How to Enforce a Mediated Settlement Abroad

Enforcing a mediated settlement agreement in a foreign jurisdiction requires identifying the correct legal basis – most often the Singapore Convention on Mediation (2019), a bilateral investment treaty, or local contract law – and then satisfying the procedural requirements of the enforcing court or authority. The process differs materially depending on whether the target country has ratified the Singapore Convention, is an EU member state, or relies solely on domestic contract enforcement mechanisms. Understanding these distinctions before a dispute arises can save considerable time and cost if the counterparty later fails to perform.

The Legal Landscape: Why Enforcement of Mediated Settlements Is More Complex Than Arbitral Awards

Unlike arbitral awards, which benefit from the well-established New York Convention framework in over 170 contracting states, mediated settlement agreements have historically had to rely on domestic contract law or be converted into court judgments or consent awards. A creditor seeking to enforce abroad often had to commence fresh litigation in the foreign jurisdiction – an expensive and slow process that undermined the commercial rationale of choosing mediation in the first place.

The Singapore Convention on Mediation, which entered into force in 2020, introduced a dedicated international treaty mechanism for the direct enforcement of international mediated settlement agreements without the need to re-litigate the underlying dispute. As of 2026, the convention has attracted new signatories and parties, reflecting growing acceptance of mediation as a cross-border dispute resolution tool. However, the convention's coverage remains uneven: the EU has not ratified it, meaning enforcement within EU member states still falls outside the convention framework.

The UK signed the Singapore Convention in 2023 and subsequently consulted on ratification, but the process has not been concluded. Practitioners advising clients on settlements with UK counterparties should therefore treat the convention as a prospective tool rather than an available one, and plan enforcement using domestic English law routes in the interim.

Step-by-Step Enforcement Procedure

Step 1 – Confirm the Agreement Qualifies

The Singapore Convention applies to international mediated settlement agreements: those concluded between parties whose places of business are in different states, or where the jurisdiction of performance or the subject matter is connected to more than one state. Purely domestic settlements are outside scope. Before committing to a convention-based enforcement strategy, verify:

• the settlement is in writing and signed by the parties;
• it arose from mediation (the process was facilitated by a neutral third party);
• it resolves a commercial dispute (certain categories, including consumer, family and employment matters, are excluded);
• the target enforcement jurisdiction is a convention party and has implemented the treaty domestically.

Step 2 – Gather the Required Documents

Under the Singapore Convention, the party seeking enforcement must submit the signed settlement agreement and evidence that the agreement resulted from mediation. The convention specifies that the mediator's signature on the agreement, or a separate attestation by the mediating institution, can serve as that evidence. Most implementing states require certified translations into the local language. Standard document requirements typically include:

• the original or certified copy of the settlement agreement;
• evidence of the mediation process (institutional certificate, mediator attestation or equivalent);
• certified translation into the official language of the enforcing jurisdiction;
• legalisation or apostille where required by national rules;
• a statement identifying the obligation to be enforced and, where applicable, confirmation of partial non-performance.

Where the settlement has also been recorded as a consent order or converted into an award, obtain and attach that document as well – some jurisdictions will find enforcement easier via a recognised judgment route.

Step 3 – Identify the Competent Authority

Each convention state designates its own competent courts or authorities to receive enforcement applications. This information is published through the Singapore Convention's depository, UNCITRAL. In jurisdictions where implementation legislation is pending or incomplete, applicants may need to proceed under general civil procedure rules and frame the application as enforcement of a foreign contractual obligation. In EU member states, where the convention does not apply, enforcement proceeds through domestic courts using contract law or, where a court has approved the settlement, through applicable EU judgment-recognition instruments.

Step 4 – File the Application and Manage the Timeline

Once documents are assembled, the application is filed with the competent authority. The convention does not prescribe a single timeline; national procedural rules govern how quickly an enforcing court must act. In practice, timelines vary significantly. A jurisdiction with a streamlined summary enforcement procedure may resolve an uncontested application within a few months; a jurisdiction where enforcement is contested and requires full adversarial proceedings may take considerably longer. Identifying early whether the counterparty is likely to raise grounds of objection – such as incapacity, procedural irregularity in the mediation, or public policy – is critical to realistic timeline planning.

If your dispute involves a counterparty in financial difficulty, it is worth considering whether enforcement action might coincide with insolvency proceedings. Our guide on bankruptcy and restructuring considerations provides relevant context for creditors facing this scenario.

Step 5 – Address Grounds of Refusal Proactively

The Singapore Convention allows an enforcing authority to refuse enforcement on limited grounds, broadly mirroring those in the New York Convention for arbitral awards. Key grounds include:

• Incapacity: a party was under some incapacity at the time of the settlement;
• Invalidity: the agreement is null, void or inoperative under the applicable law;
• Procedural irregularity: serious deviation from the standards agreed between the parties or applicable to the mediator;
• Mediator standards: the mediator breached applicable standards without which the party would not have entered into the settlement;
• Public policy: enforcement would be contrary to the public policy of the enforcing state;
• Non-binding or already performed: the obligations have already been complied with, or the agreement is not binding or not final.

The best preparation against these grounds is meticulous documentation during the mediation itself: record the mediator's qualifications, the procedural steps followed, any independent legal advice received by both parties, and confirmation of informed consent to the terms. Parties who cut corners during the mediation process tend to pay a disproportionate cost at the enforcement stage.

Enforcement in EU Member States: The Contract Law Route

Because the EU has not ratified the Singapore Convention, enforcement of an international mediated settlement within EU member states requires a different approach. The EU Mediation Directive (2008/52/EC) and its national implementing legislation facilitate enforceability of mediated settlements in domestic and cross-border civil and commercial disputes within the EU, but the mechanisms vary. In most member states, the parties may request that the settlement be approved by a court or authenticated by a notary, making it directly enforceable as a court order or notarial deed. Where this has not been done, the settlement functions as a contract, and enforcement requires commencing a claim for breach of contract if the counterparty does not perform.

For clients with ongoing commercial relationships in France, proactive structuring of dispute resolution clauses – including how a mediated settlement will be recorded and made enforceable – is an important pre-litigation step. Our team advising on commercial negotiations in France can assist with this structuring work before a dispute escalates.

Pre-Litigation and Practical Protective Steps

Enforcement begins, in practice, well before any application is filed. Parties should consider a number of pre-litigation measures when the prospect of non-performance first arises:

• Letter before action: a formal letter before action identifying the obligation, the breach and the intended enforcement steps – this creates a record, may prompt voluntary compliance, and is expected in many jurisdictions before proceedings begin.
• Standstill agreement: if the counterparty is experiencing financial difficulty, a short standstill agreement preserving the parties' positions while restructuring options are explored can avoid an enforcement race that benefits neither party.
• Payment plan: where the counterparty acknowledges liability but cites cash-flow constraints, a structured payment plan agreed in writing may be preferable to enforcement proceedings, particularly where the counterparty's assets are difficult to locate or attach.
• Asset tracing: identify the counterparty's reachable assets in the target jurisdiction before committing to enforcement; a favourable enforcement order against a counterparty with no attachable assets in that jurisdiction produces a hollow result.

Cost Drivers and Common Errors by Foreign Clients

The cost of cross-border enforcement of a mediated settlement is shaped by several variables: the number of jurisdictions involved, whether translations and apostilles are needed, the complexity of the underlying obligation, and whether the counterparty contests the enforcement. The following are the most common errors encountered in practice:

• Failing to record the mediation adequately: settlement agreements that do not contain evidence of the mediation process on their face – or are not accompanied by an institutional certificate – create avoidable documentary gaps at the enforcement stage.
• Assuming the Singapore Convention applies universally: clients sometimes proceed on the assumption that a signed convention-compliant agreement can be enforced anywhere, without checking whether the target jurisdiction has ratified and implemented the convention. In countries where implementation is pending or absent, the application will fail or require reframing.
• Overlooking EU-specific routes: in EU member states, seeking court approval or notarial authentication of the settlement at the time it is concluded is far cheaper than commencing fresh litigation later. Many clients miss this window.
• Delayed action: limitation periods in the enforcing jurisdiction begin running from the date of breach, not from the date of the original dispute. Waiting too long to act can extinguish otherwise valid claims.
• Inadequate translation: non-certified or machine-generated translations are rejected by courts in most jurisdictions, causing delay and additional cost.

Decision Checklist Before Filing

Before committing to a formal enforcement application in any jurisdiction, work through the following questions:

• Has the target jurisdiction ratified the Singapore Convention and enacted implementing legislation?
• Does the settlement agreement meet the convention's formal requirements (written, signed, evidence of mediation)?
• Are certified translations and apostilles in order?
• Has a letter before action been sent and the response (or silence) documented?
• Have the counterparty's attachable assets in the target jurisdiction been identified?
• Are there parallel insolvency or restructuring proceedings in any relevant jurisdiction?
• Is the relevant limitation period in the enforcing jurisdiction still open?
• Has local counsel in the enforcement jurisdiction been engaged?

Working With Local Counsel

Cross-border enforcement of mediated settlements almost always requires the involvement of qualified local counsel in the enforcing jurisdiction. The role of international coordinating counsel – such as Ferraz & Whitmore – is to structure the overall strategy, manage document preparation, coordinate across jurisdictions and ensure that procedural steps taken in one country do not inadvertently prejudice the position in another. Local counsel handles the court filings, appears at hearings and advises on jurisdiction-specific nuances that can determine the outcome of an otherwise well-prepared application.

The combination of coordinating and local counsel is particularly important in multi-jurisdictional enforcement scenarios, where a counterparty may hold assets in several countries and enforcement actions must be sequenced or run in parallel without triggering cross-border insolvency considerations prematurely.
