How Belgium's 2026 Civil Code Loan Reform Will Change Lending, What Banks and Credit Teams Must Do

On 22 May 2026, the Belgian government published a draft for consultation that proposes inserting a new Title 5 into Book 7 “Special Contracts” of the Civil Code, overhauling the existing regime on loans with interest (lening op interest / prêt à intérêt). This loan reform in Belgium arrives on top of the personal-security rules that already took effect on 1 January 2026, creating a double wave of compliance obligations for every institution that originates, services or enforces credit in the Belgian market. The consultation draft introduces mandatory disclosure duties, proportionality requirements and strengthened guarantor protections that will touch consumer loans, mortgages and commercial lending alike.

For in-house counsel, bank compliance officers, credit-risk managers and external advisers, the practical question is not whether to act but how quickly. The five actions below form the skeleton of the compliance programme every Belgian lender should be building right now:

• Audit all template loan agreements and guarantee forms against the draft’s new formality and disclosure requirements.
• Update pre-contractual disclosure notices and affordability-assessment records.
• Reassess enforcement playbooks, notice periods, repossession steps and insolvency interfaces are changing.
• Re-document high-value existing suretyships to address new guarantor-protection rules already in force.
• Train front-line credit, legal and operations teams before the final text is adopted.

What Is Changing, Quick Summary of the 2026 Civil Code Loan Reform

Belgium’s ongoing modernisation of the Civil Code has already delivered new books on property law (Book 3, in force since 2022) and obligations (Book 5, in force since 2023). The May 2026 consultation draft extends that reform into the heart of lending law by creating a dedicated Title within Book 7, “Special Contracts”, that codifies and updates the rules on loans with interest. According to the summary published by CMS, the draft sets out core principles on how loan contracts are formed, how interest may be charged, what information must be provided before and during the life of the loan, and how guarantees securing the loan must be structured.

Separately, a reform of personal-security rights, covering suretyship, independent guarantees and related instruments, entered into force on 1 January 2026, as confirmed by KPMG Law Belgium. That earlier reform already imposes new mandatory-information obligations on creditors and grants guarantors the right to terminate indefinite guarantees. The May 2026 loan-rules draft therefore sits alongside, and must be read together with, the personal-security rules that are already live.

Key Dates and Status

• 1 January 2026: New Civil Code rules on personal security rights (suretyship, guarantees) entered into force.
• 22 May 2026: Government published draft consultation on loan rules (new Title 5, Book 7).
• Consultation period: Open, final text and effective date not yet confirmed. Industry observers expect a six-month implementation window once the law is published in the Belgisch Staatsblad / Moniteur belge.

Who and Which Products Are Affected by the New Belgium Loan Rules

The draft consultation is product-agnostic in scope: it applies to any contract that qualifies as a loan with interest under Belgian law. That breadth means consumer lenders, mortgage originators, commercial banks, real-estate finance desks and structured-lending teams must all evaluate the impact. The table below maps the three main product categories to their most significant proposed changes and the immediate action required.

Securitisation vehicles and fund-finance structures that hold Belgian-law loans must also check whether the new rules apply to the underlying receivables or to any back-to-back guarantees given by originators. Industry observers expect the reform to have ripple effects on loan-trading documentation, particularly where guarantees form part of the collateral package.

Immediate Lender Obligations, 5 Actions to Take This Quarter Under the Loan Reform in Belgium

Even though the loan-rules draft is still at consultation stage, the personal-security reforms are already binding. Waiting for the final text is not an option: lender obligations in Belgium have already expanded, and further changes are certain. The five priority actions below should be treated as concurrent workstreams.

• 1. Audit template agreements and guarantees. Compare every standard-form loan agreement, guarantee deed and suretyship template against the requirements in force since 1 January 2026 and the requirements proposed in the May 2026 draft. Flag any clause that conflicts with mandatory rules on disclosure, guarantor consent or proportionality. Owner: Legal / Documentation team. Target: 30 days.
• 2. Update mandatory disclosure notices. The reforms impose specific information duties, both pre-contractual and ongoing, that must be delivered in writing and in a prescribed format. Draft updated disclosure templates for each product line, have them reviewed by external counsel, and deploy them into the origination workflow. Owner: Compliance. Target: 45 days.
• 3. Reassess affordability and proportionality checks. For consumer credit in Belgium, the draft reinforces the lender’s duty to verify that the borrower can service the loan without undue hardship. Document the methodology, data sources and decision criteria used in every affordability assessment. Owner: Credit Risk. Target: 60 days.
• 4. Update the enforcement playbook. Enforcement of loans in Belgium is changing in two respects: guarantors now have termination rights and new notice periods, and the draft proposes additional pre-enforcement procedural steps for borrowers. Map out every enforcement pathway (court proceedings, extrajudicial enforcement, insolvency filings) and incorporate the new timelines. Owner: Legal / Litigation. Target: 60 days.
• 5. Train and sign off. Conduct mandatory training sessions for all staff involved in loan origination, servicing and enforcement. Require written sign-off confirming that each team member has understood the new requirements. Owner: Compliance / HR. Target: 90 days.

Sample Project Plan, 30 / 60 / 90 Days

• Days 1–30: Complete template audit; appoint executive sponsor; finalise external-counsel engagement for drafting review.
• Days 31–60: Deploy updated disclosure templates; recalibrate affordability models; revise enforcement playbook.
• Days 61–90: Training rollout; first compliance-monitoring report to board or risk committee; gap analysis for IT system changes (document management, automated disclosure triggers).

Loan Drafting Checklist, Contract Clauses Lenders Must Update

The civil code loan reform requires lenders to revisit the architecture of their standard-form agreements. Below is a loan drafting checklist of six clause categories that demand attention, together with indicative sample language. All samples are for illustrative purposes only and must be adapted by qualified Belgian counsel before use.

• Loan definition and classification clause. Ensure the agreement explicitly identifies itself as a loan with interest within the meaning of the new Title 5, Book 7 of the Civil Code, to remove any ambiguity about which regime applies. Sample: “This Agreement constitutes a loan with interest (lening op interest / prêt à intérêt) governed by Book 7, Title 5 of the Belgian Civil Code.”
• Interest-mechanics clause. State the basis for interest calculation (fixed, variable, reference rate), the frequency of capitalisation and any limits imposed by mandatory law on compound interest. The draft reinforces the principle that interest clauses must be transparent and not disproportionate. Sample: “Interest shall accrue at [rate]% per annum on the outstanding principal, calculated on an actual/365 basis, and shall not be capitalised more frequently than [annually].”
• Borrower representations and information duties. Include a representation that the borrower has received all pre-contractual information required under the Civil Code and any applicable consumer-credit legislation. Sample: “The Borrower acknowledges receipt and review of the Pre-Contractual Information Sheet provided at least [X] days prior to execution of this Agreement.”
• Guarantor notice and consent clause. Under the personal-security rules in force since 1 January 2026, guarantors must give informed consent in a prescribed form. The clause must also reference the guarantor’s right to terminate indefinite guarantees. Sample: “The Guarantor confirms that it has received and understood the Information Notice annexed hereto and consents to the guarantee on the terms set out in Schedule [X], acknowledging its right to terminate this guarantee in accordance with Article [ref] of the Civil Code.”
• Disclosure and ongoing-information clause. Embed a contractual obligation on the lender to provide periodic information to both borrower and guarantor as required by mandatory law. Sample: “The Lender shall provide the Borrower and each Guarantor with an annual statement setting out the outstanding principal, accrued interest and any amounts in arrears.”
• Early termination, hardship and renegotiation clause. Address the new hardship provisions codified in Book 5 of the Civil Code and anticipated in the loan-rules draft. Include a renegotiation mechanism that references the statutory framework. Sample: “If a change of circumstances unforeseeable at the date of this Agreement renders performance excessively onerous for either party, the affected party may request renegotiation in accordance with Article 5.74 of the Civil Code. Pending renegotiation, obligations under this Agreement remain in full force.”

Guarantees, Guarantors and Personal Security Rights, Practical Impacts

The reform of lender security rights in Belgium is arguably the area of greatest operational risk for banks. The personal-security rules that entered into force on 1 January 2026 introduced three headline changes that creditors must now manage on every existing and future guarantee.

First, creditors face new mandatory information obligations toward guarantors. They must disclose the nature and extent of the guaranteed obligation, the risks involved and the guarantor’s rights, before the guarantee is signed and at prescribed intervals thereafter. Second, guarantors can now terminate indefinite guarantees, with practical guidance from Bird & Bird indicating a 45-day notice mechanism. Third, the proportionality principle now applies: a guarantee that is manifestly disproportionate to the guarantor’s financial capacity may be challenged.

Practical Drafting Changes for Guarantees

• Replace open-ended guarantee language with a defined maximum guaranteed amount and, where possible, a fixed term.
• Include a standalone “Guarantor Information Notice” as a schedule, signed separately by the guarantor, confirming receipt and understanding of all mandatory disclosures.
• Add a clause addressing the termination right: specify the notice period, the form of notice and the obligations that survive termination.
• Ensure all guarantees contain a proportionality acknowledgement, recording the guarantor’s financial position at the date of execution.

How to Re-Document Existing Suretyships

For high-value guarantees entered into before 1 January 2026, BDO Belgium recommends that banks review each suretyship agreement against the new mandatory requirements and prioritise re-documentation where there is a disclosure or formality gap. The likely practical effect will be a phased triage: guarantees above a defined exposure threshold are reviewed first, followed by portfolio-wide remediation. Banks should also consider whether to approach guarantors proactively to request updated financial information, which both satisfies the proportionality record-keeping obligation and strengthens the enforceability of the guarantee.

Mortgage Lending Compliance and Enforcement Playbook

Belgium’s mortgage market has been robust, Febelfin data shows that Q1 2026 was among the four strongest year-starts in the past decade. Against that backdrop, the enforcement of loans in Belgium secured by mortgage is evolving in ways that demand immediate attention from litigation and credit-recovery teams.

The draft consultation proposes procedural safeguards that supplement existing enforcement routes. Industry observers expect these to include enhanced pre-enforcement notice requirements, mandatory borrower-engagement steps and tighter timelines for court-supervised enforcement. The table below compares the current enforcement pathway with the direction of travel under the proposed rules.

Banks should map their existing enforcement workflows step by step and identify each point where the proposed rules add a new procedural obligation. Early indications suggest that lenders who fail to follow the pre-enforcement engagement requirements may face challenges to the validity of subsequent enforcement steps.

Consumer-Credit Specific Changes, Affordability, Disclosure and Remedies

Consumer credit in Belgium is already subject to stringent regulation under the Consumer Credit Act and the transposition of the EU Consumer Credit Directive. The 2026 loan-rules draft layers additional obligations on top of that existing framework, particularly in three areas.

• Affordability and proportionality. The draft reinforces the lender’s duty to conduct a meaningful assessment of the borrower’s ability to repay. Lenders must document not only the data inputs (income, existing debt, household expenses) but also the analytical methodology and the decision rationale. This goes beyond a simple debt-to-income check.
• Pre-contractual disclosure. In addition to the European Standard Information Form already required under consumer-credit legislation, the draft proposes that lenders provide a supplementary disclosure document setting out the borrower’s rights under the new Civil Code provisions, including the right to request renegotiation in cases of hardship.
• Remedies and cooling-off. The draft strengthens the borrower’s right to challenge disproportionate interest or penalty clauses and may extend cooling-off periods. Consumer-lending teams should prepare for an increase in post-signing queries and potential rescission requests during any new cooling-off window.

A practical compliance checklist for consumer credit teams should include verification that all affordability models are documented and auditable, that disclosure templates incorporate the new Civil Code requirements, and that customer-facing staff are trained on the borrower’s expanded rights.

Litigation and Regulatory Risk, What Credit Teams Must Anticipate

The transition period around any loan reform in Belgium invariably produces litigation. Early indications suggest three primary risk areas. First, guarantors may challenge the enforceability of pre-reform guarantees on the basis that mandatory disclosure requirements were not met. Second, borrowers in financial difficulty may invoke the new hardship and renegotiation provisions to delay or resist enforcement proceedings. Third, regulatory supervisors, notably the FSMA and the National Bank of Belgium, are expected to issue guidance on how the new rules interact with existing prudential and conduct-of-business requirements, and banks that have not aligned their processes may face supervisory action.

Recommended mitigation steps include comprehensive document-retention policies that capture all pre-contractual disclosures and affordability assessments, periodic internal audits of compliance with the new formality requirements, and the establishment of a rapid-response protocol for any regulatory inquiry related to the reforms.

Implementation Checklist and Governance

Effective implementation requires clear governance. The following checklist assigns ownership and milestones across the four key functions.

• Legal: Complete clause-by-clause review of all template agreements; deliver updated templates to Documentation team. Milestone: 45 days. KPI: 100% of templates reviewed.
• Compliance: Finalise and deploy updated disclosure notices; conduct gap analysis on consumer-affordability procedures. Milestone: 60 days. KPI: Zero product launches without compliant disclosures.
• Credit / Operations: Recalibrate affordability models; update servicing systems for new notice periods and guarantor-information triggers. Milestone: 75 days. KPI: System-readiness sign-off.
• IT: Update document-management systems to store guarantor information notices, affordability records and disclosure logs in an auditable format. Milestone: 90 days. KPI: Audit-trail functionality live.

An executive sponsor, ideally the Chief Risk Officer or General Counsel, should chair a fortnightly steering committee until the final law is published and full compliance is confirmed.

Conclusion, Acting Now on the Loan Reform in Belgium

The 2026 civil code loan reform represents the most significant overhaul of Belgian lending law in a generation. With the personal-security rules already live and the loan-rules consultation draft now published, the window for proactive compliance is open but narrowing. Banks that treat this as a documentation exercise alone will underestimate the reform’s reach, it touches origination, servicing, enforcement and litigation strategy in equal measure. Legal teams across Belgium should begin their template audits, disclosure updates and enforcement-playbook revisions immediately, well ahead of the final legislative text.
