Why the lender wants the donor's source of funds, not just yours
When a lender accepts a gifted deposit, its compliance file has to be able to answer one question on the record: where did this money come from, and is it clean? A gift letter alone does not answer it — a letter says the money is a gift, but says nothing about whether the donor genuinely had it or how they came by it. So lenders that take gifted funds routinely ask the donor for proof of identity, bank statements and evidence that the money was legitimately obtained.
For a donor in India, that evidence is exactly what an overseas underwriter cannot assess on their own. Indian bank statements in rupees, a return filed on the income tax portal, an old property sale deed — these do not read the way the lender's system expects, and the underwriter has no way to judge whether they add up. A chartered accountant's certificate fills that gap. It states the donor's income and net worth, traces the gifted amount to a specific, documented source, and confirms it reconciles to the donor's filed returns and records, so the lender is relying on a regulated professional rather than a stack of papers it cannot interpret.
The piece that makes the certificate usable across the border is the UDIN. ICAI requires its members to generate an 18-digit Unique Document Identification Number on certificates, and the lender's team can check it on ICAI's public portal to confirm the document is genuine. That is what turns an Indian certificate into something a foreign mortgage file will accept.
How this differs from the bank's frozen-transfer query
It is worth being clear about which problem this page solves, because there is a closely related one that needs a different document.
Where money has already been wired abroad and a bank has frozen it pending proof of origin, the certificate is about the recipient's transfer and the bank's compliance hold — covered by our source-of-funds certificate for a foreign bank's AML query. This page is the earlier, donor-side version: the gift has not necessarily moved yet, the question is asked by the mortgage lender as part of approving the loan, and the focus is the donor's own income, net worth and where their money came from — the evidence that sits behind the gift letter.
It is also distinct from certifying your own Indian rental or business income so the lender can count it in your borrowing capacity. There, the income is yours and feeds the debt-to-income calculation; here, the money belongs to the donor and the point is to prove the deposit is a clean gift, not to add to what you earn. The three certificates often appear in the same house purchase, which is why they cross-reference each other rather than overlap.
Tracing the gifted funds to a clean source
The donor's money usually traces back to one of a few origins, and the CA evidences each one differently so the certificate shows a path rather than an assertion.
| Source of the gift | What the CA ties it to |
|---|---|
| Accumulated savings | Years of the donor's filed ITRs, bank and FD statements |
| Property sale | Sale deed, capital gains in the donor's return, TDS paid |
| Inheritance or matured investment | Will / succession papers, maturity records |
For accumulated savings, the certificate shows the gift comes out of wealth built up over years of declared income, drawing on the donor's successive returns and the statements behind them. For a property sale, it links the sale deed and the gains declared in the donor's return to the funds now being gifted. For an inheritance or a matured policy or deposit, it ties the money to the will, succession certificate or maturity record and explains it as existing assets, not fresh unexplained income.
Alongside the source, the certificate certifies the donor's net worth — assets minus liabilities as on a recent date — so the lender can see the gift is comfortably within the donor's means and not the donor's entire savings stripped bare. That combination, source plus means, is what an AML reviewer is really testing.
Where LRS comes in if the donor remits the gift
If the donor is a resident of India and actually sends the gifted money abroad themselves, the remittance runs under the Reserve Bank's Liberalised Remittance Scheme (LRS), which lets a resident individual remit up to USD 250,000 per financial year for permitted purposes, including a gift to a relative. The gift has to sit within that annual limit, and the donor's bank handles the remittance through the usual authorised-dealer process.
Where the remittance is one on which a CA certificate is required — typically a payment to a non-resident routed through Form 15CA / 15CB — a chartered accountant issues that certificate too, so the outward transfer and the source-of-funds story are consistent. Not every gift remittance needs Form 15CB, and the deposit may instead move from the borrower's own existing overseas or NRE funds, so we scope this to how the money is actually travelling rather than assuming the LRS route applies.
The LRS limit, the purpose code and the bank's remittance formalities are governed by Indian exchange-control rules and the donor's bank; the lender abroad cares about the gift being clean and within the donor's means. The certificate is built so both sides see the same documented picture.
A worked example: an NRI's parents funding a Sydney deposit
Karthik, an NRI in Sydney, is buying his first home there. He has the income to service the loan, but the deposit is coming from his father in Chennai as a gift. The Australian lender's checklist says it will accept gifted funds against a signed gift declaration plus "evidence of the donor's source of funds, certified by an accountant".
A chartered accountant works from the father's last few filed returns, his Form 26AS, and the bank and fixed-deposit statements behind the gifted amount. The father's money is long-standing savings out of his salary and a matured fixed deposit, so the CA issues one certificate setting out the father's income and net worth, confirming the gifted sum comes from those accumulated, declared funds, and naming the records relied on. It goes out on the CA's letterhead with an 18-digit UDIN. Because Karthik's father is remitting the money from India himself, the CA also makes sure the outward remittance sits within the LRS limit and that any Form 15CA / 15CB the bank needs lines up with the same figures.
Karthik and his father sign the lender's gift letter, and the certificate goes into the file behind it. The lender's team verifies the UDIN on ICAI's portal, sees the donor's source and means evidenced against the Indian tax record, and clears the gifted deposit. Exactly what each lender wants — how many years of donor statements, how recent, whether a separate seasoning period applies — varies by lender and country, so the certificate is built around that lender's specific checklist rather than a generic template.
