Digital litigation materials can exclude a participant long before anyone reaches the merits. A remote-hearing link that cannot be operated by keyboard, a deposition feed without intelligible audio, captions that omit a speaker change, an exhibit shown without verbal context, a scanned PDF that cannot be read by assistive technology, or a video player whose controls are inaccessible can each interrupt participation or review. The practical question is not whether a file exists. It is whether the intended user can obtain the information and operate the process on materially comparable terms.

For counsel, accessibility is both a planning discipline and a record discipline. The governing obligation depends on the forum, the entity conducting the proceeding, applicable court policy and orders, and the person’s requested accommodation. Identify needs early, preserve what occurred, and make documented choices about an effective process.

Start with the right legal and procedural frame

Title II: public entities and effective communication

Title II of the Americans with Disabilities Act applies to state and local government services, programs, and activities. Its effective-communication regulation requires a public entity to take appropriate steps to ensure that communications with applicants, participants, members of the public, and companions with disabilities are as effective as communications with others. The regulation calls for furnishing appropriate auxiliary aids and services where necessary. In determining the necessary aid or service, the public entity must give primary consideration to an individual’s requests. Effective aids and services must be provided in accessible formats, timely, and in a manner that protects privacy and independence. The separate fundamental-alteration and undue-financial-and-administrative-burden limitation is in 28 C.F.R. § 35.164; when that limitation applies, the entity must nevertheless take another action that, to the maximum extent possible, provides the benefits or services.

That is an entity-specific rule. If a state or local court, agency, board, or other public entity controls the proceeding or its digital materials, counsel should identify the entity’s accommodation channel promptly and coordinate rather than assume a vendor or opposing party can decide the accommodation. The Department of Justice’s effective communication guidance identifies qualified interpreters, notetakers, real-time captioning, written materials, and accessible electronic information as examples of auxiliary aids and services, while emphasizing context and the communication at issue.

Courts: follow the forum’s accommodation process

Courts publish their own procedures, and those procedures matter in addition to any broader legal analysis. For example, the U.S. Court of Federal Claims says its Access Coordinator coordinates sign-language interpreters and other appropriate auxiliary aids and services for participants in federal court proceedings, and asks participants to request services in advance. For the assigned tribunal, save the current accommodation procedure, use its named contact, and request written confirmation early enough for the court to act. Do not promise an accommodation on the court’s behalf.

For a deposition, mediation, arbitration, or private conference, the analysis may be driven by the governing rules, contract, venue, professional obligations, the host’s policies, and the facts of the request. Treat a request as concrete operational information: what communication or technology barrier is identified; at which event; who can make the decision; and what solution will be effective in that setting? Keep the substantive case theory separate from the logistics of access unless a court directs otherwise.

Section 508 and WCAG: related tools, not interchangeable labels

Section 508 concerns federal agencies’ information and communication technology. The U.S. Access Board explains that the Revised 508 Standards address access to information and communication technology under Section 508 of the Rehabilitation Act and incorporate WCAG 2.0 Level A and AA success criteria in specified web and electronic-content provisions. Applicability turns on Section 508, the standards, and any exception—not simply on whether a file is digital. That does not make every litigation file subject to Section 508, and WCAG is not a universal court rule. They are different sources with different scopes.

Still, WCAG is a precise and useful production vocabulary. W3C’s accessibility guidance explains the expected outcomes for captions, audio description, transcripts, keyboard operation, structure, contrast, and other common barriers. In a government matter, procurement or contract terms may expressly require a standard. In a private matter, accessibility criteria can be a prudent technical acceptance standard. Specify the standard and version, covered deliverables, testing method, and exception process—for example, tagged PDFs, caption files in a named format, and a keyboard-tested authenticated portal—rather than promising that materials will be “accessible.”

Issue-spot access during case planning

Accessibility planning begins at intake and is revisited when the event format, participants, exhibits, or delivery method changes. Ask the court or host what its process is; invite participants to identify an accommodation need through an appropriate, confidential channel; and avoid demanding medical detail that is unnecessary to arrange access. A request involving a deaf or hard-of-hearing participant may raise a different operational question from one involving a screen-reader user, a participant with low vision, or cognitive disability. Limited bandwidth and accessible parking may require separate logistics planning.

Make an event access plan alongside the usual witness, exhibit, and technology plan. Record the platform; dial-in alternative; host and technical contacts; captioning or interpreting arrangement if confirmed; document format; methods for describing visual material; and contingency steps. Consider who must have access: party, witness, attorney, juror where applicable, court staff, interpreter, expert, or member of the public. Distinguish information that must be accessible to participate live from materials that can be remediated for subsequent review.

Live participation is more than a video link

Test the actual route a participant will use. That includes account creation, authentication, waiting room, breakout room, chat, exhibit screen-sharing, raised-hand controls, audio input/output, and access to a telephone fallback. Confirm the platform’s keyboard behavior and whether its caption controls can be located and used without a mouse. If a screen share is essential, plan who will narrate the relevant visual content and how the witness or participant can receive the exhibit in a usable format. A platform’s general accessibility statement is not a substitute for an event-specific test.

Assign clear roles: one person conducts the proceeding; one manages exhibits; one watches the access channel and technical issues; and, when needed, one coordinates with the court or captioning/interpreting provider. Establish how a participant signals that communication has been missed, how a pause is requested, and how the record will reflect a material interruption. Avoid telling a participant to rely on auto-generated captions if the setting requires a different accommodation or the output is not effective for the person’s use.

Captions, CART, transcripts, and visual context

Select the product for the purpose

Captions are synchronized text for the audio in media. W3C’s explanation of WCAG 2.2 Success Criterion 1.2.2 says prerecorded synchronized media should have captions for audio content. A transcript is a text version of spoken content; it can support review, search, and access, but it does not by itself make a live proceeding accessible. CART—Communication Access Realtime Translation, also called computer-assisted real-time transcription—renders live speech as text. When arranging it, confirm the display route, retention, and whether it is effective for the requested accommodation. A qualified sign-language interpreter is a separate service.

For litigation production, label the deliverable accurately. A certified deposition transcript, a rough realtime feed, edited captions, and an automated transcript are not interchangeable. Preserve the source and status of each. If captions are created from a transcript, check synchronization against the final video and identify any editorial handling of inaudible passages, interruptions, nonverbal sounds, or speaker attribution. Do not silently “clean up” testimony in a way that obscures what the source record says.

Describe meaningful visual information

Where visual content communicates evidence or context, a blind or low-vision user may need more than the audio track. W3C describes audio description as synchronized spoken description of important visual content in prerecorded video; its WCAG 2.2 Success Criterion 1.2.5 addresses that outcome. In a live legal setting, counsel may instead need to state on the record what is displayed, identify an exhibit, read material portions, or provide an accessible equivalent. The right approach depends on the proceeding, accommodation plan, and evidentiary constraints.

Build description into the presentation plan. When showing a diagram, photograph, demonstrative, screen capture, or physical demonstration, identify the exhibit and verbally convey the features that matter to the question. Avoid a bare “as you can see.” The goal is not to narrate every pixel; it is to communicate the evidentiary proposition without forcing a participant to infer the visual premise.

Make documents and players usable

For newly created or derivative documents, a polished appearance does not ensure usability for someone navigating by headings, links, form fields, or reading order. Start from a structured source file where possible. Use real headings rather than enlarged bold text; lists rather than simulated bullets; meaningful link text; table headers; adequate color contrast; text alternatives for informative images; and a reading order that makes sense when linearized. Scanned PDFs require special attention: optical character recognition may create text, but it does not reliably create a correct reading order, heading structure, table markup, or useful image descriptions.

Exhibits create a practical tension. Original evidence may need to be preserved as received, including inaccessible or image-only material. Preserve the original; then, where appropriate and permitted, create a clearly identified accessible derivative or companion text description for access and review. Do not alter an evidentiary original under the label of remediation. Keep version relationships, hashes or other integrity information if your matter uses them, and any stipulated or court-approved procedure for providing the derivative.

For video delivery, assess the player as well as the media. Can a keyboard user reach play/pause, captions, volume, playback speed, and fullscreen controls? Are controls labeled for assistive technology? Does the player preserve captions when the file is downloaded or moved? Is the transcript reachable, searchable, and associated with the correct media? Test with the intended browser and authenticated delivery flow, not just a local desktop file.

Quality control, procurement, and delivery

Separate fidelity QC from access QC

Substantive QC asks whether the record is faithful: correct file, complete duration, intelligible audio, synchronized captions, accurate speaker labels, no missing material, and correct exhibit associations. Accessibility QC asks whether the user can operate and understand it: keyboard path, focus visibility, heading structure, reading order, alternative text, captions enabled and timed, transcript usability, and visual context. These are related but not identical checks. A legally significant omission can occur in either pass.

Automated checkers can flag some structural issues, but they cannot decide whether alt text communicates the relevant fact, whether captions identify the right speaker, whether an audio description is useful, or whether a workflow actually works with the portal’s authentication. Include manual review. For a consequential proceeding, conduct a dry run with the real platform, final-format media, and the person or role that will use the access path where feasible.

Questions for a vendor or platform

Preserve and deliver without losing access

Maintain the original capture and its associated metadata according to the applicable preservation plan. Preserve caption files, transcripts, accessible documents, and any audio-description track as distinct but linked deliverables; do not assume a hosted player will remain available forever. Document filename conventions, version, creation date, source, checksum or integrity method if used, and the relationship between an original and an accessible derivative. Restrict access consistently with protective orders, privacy obligations, and the sensitivity of the record.

Before delivery, test the recipient’s route: the invitation, permissions, expiration policy, download option, player controls, caption selection, transcript link, and alternate format. Repeat the event-path test after permissions or delivery settings change. An encrypted portal may be appropriate, but it still must be usable by authorized recipients. Preserve enough operational documentation to show what was delivered and when, while avoiding unnecessary collection of disability-related information.

Counsel checklist

1. Identify the forum, host, governing order or policy, and the correct accommodation contact.
2. Create a confidential route for requests and confirm the event-specific plan in writing.
3. Test the actual platform, dial-in fallback, authentication, exhibit sharing, and caption access before the proceeding.
4. Decide whether live captioning/CART, interpreting, accessible exhibits, verbal description, or another measure is needed; do not substitute formats without checking effectiveness.
5. Prepare witnesses and presenters to identify exhibits and describe material visual information on the record.
6. Preserve originals separately from accessible derivatives, and label the relationship between them.
7. QC both accuracy and usability: media, captions, transcript, document structure, player controls, and delivery portal.
8. Keep procurement representations, accommodation communications, testing notes, final files, and delivery confirmation in the matter record as appropriate.
