Many business owners assume that only formally appointed board directors carry legal risk. In practice, certain individuals who have not been formally appointed to be the board can in certain situations be treated as directors, and they face the same duties and potential liabilities as formally appointed directors.

This insight discusses the hidden risks where an individual may “act” as a director of a company but has not been formally appointed as such.

Statutory meaning of “director”

There is no strict definition of a director in the Companies Act 2006, just a provision that the term director “includes any person occupying the position of director, by whatever name called” (section 250 Companies Act 2006).

In this insight, a “director” refers to the formal office of a statutory company director, as opposed to someone with “director” in their job title, but who does not carry out any management or board level functions.

Three concepts are key: de jure directors, de facto directors and shadow directors.

De jure director

A de jure director is a person who has been formally appointed as a director and who is required to be registered as a director at Companies House.

De facto director

A de facto director is someone who has in practice assumed responsibility for acting as a director, despite not being formally appointed. This might include a founder who has “stepped back” but continues to make key decisions, or a senior executive operating at board level. If they are seen to perform the functions of a director, the law may treat them as one.

Shadow director

A shadow director is a person in accordance with whose instructions the directors of the company are accustomed to act. This can include dominant shareholders, or even trusted advisers who become too involved in decision-making, although professional advisers are excluded from being shadow directors.

Why does this matter?

If a person is deemed to be a de facto and/or a shadow director, they will have certain statutory directors’ duties under the Companies Act 2006, as if they were de jure directors. These duties include a duty to act in the company’s best interests and to avoid conflicts.

In certain situations, de facto and/or shadow directors may be held to be personally liable, for example in a wrongful trading in an insolvency scenario, and de facto and/or shadow directors may be subject to potential directors’ disqualification proceedings.

Common scenarios where the risk of an individual being deemed to be acting as a de facto or shadow director include:

founders informally directing decisions after resigning as directors;
having a senior management team whose decisions are followed by the company, although the individuals on the management team are not de jure directors;
majority shareholders overriding the board;
external (non-professional) advisers becoming deeply involved in strategic decisions.

Practical steps to manage risk

Companies should:

clearly document who is making decisions and in what capacity;
ensure the board retains and exercises independent judgment;
keep advisory roles firmly separate from decision-making;
regularly review governance arrangements, especially during growth or restructuring; and
consider appointing individuals as de jure directors, if appropriate.

For SME owners, the key takeaway is simple: legal responsibility follows influence and behaviour, not just job titles.
