Collateral Acknowledgment

What this document is

A collateral acknowledgment records that a borrower has handed an item, or a document such as a vehicle registration book, to a lender as security for a loan. It describes the item and its condition, states which loan it secures and its rough value, and sets out what happens next: the item comes back when the loan is repaid, and the document says what the lender may do if it is not.

Informal secured lending is common everywhere: a gold necklace left with a relative against a THB 30,000 loan, a motorbike's registration book held until a debt is cleared, a laptop kept as security between friends. Without a written record, these arrangements go wrong in predictable ways: arguments about the item's condition, its value, or whether it was security at all rather than a gift or a sale.

When to use it

• A borrower leaves gold jewellery with the lender as security for a THB 30,000 cash loan.
• A lender holds a motorbike or car registration book until a personal loan is repaid.
• A friend keeps a camera or laptop as security for a short-term loan between friends.
• An existing loan is being extended and the lender asks for an item as added security.
• Both sides want to record the item's condition and value at handover so its return cannot be disputed.

When not to use it

• The security is land, a house, or a formal vehicle title transfer. Registered security over property has formal legal procedures; use a professional.
• The arrangement is really a pawn transaction with a licensed pawnshop, which follows its own regulated process.
• The lender intends to use or sell the item during the loan. That is not holding security; it needs a different and clearer arrangement.
• The item belongs to someone other than the borrower. Security over another person's property creates serious problems; do not document around them.

Information you will need

• Full names and ID details of the borrower and the lender
• Reference to the loan the collateral secures: date, amount, and repayment deadline
• A precise description of the item: brand, model, serial number, weight, or registration details
• The item's condition at handover, ideally supported by dated photos
• The value both sides place on the item
• Where and how the item will be kept during the loan
• The conditions for returning it, normally full repayment of the loan
• What the lender may do if the loan is not repaid by the deadline
• Date of handover and signatures of both parties

Clauses included

How to sign it

Sign at the moment the item changes hands, and attach evidence of its condition: photos with a visible date, serial numbers, and for gold, the weight noted in front of both parties. The acknowledgment should read like a receipt for the item, not just a promise about it.

Both parties keep a signed copy along with the photos. If the item is valuable, a witness to the handover is worthwhile, since condition disputes usually come down to one person's word against another's.

When the loan is repaid, do the paperwork in reverse: the borrower signs a short line confirming the item was returned in its recorded condition, and the lender keeps that with the closed loan file. An open-ended handover record with no return record invites a later claim that the item was never given back.

Common mistakes

• Describing the item loosely, such as one gold necklace, with no weight, photos, or distinguishing details.
• Skipping the agreed value, then arguing after default about whether the item covered the debt.
• No clause on what happens if the loan is not repaid, leaving the lender holding an item they cannot clearly do anything with.
• The lender using the item during the loan, changing its condition and undermining the whole record.
• Failing to document the return, so the handover record outlives the loan and resurfaces in a dispute.
• Holding security worth several times the loan without recording how surplus value is handled.
