What are KYB documents for a forex broker?

KYB documents are the records a broker or prop firm submits so a bank, payment provider or technology vendor can verify the business itself, not just its individual customers. They typically cover company registration, ownership and beneficial ownership, director identification, business activity, and in some cases regulatory status and source of funds.

What is the difference between KYB and KYC?

KYB (Know Your Business) verifies a company: its registration, ownership, directors and activity. KYC (Know Your Customer) verifies an individual person opening an account or trading with the business. A broker typically goes through KYB with its own providers while running KYC on its own clients.

What documents prove UBO ownership?

UBO ownership is usually evidenced through a shareholder register, a signed UBO declaration, an ownership structure chart showing percentage holdings, and identification and proof of address for each qualifying beneficial owner. Corporate shareholders may need to provide their own registration documents in turn.

What is source of funds?

Source of funds explains where the specific money involved in a transaction or account came from. Depending on the provider and risk profile, evidence can include bank statements, invoices, business revenue records, loan agreements or investment documentation.

What is source of wealth?

Source of wealth looks at the bigger picture: how an individual or business built up its overall net worth over time, rather than the origin of one transaction. Evidence can include audited financials, tax records, business sale documentation or long-term investment history.

Do prop firms need KYB?

Most prop firms go through some form of KYB when opening bank accounts, integrating payment providers, or onboarding with a trading platform or CRM vendor, because those providers need to verify the business behind the account. The depth of the review depends on the firm's structure, payout model and the provider involved.

Do payment providers require more KYB documents than technology providers?

Payment providers often request more detail on transaction flows, refund and chargeback handling, expected volumes and customer geography, because they carry direct settlement and financial-crime exposure. A technology provider supplying a platform or CRM may focus more narrowly on company identity and authorized representatives.

How recent should KYB documents be?

Most providers expect company registry extracts, bank statements and proof-of-address documents to be recent, often within the last three to six months, though the exact window is set by each provider's own policy rather than a single universal rule.

Do KYB documents need to be notarized?

Not always. Some providers accept certified copies or plain scans, while others require notarization for specific documents such as identification or corporate resolutions. This depends on the provider’s policy, the jurisdiction involved and the risk level assigned to the applicant.

Do foreign documents need apostille or legalization?

Sometimes. Where a document is issued in one country and used in another, a provider may request an apostille or consular legalization to confirm it is genuine. Whether this applies depends on the countries involved and the specific provider's requirements, so it should be confirmed directly with them.

Why can a provider request additional documents after submission?

KYB is often an iterative review rather than a single upload. A provider may ask follow-up questions once it sees the ownership structure, business model or transaction flow in detail, particularly where the business operates across multiple jurisdictions or has a more complex corporate structure.

KYB Document Checklist for Platform and Payment Onboarding

Preparing the right documents before KYB review can prevent avoidable onboarding delays.

Requirements vary by jurisdiction, business model and provider.

What documents are usually required for broker KYB?

A broker or prop firm KYB pack commonly includes company registration records, constitutional documents, ownership and UBO evidence, director identification, proof of business address, business activity information, regulatory documents where applicable, and source-of-funds or source-of-wealth evidence. Banks, payment providers and technology vendors may request additional documents based on the business model, jurisdiction and risk profile.

Definitions

What Is KYB for a Forex Broker or Prop Firm?

KYB stands for Know Your Business. It is the process a bank, payment provider, trading platform or CRM vendor uses to confirm that a company is legitimate, properly registered, and controlled by people it can identify. For a broker or prop firm, KYB usually happens before an account, integration or payment rail is switched on, and it can resurface later if the business changes ownership, expands into new markets or increases transaction volume.

Most KYB delays are not caused by one missing document. They happen because the information across several documents does not line up — a director listed on the registry extract who is missing from the shareholder register, or a business address on the bank statement that does not match the one on the company's incorporation certificate. Reviewers notice this quickly, and it usually triggers a request for clarification rather than an outright rejection.

KYB

Verifies the business entity itself: who registered it, who owns it, who runs it, and what it actually does.

KYC

Verifies an individual person, typically the broker's own client, before that person can open an account or trade.

AML

The broader set of controls — policies, monitoring, screening — used to detect and manage money-laundering and financial-crime risk across the business.

Document Preparation Table

A closer look at ten documents that appear across almost every KYB request, what each one is meant to prove, and where applicants most often trip up.

License / regulatory registration	Confirms authorization to operate, where applicable	Banks, technology vendors, liquidity providers	Submitting an application instead of a granted license	Clarify current regulatory status explicitly
Website / business evidence	Confirms the business operates as described	PSPs, banks, technology vendors	Website content inconsistent with the application	Align website, T&Cs and application before submission

Document quality

How to Prepare KYB Documents Correctly

Individually valid documents can still cause delays if they do not agree with each other. These practices reduce the number of clarification requests a provider needs to send.

Use current documents rather than whatever is easiest to find in storage.
Make sure the company name is spelled identically across every document.
Check that registration numbers match on every form and certificate.
Confirm dates are current and internally consistent — an expired certificate undermines an otherwise complete pack.
Keep ownership information consistent between the shareholder register, UBO declaration and structure chart.
Use clear, legible scans rather than photos taken at an angle.
Avoid cropped pages — submit full documents, including blank or signature pages where relevant.
Provide complete documents rather than excerpts, unless a provider specifically asks for an excerpt.
Explain unusual ownership structures proactively instead of waiting for a question.
Translate documents into the language required by the provider when requested.
Confirm whether notarization or certification is required before assuming a plain copy is sufficient.
Check whether apostille or legalization is requested for documents issued abroad.
Keep a consistent file-naming system so nothing gets misfiled during review.
Maintain a secure, access-controlled document repository rather than scattering files across email threads.

Common delays

Why Broker KYB Applications Get Delayed

Ownership mismatch

The shareholder register, UBO declaration and structure chart don't agree with each other.

Fix: Reconcile all three documents before submission and update them together whenever ownership changes.

Expired documents

Registry extracts, proof of address or bank statements fall outside the provider's accepted date range.

Fix: Refresh time-sensitive documents shortly before submitting, not weeks in advance.

Incomplete registry records

A registry extract is missing pages or does not reflect a recent change, such as a new director.

Fix: Pull a fresh, complete extract directly from the registrar.

Unclear source of funds

The evidence provided doesn't clearly connect to the amount or transaction being reviewed.

Fix: Provide documentation that traces the specific funds, not just general company income.

Business model not clearly explained

The application describes the business in vague or generic terms.

Fix: Describe products, clients, revenue sources and transaction flow in concrete detail.

Website does not match application

The live website describes different services, markets or terms than the application states.

Fix: Align the website, Terms and Conditions and application before submitting.

Unsupported target countries

The stated target markets fall outside what the provider is willing or able to support.

Fix: Confirm supported markets with the provider before listing target countries.

Missing corporate shareholder information

A shareholder is itself a company, and its own ownership hasn't been disclosed.

Fix: Trace ownership through each corporate layer down to natural persons.

Inconsistent company addresses

Registered office, operating address and bank records list different addresses without explanation.

Fix: Use consistent addresses or be ready to explain legitimate differences.

Poor-quality scans

Blurry, cropped or low-resolution scans slow down manual review.

Fix: Scan documents at a readable resolution and check them before sending.

Missing translations

Documents issued in a language the provider cannot read are submitted without translation.

Fix: Confirm translation requirements early and use a certified translator if required.

Provider asks for additional information

The initial review raises questions that require a second round of documents.

Fix: Treat this as a normal part of the process and respond promptly and completely.

Provider differences

Why Every KYB Checklist Is Slightly Different

There is no single universal KYB document list. What a provider asks for reflects the risk it is taking on and the role it plays in the transaction chain.

Banks

Banks tend to focus heavily on ownership structure, source of funds and expected transaction flows, since they hold the underlying account and carry direct exposure to the client relationship.

Payment service providers

PSPs typically concentrate on the payment model, the website and Terms and Conditions, refund and chargeback controls, expected transaction volume and customer geography.

Trading platform providers

Platform vendors generally look at the business model, company identity, authorized representatives and the technical scope of the integration, alongside general compliance status.

Liquidity providers

Liquidity providers focus on regulatory status, ownership, the trading model, expected volume, counterparties and the risk controls in place around execution.

Jurisdiction

Do KYB Requirements Change by Country?

Yes, in practice they often do — but not in a way that can be reduced to a fixed list per country. Providers may request additional documents based on the applicant's jurisdiction, ownership structure, regulated activities and risk profile. This applies whether the business is incorporated in or serving clients from the United States, United Kingdom, European Union / Cyprus, United Arab Emirates, India, or elsewhere.

A company incorporated in one jurisdiction but serving clients in several others will often face a more detailed review than a company operating in a single, well-understood market. Cross-border ownership, multiple licensing touchpoints and varying local documentation standards all add complexity. For jurisdiction-specific requirements, applicants should confirm directly with the relevant regulator, bank, payment provider or a qualified compliance professional, since local rules and provider policy can change.

Brokers vs prop firms

Are KYB Documents Different for Brokers and Prop Firms?

The core KYB categories — company identity, ownership, directors, business activity and source of funds — apply to both. Where the two differ is in emphasis, driven by how each business model handles client funds and payouts.

Area	Forex Broker	Prop Firm
Company documents	Standard KYB pack, often required by multiple counterparties	Standard KYB pack, scope depends on the provider involved
Ownership	Reviewed closely due to client-money exposure	Reviewed closely, particularly where payout obligations exist
Licensing	May hold a financial services license depending on jurisdiction and activity	Licensing status varies widely and depends on the specific model
Business model	Facilitates client trading on live or demo accounts	Evaluates trader performance and may fund successful traders
Client funds	Often holds or processes client deposits directly	Fund handling depends on whether challenge fees or live capital are involved
Trading activity	Executes or routes live client orders	May use simulated or funded live environments depending on the firm
Payout model	Client withdrawals from trading accounts	Profit-split payouts to evaluated or funded traders
Payment flows	Deposits, withdrawals, and often card or bank rails	Challenge fee payments and payout processing
KYC/AML	Applied to trading clients	Applied to challenge participants and funded traders
Risk controls	Focused on trading, custody and market conduct risk	Focused on payout risk, rule enforcement and account integrity
Source of funds	Reviewed for client deposits above certain thresholds	Reviewed for challenge fees and any funded-account arrangements
Technology provider requirements	Platform, CRM and liquidity integration documentation	Platform, CRM and payout-system integration documentation

This comparison is general in nature. Not every broker holds the same license, and not every prop firm operates under the same regulatory treatment — the exact requirements depend on how each business is structured and operates.

Organization

How to Build a Reusable KYB Document Pack

Because most companies go through KYB more than once — a new bank, a new PSP, a platform migration — it helps to organize documents into a structure that can be reused and updated rather than rebuilt from scratch each time.

01 Company
02 Ownership
03 Directors & UBOs
04 Regulatory
05 Business Model
06 AML / KYC
07 Banking
08 Source of Funds
09 Payment Providers
10 Technology
11 Supporting Documents

Within this structure, keep version control on documents that change over time, track expiry dates for anything time-sensitive, restrict access to a small group of authorized people, and use a consistent file-naming convention. A workable pattern looks like this:

Company_Registry_Extract_2026.pdf
UBO_Passport_[Name]_2026.pdf
Bank_Statement_[Company]_2026.pdf

Use this pattern as a naming convention only. Do not store or transmit actual personal identity documents through unsecured channels.

Process

KYB Readiness Workflow

KYB is usually iterative rather than a single upload-and-approve step. This is the general sequence most applicants go through.

Identify the provider

Confirm exactly which bank, PSP, platform or vendor will be reviewing the business, since each one weighs different categories differently.

Confirm the required document list

Ask the provider directly for their current document list rather than assuming this checklist covers every item they need.

Prepare company and ownership evidence

Assemble incorporation records, registry extracts, shareholder information and UBO documentation.

Prepare business and financial evidence

Gather business activity documentation, compliance policies and source-of-funds evidence relevant to the review.

Review consistency

Cross-check names, dates, addresses and ownership details across every document before submission.

Submit and respond to additional questions

Expect a follow-up round of questions and treat it as a normal part of the process rather than a sign of a problem.
