nanalLabs BlogSearch "lab notebook disposal" and most answers stop at one line: "once the retention period passes, a committee reviews it and disposes of it." In practice, once you actually sit down to clear out old notebooks, the real questions start right after that sentence — can you dispose of one before its retention period is up, whose sign-off do you need, what paperwork has to survive the disposal, and, above all, is now actually a safe time to do this. This post covers that second half. Institutional rules vary, so before disposing of anything, check both Korea's National R&D Research Note Guideline and your own institution's regulations.
There are only two grounds for disposal — and both require review
The guideline and institutional regulations recognize two grounds for disposal.
- **The retention period has passed, and the notebook is judged no
longer necessary to keep.** Passing "30 years" doesn't trigger automatic disposal — a judgment call is still required.
- **The retention period hasn't passed, but changes in the technical
landscape mean the notebook no longer has retention value.** For example, if the underlying invention has already been patented and published, the notebook may no longer serve a purpose as evidence of prior use.
In both cases, the decision can't be made by an individual researcher or department head alone — it has to go through review by an institutional committee. "The retention period was up, so we cleared it out" isn't, by itself, a procedural basis for disposal.
The disposal application and the disposal register — the paper trail you have to keep
Institutional regulations commonly require two documents.
| Document | Purpose | Common practice |
|---|---|---|
| Notebook copy/disclosure/removal/disposal application | Requests and secures approval for disposal (and copying, disclosure, or removal) | Many institutions print the form on the inside back cover of the notebook itself |
| Disposal register | Records when, what, and who approved the disposal | Kept separately by the managing department, alongside access logs and retrieval records |
The approver varies by institution — commonly the head of the technology-transfer office at a university, or the institution's head (or a delegated department head) at a government-funded research institute. If a physical notebook is shredded or a file deleted without either the application or the register, there's no way to later prove disposal followed procedure — without that trail, it's indistinguishable from "someone got rid of it on their own."
If litigation or a dispute is pending, don't dispose of it even if every procedural box is checked
This is the part most often missed. Even after the retention period has passed and a committee has signed off, disposal has to stop if the notebook is tied up as evidence in a prior-use-right patent dispute, the subject of a research misconduct investigation, or evidence in pending litigation.
Article 350 of Korea's Civil Procedure Act provides that if a party damages or disposes of a document it was obligated to produce, in order to prevent the opposing party from using it, the court may treat the opposing party's claims about that document's contents as true. In other words, even a procedurally clean disposal can backfire in litigation if its timing looks convenient — courts can treat it as intentional destruction. When a prior-use right is being contested, losing the original notebook does even more direct damage — we cover that in our post on prior use rights and proving trade secret originals. Before building a disposal list, it's safer to add a check — confirming the underlying project or technology has no connection to any dispute, investigation, or audit — as a formal step in reviewing the disposal application.
For an electronic lab notebook, "deleting" the file isn't the end of disposal
A paper notebook is physically done once it's shredded or incinerated. An electronic lab notebook isn't finished just because the original file is deleted. Without also checking automatic backups, cloud sync copies, and any copies left on an individual's device, the disposal decision and the data's actual existence can end up out of sync. Worse, if a copy turns up after the disposal decision, that fact alone can read as evidence of inconsistent management.
The disposal confirmation record should list each location cleared (original, backup, sync copy) item by item, and ideally log the time and the person who executed it — that's often the only evidence available later for explaining exactly when, what, and how far the deletion went.
Self-check for your institution
- [ ] Is it documented, in writing, which ground applied — "retention
period passed and no longer needed" or "no longer has retention value"?
- [ ] Did a committee actually review this, rather than an individual
making the call — and is there a meeting record or signature to show for it?
- [ ] Is the copy/disclosure/removal/disposal application actually being
filled out and kept on file?
- [ ] Does the disposal register record the date, method, and approver?
- [ ] Has anyone confirmed the underlying project or technology has no
connection to a patent dispute, misconduct investigation, or litigation/audit?
- [ ] For an electronic lab notebook, does the disposal scope cover
backups and sync copies, not just the original?
The last two items get skipped most often. Even with every procedural document in place, "is this actually a safe time to dispose of it" and "is it really gone everywhere" are separate questions that need separate answers.
