Yes. There is a mature category of legal hold, eDiscovery, and records-management software designed specifically to replace spreadsheets, email chains, and manual tracking.
| System | Best suited for | What it streamlines |
|---|---|---|
| Relativity Legal Hold | Larger legal departments / litigation teams | Custodian identification, hold notices, acknowledgments, reminders, preservation, reporting |
| Legal Hold |

| Enterprise legal + compliance |
| Hold creation, custodian interviews, automated reminders/escalations, preservation and audit trails |
| Microsoft Purview eDiscovery & Records Management | Organizations heavily invested in Microsoft 365 | eDiscovery holds, preservation of Exchange/Teams/SharePoint/OneDrive data, retention policies and labels |
| Onna Preservation | Collaboration-heavy organizations | In-place preservation across Slack, Google Workspace, Microsoft 365 and other applications |
| Reveal Hold + Onna | Hold-to-collection workflow | Connects custodian hold issuance directly to data preservation and collection |
For example, Relativity's system can send hold notifications, interview custodians, automatically follow up with people who haven't responded, track responses, and generate an audit trail.
Exterro goes further into workflow automation, including configurable templates, automatic reminders and escalations, custodian interviews, preservation, and reporting.
That's slightly different from a legal hold.
A legal hold says, essentially: "Don't delete this information because there's a litigation/investigation reason to preserve it."
Records retention says: "Keep this category of information for X years, then dispose of it according to policy."
Microsoft Purview, for example, supports retention policies and retention labels for governing documents and email, while its eDiscovery functionality manages case-specific holds.
The more sophisticated platforms can connect these processes so the organization can answer questions such as:
If you're asking because you're considering building or improving such a system, there is definitely an established workflow to automate:
Matter opened → identify custodians → issue hold → acknowledgment → reminders/escalation → preserve data → monitor custodian changes → manage retention conflict → release hold → resume normal retention → maintain audit trail.
The biggest distinction between products is how deeply they actually automate preservation and retention, versus simply tracking that someone was sent a legal-hold email. For example, Microsoft Purview can place holds directly on Microsoft 365 data sources, while Onna and Relativity emphasize preservation across multiple enterprise data sources.
If you tell me whether you're looking at this from the perspective of (a) buying software, (b) building a system, or (c) researching the market, I can map out the leading vendors, features, pricing models, and gaps in the current solutions.
Yes, enterprise legal, compliance, and IT departments rely on specialized eDiscovery and Information Governance software to automate and streamline legal holds and document retention. These platforms replace error-prone manual tracking (like spreadsheets and individual reminder emails) with centralized, defensible workflows.[](https://www.gartner.com/reviews/market/legal-hold-software)
Key ways these systems streamline the process include:

The capability is typically a Records Management / Retention Policy Engine integrated with a Legal Hold/eDiscovery Engine. It calculates retention schedules and pauses disposition when a legal hold is triggered.
Examples include Microsoft Purview, OpenText, Exterro, Preservica, and Zasio.

An automated policy/records management engine (often part of an Enterprise Content Management (ECM), Electronic Records Management (ERM), or dedicated eDiscovery & Governance platform) is what dynamically generates and enforces retention schedules while maintaining integrated legal hold overrides.[](https://www.elo.com/en-us/blog/records-management-2026-retention-schedules-legal-holds-and-audit-ready-governance.html)[[2](https://www.doccord.com/records-retention)](https://www.doccord.com/records-retention)
Instead of static spreadsheets, these software engines tie metadata, event triggers (such as creation, contract termination, or project close), and hard-stop legal preservation rules directly to the data layer.[](https://www.elo.com/en-us/blog/records-management-2026-retention-schedules-legal-holds-and-audit-ready-governance.html)[[2](https://www.doccord.com/records-retention)]()
The "best" solution for litigation hold notices and custodian tracking depends heavily on your organization's size, IT infrastructure, and whether you need an isolated point solution or a fully integrated eDiscovery platform.[](https://www.veniosystems.com/guide/best-legal-hold-software-2026)

For litigation hold notices with custodian tracking, the best solution is usually a dedicated legal hold management platform rather than spreadsheets, email chains, or a general eDiscovery tool alone. The right choice depends on your scale, integrations, and whether you need preservation in place. Key capabilities to prioritize are automated notices, acknowledgment tracking, reminders/escalations, custodian questionnaires, audit trails, and reporting.
Here are the main options to evaluate:
| Solution | Best fit | Strengths |
|---|---|---|
| Mitratech LegalHold | Corporate legal teams needing streamlined hold administration | Custodian notices, acknowledgments, dashboards, audit trails, and integrations (including Microsoft 365-related workflows). |
Are you looking for an engine to integrate into an existing cloud stack (like Microsoft 365) , or do you need a stand-alone enterprise records management (ERM) solution for a specific regulatory environment?
| Exterro Legal Hold | Larger legal ops/eDiscovery programs | Strong workflow automation, custodian tracking, escalation, and reporting. |
| Relativity Legal Hold | Organizations already using Relativity for eDiscovery | Keeps legal hold workflows connected with broader discovery processes. |
| OpenText Core Legal Hold | Enterprises needing centralized preservation workflows | Automated notices, acknowledgment tracking, custodian management, and defensible audit records. |
| Everlaw Legal Holds | Teams wanting hold + discovery in one environment | Combines legal hold workflows with eDiscovery review capabilities. |

If you are currently using Microsoft 365/Teams, Relativity, ServiceNow, or a matter management system, that integration choice may matter more than the standalone hold features. I can help narrow it down if you share your environment (company size, number of custodians per hold, and current eDiscovery stack).
