In Thailand, a debt without security represents a commercial risk.

Security Agreements provide structured creditor protection under the Civil and Commercial Code and related legislation.

For corporate investors and financing transactions, security mechanisms are commonly used in:

  • Shareholder loan protection

  • Real estate project financing

  • Asset-backed lending

  • Joint venture capital protection

  • Cross-border lending structures

Security must be aligned with the underlying loan structure.

1. Suretyship (Personal Guarantee)

Suretyship is a contract whereby a third party undertakes to satisfy the obligation if the debtor defaults.

Key legal features:

  • Must be evidenced in writing

  • Provides personal liability

  • Natural persons receive statutory protection

  • Joint liability is subject to legal safeguards

Often used in:

  • Director guarantees

  • Parent company guarantees

  • SME credit facilities

However, suretyship attaches to a person — not to property.

2. Mortgage (Security Over Registered Assets)

A mortgage allows property to secure debt without transfer of possession.

Requirements:

  • Written contract

  • Registration with competent authority

  • Applies primarily to immovable property

  • Certain registered movables may qualify

Common in:

  • Real estate development financing

  • Industrial project lending

  • Leasehold asset structures

Mortgage enforceability must consider registration priority and procedural enforcement.

3. Pledge (Security by Delivery)

A pledge requires delivery of movable property to the creditor.

Without delivery, no valid pledge exists.

For rights represented by written instruments, delivery and written notification are required.

Often used in:

  • Share pledge arrangements

  • Equipment security

  • Inventory collateral

4. Corporate Security Structuring

In commercial practice, security agreements are often layered:

Loan Agreement + Mortgage + Share Pledge + Suretyship

Each instrument addresses different risk dimensions.

Structuring should consider:

  • Priority ranking

  • Registration costs

  • Bankruptcy implications

  • Cross-border enforcement

  • Director liability exposure

5. Cross-Border & Tax Considerations

Security arrangements may interact with:

  • Withholding tax on secured obligations

  • Transfer pricing rules in intercompany financing

  • Permanent establishment exposure

Relevant frameworks:

Strategic Advisory Note

Security Agreement Thailand structures must be designed alongside:

  • Corporate governance planning

  • Financing strategy

  • Tax compliance

  • Enforcement feasibility

Improperly structured security may be invalid, unregistered, or unenforceable — undermining creditor protection.

Structured documentation ensures commercial defensibility.
