The Singapore Convention on Mediation – the multilateral treaty that gives international mediated settlement agreements direct cross-border enforcement force – gained new signatory and ratifying states in 2026, expanding the network of jurisdictions where such agreements can be relied upon without separate litigation. Companies operating across multiple jurisdictions should review their dispute resolution strategies now, since the practical effect of each new ratification is that a settlement agreement reached through mediation may become enforceable in those states as a matter of treaty obligation rather than domestic contract law alone. The window for taking preventive action – before a dispute escalates to formal proceedings – is narrowing as the Convention's reach grows and counterparties in newly covered jurisdictions gain new procedural options.
Background: What the Singapore Convention Does
Adopted in 2019 under the auspices of the United Nations Commission on International Trade Law (UNCITRAL), the Singapore Convention on Mediation establishes a framework for the recognition and enforcement of international commercial settlement agreements resulting from mediation. Before the Convention, a party holding a mediated settlement had, in most jurisdictions, nothing more than a contract: enforcement required fresh court proceedings in each territory where assets were located.
The Convention changes that calculus materially. A party may apply directly to a competent authority in any contracting state for relief – either enforcement of the settlement or, in defence of existing proceedings, invocation of the settlement as a bar. The result is that mediation begins to occupy a position structurally comparable to arbitration, where the New York Convention (1958) has long provided a cross-border enforcement mechanism.
For a fuller analysis of how the Convention reshapes enforcement options, see our earlier briefing: Singapore Convention on Mediation – Finally Enforceable.
What Changed in 2026
New states formally joined the Convention as parties in 2026, extending the geographic scope of treaty-based enforcement. While the identities of all new parties are subject to final depositary confirmation, the expansion signals continued momentum toward a genuinely global regime for mediated settlement agreements.
Key points to keep in mind about the current landscape:
- United Kingdom: The UK signed the Convention in 2023 and subsequently opened a public consultation on ratification. As of the date of this alert, ratification is pending; the domestic implementing legislation required before the Convention takes effect in UK courts has not yet been enacted. Companies with UK counterparties or UK-sited assets should monitor the ratification process closely.
- European Union: The EU has not ratified the Convention, and individual EU member states are generally not in a position to ratify independently in an area where EU competence may be engaged. The position of EU-based counterparties and EU-sited assets therefore remains governed by domestic contract and procedural law, not the Convention.
- New 2026 parties: Their specific implementation rules – including any reservations entered, the treatment of government parties, and national procedural requirements – are subject to each state's national rules and, where not yet gazetted, should be treated as pending confirmation.
Who Is Affected
The expansion is directly relevant to any company that:
- holds or may hold a settlement agreement reached through mediation with a counterparty whose assets are located in a newly acceding state;
- is currently in a pre-litigation dispute and is considering whether to propose or accept mediation as a resolution mechanism;
- has existing contracts that include dispute resolution clauses referring only to arbitration or litigation, without addressing mediation;
- is engaged in restructuring negotiations – where a standstill agreement or structured payment plan may ultimately be formalised through a mediated process – and needs certainty about cross-border enforceability; or
- has received or is preparing a letter before action in a jurisdiction that has now ratified the Convention, where the opposing party may seek to invoke mediation as a pre-litigation step to lock in a settlement under the treaty framework.
If your business falls into any of these categories, we would recommend a preliminary review of your dispute resolution exposure. Please contact our team at info@ferrazwhitmore.com or visit our contacts page to arrange a consultation.
Immediate Action Items for International Companies
The following steps are prudent in light of the 2026 developments:
- Map your exposure: Identify all pending and potential disputes, ongoing standstill agreements, and active payment plans that involve counterparties or assets in states that have now ratified the Convention. The enforceability landscape for any mediated settlement agreement concluded going forward is materially different from what it was before.
- Review dispute resolution clauses: Contracts drafted before the Convention entered force in a given jurisdiction may contain arbitration or litigation clauses with no mediation step. Consider whether renegotiation or addendum drafting is warranted, particularly in high-value commercial relationships.
- Assess pre-litigation strategy: If you are at the pre-litigation stage – whether or not a letter before action has been issued – the availability of treaty-backed mediation may alter the risk-benefit analysis of each path. A settlement reached now, properly documented and qualifying under the Convention, could be enforceable across a wider set of jurisdictions than a court judgment obtained later.
- Verify national implementation rules: Each contracting state may enter reservations and will apply its own procedural requirements to enforcement applications. Do not assume that ratification translates automatically into straightforward enforcement without checking national rules in the relevant jurisdiction.
- Monitor UK and EU developments: The UK's ratification process and any future shift in the EU's position could affect enforcement options for a large proportion of cross-border commercial disputes. Build a monitoring obligation into your contract management processes.
Interaction with Restructuring and Insolvency Contexts
One area where the Convention's expansion has practical significance is cross-border restructuring. Where negotiations involve a standstill agreement, a payment plan, or a debt compromise, parties sometimes use mediation to structure a binding resolution before formal insolvency proceedings are commenced. If the resulting settlement agreement qualifies under the Convention, it may be enforced in multiple jurisdictions without the need to obtain separate court judgments – a meaningful advantage where time and asset preservation are critical.

Germany and Other Key Commercial Hubs
For companies with significant commercial relationships in Germany – where structured negotiation and mediation have a well-established role in commercial dispute resolution – the Convention's expansion is particularly worth evaluating in the context of existing and future contracts. Our team advising on commercial negotiations in Germany can assist in aligning dispute resolution strategy with the evolving international framework.
Next Steps
The growth of the Singapore Convention's membership is not merely a treaty development to note and file. For companies with cross-border commercial exposure, it changes the enforceability of mediated settlement agreements, the strategic value of pre-litigation mediation, and the risk profile of disputes left unresolved. Acting before a dispute crystallises – rather than after a letter before action has been received – gives considerably more room to shape the outcome.
