Does Your State Bar Require Metadata Scrubbing Before E-Filing?
At least 14 state bars have issued formal opinions on attorney metadata obligations. The malpractice exposure is real — and the consequences of sending metadata-laden documents to opposing counsel can be severe. Here's what the major jurisdictions require.
What Is Document Metadata?
Metadata is data embedded inside a document file that is not visible when the document is read normally. In legal documents, this typically includes: original author identity, revision history showing all tracked changes, dates and times of edits, document comments (including deleted ones), prior versions of text, printer information, and in some cases GPS coordinates if created on a mobile device.
When you send a Word document or PDF to opposing counsel, you may be sending all of this information along with it — even if the document appears clean on screen.
The ABA's Position
ABA Formal Opinion 06-442 (2006) addressed the sending of metadata: attorneys who receive documents with metadata are generally not prohibited from reviewing it, but the sending attorney has an obligation to take reasonable steps to prevent inadvertent disclosure of confidential information.
ABA Model Rules 1.1 (Competence) and 1.6 (Confidentiality) together create an affirmative duty to understand document metadata and prevent its accidental disclosure. ABA Formal Opinion 477R (2017) later reinforced that competence includes understanding the technology you use to create and send documents.
State-by-State Breakdown
The Malpractice Risk Is Real
Courts have consistently held that inadvertent disclosure of attorney work product via metadata can waive privilege in certain circumstances. While courts are split on whether the "inadvertent disclosure" doctrine protects attorneys who send metadata, the trend is toward stricter standards.
In In re Pacific Enterprises Securities Litigation, a firm lost privilege protection after an opponent extracted version history from a Word document. In the UK, the famous "dodgy dossier" scandal exposed intelligence source data via metadata — demonstrating that the problem extends well beyond American courts.
E-Filing and Court Submissions
Federal courts increasingly require PDF/A format for e-filed documents — which strips most metadata. However, many state courts still accept standard PDFs, and Word documents shared during discovery or informal production are never converted. Even with PDF/A, embedded font metadata and document information dictionary fields may still expose creation timestamps and software details.
Best practice: scrub every document before it leaves your control, regardless of format or destination.
