial frameworks, some practitioners use hold harmless agreements as standalone instruments establishing consideration and documenting the relationship between parties. When used this way, hash-anchoring the instrument creates an immutable timestamp of when the agreement was executed and what it contained.

"Proof of life" in legal and estate contexts refers to documentation establishing that a person was alive at a specific time — critical for:

• Life insurance claim contestation
• Trust distribution triggering events
• Overseas estate administration
• Establishing legal capacity at the time of instrument execution

Methods include notarized affidavits, video attestations with witnesses, biometric records, and — increasingly — cryptographically timestamped digital records. A SHA-256 hash of a signed document, anchored to a blockchain with a public timestamp, creates evidence that the document existed in its current form at a specific point in time. It does not prove authorship, but combined with appropriate witnesses and notarization, it provides a powerful additional layer of proof.
