Concealment
The deliberate hiding or suppression of a material fact that one party has a duty to disclose; active concealment constitutes fraud.
While straightforward in theory, many businesses fail to actively track obligations tied to this concept - often resulting in missed deadlines, unintended renewals, penalties, or loss of contractual rights.
US Law · For business owners and foundersWhat is a Concealment?
Concealment is the deliberate hiding or suppression of a material fact that one party has a duty to disclose. Active concealment - actively hiding the fact or taking steps to prevent the other party from learning it - constitutes fraud. Passive concealment (simply remaining silent about a fact) is generally not fraud unless a duty to disclose existed.
Concealment is actionable fraud if: (1) a material fact existed; (2) the party knew of the fact; (3) the party had a duty to disclose; (4) the party intentionally concealed or hid the fact; and (5) the other party was injured by reliance on the concealment. The key distinction is active (fraud) versus passive (generally not fraud) concealment.
In practice, many teams rely on a contract expiry tracking system to stay on top of dates and obligations tied to clauses like this.
Key Elements
Material Fact
The concealed fact must be material - important to the decision to contract. A material fact is one that would likely influence a reasonable person's decision. A material defect in property sold, a known risk, or a false qualification are material facts.Knowledge of the Fact
The party concealing must know of the fact. Concealing something you do not know about is not fraud. If you sell property and genuinely do not know of a hidden defect, you cannot be liable for concealing it (though you may be liable for negligent misrepresentation or breach of warranty).Duty to Disclose
A duty to disclose arises in certain contexts: (1) fiduciary relationships (attorney-client, agent-principal); (2) professional relationships with expertise (architect, home inspector); (3) direct inquiry (if asked directly, silence is concealment); (4) known defects in real estate (in many states, seller must disclose known defects).Active Concealment
Active concealment involves affirmative steps to hide a fact: falsifying documents, destroying evidence, deliberately misleading, or creating false impressions. Simply remaining silent is passive concealment and generally not fraud.Reliance and Injury
The other party must rely on the concealment (or absence of disclosure) and suffer injury. If the party would have discovered the fact through reasonable investigation, reliance may not be justified.Real-World Example
HomeSeller sold property to Buyer, concealing a known foundation crack that had been professionally repaired years earlier. HomeSeller painted over cracks and did not disclose the repair. Buyer discovered the issue after closing and sued for fraud.
This is active concealment and fraud. HomeSeller knew of a material fact (the foundation issue and past repair), had a duty to disclose (most states require sellers to disclose known defects), and actively hid the fact (painted over evidence). If Buyer relied on the non-disclosure and suffered injury (cost of repairs or diminished value), HomeSeller is liable for fraud and the contract is voidable.
This is why many businesses adopt automated deadline tracking to ensure no critical dates are missed before they pass.

Representations Against Fraud and ConcealmentWatch Out For
Assuming silence about a fact is not fraud
In most cases, silence alone is not fraud. But if a duty to disclose exists (fiduciary relationship, direct inquiry, known defect in real estate), silence about a material fact is concealment and fraud. Know when you have a duty to disclose.Actively hiding facts and claiming passive silence
If you take active steps to hide a fact - falsify documents, destroy evidence, deliberately mislead - courts treat it as active concealment and fraud, even if you also remain silent. The active steps matter.Concealing facts you assume the other party will discover
Do not assume the other party will discover a material fact on their own. If you know a material fact and intentionally hide it, hoping they will discover it, that is still concealment and fraud. The other party's failure to investigate does not excuse your active hiding.Don't let concealment deadlines catch you off guard
Key dates tied to concealments - renewal windows, expiry cutoffs, notice periods - can easily slip through the cracks when tracked manually. Missing them triggers automatic extensions, penalties, or lost rights. ExpiryEdge tracks every critical deadline and sends automated reminders before they're due - so nothing slips.
Instead of relying on spreadsheets or manual follow-ups, a centralized renewal reminder system ensures every deadline is visible, tracked, and actioned automatically.
How to Use This in Your Favor
Disclose all known material facts in transactions
In sales of property, businesses, or significant assets, disclose all known defects, liabilities, and issues. Written disclosure is best. In many states, sellers have a legal duty to disclose; even where not required by law, disclosure prevents fraud claims and builds trust.Include explicit representations regarding disclosure
Include a clause: "Seller represents that it has disclosed all material facts known to Seller. Seller has not concealed or hidden any information." This creates a clear record and prevents later claims of hidden defects.In due diligence, actively inquire about material issues
As a buyer, do not rely on the seller's passive silence. Ask specific questions about known issues, defects, liabilities, and risks. A direct question creates a duty to disclose; silence in response is concealment.Related Terms
Frequently Asked Questions
Is silence always concealment?
No. Passive silence is generally not concealment unless a duty to disclose existed. Duties to disclose arise in fiduciary relationships, after direct inquiry, or (in many states) for known defects in real property. In ordinary commercial dealings without these special circumstances, silence is not fraud.
What is the difference between active and passive concealment?
Active concealment involves affirmative steps to hide a fact: falsifying documents, destroying evidence, or misleading. Passive concealment is remaining silent. Active concealment is fraud; passive concealment is fraud only if a duty to disclose existed.
Can I be liable for concealing a fact I did not know about?
No. Fraud requires knowledge of the concealed fact. If you genuinely did not know about a defect or problem, you cannot be liable for concealing it. However, you may be liable for negligent misrepresentation if you failed to make reasonable inquiry.
