EDNY Legal Holds, Collections and Productions
Brooklyn and Central Islip Discovery, Preserved Before the Order
An Eastern District case turns on what was preserved before the scheduling order arrived and on whether the production loads cleanly on the other side. Global Digital Forensics holds the tenants, images devices at custodian sites from Brooklyn to Suffolk and processes everything on software we own. The examiner who made each collection choice can defend it before the assigned judge.
The engagement
First Week Decisions That Decide the Production
Reach the New York office at (212) 561-5860 or the 24/7 hotline at (800) 868-8189 the day a hold issues. The Eastern District of New York covers Brooklyn, Queens, Staten Island, Nassau and Suffolk, and the assigned judge's scheduling order sets the discovery calendar. The decisions made in the first days, which custodians to hold, which tenants to preserve and which production form to propose, decide which records still exist when the production is due and whether the receiving team can work with them. We help counsel make those decisions with a clear view of what the systems can actually produce.
On the technical side GDF supports an EDNY matter from preservation on notice through defensible collection at the source, processing that respects the production form obligations of Rule 34, review platform loading and production in the form the receiving party accepts, with expert testimony on the technical record where the engagement includes it. Collections are performed on site at Brooklyn, Queens, Nassau and Suffolk custodian locations when the source requires it and remotely when it does not.
The engagement is scoped against the assigned judge's individual practices and the Rule 26(f) conference, and where the case management order calls for an ESI protocol we negotiate the technical detail, meaning source coverage, collection tools, processing conventions and production form, so the protocol describes what will actually happen. Our eDiscovery collections and production pages explain the national practice behind this work.

Scope
Legal holds and preservation
Written hold notices, custodian interviews and preservation in place or targeted preservation collection, chosen source by source. For custodians spread across Brooklyn, Queens and Long Island, preservation is coordinated centrally so the record shows one clean timeline of what was held and when.
On site collections across the district
Forensic imaging with write blockers at custodian locations in Brooklyn, Queens, Nassau and Suffolk, with chain of custody documentation completed on site. The examiner records condition, acquisition coverage, tool version and integrity verification before leaving the premises.
Cloud and SaaS collections
Mailboxes, chat, files and administrative logs collected through first party tools such as Microsoft Purview eDiscovery and Google Vault where they are licensed and supported, and through tested connectors where they are not. Retention policy interactions are documented so the record shows what could and could not be preserved.
Processing and review platform loading
Deduplication, near duplicate suppression, email threading and technology assisted review workflows on GDF's own processing platform, loaded to the review environment the legal team selects or hosted by GDF. Structured data from financial, ERP, warehouse and driver logging systems is normalized so it can sit beside the unstructured record.
Production
Load files built to the receiving party's specification, native production where the record requires it, slip sheets for withheld and redacted documents and a manifest that ties every produced item back to its source.
Expert testimony
Where the collection or production method is challenged, GDF supplies the technical record and, where retained for it, expert testimony before the assigned judge in Brooklyn or Central Islip. Our examiners are court tested and the Southern District of New York found our founder's testimony highly credible in COMLAB v. Kal Tire.
Evidence commonly reviewed
The Paper Trail Behind Each Collection
The technical record in an EDNY matter is built from chain of custody records for every on site collection, collection logs recording the tool, its version, the target and the hash for every device or tenant, processing manifests with deduplication and near duplicate counts, load file specifications and production manifests, and the preservation and retention hold audit trails exported from each cloud tenant. Each of those documents is kept because each is what an opposing party asks for when the production is challenged.
What you receive
Deliverables From Notice to Production
Counsel receives preservation notice templates aligned to Rule 26(f) practice, on site collection reports written so they can serve as exhibits, processed data loaded to the review platform of record, production sets in the form the receiving party accepts and, where the matter reaches it, an expert report on the collection or production method prepared by the examiner who performed the work.

How We Run Discovery Across the District
Preservation across Brooklyn, Queens and Long Island custodians
EDNY matters commonly involve custodians in several counties. Preservation is coordinated from the New York intake with a single notice written for the matter, and tenant side holds in Microsoft Purview, Google Vault, Slack and Zoom are placed for the relevant custodians and time windows. Where a Nassau or Suffolk custodian runs a small business set of SaaS accounts, preservation extends to the specific accounts that carry the record rather than to a blanket tenant wide hold.
On site collections in Brooklyn, Queens and Long Island
When a collection has to happen in person, we confirm the address, the authorized receiver, the appointment, the supported method and the operating window first. The handling record identifies condition, acquisition coverage, tool version, known changes and integrity checks appropriate to the output, with photographs where useful, and travel, acquisition and analytical review are tracked as separate tasks with confirmed milestones.
Processing under the governing order
Processing follows the same defensible pipeline used across the practice: file identification, text and metadata extraction, deduplication, near duplicate analysis, threading, language identification and exception logging. Where the assigned judge has entered an ESI protocol, processing conventions are aligned to it before ingestion begins, and where the protocol is silent, standard EDRM conventions are followed and documented.
Review hosting and access controls
Review is hosted on the platform of the firm's choosing or in GDF's own hosted environment. Reviewer accounts are provisioned for the specific engagement only, multifactor authentication is enforced and workspace access reports are produced on a cadence, so there is a record of who accessed what and when. Where a protective order limits access to attorneys' eyes only, the platform's access controls implement that order.
Production and post production support
Productions are prepared in the form the receiving party accepts, whether image with load file, native with load file or hybrid, with Bates numbering, confidentiality endorsements, redactions and privilege logs prepared to the specification the attorneys set. A supplemental production carries a manifest that ties back to the original so the record stays easy to follow.
If the hold notices have not gone out yet, start with the legal hold service so the production has a clean preservation record behind it.
Frequently asked
Describe the sources and the production format, and a senior specialist will map the collection.
Brooklyn, Central Islip, Rule 45 and Rule 37
Can you cover Brooklyn and Central Islip in the same matter?
Yes. Matters that touch both courthouses are common. Preservation and collection are coordinated from the New York intake, and on site collections are performed at Brooklyn, Queens, Nassau and Suffolk custodian addresses as the sources require.
How do you handle an EDNY matter with a compressed schedule?
Where the case management order sets a compressed discovery schedule, preservation and collection are prioritized against the specific milestones in that order. We write the processing and review load timeline back to the case team so the schedule is realistic against the volume, and we raise any gap in the first week, while there is still time to negotiate.
Can you handle Rule 45 nonparty subpoenaed collections?
Yes. Nonparty collections are handled with particular care to scope, so the nonparty is not asked to produce beyond what the subpoena actually requires. Collection is coordinated with the nonparty's counsel and documented to the same standard as a party collection.
Do you handle logistics industry ESI near JFK?
Yes. Cargo, freight forwarder and third party logistics matters commonly involve warehouse management systems, transportation management systems, driver electronic logging devices and camera systems. Preservation is scoped to the specific systems and time windows that cover the disputed event.
Can you defend the production form at a Rule 37 hearing?
Yes. Where the production form is challenged, GDF provides the technical record for the production choice and, where retained for it, expert testimony before the assigned judge. The examiner who made the choice is the one who explains it.
Plan EDNY Collection From the Actual Order
Work from the assigned Brooklyn or Central Islip order, the custodians' availability and the receiving party's requirements. Confirm the source location, the administrator's authority, the retention settings and the collection window, then separate exact duplicates, near duplicate review and email threading while retaining the mapping from source to delivery and every exception along the way.
A delivery row in our manifest shows a parent email, its attachment, the requested fields, the delivered native and any failed item still pending resolution. We test a small authorized handoff with the receiving platform before the full production, while counsel makes the responsiveness, privilege and production calls.
When custodians or receiving reviewers are split between locations, agree on the encrypted transfer route, the acceptance owner and the exception queue in advance. Retain each custodian's association after deduplication and resolve failed natives or attachments before marking a delivery complete.
