The black box that isn't really a box.
NRCP 5.2 requires you to redact certain identifiers before you file. The problem most firms don't catch until it matters: a black rectangle drawn on top of a PDF is not a redaction. A reader can still copy the text sitting underneath it. Nevada's obligation is real, the liability is real, and a PDF annotation tool is not the right answer. Here is how to do it right, preserve your original, and keep every decision with your staff.

What Nevada actually requires before you file
NRCP 5.2 sets the baseline for personal-data redaction in Nevada civil proceedings. Before a document is filed electronically, the filer must limit the personal information that appears on the public record. The rule covers Social Security numbers and Tax Identification Numbers (only the last four digits may appear), financial account numbers (only the last four digits), minors' names (only initials), dates of birth (only the year), and home addresses in criminal cases (only the city and state). This is not a courtesy; it is an obligation, and it runs to whoever files the document.
The Eighth Judicial District Court's Electronic Filing and Conversion Rules (EDCR) incorporate these requirements into the e-filing workflow. Clark County's local rules amplify them in certain contexts. Statewide, Nevada RPC 1.6 ties confidentiality obligations to how you handle client information in filings. None of those rules treat a black rectangle painted on top of a text-searchable PDF as sufficient.
Where full sealing of a document (or portions of a record) is appropriate rather than redaction of specific fields, SRCR 10 and the local sealing rules set out the procedure for moving to seal. Redaction and sealing are different tools for different situations. This guide covers the redaction obligation; sealing motions involve their own procedural requirements and are a matter for the attorney's judgment on a case-by-case basis.
Confirm the current text of NRCP 5.2, EDCR, SRCR, and your department's local rules before relying on any requirement stated here. Rules are amended, and this guide reflects a point-in-time summary.
The classic failure: the box that is still readable
Here is how the most common redaction error happens. A paralegal opens the PDF in a viewer, draws a black rectangle over the Social Security number, saves the file, and calls it redacted. The visual looks clean. But inside that PDF, the text layer is untouched. Anyone who opens the file, clicks on the black box, and presses Ctrl-A or Ctrl-C gets the number. The NSA does not need to be involved. Any court clerk, opposing counsel, or journalist can do it in ten seconds with any PDF reader.
This has caused real harm in filed documents, not theoretical harm. Courts have sanctioned parties for redaction failures. Clients' Social Security numbers, minors' identifying information, and financial account details have appeared on public dockets because someone drew a box on a PDF and thought the job was done. The mistake is structurally invisible in a normal document review: the file looks right on screen, the page looks right in print, and the exposure lives in the metadata layer that no one looks at.
The correct fix is to remove the underlying text, not to paint over it. That requires either rasterizing the page (converting it to an image so there is no text layer to expose) or using a tool that genuinely strips the character data from the area being redacted. Burning the redaction into the raster is the safest approach because it eliminates the text layer entirely at the redacted region. There is no text to recover because there is no text there.
Why the original has to survive
The redacted version is what goes to the court, to opposing counsel, and onto the public docket. The unredacted original is what you keep. This is not optional.
The original may be needed under seal if the court requires it. It is the controlling document for litigation: if a dispute arises about what the redacted field actually said, you need the original to resolve it. It is the version your client authenticated when they signed or produced it. Destroying or overwriting it in place creates a records gap that can look, at best, careless and, at worst, like spoliation.
Many firms find out the hard way that their redaction workflow replaced the original. A tool that opens the file, burns in a redaction, and saves to the same path has destroyed the original. A workflow that produces a separate redacted copy, named distinctly, while the original sits untouched in the matter folder, is the defensible one.
How DilloLex handles redaction
DilloLex is an appliance that sits on hardware your firm owns. No client content goes to an outside AI. The redaction workflow runs entirely on the appliance, on your network, under your control.
Here is how it works in practice:
- Detection. When a document enters the matter folder, the appliance scans it and flags likely PII and PHI: Social Security numbers, financial account numbers, dates of birth, minors' names, and home addresses. The flagging is pattern-based and context-aware, but it is not infallible. Detections are presented as a queue, not as final redactions.
- Staff review. A member of your staff reviews the flagged items before anything is redacted. Each flag shows the detected value in context, so the reviewer can confirm it should be removed, mark it as a false positive, or add items the detector missed. Nothing is redacted without a human authorizing it.
- Attorney approval. The supervising attorney reviews and approves the redaction set before production. The judgment about what to redact, and whether the result is complete and accurate, stays with the attorney throughout.
- Raster burn. Once approved, the appliance produces a separate redacted copy with the approved regions converted to raster. The black boxes in the output are image pixels. There is no text layer underneath them. A reader cannot copy, select, or recover the redacted content.
- Original preserved. The original document is not touched. It remains in the matter file, unaltered, as the record of what was there before redaction.
The result is two files: the redacted copy, suitable for filing or production, and the unredacted original, preserved for the matter record. The appliance logs what was redacted, by whom, and when, so the decision trail exists if it is ever needed.
A candid word on what no tool can promise
No automated tool, including DilloLex, can guarantee that it catches every identifier that should be redacted. Pattern detection works well on clearly formatted fields like SSNs and account numbers; it works less reliably on freeform text where a minor's full name appears buried in a narrative sentence, or on poor-quality scans where OCR may misread a digit. The detection step is a first pass that is meant to reduce the manual burden and surface the obvious items, not to replace careful human review.
This is a P0 product principle, not a disclaimer buried in the fine print: the attorney remains responsible for verifying that the redacted version is complete before it is filed. DilloLex assists the firm's staff. The supervising attorney makes the call. That division of responsibility is built into the workflow by design, and the human approval gate exists because no software should be the last line of defense on a confidentiality obligation.
The workflow in a typical Nevada civil matter
Consider a Las Vegas PI firm preparing a demand package that includes medical records and billing statements for a client named Jane Roe. The records contain the client's date of birth, Social Security number, and full home address. The billing statements contain the provider's NPI and partial account numbers.
Without a systematic process, a paralegal reads through each document, manually marking what to redact, then applies boxes in Acrobat, then saves. If the save overwrites the original, the unredacted version is gone. If the boxes are annotation layers, the text underneath is still there.
With the DilloLex workflow, the paralegal drops the records into the matter folder. The appliance flags the SSN, the date of birth, and the address across the relevant pages. The paralegal reviews the queue and confirms each flag, adds the one the detector missed in a handwritten note on page 14, and sends the set for attorney review. The attorney approves. The appliance burns the approved redactions into a raster copy. The original records remain in the matter folder. The redacted set goes out. The log records who approved what and when.
The same process applies to any filing that goes to the court: exhibits to a motion, financial documents behind an NRCP 16.2 disclosure, records attached to a petition. The workflow does not change based on document type, and the Bates numbering that follows runs on the redacted copy, not the original, which is the correct sequence. See the Bates numbering guide for how DilloLex handles that step.
Sealing vs. redaction: the short version
Redaction removes specific fields from a document that is otherwise publicly filed. Sealing removes the entire document from the public record. They are not interchangeable, and choosing between them is a legal judgment, not a software function.
Nevada SRCR 10 sets out the requirements for sealing court records, including the procedural steps and the findings a court must make. If the sensitive information is so interwoven with the substance of the document that targeted redaction would render it meaningless, or if the applicable rule requires the document to be filed under seal rather than redacted, the sealing route may be appropriate. That decision belongs to the attorney.
DilloLex supports the redaction side of this. It does not file documents, does not make sealing decisions, and does not determine what the court will require. Those are legal judgments.
Common questions
What identifiers must be redacted before filing a Nevada civil court document?
Under NRCP 5.2, filers must limit Social Security and Tax Identification Numbers to the last four digits, financial account numbers to the last four digits, minors' names to initials, dates of birth to the year only, and home addresses in criminal cases to city and state only. This is a general summary; confirm the current rule text and your court's local rules before relying on it.
Is a black box drawn on a PDF an adequate redaction under Nevada rules?
No, if the black box is an annotation layer on top of a text-searchable PDF. The underlying text remains in the document and can be copied or extracted. An adequate redaction removes or destroys the underlying data, typically by burning the redaction into the raster of the page so there is no recoverable text at that location.
Do I have to keep the unredacted original after filing the redacted version?
Generally yes. The unredacted original may be required by the court under seal in certain circumstances, and it is the controlling record for your matter. Destroying or overwriting it creates a records gap and potential spoliation exposure. The redacted copy goes to the court; the original stays in the matter file.
When should I move to seal a document rather than just redacting it?
Sealing is appropriate when the entire document, or a substantial portion of it, must be withheld from the public record, typically because the sensitive content cannot be isolated to specific fields. Nevada SRCR 10 sets out the procedural requirements. The choice between redaction and sealing is a legal judgment for the supervising attorney; it is not a software decision.
Can DilloLex guarantee it will catch every identifier that should be redacted?
No. Pattern detection reliably surfaces common formatted fields such as SSNs and account numbers, but it may miss identifiers embedded in narrative text, poor-quality scans, or unusual formats. The detection step reduces the manual burden; it does not replace attorney review. The supervising attorney is responsible for verifying the redacted version is complete before filing.
