Custodian
Also known as: Record Custodian, Records Custodian, Data Custodian
Simply put
A custodian is a person or organization responsible for protecting, caring for, or maintaining something entrusted to them. In records and information contexts, the term generally refers to whoever holds and safeguards records or information on behalf of others, though it does not by itself imply ownership of, or authority over, what is held.
Formal definition
In general usage, a custodian is one entrusted with guarding, keeping, protecting, or maintaining property or something of value on behalf of another party. The evidence packet supports this broad sense but does not establish a settled, records-management-specific technical definition; practitioners should note that in recordkeeping and e-discovery practice the term is commonly applied more narrowly to the party who physically or logically holds records or electronically stored information, as distinct from an owner, steward, or authority responsible for governance decisions. The precise scope of custodial duties, and whether custody carries responsibility for authenticity, integrity, and accessibility of records, typically depends on organizational policy, applicable jurisdiction, and the relevant legal or regulatory framework, none of which are specified in the evidence provided here.
Why it matters
The custodian role sits at the practical heart of records control because someone must actually hold and safeguard records and information, whether physically or logically, on behalf of the parties who own or govern them. Confusing custody with ownership or governance authority is a common and consequential error: the party who holds records is not necessarily the party entitled to decide their classification, retention, disposition, or release. Keeping these roles distinct helps organizations assign accountability clearly and avoid gaps where records are held but no one is responsible for their authenticity, integrity, or accessibility.
Who it's relevant to
Records managers
Records managers rely on clear custodial arrangements to know who holds particular records and who bears responsibility for safeguarding them across the lifecycle. Distinguishing the custodian who holds records from the owner or steward who governs them helps prevent gaps in accountability for retention and disposition.
Information governance officers
For information governance officers, the custodian role is one element in a broader accountability framework. Because custody does not by itself imply governance authority, these officers often need to define in policy how custodial duties relate to ownership, stewardship, and decision-making authority over records and information.
Compliance and legal teams
Compliance and legal professionals should note that the scope of custodial responsibility can vary by jurisdiction and by the applicable legal or regulatory framework. Because the precise duties attached to custody are not universally settled, these teams typically confirm what obligations custody carries in their specific context rather than assuming a single standard meaning.
Inside Custodian
Record Custodian
In records management, the party assigned responsibility for the physical or logical care, storage, and safekeeping of records over a defined period. Custody typically concerns control and preservation of the record, which may be distinct from ownership of the record or accountability for its content. The custodian is generally expected to maintain the integrity, security, and usability of records in their charge, though the precise scope of duties depends on organizational policy and applicable frameworks.
E-Discovery Custodian
In the context of legal discovery, particularly in United States civil litigation, a custodian is typically the individual (or sometimes system or department) who possesses or controls electronically stored information (ESI) that may be relevant to a matter and therefore subject to identification, preservation, collection, search, and production. This usage is reflected in practitioner resources such as the EDRM framework and Sedona Conference guidance. The applicability and terminology vary by jurisdiction and procedural regime.
Custody Versus Ownership
Custody denotes responsibility for holding and safeguarding records or ESI, whereas ownership or business accountability may rest with another party. A custodian may control records they did not create and for whose content they are not the authoritative source. Distinguishing these roles is important for allocating retention, disposition, and preservation obligations.
Custody and the Chain of Custody
Custodianship often connects to chain-of-custody considerations, where documenting who held or controlled a record or item of ESI, and when, supports claims about its authenticity and integrity. In many contexts this documentation is relevant to the evidential value of records, though specific requirements depend on jurisdiction and purpose.
Preservation Obligations
When a custodian's records or ESI fall within the scope of a legal hold, the custodian is typically expected to suspend routine disposition and preserve relevant material. The trigger, scope, and duration of such obligations depend on jurisdiction, sector, and the nature of the matter, and are often communicated through a hold notice.
Common questions
Answers to the questions practitioners most commonly ask about Custodian.
Does 'custodian' mean the same thing as the owner of a record?
No. In records management, a custodian typically holds and maintains records on behalf of another party, whereas ownership generally refers to the accountability for the record and decisions about its retention and disposition. Custody concerns physical or logical possession and care of the record, while ownership concerns rights and responsibilities over it. The two roles may reside with the same person or organization, but they are conceptually distinct and depending on organizational policy may be deliberately separated, for example, where a service provider holds records that another entity owns.
Is a custodian just someone who stores files, or does the role carry recordkeeping obligations?
The custodian role is more than passive storage. A record custodian is typically responsible for maintaining the authenticity, integrity, and usability of records in their care, and for ensuring appropriate access controls and handling throughout the period of custody. In an e-discovery context, the term also identifies the individual whose electronically stored information is subject to preservation, search, and production, which carries specific duties once a matter arises. Custody therefore commonly implies stewardship obligations rather than mere possession.
Who should be designated as custodian in a legal hold, and how is that decided?
In discovery, a custodian is generally the individual whose electronically stored information or records may be relevant to a matter and is therefore subject to preservation, search, and production. Identifying custodians typically involves assessing who created, received, or held potentially relevant information. The specific scope and process depend on jurisdiction, applicable procedural rules, and the nature of the matter, so custodian identification is usually undertaken in consultation with legal counsel.
How should the transfer of custody between parties be documented?
Transfers of custody are often documented to preserve a defensible record of who held the records and when, which supports the integrity and authenticity of those records. Documentation commonly captures the point of transfer, the parties involved, and the condition or scope of the records moved. The level of formality typically depends on organizational policy and, where records may be subject to legal or regulatory scrutiny, on evidentiary expectations in the relevant jurisdiction.
What obligations does a custodian have once a legal hold is issued?
Once a hold applies, a custodian is typically expected to preserve relevant records and refrain from altering or destroying them, and may be required to assist with search and production. These obligations generally suspend routine disposition for the affected records for the duration of the hold. The precise duties depend on the applicable procedural rules and the jurisdiction, and are commonly directed and overseen by legal counsel.
How does custodial responsibility relate to retention and disposition decisions?
Custodial responsibility concerns holding and maintaining records, while retention and disposition decisions generally rest with the record owner or the accountable function under a retention schedule. A custodian typically executes disposition actions, which may include transfer, permanent preservation, or destruction, in accordance with authorized instructions, rather than determining those actions independently. Where a legal hold is in force, custodians are expected to suspend disposition for the affected records until the hold is lifted.
Common misconceptions
A custodian owns the records or ESI they hold.
Custody generally concerns responsibility for the care, control, and safekeeping of records, not ownership or business accountability. A custodian frequently holds records they did not create and does not necessarily control decisions about their content, retention, or ultimate disposition, which may rest with an owner or governing authority.
Custodian has only a facilities or physical-storage meaning.
In records management and e-discovery, custodian is a defined role concerning responsibility for records or electronically stored information. In e-discovery in particular it typically refers to the individual whose ESI is subject to preservation, search, and production, rather than to physical building or equipment maintenance.
A custodian's routine disposition practices continue unchanged during litigation.
When a legal hold applies, a custodian is typically expected to suspend routine destruction and preserve potentially relevant records or ESI. The precise obligations depend on jurisdiction, sector, and the matter, but continuing normal disposition of material within scope can be inappropriate.
Best practices
Clearly document, in policy and in system configuration where applicable, which parties hold custody of specific records or ESI, and distinguish that role from ownership and business accountability.
Identify relevant custodians early when a legal hold or discovery obligation may arise, so that potentially relevant records and ESI can be preserved before routine disposition removes them.
Ensure custodians receive clear preservation instructions through documented hold notices, and confirm that they understand the need to suspend routine destruction for material within scope.
Maintain records of custody and, where relevant, chain-of-custody documentation to support later claims about the authenticity, integrity, and usability of records.
Align custodian responsibilities with retention and disposition schedules, recognizing that requirements vary by jurisdiction and sector and may change once a legal hold is in effect.
Periodically review custodian assignments as roles, systems, and organizational structures change, so that responsibility for records and ESI does not become orphaned or ambiguous.
