How To Secure MT799 Transactional Proof Of Funds When You Do Not Have The Funds Yourself
Another company can sometimes support a proof-of-funds process on your behalf, but the structure must be disclosed, documented and acceptable to the banks involved. The proof cannot pretend that your company owns or controls funds that actually belong to someone else.
Plain point. Third-party proof of funds can work when the third party is a disclosed sponsor, parent company, JV partner, investor, lender, escrow depositor or account holder with a legitimate role in the transaction.
What MT799 Proof Of Funds Actually Means
MT799 is commonly used as a free-format SWIFT bank message. In trade finance, it can be used for pre-advice, confirmation of intent, transactional comfort or proof-of-funds communication between banks.
An MT799 does not transfer money. It does not automatically create a payment guarantee. It does not replace an SBLC, bank guarantee, documentary letter of credit or funded escrow. The value of the message depends on the sending bank, the wording, the account relationship, the funds being referenced and the receiving bank’s willingness to rely on it.
The issue is not whether another company has money. The issue is whether the third-party support is real, disclosed, controlled and legally tied to the transaction.
Can Another Company Post Proof Of Funds On Your Behalf?
Yes, in some transactions. A third-party company can support proof of funds when it has a clear commercial role and agrees to make its financial capacity available for the defined transaction.
The structure must be honest. If the money belongs to the sponsor, the bank message should not imply that the applicant owns the money. If the sponsor is only willing to support the transaction under conditions, those conditions need to be documented.
Hard rule. Never use a third party’s funds to create a false impression that your company has cash it does not own, control or have committed access to. Banks, sellers and counterparties treat that as a serious misrepresentation risk.
Legitimate Third-Party POF Structures
| Structure | How It Works | What Must Be Clear |
|---|---|---|
| Parent Company Support | A parent company or group affiliate provides proof that funds are available to support the subsidiary’s transaction. | Corporate relationship, board approval, funding commitment and permitted use of funds. |
| JV Partner Or Consortium Sponsor | A joint venture partner supports the proof-of-funds requirement for a transaction being pursued by the group. | JV agreement, role of each party, funding obligation and transaction authority. |
| Investor-Backed POF | An investor shows capacity to fund or back the transaction subject to agreed terms. | Subscription agreement, funding commitment, conditions precedent and use-of-funds limits. |
| Lender Or Credit Facility Support | A lender or bank facility supports the buyer’s ability to close, subject to final conditions. | Facility letter, drawdown conditions, expiry, committed amount and lender consent. |
| Escrow Or Custody Structure | Funds are held by a bank, escrow agent or custodian for the transaction. | Escrow agreement, release conditions, beneficial owner, account bank and control terms. |
| Pledged Deposit Support | A sponsor places or pledges funds to support the transaction or banking instrument. | Pledge documentation, bank control, release conditions and sponsor authorization. |
What The MT799 Should Say In A Third-Party Structure
The wording should match the real structure. If the sponsor owns the funds, the message should reflect sponsor support. If funds are held in escrow, the message should refer to the escrow or account arrangement. If the funding is conditional, the conditions should be handled clearly in the transaction documents.
A clean MT799 proof-of-funds process should identify the transaction, the relevant amount, the bank relationship, the account or facility context, the role of the funds and the party whose capacity is being referenced.
Name The Real Funding Party
The message and support documents should identify whether the funds belong to the applicant, sponsor, parent, investor, lender or escrow account.
Prove Consent
The third party should authorize the use of its financial capacity for the transaction through proper corporate approvals.
Define Access To Funds
The receiving party will want to know whether funds are available, committed, reserved, pledged, escrowed or merely referenced.
Documents Usually Needed
A bank will usually want more than a short email from the sponsor. Third-party proof of funds touches ownership, control, AML risk, authority and transaction purpose.
| Document | Purpose | Practical Notes |
|---|---|---|
| Transaction Contract | Shows why proof of funds is being requested. | Should match the amount, parties and closing sequence. |
| Sponsor Agreement | Shows the third party has agreed to support the transaction. | Can be a parent support letter, JV agreement, funding agreement or investor commitment. |
| Board Resolution | Confirms corporate authority. | Useful where the sponsor is a company and funds are material. |
| Source Of Funds Evidence | Supports AML review. | May include bank statements, sale proceeds, investment records, audited accounts or funding source records. |
| Bank Instruction | Authorizes the bank to send the MT799 or related bank communication. | Must come from the account holder or authorized signatories. |
| Escrow Or Custody Agreement | Shows funds are controlled for the transaction. | Most useful where the recipient wants more than a comfort statement. |
Best Structures When You Do Not Have The Funds Yourself
Parent Company POF
A parent company can support a subsidiary when the group has real funds and the parent approves the transaction. This is often easier to explain than unrelated third-party support.
JV Sponsor POF
A JV partner can support proof of funds when the parties have a signed agreement and the transaction proceeds are clearly allocated.
Escrowed Funds
Escrow gives the receiving party more comfort because funds are held under defined release conditions rather than only described in a message.
Committed Facility
A lender facility or approved credit line can support proof of funds when the amount, draw conditions and availability period are clear.
Practical Example
A trading company wants to buy USD 20 million of product, but it does not have USD 20 million sitting in its own bank account. A larger parent company agrees to support the transaction.
The parent signs a support letter and board resolution. The purchase contract identifies the buyer, seller and parent support arrangement. The parent instructs its bank to send an authenticated bank-to-bank message confirming that the parent has financial capacity for the defined transaction, subject to the agreed terms.
That structure is clean because the source of financial capacity is disclosed. The buyer is not pretending to hold funds it does not have. The seller can evaluate the actual support party, the bank, the wording and the closing conditions.
What A Counterparty Will Usually Ask
| Counterparty Question | Why It Matters | Better Answer |
|---|---|---|
| Who owns the funds? | Ownership affects reliance and legal risk. | Identify the applicant, sponsor, parent, investor, lender or escrow account. |
| Are funds committed or only available? | Available cash is different from a legally committed funding obligation. | Provide the support agreement, escrow terms or facility letter. |
| Can the bank verify the message? | Counterparties want bank-to-bank authentication. | Use the receiving bank’s official SWIFT route and avoid email-only proof. |
| What are the release conditions? | The seller needs to know what must happen before funds move. | Tie release to contract milestones, title transfer, inspection, shipment or closing documents. |
| Is source of funds clean? | Banks must manage AML, sanctions and financial crime risk. | Prepare source-of-funds and source-of-wealth evidence before the bank asks. |
Red Flags To Avoid
Fake Ownership Language
The message suggests your company owns funds that actually belong to another entity.
No Source Of Funds
The sponsor refuses to document where the funds came from or why they are available.
Email-Only Proof
The counterparty is asked to rely on screenshots, PDFs or forwarded emails instead of authenticated bank communication.
Unrelated Sponsor
The sponsor has no clear commercial, ownership, lending, investment or escrow role in the transaction.
Upfront Fee Pressure
A broker asks for a large fee before bank verification, source-of-funds review or transaction documentation.
Promise Of Guaranteed Acceptance
No one can guarantee that a seller, bank or counterparty will accept a third-party MT799 proof-of-funds message.
Bottom line. A third-party POF can support a transaction. A false third-party POF can destroy the transaction and expose everyone involved to banking, legal and fraud risk.

Frequently Asked Questions
Can another company post proof of funds on my behalf?
Yes, when the company is a disclosed sponsor, parent, investor, JV partner, lender or escrow participant with a legitimate role in the transaction. The structure must be documented and accepted by the relevant banks and counterparty.
Can an MT799 prove funds that are not in my company’s account?
It can communicate third-party financial support if the wording accurately identifies the source of capacity. It should not imply that your company owns or controls funds that belong to another party.
Is MT799 proof of funds a payment guarantee?

What is the safest third-party proof-of-funds structure?
The safest structure is usually one where the third party is clearly identified, the funds are controlled through a bank, escrow or facility, and the transaction documents explain the third party’s role.
What will banks check before sending an MT799?
Banks usually check customer authority, account relationship, source of funds, purpose of the message, transaction documents, sanctions exposure, AML risk and the proposed wording.
