Company documents guide
Articles of association and shareholders’ agreements are often confused, but they do different jobs. Articles are the company’s public constitutional rules. A shareholders’ agreement is usually a private contract that deals with the commercial relationship between shareholders.
Quick answer
Articles are mandatory public company rules. A shareholders’ agreement is usually an optional private contract for the shareholders’ commercial arrangements. They should work together. Where the documents overlap or conflict, advice may be needed.
Mandatory constitutional rules
Usually optional private contract
They should work together. Where provisions overlap, consistency matters. Some share-related rights or restrictions may need to be reflected in the articles as well as the shareholders’ agreement.
Articles
Articles are constitutional company rules, not a full commercial founder or shareholder arrangement. Model articles are the standard default articles a company can use, but they may not answer every practical question between shareholders.
director powers and decision-making
shareholder resolutions
share rights and classes
issue and transfer of shares
pre-emption mechanics where included
dividends and distributions
meetings and voting
appointment and removal of directors
administrative rules
model articles default position
Shareholders’ agreement
A shareholders’ agreement is commonly used to regulate the private relationship between shareholders and sometimes the company, especially where commercial terms should not sit entirely in public articles.
reserved matters
voting thresholds
board and director appointment rights
share transfer restrictions
good leaver / bad leaver
drag-along and tag-along
deadlock
valuation and buyout
dividend expectations
funding obligations
confidentiality
restrictive covenants
dispute resolution
deed of adherence for new shareholders
Why both
A company can have articles without a shareholders’ agreement, but where there is more than one shareholder, articles may not fully address the private commercial arrangements shareholders care about.
Equal ownership can stall decisions. A shareholders’ agreement can set reserved matters, escalation steps and deadlock mechanics.
Investors may expect information rights, vetoes, consent thresholds, transfer controls and exit protections that model articles may not cover in enough detail.
Private rules can help with family exits, dividend expectations, valuation, transfers on death or retirement and dispute handling.
The company may need separate rules for employment, directorship, share ownership and what happens if the person leaves the business.
A passive shareholder may need clarity on information rights, dividends, reserved matters, transfers and when consent is required.
Confidentiality, restrictive covenants and business opportunity wording can be important where a shareholder has access to sensitive commercial assets.
Drag-along rights, tag-along rights, transfer controls and clean adherence processes can matter before an investor round or sale process.
Different cash, time, asset or expertise contributions can create mismatched expectations unless decision-making, funding and exit rules are written down.
Leaver wording and valuation mechanics can reduce uncertainty if a founder stops working in the business but still holds shares.
Conflicts
The documents should be drafted to be consistent. A shareholders’ agreement may create contractual obligations between parties, but company actions may also need to comply with the articles and company law.
Important
Do not assume a private shareholders’ agreement fixes public constitutional mechanics if the articles say something different.
Private terms
Shareholders’ agreements are useful for sensitive commercial terms shareholders may not want in public articles. Some rights or restrictions may still need to be reflected in the articles to be fully effective.

Common mistakes
relying only on model articles
assuming a shareholders’ agreement replaces articles
adding conflicting provisions
putting sensitive commercial terms in public articles unnecessarily
failing to update articles after agreeing shareholder terms
forgetting a deed of adherence for new shareholders
ignoring 50/50 deadlock
no clear leaver or valuation wording
not checking pre-emption rights
using investor-style clauses without understanding them

Articles of association are mandatory constitutional rules for the company and are filed or available publicly through Companies House.
