The recent lump sum
A large amount that appeared a few weeks before the application, with nothing before it. From a compliance point of view this is the least explained money possible, regardless of where it actually came from.
Every bank account, every investor route and most large transfers come with the same question: where did this come from. A statement showing a balance answers half of it. The other half — how the balance came to exist — is where applications stall, and it is answered with documents, not assurances.
Most refusals come from the last two, not from the amount.
| Source | What is usually accepted | Weak spot |
|---|---|---|
| Employment income | Contract, payslips, statements showing regular credits | Cash salary with no bank trail |
| Business income | Company accounts, dividend resolutions, tax filings | Company with no filings or no substance |
| Sale of a company | Sale agreement, completion documents, receipt of proceeds | Agreement without proof the money actually arrived |
| Sale of property | Title record, sale contract, settlement statement | Price in contract far from market value |
| Inheritance | Will or succession certificate, probate documents | A statement from a relative and nothing else |
| Gift | Gift deed plus the giver's own source of funds | Documenting the gift but not the giver |
| Investment returns | Broker statements over a period | A single screenshot of a portfolio |
Four patterns, and none of them are about having too little money.

Stated salary of one size, transactions of another. Inconsistency between what you say you do and what the account shows generates questions faster than any single red flag.
Money that moved through several accounts and jurisdictions with a gap somewhere. Every hop needs to be visible; the missing one is the one that will be asked about.
A letter saying the funds are legitimate is not evidence. Contracts, statements, filings and registries are. The difference matters more than the volume of paper.
The work is mostly ordering what already exists, not producing something new.
Build the story forward: how the wealth was generated, then how it turned into the funds now being used. A file that starts with the current balance and works backwards always reads as defensive.
Statements for a continuous period, not selected months. Gaps get noticed, and an unexplained gap costs more time than whatever it contained.
Amounts in contracts should reconcile with credits in statements, allowing for fees and exchange. Where they do not, explain the difference before being asked.
Documents in other languages need translation, and official documents often need legalisation in the issuing country. This takes weeks and is the usual reason a file sits unfinished.
One page explaining who you are, what you do, where the money came from and what each attachment shows. Reviewers read hundreds of files; making yours easy to follow is a practical advantage.
They are normal and not a sign of suspicion. What matters is answering fully and quickly: a week of delay on your side routinely becomes a month on theirs.
It varies by institution, but a continuous recent period is standard, and larger amounts attract longer look-backs. Providing more than asked rarely hurts; providing less always slows things down.
Cash with no banking history is the hardest thing to evidence. It is not automatically rejected, but it requires documentation of the underlying transaction, and often that documentation does not exist.
Increasingly it is examined rather than dismissed, but it requires exchange records, wallet history and evidence of the original fiat purchase. Expect more questions, not fewer.
Then the business itself has to be evidenced: registration, accounts, your role and the mechanism by which value reached you. This is a larger file, and it is worth assembling before applying.
No. A professional letter can summarise and explain, which helps, but it does not substitute for the underlying records it refers to.
Write rather than call: describe in a message where the funds came from and what documents you already hold, and you get back a list of what is missing and what to request first. Attachments stay with the thread, and the list is something you will work through over weeks.
