One of the underused procedural tools in international arbitration is bifurcation — the decision to divide the proceeding into sequential phases rather than trying all issues at once. When used well, bifurcation can eliminate expensive quantum work before it begins, resolve threshold questions that might terminate the case entirely, and focus a complicated proceeding on the issues that actually matter. When used poorly, it extends timelines, duplicates costs, and frustrates the other side without producing the strategic benefit the requesting party anticipated. Understanding when to request bifurcation — and how to present that request persuasively — is part of experienced arbitration advocacy.
What Bifurcation Is
Bifurcation — or, in the case of three phases, trifurcation — is the procedural decision to divide the arbitration into sequential phases rather than addressing all issues in a single proceeding. The most common divisions are: (1) jurisdiction first, merits second; (2) liability first, quantum (damages) second; or (3) all three in separate phases. The tribunal issues a partial award or procedural order after each phase, and the next phase proceeds — or does not — depending on the outcome.
Bifurcation is a tribunal prerogative under most institutional rules. It requires the tribunal's decision, not just the consent of one party. Either party may request bifurcation, and the tribunal decides whether to grant it after considering the likely efficiency gain, the potential for prejudice, and whether the issues proposed for separation are genuinely independent of one another.
Jurisdictional Bifurcation — Challenging the Tribunal's Authority to Hear the Case
The most common application of bifurcation is the preliminary jurisdictional phase. When a respondent believes the tribunal lacks jurisdiction — because the arbitration agreement is invalid, the dispute falls outside the clause's scope, the claimant lacks standing, or the claim is time-barred — it can request that the tribunal rule on jurisdiction before addressing the merits.
Jurisdictional objections under ICC, ICDR, and JAMS rules must typically be raised early — in the answer or the first substantive submission. Failure to raise them promptly can result in waiver. A respondent that participates in merits proceedings without asserting jurisdictional objections may find that it has consented to the tribunal's authority by conduct.
A successful jurisdictional objection terminates the arbitration. The potential upside for a respondent is enormous; the risk is that the tribunal rejects the objection and the respondent has spent substantial time and money on a preliminary hearing that resolved nothing other than confirming the tribunal's authority to continue. Jurisdictional bifurcation is worth requesting when the objection is strong and genuinely dispositive — not as a delay tactic. Tribunals are experienced enough to recognize strategic use of preliminary phases, and a weak jurisdictional objection pursued primarily to delay the proceeding may result in cost consequences.
Liability/Quantum Bifurcation — Separating Who Owes from How Much
Liability/quantum bifurcation is the more commercially significant form. It separates the question of whether the respondent is liable from the question of how much it owes. A tribunal that finds no liability in Phase 1 terminates the arbitration without the parties having spent the time and resources to develop, brief, and present a full damages case.
The efficiency argument for bifurcation is strongest when: (a) the liability case is genuinely close — if one side clearly breached, neither party benefits from deferring the damages case; (b) the damages analysis is complex and expensive — quantum cases involving financial models, lost profits analysis, and multiple expert reports can cost millions of dollars; and (c) the liability questions can be heard and decided in substantially less time than the full case would require.
The argument against bifurcation is that it extends the total timeline. Two hearings over a period of years rather than one. In a case that takes three years in a single proceeding, bifurcation might take five. For claimants who want a recovery sooner rather than later — particularly when cash flow is a concern or the underlying commercial relationship has already ended — bifurcation is rarely attractive. Claimants generally prefer to present the full case, win on liability and quantum together, and enforce an award that addresses both.
Procedural Considerations When Requesting Bifurcation
The request should be made as early as possible — at the first case management conference if possible, and certainly before the procedural timetable is set for the full merits phase. Raising bifurcation after the parties have already invested substantially in quantum preparation weakens the efficiency argument and signals to the tribunal that the request is tactical rather than genuinely efficiency-driven.
The requesting party should be prepared to explain: what specific issues would be addressed in each phase; why those issues are sufficiently independent that resolving Phase 1 might terminate or significantly narrow Phase 2; what the realistic time and cost savings are if Phase 1 goes in the requesting party's favor; and whether the other party would be prejudiced by the separation — for example, if key witnesses are relevant to both phases and requiring them to testify twice is unduly burdensome or practically impossible.
Tribunals frequently decline to bifurcate when the issues overlap substantially. When the same factual record is needed for both phases — the same witnesses, the same documents, the same expert analysis — bifurcation produces duplicative rather than sequential proceedings. A bifurcation request that would require two complete evidentiary hearings addressing the same core facts rarely survives scrutiny.
Strategic Considerations for U.S.-LATAM Disputes
For disputes involving parties from Latin American jurisdictions, bifurcation of jurisdiction may be particularly strategic in two situations: (1) the respondent genuinely disputes whether the arbitration clause is enforceable under the applicable law — for example, whether a clause in a standard-form contract binds a party who did not negotiate it under local consumer protection law; or (2) the respondent wants to challenge the enforcement of a foreign arbitral award in a local court, which sometimes requires the local proceeding to await the outcome of a jurisdictional challenge in the arbitration itself.
Liability/quantum bifurcation is often appropriate in LATAM disputes where the damages case requires expert testimony on local market conditions, lost profits in local currency, or LATAM-specific valuation methodologies — all of which are expensive to develop and require local expertise that takes time to retain and prepare. If liability is genuinely uncertain, deferring that investment until liability is confirmed makes practical and financial sense. A respondent that faces a contested LATAM market damages case involving multiple jurisdictions and industries can easily spend $500,000 or more on quantum experts alone — expenditure that bifurcation might eliminate entirely if the liability phase resolves in its favor.
Finally, bifurcation can serve a discovery function. The liability phase record — witness testimony, cross-examination, document production — often surfaces information that affects how a party approaches the quantum phase. Knowing what the tribunal found persuasive on liability, and how key witnesses performed under examination, informs the damages strategy in ways that cannot be anticipated before the first hearing.
