The problem
Why the regulator step decides your closing date
Acquiring a licensed company is really two transactions running on different clocks. The commercial deal - valuation, due diligence, the share purchase agreement - moves as fast as the parties can push it. The regulator's assessment of you as the incoming controller moves at the pace the framework allows, and in every prior-approval regime it is the step that sets the closing date.
The published numbers understate this. A statutory window counts working days, not calendar weeks, and in most regimes it counts only the days when the regulator is not waiting on you. One incomplete answer can stop the clock entirely. That is why deals whose regulator step looked like "about two months" on paper routinely close later: the window measures the regulator's obligation, not your elapsed time.
We covered the mechanics of the process itself in our change-of-control guide. This article is the comparison layer: the same table we build at kick-off for every brokerage mandate - see how we run a mandate - showing what triggers the filing, how long the statute allows, and what actually stops the clock in each regime.

Prior approval
United Kingdom: the FCA's section 178 notice
The United Kingdom runs one of the clearest - and most scrutinised - regimes in this comparison. A buyer acquiring control of an FCA-authorised firm files a section 178 change-in-control notice before acquiring control, and the FCA's statutory assessment window is 60 working days.
Two qualifications matter. First, 60 working days is roughly twelve weeks of calendar time before anything goes wrong. Second, the window is interruptible: information requests from the FCA stop the clock, and it restarts only once the case officer has a complete answer. Market commentary reports real approvals often exceeding the statutory window, and interrupted clocks are the usual reason.
The practical consequence for deal planning is to treat 60 working days as the floor, not the estimate. A file that anticipates the FCA's questions - controllers mapped, funding evidenced, a coherent plan for the regulated business - protects the statutory pace. A file that answers questions reactively donates its own time back to the process.
Early engagement
Lithuania: qualifying holdings and the Bank of Lithuania
Under the EU framework that governs payment and electronic money institutions, acquiring a qualifying holding in a Lithuanian EMI or PI - thresholds start at 10% - requires prior notification to the Bank of Lithuania, and the assessment runs up to 60 working days.
As in the UK, the window is not a promise of elapsed time: the clock stops when the Bank of Lithuania issues a request for information and stays stopped until a complete reply lands. Buyers whose UBO chain or funding story generates questions can watch a 60-working-day assessment stretch well past its nominal end.
One feature distinguishes the Lithuanian process: pre-notification meetings with the regulator are common practice. Used well, they surface the difficult questions - group structure, source of funds, the acquirer's track record - before the statutory clock starts, so the formal assessment runs against a file the regulator has already seen the shape of. We build that meeting into the timeline for Lithuanian mandates rather than treating it as optional.
The outlier
Canada: FINTRAC has no window - and no shortcut
Canada is the outlier in this comparison: FINTRAC operates no prior-approval window for a change of control at all. Ownership changes must be reflected in the MSB registration, which must be kept current - the obligation is to update, not to ask permission first.
That makes the Canadian regulator step mechanically the shortest in the table, and it is one reason Canadian MSB acquisitions can move from signing to closing faster than their European equivalents. But zero window does not mean zero scrutiny. FINTRAC's review happens at registration, at renewal and through ongoing compliance - a buyer who treats the update as a formality and neglects the compliance programme simply meets the regulator later, on worse terms.
Two boundaries are worth marking. First, keeping the registration current is a continuing obligation, not a one-off filing at closing. Second, the Retail Payment Activities Act regime run by the Bank of Canada is a separate framework - an MSB registration update does not deal with it.
Crypto assets
MiCA CASPs: assessed before completion
For crypto-asset service providers authorised under MiCA, the qualifying-holding regime is written into the regulation itself. Articles 83 and 84 require notification of an intended acquisition to the national competent authority, and the notification is assessed before completion - you do not close and then inform; you inform, wait and then close. The assessment window runs up to 60 working days, in line with the wider EU framework, as of July 2026.
Because MiCA is applied by each member state's national competent authority, practice around information requests, early engagement and file expectations varies by member state. The regulation gives you the window; the authority's habits determine how the window behaves. For CASP acquisitions we scope the specific authority's approach at kick-off rather than assuming one national playbook travels to another.
Case-by-case
Dubai and Abu Dhabi: prior approval without a published clock
Dubai's VARA and Abu Dhabi Global Market's FSRA both require prior approval of a change in controller - on that point they sit with the FCA and the EU regimes, not with FINTRAC. What neither publishes is a one-size assessment window. As of July 2026 there is no statutory 60-working-day equivalent to plan around: the timeline is scoped case-by-case, shaped by the buyer's profile and the file in front of the regulator.
For deal planning this cuts both ways: there is no long statutory ceiling to fear, and no published floor to rely on. Our approach on UAE files is to treat the regulator step as an unscoped variable until it has been raised directly for the specific transaction - and to sequence the commercial timetable so that nothing irreversible happens before that conversation.
Red flags
What stretches every window
Strip away the differences between regimes and the same four problems drive almost every blown timeline we see. None of them is exotic, and none is unique to one regulator. All of them are visible - and mostly fixable - before the filing goes in.
-
Incomplete UBO chains
If the chain of ownership does not resolve to identifiable natural persons, the regulator will ask until it does. Every layer you cannot document quickly is a clock-stop waiting to happen.
-
Unexplained source of funds
It is not enough that the money exists; the regulator wants a coherent account of where it came from. Gaps here generate the slowest and most sensitive information requests in the process.
-
Group structures spanning uncooperative jurisdictions
When part of the structure sits somewhere the regulator cannot easily verify, the burden of proof shifts to you - and gathering that proof takes calendar time the statute does not count.
-
Slow responses to regulator questions
The one factor entirely inside your control. In clock-stopping regimes, every day an RFI sits unanswered is a day added to closing, working day for working day.
Before the clock starts
How to prepare before you file
-
Map the UBO chain to natural persons
Document every layer of ownership down to identifiable individuals before drafting the notification, not after the first information request.
-
Assemble the source-of-funds file
Build the evidence trail for the acquisition funding as a standalone pack the regulator can follow without needing to ask follow-up questions.
-
Pre-explain the awkward parts of the structure
If the group spans jurisdictions the regulator will find hard to verify, address that in the filing itself rather than waiting to be asked.
-
Use pre-notification contact where the regulator offers it
Pre-notification meetings are common practice at the Bank of Lithuania; where a regulator engages early, the formal clock runs against a file it already understands.
-
Assign RFI ownership before the filing goes in
Agree who drafts, who signs off and how fast. A response-time standard measured in days, not weeks, is the cheapest protection the statutory pace can get.
FAQ
Change-of-control timelines: common questions
Straight answers to what founders and buyers ask. If yours isn't here, ask us directly
01 Which regime is fastest for a buyer?
Mechanically, FINTRAC: there is no prior-approval window at all, so the regulator step does not gate closing - ownership changes are reflected in the MSB registration, which must be kept current. Among prior-approval regimes, the FCA, the Bank of Lithuania and MiCA national authorities all run statutory windows of up to 60 working days, with market commentary reporting real FCA approvals often exceeding the window. VARA and ADGM FSRA publish no one-size window as of July 2026, so "fastest" there depends entirely on your file.
02 Can I start operating while the assessment runs?
The company you are buying keeps operating under its existing ownership throughout the assessment - the licence does not pause. What you cannot do, in prior-approval regimes, is complete the acquisition before the regulator step concludes: the FCA's section 178 notice precedes acquiring control, MiCA notifications are assessed before completion, and VARA and ADGM FSRA require prior approval of the controller change. Under FINTRAC there is no prior-approval gate, but the registration must be kept current once ownership changes.
03 Do these windows apply to minority stakes?
Often, yes. Under the EU framework, qualifying-holding thresholds start at 10% of capital or voting rights, so a minority stake can trigger the Bank of Lithuania's prior notification, and MiCA's qualifying-holding regime works on the same logic. Thresholds and control tests differ between regimes, so we scope the trigger analysis at kick-off rather than assuming a minority purchase avoids the filing.
