How are arbitration lawyers sourcing disputes earlier today?
Arbitration teams now look for international arbitration leads earlier than they used to. Instead of waiting for a case to reach a registry, business-development staff and associates watch the government action itself: a licence pulled, a tax imposed, a decree signed. Then they watch what the investor does next. The International Centre for Settlement of Investment Disputes (ICSID) registered 63 new cases in 2025, the second-highest year on record.
Each one started with a government action long before there was a claim to find. Our investment treaty arbitration guide sets out that sequence.
By the time ICSID registers a case it has usually screened the request in about three weeks and put the basic details online. The investor has already hired counsel.
No single register shows the whole market. UNCTAD's Investment Dispute Settlement Navigator counted at least 56 publicly known treaty cases started across all arbitration institutions in 2025, and more than 400 since 2020. That count is kept separately from ICSID's registrations, and UNCTAD says the real number is higher. A firm that reads only registries joins every conversation late, after the investor has chosen counsel. See how to detect investment treaty disputes early for which signals to watch.
How did practices find investment disputes before?
For years, referrals, conference talk and registry announcements did most of the work, with specialist arbitration news filling the gaps. All of it shows a dispute only after the investor has decided to act. That is no longer enough.
ICSID posts the basic facts of a new case the moment it registers a request, and every major step follows in that case's file. The UNCITRAL Transparency Registry works the same way: it publishes the parties, the sector and the treaty once arbitration begins. Both are official, and both come too late. Referrals still bring the best work; what they miss is the months when the mandate was still open.
Why has dispute sourcing moved earlier?
Sourcing moved earlier because the decision that matters, which firm drafts the notice of dispute, is made during the cooling-off period. About 90% of bilateral investment treaties (BITs) make an investor wait before going to arbitration, and six months is the most common wait. The clock starts the day a formal notice of dispute is served.
Eiser Infrastructure and Energía Solar Luxembourg reached ICSID five months after Spain's Royal Decree-Law 9/2013 cut renewable tariffs (ICSID Case No. ARB/13/36). Nachingwea and others v. Tanzania (ICSID Case No. ARB/20/38) took about two years to reach ICSID after the 2018 mining regulations cancelled retention licences. The numbers make the window worth watching: those 63 ICSID registrations in 2025 were the second-highest total on record, and the ICSID caseload trends for 2026 show where they concentrate.
What kinds of tools do arbitration teams use, and what does each miss?
Four kinds of tool exist, and each one picks up a dispute at a different moment.
- A treaty and case database is complete and easy to search once a case is public. But a dispute only enters it after a filing, an award or a settlement, which is already the end of the sourcing window.
- An arbitration news service reports registrations and settlements once an editor decides the story matters, usually weeks after the government action that caused it.
- A registry alert arrives the day ICSID or another institution posts a new case. It is fast at that moment and sees nothing before it.
- Signal-based monitoring reads news, official gazettes, ministry announcements and stock-exchange filings, usually in the local language. It can flag the government action months before it becomes a case. The downside is noise, so it only works with a screening step that cuts the volume down to what a person can act on.
Even the best of these works with incomplete information. UNCTAD's Navigator update from January 2026 says its own known-case counts are probably below the real total, and get revised upward as cases come to light late. No single source sees everything.

How should a firm evaluate a dispute-sourcing tool?
Five things separate a tool a firm keeps from one it ignores.
- Which countries and languages it actually reads.
- How far ahead of the registry it runs.
- How much noise reaches the partner.
- How much research comes attached to each lead.
- Who inside the firm is responsible for working the list every week.
In our experience, the last point decides whether a tool pays for itself. A feed nobody owns becomes an unread folder within a month, however wide its coverage. Speed matters too: ICSID posts a new case within three weeks of screening, so a tool that starts there has already missed the window. None of this replaces the relationships a partner has built. It changes which conversation happens first.
What this means for practice
The practical move is to give one person the job and pick sources by sector and region, around the mandates the firm wants. Measure the team on the notices of dispute it saw coming before they were served. Monitoring tools such as DSPT Finder read news, government publications and company disclosures in 32 languages across more than 159 countries, and turn them into international arbitration leads. They surface freshly served notices of dispute early enough for a business development team to act before the request for arbitration is filed. Litigation funders can use the same signals for investment treaty claim sourcing.

Frequently asked questions
What does sourcing a dispute early mean in international arbitration?
Sourcing a dispute early means finding a possible investor-state claim while the government action behind it is still fresh, before a notice of dispute is served and before any registry or news service reports the case. Counsel gets there first.
What is the difference between a case database, a news service and signal-based monitoring?
A case database records disputes once they are already public. A news service reports filings an editor has chosen to cover. Signal-based monitoring reads government publications, local press and company disclosures to flag the government action first.
How quickly does ICSID make a new case public?
ICSID screens a new request for arbitration in about three weeks on average, then posts the basic case details once the case is registered. Every major step is published afterwards in that case's file.
Who in a law firm is usually responsible for spotting new disputes?
It varies by firm. Partners hear of work through relationships built over years, associates follow registries and arbitration news, and business-development teams increasingly run structured monitoring for international arbitration leads. Firms that do this well give one person the job and a fixed weekly routine.
How can a firm monitor for early signals before a notice of arbitration is filed?
By reading official gazettes, ministry and regulator announcements, mining registries, stock-exchange filings and local-language press across the countries a practice covers. Screen each item for the treaty protections it might trigger, before any filing exists to find.
