An incumbency certificate is an official corporate document that identifies the current officers, directors, and authorized signatories of a company and confirms each person's legal authority to act on the company's behalf. Banks, lenders, lawyers, and international counterparties request it to verify that whoever is signing a contract or opening an account is genuinely authorized to bind the company.
The corporate secretary typically prepares and signs the document. Unlike a Certificate of Good Standing, which is issued by a government agency to confirm regulatory compliance, an incumbency certificate is an internal document the company produces itself.
A complete incumbency certificate includes the legal name of the company, the names and titles of all current authorized officers and directors, the date of their appointment or election, specimen signatures for each listed person, and the corporate secretary's signature attesting to accuracy. Some versions include a company seal or notarization, particularly for international transactions.
Harvard Business Services notes that Delaware does not issue a state document confirming current ownership or management authority. That is precisely why incumbency certificates are so important: third parties dealing with Delaware entities have no other way to independently verify who holds authority to act.
These two documents serve entirely different functions. An incumbency certificate tells a third party who runs the company. A certificate of good standing tells them the company is in legal compliance with state filings, fees, and registered agent obligations.
Both are often requested together in major transactions, because a lender or acquirer wants to know both that the company is in good standing with the state and that the specific person sitting across the table actually has authority to sign.
Every time officers change, new directors are appointed, or signing authority is revised, the incumbency certificate needs to be updated. Presenting an outdated certificate can delay or void transactions. Insight Law in Ontario recommends reviewing the document before every major banking interaction or corporate transaction to confirm it accurately reflects current governance.
If a certificate is more than a year old, check whether any leadership changes have occurred before relying on it.
