The American Bar Association has acknowledged that lawyers must take reasonable steps to safeguard client information when using technology, including generative AI tools. ABA Formal Opinion 477R emphasizes that attorneys should employ reasonable efforts to prevent inadvertent or unauthorized disclosure of client data. PII redaction before submitting documents to AI platforms represents one practical measure attorneys can adopt to mitigate the risk of exposing names, Social Security numbers, financial account details, and other sensitive identifiers. Tools like Justee automate this redaction process, scanning for over 30 entity types and replacing them with structured placeholders. By removing personally identifiable information prior to AI analysis, attorneys can obtain the efficiency benefits of generative AI while maintaining their duty of confidentiality. This approach aligns with the growing consensus among state bar ethics committees that proactive data protection measures are essential components of competent legal practice in the digital age.

What We Redact

Full names, aliases, and party identifiers replaced with [PERSON_1], [PERSON_2] placeholders

Social Security numbers, EINs, and tax IDs redacted to [SSN_1], [TAX_ID_1] format

Email addresses, phone numbers, and physical addresses anonymized systematically

Financial data including bank accounts, credit card numbers, and routing numbers removed

Case-specific identifiers such as docket numbers and bar IDs replaced with structured tokens

Risks of Sharing Unredacted Documents

Uploading unredacted client files to AI tools may constitute a breach of confidentiality duties

Exposed Social Security numbers and financial data create identity theft liability for the firm

AI platforms may retain or log submitted data, creating long-term exposure risks

Opposing counsel could use inadvertently disclosed information against your client

State bar disciplinary boards increasingly scrutinize attorney use of AI with client data

Hypothetical Case Study by Justee

A mid-size litigation firm wanted to use AI tools to summarize a batch of 40 employment contracts for a class action review. Each contract contained employee names, Social Security numbers, salary figures, home addresses, and direct deposit banking details.

Issue Found: A junior associate nearly uploaded unredacted contracts containing PII for 40 employees, which would have exposed sensitive personal and financial data to a third-party AI platform.

Resolution: The firm implemented a policy requiring all documents to be processed through Justee's PII redaction tool before any AI submission. The 40 contracts were redacted in under 8 minutes total, replacing all identifiable data with structured placeholders while preserving the contractual language needed for AI analysis.

Employment Contract Clause: Before vs. After Redaction

Why it matters: Every identifiable element is replaced with a typed placeholder, preserving the contractual structure for AI analysis while fully protecting employee PII. The AI can still analyze clause patterns, obligations, and terms without accessing any real personal data.

No credit card required

AI is transforming legal practice, but the duty of confidentiality does not pause for efficiency. Redacting PII before any AI interaction is not just best practice — it is the minimum standard of care attorneys should follow.
