02 / In plain words
What Fiduciary means
A fiduciary is someone who is obliged to act in the interests of another person, not in their own. This is not simply a contractor under an agreement: a fiduciary bears a heightened standard of liability known as fiduciary duties.
There are several main duties. Loyalty — putting the client’s interests above one’s own. Reasonable care and prudence — acting with due care, as a reasonable professional would. Disclosure of conflicts of interest — if they arise, they must be reported, not kept quiet. A prohibition on hidden benefit — no undisclosed commissions and no use of information for personal ends.
This role is held by trustees, members of foundation councils, asset managers and, in some legal systems, company directors in relation to the company itself. For the client, the practical point is simple: understand which of your counterparties bear fiduciary duties and which are simply providing a service and selling you a product.
A case from practice
A client was offered an investment solution, and the adviser’s remuneration depended on the sale of a particular product. A question about the payment model, asked at the start, immediately made clear whose interests stood behind the recommendation.

04 / How it works
How to check a counterparty
Understand their role and status
Who you are dealing with: a manager, an adviser or a seller.
Confirm whether they have fiduciary duties
Whether they have a duty to act in your interest.
Review their remuneration model
Who pays them and for what.
Request disclosure of conflicts
Written disclosure of links to products and sellers.

05 / Key facts
What you need to know
01Who it is
A person with a higher duty
A trustee, a foundation council member, an asset manager, and in some countries a company director.
02Duties
Loyalty and care
Act in the client's interest and with the care a reasonable professional would take.
03Prohibitions
Hidden gains and conflicts
No undisclosed commissions. Conflicts of interest are disclosed, not concealed.
04Not everyone
An adviser is not always a fiduciary
Many simply sell a product. The status depends on the role, the contract and the country's law.
Common mistakes
Assuming any adviser is on your side
Ask directly whether they owe you fiduciary duties.
Not finding out who pays the adviser
Learn the fee model: paid by you or by the product seller.
Relying on verbal assurances
Put the duties and conflict disclosure in the contract.
06 / Expert advice

How to prepare in advance
When choosing a manager or adviser, two things are established: whether they bear fiduciary duties and how they earn their money. A fee from you and a commission from the product seller are fundamentally different models, and the second creates a conflict of interest. Duties and the procedure for disclosing conflicts are recorded in the contract.
What we do for you. We advise always asking advisers how they earn their money. It is a simple question that explains a great deal — both in investment and in the immigration sphere, where remuneration is also structured in different ways.
