What a regulatory legal opinion is, and when you need one

A regulatory legal opinion is a written analysis by a lawyer qualified in a particular jurisdiction, addressing how that jurisdiction's law applies to a specific business described in specific terms. Businesses usually encounter one because somebody else has asked for it — a bank, a payment provider, an investor, a platform. Understanding what the document can and cannot do prevents both of the common mistakes: not obtaining one when it is the thing standing between you and an account, and treating one as a permission it never was.

Who asks, and why

Banks and payment providers

The most frequent reason. A financial institution onboarding a business in a sector that may be regulated has to satisfy itself that the client is operating lawfully. Where the activity is licensed, the licence answers the question. Where the activity is not subject to a licensing regime in that country, there is no document to produce — and the absence of one is difficult to evidence. An opinion from local counsel explaining why no licence is required, and on what legal basis, fills a gap that cannot otherwise be filled.

Platforms, processors and counterparties

App stores, acquirers, software vendors and B2B partners increasingly run their own compliance review before contracting. They are managing their exposure, not yours, and an opinion is the standard form in which the answer is accepted.

Investors

Due diligence on a business in a regulated or ambiguous sector will ask what legal basis it operates on. A considered opinion is a much better answer than a founder's assurance.

Your own decision-making

The most valuable reason and the least common. Before committing capital to a market, an opinion tells you whether the model is permissible, what it would take to make it permissible, or that it is not — which is worth knowing before the build rather than after.

What a proper opinion contains

• The facts it is given on, set out at length. The opinion is only as good as this section, and it will state that it assumes the facts are complete and accurate.
• The question, framed precisely. "Is this legal?" is not a question counsel can answer. "Does this activity, conducted in this way, require authorisation under statute X?" is.
• The legal framework — the actual statutes, regulations and, where they exist, decided cases and regulator guidance, cited so a reader can check them.
• The analysis, applying the framework to the facts, including where the position is arguable and what the counter-argument is. An opinion that concedes nothing is usually the weaker document.
• The conclusion, stated with whatever qualification it honestly needs.
• Assumptions, reservations and scope, including the date and the confirmation that it speaks only to the law of one jurisdiction.
• The signature of counsel admitted in that jurisdiction, in a form that identifies who is responsible for it.

What it cannot do

Four limits, all of which are routinely misrepresented when opinions are sold as products.

1. It is not a licence. An opinion that no authorisation is required is an analysis, not a permission. It confers nothing.
2. It does not bind the regulator. A regulator that takes a different view is not obliged to follow counsel's reasoning. A well-reasoned opinion is evidence that you took advice and acted in good faith, which materially affects how a disagreement is handled — but it is not a defence in itself.
3. It speaks to one jurisdiction only. This is the limit that causes the most damage. An opinion that a model is permissible in the country of incorporation says nothing about the countries where the customers are. If you accept customers in a market that regulates the activity, the opinion from elsewhere does not help you there.
4. It expires in substance, if not in form. It states the law as at its date. Legislation changes, guidance is issued, regulators shift position. An opinion several years old describing a fast-moving sector is a historical document.

Telling a real opinion from a letterhead

There is an established trade in short documents that look like opinions and contain no analysis — a paragraph asserting the activity is lawful, on the notepaper of a firm in the relevant country, sold at a fixed price with a fixed turnaround. Compliance departments have learned to recognise them, which makes them worse than useless: they cost money and mark the file.

What distinguishes the real thing:

• It engages with your actual facts. If counsel did not ask detailed questions about how the business works, the document cannot be about your business.
• It cites law you can look up. Named statutes and provisions, not general assurances about a jurisdiction's approach.
• It acknowledges difficulty. Genuine analysis identifies where the position is less certain. Unqualified confidence in an ambiguous area is a warning sign.
• Someone signs it. An identified lawyer, admitted locally, whose professional responsibility attaches to it.
• It is addressed. Often to you, sometimes to a named recipient who may rely on it. Reliance is a legal concept and it matters to whoever is reading.

Sectors where the question comes up

Anything involving payments or the holding of client funds. Crypto-asset services, where classification varies sharply between countries. Lending and credit. Gaming, betting and prediction markets, where the treatment of an activity can differ not only between countries but between states or provinces within one. Anything touching securities, where the question of whether an instrument is a security is frequently the whole issue.

These share a common feature: the answer genuinely depends on detail. Two businesses that describe themselves identically in a sentence can fall on opposite sides of a regulatory boundary once the mechanics are set out. That is precisely why the instrument exists, and why an opinion written without close attention to the mechanics is worthless.

How to commission one well

Write the description of the business yourself, in detail, before instructing anyone — the flow of funds, who contracts with whom, where the customers are, what is held and by whom, and what the business does not do. Then frame the question narrowly. Then instruct counsel qualified where the question arises, which is not necessarily where you are incorporated.

And be prepared for the answer to be unwelcome. An opinion commissioned to confirm a conclusion you have already reached is not an opinion; it is a purchase. The value of the instrument lies entirely in counsel's freedom to tell you the model does not work.
