What happens if I forget or get the attribution wrong?

Forget the attribution and your Creative Commons 4.0 license terminates automatically. No warning. No polite email from the creator. The moment you breach the attribution condition, you lose permission to use the work. You are now infringing copyright. The 4.0 legal code gives one decisive exception: a 30-day cure period from the date you spot the violation. Fix the attribution within those 30 days and your license is automatically reinstated from the date of cure. This does not erase liability for the period you were out of compliance. It stops the ongoing violation. The moment you notice a missing or incorrect attribution, correct it and timestamp the correction. Do not wait. Do not assume a message to the creator will suffice. The 30-day clock starts when you spot the problem, not when the rights holder notifies you. If you never spot it, the license remains terminated from the moment of the original breach.

Under Creative Commons 4.0, the attribution condition requires you to retain any attribution information supplied by the rights holder. That includes the creator's name, a copyright notice, a notice referring to the license, a warranty disclaimer if supplied, and a URI or hyperlink to the material where reasonably practicable. You must also link or refer to the license and indicate any modifications you made, preserving earlier modification notices. Version 4.0 does not separately require the work's title, although including it is useful practice. Older versions may require it when supplied. If the rights holder requests it, you must remove attribution information where reasonably practicable. Attribution must not imply endorsement. Failing to include any of these elements, or getting them wrong, breaches the condition. The breach is automatic. There is no grace period built into the condition itself. The only grace period is the cure period after you spot the error.

Version 4.0 terminates automatically on breach. You do not receive a warning from Creative Commons; it is not a party to the license and does not monitor compliance. The termination happens the moment you use the work without complying with the conditions. From that point, you are an infringer. The rights holder can pursue legal remedies under applicable law.

What the Cure Period Does

The cure period does not prevent the breach from happening. It provides a path back into compliance. If you cure within 30 days of spotting the violation, the license is automatically reinstated from the cure date. You can lawfully continue using the work going forward. The period between the breach and the cure remains a period of unauthorised use.

Older Licenses Work Differently

Older license versions do not contain this automatic 30-day mechanism. If you are using a 3.0 or earlier license, the cure period may not apply at all. Check the exact version and legal code of the license you are using.

The 30-day cure period is a specific provision in the 4.0 legal code. It applies only when you spot the violation. Spot it today and correct it within 30 days, and your license is automatically reinstated from the date of correction. The cure period does not apply if the rights holder notifies you of the breach and you ignore it. The clock starts when you spot it, not when they tell you. If the rights holder demands a correction and you comply within 30 days of your own discovery, you are covered.

If You Never Notice the Breach

If you never spot the breach, the license remains terminated. There is no obligation on the rights holder to notify you. The cure period is an opportunity, not a safety net. Document your discovery date and the correction date with a screenshot or timestamped log. This protects you if a dispute arises later.

Breach Type	Effect on License	Cure Period Applies?
Missing attribution entirely	Automatic termination from first use	Yes, if spotted by reuser
Incorrect attribution (wrong name, wrong license)	Automatic termination from first use	Yes, if spotted by reuser
Missing modification notice	Automatic termination from first use	Yes, if spotted by reuser
Removed attribution after rights holder requested retention	Automatic termination from first use	Yes, if spotted by reuser
Breach under 3.0 or earlier license	Automatic termination, no cure period	No

Correcting an attribution requires you to re-evaluate the original source. Do not rely on a repost, search thumbnail, or platform filter alone. Open the original source page and record the creator, source URL, exact license and version, displayed notices, exclusions, and the date checked. Preserve a screenshot when the use matters.

What To Include in the Correction

Update your use to include all required elements: creator name, copyright notice, license reference, warranty disclaimer if supplied, and a URI or hyperlink to the material where reasonably practicable. Add an indication of changes you made if you modified the work. Remove any false endorsement. The attribution must be in a reasonable manner for the medium. A consolidated credits page can work if the mapping from work to credit is clear and remains readily accessible. Academic citation and license attribution serve different purposes; do both when both apply.

The TASL mnemonic, title, author, source, license, is a useful attribution reminder. It is not the complete legal text of the 4.0 attribution clause. Version 4.0 does not separately require the work's title. Including it is good practice. Older versions may require the title when supplied. Adding a modification notice is required under 4.0, not optional. Preserving earlier modification notices is also required. If the rights holder supplied a copyright notice, warranty disclaimer, or a notice referring to the license, you must retain them. TASL is a shortcut. The legal code is the authority. Do not treat TASL as sufficient. Use it as a checklist, then verify against the exact license deed and legal code.

When you modify a Creative Commons-licensed work under terms that permit adaptations, you must indicate that you made changes. This is not optional under 4.0. The indication must be clear enough that a downstream user knows the work has been altered. You do not need to describe every change. You must say that modifications were made. Preserve any modification notices left by previous adapters. If you create a derivative work, your adaptation must carry its own license notice, and the attribution for the original must remain. Failure to mark changes is a breach of the license condition, triggering the same automatic termination and 30-day cure period.

If you spot that you have used a Creative Commons-licensed work without proper attribution, or with incorrect attribution, act immediately. Correct the attribution on your site, publication, or platform. Add the missing elements: creator name, copyright notice, license reference, URI or hyperlink to the material where reasonably practicable, and an indication of modifications.

Document Everything

Record the date and time you spotted the error and the date and time you completed the correction. Do this even if the rights holder has not contacted you. The 30-day cure period runs from your discovery, not from their notification. A proactive correction within 30 days of your own discovery reinstates your license automatically.

After the 30 Days

A corrective action taken after 30 days from your discovery does not have the same automatic effect. It requires express reinstatement by the rights holder. That is a slower, less certain process.

A common failure is not spotting the error yourself. A reuser posts a work, forgets to include the creator name, and never revisits the page. Years later, the rights holder finds it. Because the reuser never spotted the error, the 30-day cure period never started. The license terminated on the date of the first unauthorised use and has remained terminated. The rights holder can demand removal or compensation for the entire period.

Relying on Shortcuts

Another common failure is relying on TASL alone and omitting required elements from the 4.0 legal code, such as the copyright notice, warranty disclaimer, or modification indication. A third failure is treating a correction after 30 days from discovery as automatically effective. It is not. It requires express reinstatement by the rights holder.

Build a Process

The single piece of practical advice: build a process that forces you to record the creator, source URL, exact license and version, and modification status before you publish. That process, not memory, is what prevents the breach in the first place.
