Doctrine of Ultra Vires and Constructive Notice Explained

Updated 11 October 2026 · Fact-checked

An act is ultra vires when it goes beyond the powers the company's memorandum gives it. Such an act is void and cannot be ratified. Constructive notice presumes outsiders know the public documents. Indoor management protects outsiders from internal irregularities. To solve a question, test the act against the objects, then the outsider's position.

Understand Doctrine of Ultra Vires and Constructive Notice

A company is an artificial person. It has only the powers its memorandum of association gives it. Ultra vires means "beyond the powers". If a company does something outside its objects, the act is ultra vires the memorandum.

The classic effect is that an ultra vires act is void and not binding on the company. Even all the members together cannot ratify it, because the company never had the capacity to do it. A contract made outside the objects cannot be enforced by either side. The company cannot sue on it and the outsider cannot sue the company on it. The outsider may, however, have remedies such as an injunction, recovery of money or property by tracing, or action against directors who misapplied funds. Do not confuse this with an act that is within the objects but beyond the articles or the directors' authority. That is intra vires the company but irregular, and members can ratify it by the proper procedure.

The doctrine protects two groups. Shareholders are protected because their money is used only for the stated business. Creditors are protected because the capital is not spent on unrelated ventures. Members can also seek an injunction to stop an ultra vires act before it is carried out. Directors who commit the company to an ultra vires act may be personally liable for any loss to the company, and they may also be liable to the outsider for breach of warranty of authority.

Outsiders need protection too, so two further doctrines apply. Constructive notice says that the memorandum and articles are public documents kept with the Registrar. Anyone dealing with the company is treated as having read them and understood them, whether or not they actually did. So an outsider cannot say they did not know about a limit in these documents. This doctrine works against the outsider.

The doctrine of indoor management works in favour of the outsider. The outsider is entitled to assume that the company has followed its internal procedures, such as holding meetings and passing resolutions. The outsider need not investigate internal matters. Constructive notice covers what is in the public documents. Indoor management covers what happens inside the company. Indoor management does not help in some cases, which are listed in the formulas section. In this topic the Companies Act, 2013 text supplied to you does not deal with ultra vires directly, so state these doctrines as settled principles and do not quote a section for them.

Key rules to remember

Ultra vires act: Act beyond objects in the memorandum → void, cannot be ratified, not enforceable; Not even a unanimous vote of members can validate it.
Intra vires but irregular act: Within objects but beyond directors' authority or procedure → can be ratified by members; Ratify through the procedure the articles or the Act require.
Constructive notice: Outsider is deemed to know the memorandum and articles, which are public documents; It covers the content of public documents, not the internal working of the company.
Doctrine of indoor management: Outsider dealing in good faith may presume internal formalities were complied with; It protects the outsider and acts as a limit on constructive notice.
Exceptions to indoor management: No protection where: (1) outsider had actual knowledge of the irregularity; (2) outsider was put on inquiry by suspicious circumstances; (3) the document is forged; (4) the act is beyond the public documents themselves; A forged document is void, so there is nothing to presume. Dealing as an insider, such as a director, also weakens the protection.
Link between the two doctrines: Constructive notice: check the public documents. Indoor management: do not check internal procedure.; Use this one-line contrast in the difference questions.

How to solve Doctrine of Ultra Vires and Constructive Notice questions

Use this method for any problem or theory question on ultra vires, constructive notice or indoor management.

1Identify the act and the parties: the company, its officers and the outsider.
2Read the memorandum's objects given in the facts. Decide whether the act is within or outside them. Ultra vires needs a gap between the act and the objects.
3If the act is outside the objects, state the rule: the act is void, cannot be ratified and cannot be enforced either way. Then note the remedies, such as an injunction for members, tracing of property and action against directors.
4If the act is within the objects but the authority or procedure was defective, call it intra vires but irregular. Then move to indoor management.
5Apply constructive notice: could the outsider have found the limit in the memorandum or articles? If yes, the outsider is bound by it.
6Apply indoor management: was the defect internal? Was the outsider in good faith? Check each exception: actual knowledge, suspicion, forgery, or the outsider being an insider.
7Write the conclusion clearly: is the contract binding on the company, and what remedies exist? Name the doctrine you relied on.

Quickest way: Two-question test

When to use it: Use this when you have only a few minutes for a short case-based question.

Ask: is the act within the objects? If no, it is ultra vires and void. Write the conclusion and the remedies.
If yes, ask: did the outsider know or suspect the defect, or is the paper forged? If no to all, indoor management protects the outsider and the company is bound.
If the outsider knew or suspected, or the document is forged, the company is not bound.
Close with one line naming the doctrine and the conclusion.

Common mistakes in Doctrine of Ultra Vires and Constructive Notice

Saying members can ratify an ultra vires act by a special resolution.
Students mix it up with acts that are only irregular, which members can ratify.
Fix: Remember that ultra vires the memorandum means no capacity, so the act is void. Only an alteration of the objects, done properly beforehand, can change the position going forward.
Treating constructive notice and indoor management as the same thing.
Both deal with what an outsider knows.
Fix: Constructive notice binds the outsider to public documents. Indoor management lets the outsider ignore internal irregularities. They work in opposite directions.
Applying indoor management where the outsider had real knowledge of the defect.
Students memorise the rule and skip the exceptions.
Fix: Always scan the facts for actual knowledge, suspicious circumstances, forgery and insider dealing before you apply protection.
Saying the outsider can enforce an ultra vires contract against the company.
Students assume fairness to the outsider overrides the objects.
Fix: Say the contract is void and unenforceable by either side. Then list the outsider's other remedies, such as recovery of money or property and a claim against the directors.
Confusing an act beyond the articles with an act beyond the memorandum.
Both are described loosely as being beyond the company's powers.
Fix: Beyond the memorandum is ultra vires and void. Beyond the articles is a defect that can be cured by altering the articles or by ratification.
Giving a section number for the doctrine of ultra vires.
Students try to cite the Act for every answer.
Fix: These are judge-made doctrines. Link them to the memorandum and articles in general terms and cite a section only when you are sure of it.

Worked examples

Example 1

The objects clause of Kisan Agro Foods Ltd permits it only to process and sell agricultural produce. Its directors, with the unanimous consent of all members, buy a hotel for ₹4,00,00,000 from Mr Rao. Can the company be held to the contract? Can the members ratify it?

Show the solution

Identify the act: buying a hotel. The objects permit only processing and selling agricultural produce.
Compare: running a hotel is outside the objects. The act is ultra vires the memorandum.
Apply the rule: an ultra vires act is void. It cannot be ratified even by all members, because the company has no capacity.
Constructive notice: Mr Rao is treated as knowing the objects clause, which is a public document. He cannot plead ignorance.
Remedies: a member may seek an injunction to stop the purchase. If money was paid, the company may trace and recover it, and directors who misapplied funds may be liable to the company.

Answer: The contract is void and not binding on the company. Unanimous consent of the members cannot ratify it. Mr Rao cannot enforce it because he had constructive notice of the objects.

Example 2

The articles of Sundar Textiles Ltd allow the directors to borrow money only if the general meeting has passed a resolution authorising it. The managing director borrows ₹10,00,000 from Mr Iyer, a stranger, without any such resolution. Mr Iyer did not inspect any company record. The company refuses to repay. Decide.

Show the solution

Check the objects: borrowing is within the company's powers. The act is not ultra vires the memorandum.
The defect is internal: the resolution required by the articles was not passed. The act is intra vires but irregular.
Constructive notice: Mr Iyer is deemed to know the articles. He therefore knows that a resolution is needed.
Indoor management: he is not expected to check whether the resolution was actually passed. He may presume the company complied.
Exceptions: nothing in the facts shows he knew of the missing resolution, was put on inquiry, or relied on a forged paper. He acted in good faith.

Answer: The company is bound and must repay the ₹10,00,000. Constructive notice only told Mr Iyer that a resolution was needed. Indoor management allows him to assume it was passed.

Exam tips

Start every answer with the rule in one line, then apply it to the facts, then conclude. This is the ICSI answer style.
In a case question, first decide whether the act is beyond the memorandum or only beyond the articles or authority. Marks depend on this split.
Always list the exceptions to indoor management. Examiners usually reward each exception you name and apply.
For the difference question, give four or five points side by side in sentences: meaning, basis, who it protects, effect on the outsider and scope.
Do not quote a section for these doctrines unless you are certain. A wrong section number costs marks.

Practice questions from Memorandum and Articles of Association and its Alteration

Doctrine of Ultra Vires and Constructive Notice: frequently asked questions

What is the effect of an ultra vires act of a company?

The act is void and not binding on the company. Members cannot ratify it, and neither side can enforce the contract. Members may seek an injunction, and the company may recover its money or property and act against directors who misapplied funds.

What is the difference between constructive notice and indoor management?

Constructive notice presumes an outsider knows the contents of the memorandum and articles. Indoor management lets the outsider presume internal formalities were followed. The first works against the outsider, and the second protects the outsider.

What are the exceptions to the doctrine of indoor management?

The outsider gets no protection where there was actual knowledge of the irregularity, where suspicious circumstances called for inquiry, or where the document was forged. Protection is also weak where the outsider is an insider, such as a director, who can be expected to know the internal position.

Can a company ratify an act that is only beyond the articles?

Yes. If the act is within the objects but beyond the articles or the directors' authority, members can ratify it by the proper procedure. The articles can also be altered. This is different from an act beyond the memorandum, which is void.
