Certified E-Discovery Specialist (CEDS) key terms

A written directive telling custodians to preserve documents and data relevant to anticipated or active litigation, suspending routine deletion until the matter concludes. It is typically issued once a duty to preserve arises.

The obligation to refrain from destroying potentially relevant information once litigation is reasonably anticipated or filed. It arises from case law and procedural rules and triggers issuance of a litigation hold.

The point at which a party knows or should know that a dispute is likely to lead to legal action, triggering preservation duties. Courts assess it objectively based on the facts known at the time.

A person who created, received, or holds information potentially relevant to a matter, such as an employee with knowledge of the facts. Custodians are the primary targets for preservation and collection.

An inventory describing what information systems an organization uses, where data resides, who owns it, and how long it is retained. It guides preservation, collection, and proportionality decisions during planning.

The policies and practices an organization uses to manage information throughout its lifecycle, covering retention, security, and defensible disposal. Strong governance reduces discovery risk and cost.

A documented plan specifying how long each category of records must be kept and when it may be destroyed. It supports defensible deletion and must be suspended for data subject to a litigation hold.

Deleting information under a documented, consistently applied policy before any preservation duty arises, with a record showing the deletion was routine and reasonable. It protects against later spoliation claims.

A preliminary review of data volume, key custodians, and likely issues performed early in a matter to estimate scope, cost, and risk. Findings inform planning, budgeting, and settlement strategy.

The principle that discovery scope and effort should be balanced against the importance of the issues, the amount in controversy, and the burden and cost involved. It justifies limiting or phasing collection and review.

The process of gathering identified electronically stored information from custodians and systems in a forensically sound manner, preserving metadata and chain of custody. It follows preservation and precedes processing and review.

A documented record tracking who handled evidence, when, and how, from collection through production. It demonstrates that data was not altered and supports admissibility.

A unique digital fingerprint computed from a file's contents, used to verify that data has not changed. Matching hashes before and after transfer help prove integrity and support de-duplication.

Preparing collected data for review by extracting text, applying date filters, removing system files, and de-duplicating. It reduces volume and organizes documents into a searchable review platform.

Identifying and removing exact or near-identical copies of documents so each unique item is reviewed once. It lowers review cost and can be done globally across custodians or within a single custodian.

Using machine learning or algorithmic ranking to identify relevant documents for review, often with a human quality-control sample. It can reduce review cost when its reliability is validated and documented.

A statistically drawn subset of documents checked by a human reviewer to measure the accuracy of an automated or manual review process. Results are used to validate and tune the workflow.

A contractual arrangement allowing a producing party to retrieve documents inadvertently produced despite privilege claims, often paired with a court order under evidence rules. It reduces the risk of privilege waiver.

A document-by-document list of materials withheld from production on privilege grounds, typically showing author, recipient, date, and basis. Courts may excuse or require it depending on the governing rules.

The accidental disclosure of privileged or otherwise protected material during discovery. Producing parties often seek its return, and receiving parties may have an ethical duty to notify the sender.

A rule protecting confidential communications between a lawyer and client made to obtain legal advice from compelled disclosure. It can be waived by voluntary disclosure to third parties.

Protection for materials prepared by or for a party in anticipation of litigation, shielding the attorney's strategy and mental impressions. It is narrower than privilege and can be overcome by substantial need.

The loss, destruction, or alteration of evidence that a party had a duty to preserve. It may result in sanctions, adverse inferences, or independent tort liability depending on the jurisdiction.

The challenge of applying preservation duties when data sits in multiple countries whose laws may conflict with U.S. discovery obligations. Planners must reconcile blocking statutes, privacy laws, and local procedure.

A multinational treaty, including the Hague Evidence Convention, that provides procedures for taking evidence abroad through central authorities. It offers a channel for cross-border discovery where direct requests are contested.

A formal request from a court in one country to a court in another, asking it to compel testimony or evidence from a witness abroad. It is typically slow and processed through diplomatic or judicial channels.

A national law that prohibits or penalizes compliance with foreign discovery requests, such as certain European data protection measures. It creates conflicts for parties ordered to produce data located abroad.

Legislation regulating the collection, transfer, and processing of personal data, such as the GDPR. It can restrict cross-border transfers and require safeguards before data is sent for review or production.

Moving data from one jurisdiction to another, which may require a lawful transfer mechanism such as consent, standard contractual clauses, or an adequacy finding. It affects where review and hosting can occur.

The principle that each state controls activities within its territory, including data stored there. It underlies resistance to foreign discovery orders and shapes how multinational collection is planned.

The deference courts show to foreign laws and interests when resolving conflicts between domestic discovery demands and another country's restrictions. Courts often balance competing sovereign interests case by case.

A situation where complying with one jurisdiction's discovery order would violate another jurisdiction's law, such as a privacy or secrecy statute. Planners must identify conflicts early and seek court guidance.

The ethical duty of a lawyer to possess the legal and technical knowledge reasonably necessary for a matter, including familiarity with e-discovery tools and processes. Lacking it may require education or association with an expert.

The lawyer's responsibility to reasonably oversee e-discovery vendors and subordinate staff performing collection, processing, or review. Outsourcing tasks does not outsource the ethical duty to manage them.

The ethical obligation to protect client information from unauthorized disclosure, which extends to data shared with vendors and during cross-border transfers. It requires safeguards such as encryption and access controls.

The duty to be truthful and forthcoming with the court, including correcting false statements and disclosing adverse legal authority. In e-discovery it can require disclosing preservation or production failures.

Penalties a court imposes for discovery misconduct such as failing to preserve, producing incomplete data, or violating orders. They range from cost-shifting to adverse inferences and default judgment.

The ethical and practical expectation that parties work together on discovery scope, formats, and search methods to reduce disputes. It is encouraged by procedural rules and case law on proportional discovery.

A court-issued directive requiring a party to maintain specified evidence pending resolution of a matter. It supplements a party's own litigation hold and may specify scope and reporting requirements.
