Legal CRM for Antitrust and Competition Lawyers

A merger review is never actually one matter. It is a US HSR filing, a UK CMA notification, an EU Commission filing, and sometimes a Competition Bureau filing in Canada, all running on separate statutory clocks that started on different days and that regulators will extend, pause, or restart with almost no warning. The lawyers running that process are not managing a single case file, they are managing a portfolio of deadlines that all point back to one transaction, and if one jurisdiction's clock gets missed while everyone was focused on another, the deal itself is exposed.

Layer a second request or an in-depth Phase 2 investigation on top of that timeline and the document problem becomes its own operational challenge. Antitrust productions are not measured in file folders, they are measured in hundreds of thousands or millions of pages, pulled from multiple custodians across multiple entities, reviewed by teams that rotate in and out over months, and produced under a schedule that a generic practice management tool was never built to hold. Most legal software on the market was designed around a single-matter, single-jurisdiction mental model: one case, one clock, one set of documents. Antitrust and competition practice breaks that model on day one.

Casely was built by watching how firms actually run matters, and antitrust work is one of the clearest cases where the gap between "generic case management" and "what this practice actually needs" shows up fast. The rest of this page walks through the specific features that matter for merger review timelines, multi-jurisdiction filings, and productions large enough to break a lesser system, using only what Casely genuinely does today.

Tracking merger review deadlines across every jurisdiction at once

The single biggest operational risk on a cross-border merger is not that anyone forgets the HSR waiting period. It is that the HSR clock, the CMA Phase 1 clock, and the EU Commission clock are all live simultaneously, each with its own extension rules, and the lawyer's attention naturally drifts toward whichever one is loudest that week. Casely's deadline diary attaches deadlines directly to the matter and uses next-date auto-tracking, which means the system always surfaces whichever date across the entire matter is coming due soonest, automatically, without anyone having to manually reorder a list.

That matters most on exactly the kind of deal this page is about, where a firm might be tracking a dozen or more statutory and self-imposed deadlines across a single transaction. A second request tolling agreement, a CMA extension, a substantial commitments deadline in Brussels, and an internal drafting deadline for the response brief can all be live in the same week. Next-date auto-tracking removes the need for a partner to hold the entire calendar in their head or trust that a paralegal's spreadsheet was updated after yesterday's call with opposing counsel. The deadline that matters most is simply what shows up first.

Linking a multi-jurisdiction filing without merging trust or billing histories

Antitrust work almost never fits neatly inside one matter number, because each regulatory filing has its own procedural history, its own document set, and often its own local counsel arrangement, even though it all serves one underlying transaction. Casely's connected matters feature lets you link the HSR filing, the CMA notification, and the EU Commission filing together with the reason for the connection stated plainly on each one, so anyone opening any single matter can see immediately that it is part of a larger deal and which other matters it relates to.

Crucially, connecting matters this way does not merge their billing or trust histories. The US filing can be billed hourly to the client's general counsel, the UK filing can run under a different fee arrangement with local counsel, and neither one contaminates the other's ledger or invoice history. That separation matters on real deals, where different entities within the same corporate family, or different outside counsel relationships in each jurisdiction, need genuinely distinct financial records even while the substantive matters stay visibly connected for anyone doing the legal work.

What a genuinely large document production requires from your systems

A second request production is not a document management problem in the way most practice areas think about it. It is hundreds of thousands of documents, pulled from multiple custodians, often across multiple corporate entities that are themselves parties to the underlying merger, reviewed by a team that grows and shrinks over the course of months. Every one of those documents needs to be secure, every one needs a clear record of who touched it and why, and none of it can live on shared infrastructure where a breach at one firm exposes another firm's clients.

Casely encrypts every document with AES-256 using a key specific to your firm, not shared across the platform's client base, so your production data is isolated at the encryption layer, not just behind a login screen. Every document also carries a comment field that records what changed and why, which on a production this size becomes the difference between a coherent chain of custody and a document set nobody can reconstruct six months later when opposing counsel challenges the completeness of the response. When a reviewer flags a document as privileged, redacts a portion, or reclassifies its responsiveness, that decision is recorded on the document itself, not buried in a separate tracker that someone has to remember to update.

A case file structure that matches how a merger review actually moves

Every merger review moves through recognizable stages, but the exact stages, and what happens at each one, differ by jurisdiction and by whether the deal draws a second request at all. A straightforward HSR clearance might move from filing to waiting period to clearance in thirty days. A deal that draws a second request adds substantial compliance, negotiation, and possibly litigation stages that can stretch the matter out for a year or more. A generic case management tool that assumes every matter follows the same four or five stages simply does not match this reality.

Casely's matter stage tracker is a clickable stepper at the top of the case file that is fully configurable per firm and per practice area, meaning your antitrust practice group can define stages that actually reflect a merger review, not stages borrowed from a litigation template that happens to also be on the platform. You can rename stages, reorder them, add a second request stage only where it applies, and remove stages that do not fit a particular deal, all without asking a vendor to customize anything for you.

Conflict checks that search the right years, not just this year

Antitrust and competition lawyers see the same handful of industry players again and again, sometimes as a client on one deal and as opposing counsel's client, a witness, or a competitor mentioned in a filing on the next. A conflict check that only searches active matters, or that only checks named clients, misses exactly the relationships that create real antitrust conflicts, where a party's past role as a witness, a joint venture partner, or a competing bidder years ago is precisely what needs to surface before you take on a new matter.

Casely's conflict checking searches the firm's full contact and matter history, not just active matters, and across every role a party played, not just named clients. That means a company that showed up as a third party in an unrelated merger review four years ago, or an individual who was deposed as a witness in a past investigation, will surface in a new conflict search if they show up again on a different matter. For a practice where the same set of large corporate players and their executives recur constantly, that depth of search is not a nice-to-have, it is the check that actually catches something.

Keeping deal teams and investigation teams out of each other's files

Large antitrust and competition practices routinely represent clients that compete with each other, or that sit on opposite sides of an industry the firm has deep relationships in. When that happens, an ethical wall around a specific matter has to actually hold, not just hide a case from a navigation menu while leaving it reachable through a search bar, a shared calendar entry, or a document link someone forwards without thinking about it.

Casely enforces ethical walls at the server itself, at the data access layer, not as an interface-level setting that a determined or careless user can route around. A walled staff member genuinely cannot reach a restricted matter through any path, whether they search for it by name, encounter it on a shared calendar, or receive a forwarded document link from a colleague who was not aware the wall existed. On antitrust matters, where the wall often exists precisely because two teams inside the same firm are working against each other's clients in different deals, that server-level enforcement is the part that actually matters.

Referral sources and regulatory contacts, tracked instead of remembered

Antitrust practices build relationships over years, with economists who serve as expert witnesses, with local counsel in other jurisdictions who get brought in on cross-border filings, with in-house counsel who refer new matters once they trust a firm's merger review work. Keeping track of who referred what, and who played what role on a past matter, tends to live in someone's memory rather than in a system, which is fine until that person leaves the firm or simply forgets.

Casely's contact labels let you tag a contact's role on a matter, whether that is a referral source, a witness, a related entity, or an opposing party, and referral sources specifically can be tracked over time. For a practice that depends on repeat referrals from in-house counsel and on a consistent bench of experts and local counsel across jurisdictions, having that history attached to the contact record itself, not scattered across email threads, turns institutional memory into something the whole firm can actually see and act on.

Billing corporate clients and insurers the way they actually want to be billed

The clients who fund antitrust and competition work are almost always sophisticated corporate legal departments or insurers, and they expect billing that matches their own systems, not whatever a firm's software happens to default to. A merger clearance might be billed flat fee for a straightforward HSR filing and hourly once a second request turns it into a multi-month investigation, sometimes on the same matter as the deal evolves.

Casely supports flat-fee, hourly, contingency, and blended billing models natively, so a firm does not need a workaround when a matter's billing arrangement changes partway through. LEDES 1998B export is supported for corporate and insurance e-billing, which matters directly for antitrust practice given how often the clients paying the bills are exactly the kind of institutional players who require it. And when it is time to actually invoice, turning a matter's billed time into an invoice is a single click that pulls every unbilled hour into one itemized draft, instead of a manual export-and-reformat process that eats an associate's afternoon before a bill can even go out.

Giving general counsel visibility without another email chain

The in-house counsel managing a merger review from the client side wants to know where things stand without asking, and without waiting for a status email that might not arrive until the end of the week. On a deal with filings in three jurisdictions, that visibility question multiplies, because the client wants to know the status of each jurisdiction's clock separately, not a single vague update covering everything at once.

Casely's client portal gives clients a filtered, real-time view of their own matter, including non-privileged documents, invoices, and status, and privilege filtering is automatic because it is tagged per document rather than something a paralegal has to manually curate before every client update. The portal works on mobile, which matters when the general counsel checking a filing's status is doing it from a phone between meetings, and e-signature works within that same client login, so signing off on a filing or an engagement letter does not require the client to create and remember a separate account just to put their name on a document.

Getting antitrust matter management live at your firm

None of this requires a procurement process or an IT department standing up servers. Casely is fully cloud-native, with no local install and nothing to provision, and it works from whatever device you happen to have open, whether that is a laptop in the office or a phone in an airport lounge between hearings in two different countries. A firm can start on the Free plan at no cost and see how the deadline diary, the connected matters structure, and the document security actually hold up against a real, active merger review before committing to anything larger.

The honest case for switching is not that a spreadsheet and a shared drive cannot technically track a merger review. It is that they were never built to survive the specific failure modes of this practice, a missed extension because two clocks were tracked in two places, a document that changed status with no record of why, a walled matter that turned out to be reachable through a forwarded link. Antitrust and competition work has less margin for that kind of quiet failure than almost any other practice area, because the cost of a missed deadline or a broken wall shows up in a regulator's decision, not just in an internal review.

If document security and production integrity are the part of this that keeps you up at night, it is worth looking directly at how Casely handles encryption and access control on the trust accounting and document security page, and if client-facing visibility across a multi-jurisdiction deal is the bigger gap at your firm right now, the client portal page walks through exactly how that real-time view works for a client managing filings in more than one country at once.
