1. The Search Warrant Sets the Limits of the Search
Federal Rule of Criminal Procedure 41 governs key aspects of a search warrant and its execution. The warrant identifies areas agents may search and property they may seize; a federal investigation does not authorize an unrestricted office search.
Check the Address, Rooms, and Record Categories
Read the warrant together with any attachments incorporated into it. Compare its locations, record categories, and date limits with the search conducted. Authorization to examine particular financial transactions does not necessarily extend to unrelated business activities.
For shared spaces, note which cabinets, workstations, and accounts agents accessed. A supporting affidavit may be sealed and does not automatically enlarge the warrant's scope. If an attachment is missing, document what agents presented rather than assuming it never existed.
Record Possible Scope Discrepancies without Interfering
Record eyewitness observations of areas searched and items removed, distinguishing direct knowledge from speculation. Note the approximate start and end times and retain unedited security footage, if available. Do not interfere with agents.
An apparent discrepancy does not itself invalidate a seizure. The Fourth Amendment, warrant wording, and exceptions such as plain view may affect the analysis. Counsel handling government and internal investigations can assess those issues against the documented sequence of events.
2. The Seizure Inventory Shows What Agents Took

The receipt and inventory document what agents took, while the warrant sets the authorized scope. Comparing them can expose unclear descriptions and missing equipment.
Match the Receipt against Company Records
Rule 41(f)(1) requires an officer executing an ordinary premises warrant to give or leave a warrant copy and a receipt for property taken. An officer must prepare and verify an inventory and return it with the warrant to the designated magistrate judge.
Compare the retained documents with asset registers, serial numbers, assigned users, and storage locations. If the inventory was not supplied, the person from whose premises property was taken may request a copy from the designated magistrate judge after its return under Rule 41(f)(1)(D). Avoid assuming that every searched folder contained seized records.
Distinguish Removed Devices from Copied Data
Rule 41(e)(2)(B) allows a warrant to authorize seizure of electronic storage media or copying of electronically stored information. Unless otherwise specified, it also permits later review consistent with the warrant. The execution period addresses seizure or on-site copying, not every subsequent forensic review. Later examination still must remain consistent with the warrant.
Rule 41(f)(1)(B) allows an inventory describing physical media without listing individual files. Distinguish seized laptops and drives from data copied on-site, and avoid assuming which files agents obtained.
Identify Records Needed for Continuing Operations
A seized server may disrupt payroll or reporting. Identify affected functions, available lawful copies, and records needed to resume operations. Do not present reconstructed files as originals. Inform counsel of filing deadlines or other operations affected by lost access.
Counsel may request access or return. Rule 41(g) permits an aggrieved person to seek the return of property in the district of seizure. The court evaluates the circumstances and may impose reasonable conditions on return. Broader issues of suppression and later charges belong to federal criminal defense.
3. Records Still Held by the Company Need Preservation
Agents may seize devices while relevant emails and backups remain with the company. Preservation should cover these sources and automatic deletion settings without altering original information.
Stop Relevant Automatic Deletion without Editing Content
Identify custodians, shared drives, messaging applications, and backup schedules. Suspend relevant deletion routines while retaining underlying records and metadata; document the steps taken. For personal accounts or devices, assess the company's lawful collection authority before accessing data.
Under 18 U.S.C. § 1519, knowingly altering or destroying records with intent to obstruct a federal matter, including one contemplated, may be criminal. Automatic deletion alone does not establish that intent. Deliberate interference raises related obstruction of justice questions.
Separate Legal Advice from Ordinary Business Materials
Confidential legal-advice communications may be privileged. Preexisting invoices and ledgers do not become privileged merely because they reach counsel. Disclosure to outsiders can also affect privilege. Attorney work product involves a related but distinct protection, with its own requirements.
Preserve such communications without unnecessary circulation. A federal criminal attorney can identify disputed materials and evaluate privilege review procedures. A "privileged" label alone is not decisive.
4. Employee Contacts Require Individual Decisions
Agents may contact employees during or after a search. The company should distinguish voluntary interviews from compulsory demands without directing witnesses toward a shared account.
Distinguish Interview Requests from Subpoenas
A voluntary interview request generally does not compel participation. Employees can ask whether they may leave and seek legal advice. A valid subpoena may require testimony or production, subject to objections and privilege.
Managers should not coach false accounts or conceal evidence. Under 18 U.S.C. § 1001, knowingly and willfully making materially false statements within federal jurisdiction can be a separate offense. Later demands may involve grand jury investigations, which follow different procedures from executing a search warrant.
Clarify Whom Corporate Counsel Represents
Corporate counsel ordinarily represents the company, not automatically its personnel. An executive's personal knowledge or conduct may create interests distinct from the organization's.
Before interviews, counsel should clarify whom they represent and assess conflicts. Employees should understand that the organization generally controls its privilege over corporate legal advice. Individuals may need separate counsel. A search does not establish guilt or mean a federal indictment will follow. The immediate priorities are the warrant, seized property, preserved records, and lawful responses to further requests.
