FIDUCIARY DUTIES

- Fiduciary obligation: A Fiduciary is someone who undertakes to act for or on behalf of
another, irrespective of remuneration and whether or not the other party asked [Bristol
and West Building Society v Mothew].
STEP 2: IDENTIFY (for structural purposes) POTENTIALLY LIABLE PARTIES

NO Fiduciary Relationship in Russel v Cartwright [2020] – Fiduciary duties do not usually arise
in commercial relationships because each party is entitled to prefer its own interests

Building Society v Mothew]

- Company Act 2006
- Article 170: Scope and nature of General duties
- Article 172: Duty to promote the success of the company
- Article 174: Duty to exercise reasonable care, skill and diligence
- Article 175: Duty to avoid conflicts of interest
