How Banks in Sudan Handle a Customer Dispute (2026)

Most people only find out how a bank handles disputes at the worst possible moment — a transfer that left the account and never arrived, a financing instalment recorded twice, a balance that does not match what the branch said last week. In Sudan, that moment now usually arrives while the branch itself is hard to reach and the person who handled your file has moved cities.

The route through it is more structured than most customers expect. Sudan has a statutory complaints channel at the Central Bank of Sudan (CBOS), banks are required to run their own complaints units, and certain categories of dispute are pulled out of that system entirely and sent somewhere else by law. Knowing which track your problem sits on before you start saves weeks.

Start with your bank — the escalation depends on it

The Central Bank's complaint form asks, in as many words, whether you have already submitted the complaint to the bank or institution concerned. That question is the whole logic of the system in one line: CBOS is an escalation, not a first port of call. A complaint that arrives there having never been put to the bank is a complaint the bank has not yet had the chance to fix.

So the first step is a complaint to the bank itself, made in a way that leaves a record. A conversation at a counter is not a record. A written complaint — on paper with a stamped receipt, through the bank's app, or by email to the branch or head office — is. Whatever the channel, keep a copy of what you sent and the date you sent it, because that date is what you will be quoting later.

If your relationship with the bank runs mostly through an app rather than a branch, the in-app support log is often the cleanest evidence trail you have. Our guide to Bankak mobile banking covers where those records sit and how to pull them.

What the bank's own complaints unit is required to do

Under a Central Bank policy on strengthening banks' customer-protection policies and procedures, banks in Sudan are required to establish a unit or section for receiving and handling customer complaints — at head office and at branches, not only centrally. That is a regulatory obligation on the bank, not a courtesy.

The same framework describes complaint boxes at bank premises, emptied under the supervision of the general manager, and sets a handling period of not more than one month from the date the complaint is received. One month is the outer edge, not the target. If a month passes with no substantive answer, you have a concrete fact to escalate with: not "the bank ignored me", but "the complaint was submitted on this date and no decision was reported within the period".

Two practical cautions for 2026. First, confirm that the channel you are using is actually operating before you rely on it — a complaint box at a branch that is not functioning is not a route to anything. Second, if you have been displaced and are dealing with a different branch from the one that holds your file, say so explicitly in the complaint; it changes what the bank needs to look up. We cover that situation in more depth in what happens to your bank account if you're displaced.

Escalating to the Central Bank of Sudan

CBOS operates a consumer-protection department whose stated purpose is to maintain customers' rights and support public trust in the banking system. Its described functions are narrow and worth reading literally: it receives complaints from customers of banks and financial institutions, puts the details of the complaint to the party complained against, considers and decides the complaint once the information is complete, and reports the decision to the complainant.

Complaints can be submitted through several channels: the online form on the CBOS website, hand delivery at the Central Bank in Khartoum and in the states, by telephone on 0187056673, 0187056315 or 0187056889, and by post to the Central Bank of Sudan, P.O. Box 313.

Note what the description does not claim. It describes a decision reported to you — it does not describe a power to award you compensation or reverse a transaction. Treat CBOS as the body that puts an authoritative question to your bank and rules on it, and set your expectations accordingly. That is still worth a great deal, because a licensed bank answering the regulator behaves differently from a bank answering a customer.

That word "licensed" matters here, and it is the check that has to come first. The CBOS complaints channel covers banks and financial institutions under its supervision. If you handed money to something that was never licensed, this route does not help you — which is exactly why checking a bank or lender is licensed belongs before the money moves, not after.

What the complaint form actually asks for

Preparing the answers before you open the form makes the difference between a complaint that gets decided and one that stalls waiting for information. The CBOS form asks for:

• Your details — name, nationality, address, mail box, email, telephone and fax.
• The institution — the name of the bank or financial institution, the specific branch, and your account number.
• The complaint — a complaint type, and a written explanation of what happened.
• Your proposed remedy — how, in your view, the complaint could be resolved satisfactorily.
• History — whether you submitted the complaint to the bank first, and whether you have previously submitted the same complaint to CBOS.

You can attach supporting documents. The form accepts gif, jpg, jpeg, png, txt, pdf, doc and docx files under 2 MB each, and there is a CAPTCHA step before submission. Two megabytes is tight for phone photographs, so compress or crop screenshots before you upload rather than discovering the limit at submission.

The "proposed remedy" field is the one customers most often waste. "Resolve my problem" tells the reviewer nothing. "Reverse the duplicate instalment debited on this date and confirm the corrected balance in writing" is a specific, checkable outcome, and it frames the rest of the file.

The disputes CBOS will not take

The Central Bank states plainly that it does not consider complaints that have been filed to the courts. This is a genuine fork in the road, and it runs one way: once a matter is in litigation, the regulatory complaints channel closes to it.

The practical consequence is about sequencing. If you are weighing a court case, understand that starting one takes the CBOS route off the table for that dispute. For most everyday banking problems — a failed transfer, a disputed charge, an unexplained hold, a statement that does not reconcile — the complaint channel is faster, free, and does not require a lawyer. Save litigation for what the complaint process cannot reach, and take proper legal advice before filing.

When the dispute is about Sharia compliance

Every licensed bank in Sudan operates on Islamic principles, so a whole class of dispute exists here that does not arise in conventional systems: not "you charged me the wrong amount", but "this product should not have been structured this way at all".

Sudan handles that through a two-tier structure. Each bank maintains its own internal Sharia supervisory board that vets products and contracts, and above them sits the Supreme (High) Sharia Supervisory Board for Banks and Financial Institutions, which issues rulings on banking products and transactions. If your objection is genuinely about the structure of a contract rather than its execution, say so in the complaint in those terms — it routes the file differently inside the bank. How Sharia boards approve financial products explains how that approval chain works, and Islamic banking basics covers the underlying contracts.

Be honest with yourself about which one you have. Most disputes that feel like Sharia-compliance objections are ordinary execution errors — a markup applied differently from the signed schedule, for instance. That is a contract-performance complaint, and it is easier to win.

Financed property and mortgaged assets: arbitration, by law

Here is the rule that catches people out. Sudan's 1990 statute on property mortgaged to banks makes referral of any dispute regarding assets mortgaged to banks to arbitration mandatory. Not optional, and not a clause you negotiated — a statutory route.

Arbitration generally in Sudan is governed by the Arbitration Act 2016, which covers both domestic and international arbitration. Applications connected to an arbitration go to the court that would have had jurisdiction over the dispute had it not been referred.

If you are in dispute over a home or vehicle acquired through bank financing, and the asset is mortgaged to the bank, the general complaints route is not where that ends up. Get legal advice specific to that track early, because it has its own timetable and its own costs. Murabaha home and vehicle finance, worked through sets out how those agreements are built and where the pressure points sit.

Investment deposits and the force-majeure ruling

One dispute has been unusually common since 2023: a customer with an investment deposit wants their money out, and the bank says it cannot.

The Supreme Sharia Supervisory Board for Banks and Financial Institutions addressed this directly in a ruling issued on 14 February 2024, on a question submitted by the Sudanese French Bank through the CBOS governor. The reasoning follows from what an investment deposit actually is. Because the bank acts as the manager of the investment rather than a borrower, it does not guarantee either the original amount or a profit. Where financing portfolios have been destroyed and the funds genuinely lost, the ruling held that deposit owners cannot simply demand withdrawal, and that banks may draw on investment-risk reserves to offset losses. Profits already earned may be paid out in instalments, supported by profit-rate reserves, and banks may spread losses over several years to allow their position to recover. The board summed up the principle as force majeure affecting how obligations are met rather than whether they exist.

That is an uncomfortable answer, and it is a real one. It is also the single clearest illustration of why an investment deposit is not a savings account with a better return — the risk-sharing is the product. If you are choosing between deposit products now, comparing profit-sharing savings products walks through what you are actually agreeing to, and you can browse current options through bank accounts.

This ruling dates from early 2024. Confirm the current position with your bank's Sharia board or CBOS before relying on it.

Separately, the Deposit Guarantee Fund Act appears on the CBOS list of banking laws, so a deposit-guarantee framework exists in Sudan. No current coverage figure could be established from a primary source, and any older Sudanese pound amount would be meaningless after devaluation — ask CBOS directly rather than trusting a number you find online.

When the problem is paperwork, not the bank

A growing share of 2026 "disputes" are not disputes at all. They are accounts that stopped working because customer records are out of date.

CBOS has been running a customer data-update requirement tied to anti-money-laundering and counter-terrorist-financing standards, alongside the SudaPass digital identity system, and in August 2026 extended the deadline for customers to complete it to the end of the year — explicitly to accommodate customers whose circumstances make it hard. If your access has been restricted, check whether your file is simply incomplete before you file a complaint. Bringing your records up to date is a far shorter path than a month-long complaint process, and it is the more likely explanation. Our guide to opening a bank account in Sudan lists the documentation banks generally expect.

Building a file that gets decided

Whichever track your dispute sits on, the same discipline decides it:

• Fix the timeline. Dates, amounts, reference numbers, branch names, in order. A reviewer who can follow the sequence can rule on it.
• Keep the evidence at the time. Screenshots of app confirmations, transfer references, SMS notifications, signed schedules. Retrieving these later is much harder than saving them now.
• Quote the document, not your memory. "The signed schedule states X, the account shows Y" is a complaint. "They said something different" is not.
• Ask for one specific outcome. Vague requests get vague answers.
• Escalate on a date, not on a feeling. Complain to the bank, note the date, and if the month passes without a decision, escalate citing that fact.

Do not send original documents anywhere. Send copies, and keep the originals — displacement has already cost many Sudanese households their paperwork once, and a dispute file is not worth risking them a second time.

Frequently asked questions

Do I have to complain to my bank before going to the Central Bank? The CBOS form asks whether you have, which makes the expectation clear. Complain to the bank first, in writing, and keep the date. If nothing is resolved, escalate — and say in the form exactly when you first complained.

How long should a complaint take? The framework for banks' complaint units sets a handling period of not more than one month from the date the complaint is received. Treat that as the point at which you escalate, not as a normal waiting time.

Can I complain to CBOS if I have already gone to court? No. The Central Bank states that it does not consider complaints filed to the courts. Choosing litigation closes the regulatory route for that dispute, so decide the sequence deliberately.

What if my dispute is about a house or car financed by the bank? If the asset is mortgaged to the bank, Sudan's 1990 statute on property mortgaged to banks makes referral of the dispute to arbitration mandatory, with arbitration itself governed by the Arbitration Act 2016. That is a different track from the complaints channel, and it warrants legal advice.

My bank will not release my investment deposit. Is that allowed? Possibly. An investment deposit is a risk-sharing product, and the Supreme Sharia Supervisory Board ruled in February 2024 that where financing portfolios have been lost, holders cannot simply demand withdrawal, though earned profits may be paid in instalments. Ask your bank to explain in writing which reserves and instalment arrangements it is applying, and confirm the current position with CBOS.

What if the institution I dealt with was not a licensed bank? Then the CBOS complaints channel, which covers supervised banks and financial institutions, is unlikely to help. Check licensing before money moves — the CBOS commercial-bank locator exists for exactly that.
