Non-Liquidated Damages
Compensation for damages not predetermined or fixed by contract, assessed after a dispute in international investment law.
Updated April 23, 2026
How It Works in International Investment Law
Non-liquidated damages are a form of compensation awarded when the exact amount of loss or harm cannot be predetermined or specified within a contract. Unlike liquidated damages, which are fixed sums agreed upon by parties in advance, non-liquidated damages require a post-dispute assessment to determine the actual losses suffered. In the context of international investment law, this means that if an investor experiences harm due to a state's actions—such as unlawful expropriation or breach of treaty obligations—the amount of damages is calculated after considering the real impact rather than relying on a preset figure.
Why Non-Liquidated Damages Matter
In international disputes, especially those involving states and foreign investors, the complexity and unpredictability of harm often make it impossible to specify compensation amounts upfront. Non-liquidated damages provide a fair mechanism to ensure that injured parties receive appropriate redress based on actual losses. This approach respects the principle of full reparation under international law, aiming to restore the injured party to the position they would have been in if the wrongful act had not occurred.
Non-Liquidated vs. Liquidated Damages
A common point of confusion is the difference between non-liquidated and liquidated damages. Liquidated damages are stipulated in contracts as fixed sums payable upon breach, intended to simplify enforcement and avoid disputes over compensation. In contrast, non-liquidated damages are not predetermined; instead, they are assessed by tribunals or courts after evaluating the evidence of harm. This distinction is crucial because non-liquidated damages require detailed fact-finding and valuation, often involving complex legal and financial analysis.
Real-World Examples
A notable example involves the arbitration case between an investor and a state where the investor's assets were nationalized without adequate compensation. Since no liquidated damages clause existed, the arbitral tribunal had to assess the fair market value of the expropriated assets and consider consequential losses to determine the amount owed. This process exemplifies how non-liquidated damages function to provide equitable compensation in the absence of predefined contractual terms.
Common Misconceptions
One misconception is that non-liquidated damages are arbitrary or unpredictable. While their amounts are not fixed in advance, they are subject to rigorous legal standards and evidentiary requirements to ensure fairness and accuracy. Another misunderstanding is that non-liquidated damages apply only in domestic law; however, they play a significant role in international investment disputes where contractual terms may be silent or incomplete regarding compensation.
Example
In a landmark international arbitration case, an investor was awarded non-liquidated damages after the tribunal assessed the true market value of assets expropriated without prior compensation.
