Before accepting a personal or corporate guarantee offered by a local debtor in a supply or trade-credit context, a creditor needs to verify three independent facts: that the guarantor legally exists and is authorised to give guarantees. that no insolvency. Enforcement. Alternatively, tax-execution proceeding is already running against them. and that the assets or income cited in the guarantee actually cover the exposure. None of these facts can be confirmed from a single register – each requires a distinct source, a specific extraction method, and an honest assessment of what that source does and does not reveal. This page maps the standard sequence of checks, the registries consulted at each step, their known limitations, and the categories of risk that remain structurally unverifiable regardless of how thorough the search is.
Why a guarantee check differs from a standard credit check
A credit check typically asks: "Will this counterpart pay on time?" A guarantee check asks something narrower and more forensic: "If the primary debtor fails. Will calling on this guarantee actually produce recovery?" The two questions require different evidence. A company might have excellent trading credit. prompt invoices, low days-sales-outstanding. while simultaneously having pledged all its fixed assets to a bank. Registered a subordination agreement that delays recovery. Alternatively, posted a personal guarantee in favour of a different creditor that ranks ahead of yours.
The supply-risk dimension adds a further layer. In supply-chain financing structures, the guarantor is frequently a director, majority shareholder, or related holding entity of the buyer. The moment the buyer fails, the guarantor's own liquidity is typically impaired by the same shock – falling receivables, frozen credit lines, or cross-default clauses triggered in their own loan agreements. Evaluating a guarantee purely on the guarantor's historical financial statements, without checking current encumbrances and proceedings, therefore understates the real risk in precisely the moment the guarantee would be called.
Step 1 – Legal existence and authority to give guarantees
What you are checking. A guarantee given by an entity that does not legally exist, is dormant, has been struck off, or whose representative lacked authority at the time of signing may be wholly unenforceable. This step is non-negotiable and must be completed before anything else.
Commercial and company registries. The primary source is the commercial registry of the jurisdiction where the guarantor is incorporated or domiciled. In Portugal, this is the Registo Comercial, accessible through the portal of the Instituto dos Registos e do Notariado. Most EU member states maintain analogous registers; many participate in the Business Registers Interconnection System (BRIS), which allows cross-border basic searches at the European level. For entities in common-law jurisdictions, Companies House (UK), the SEC's EDGAR database (US listed entities), or equivalent national registries serve the same function.
What the registry reveals. A current certificate of registration (certidão permanente or its equivalent) shows: legal name, registered number, date of incorporation. Registered address, current status (active/dissolved/in liquidation), registered share capital. Additionally, the identity and powers of current registered directors or administrators. Critically, it shows whether the articles of association restrict the company's capacity to give guarantees – a frequent limitation in holding entities and family vehicles.
What the registry does not reveal. The registry does not show whether the company is trading actively. A company may be legally active – no dissolution registered – while having zero employees, no contracts, and no income. It does not show bearer shareholdings where these still exist under legacy structures in certain jurisdictions. It does not automatically flag shareholder agreements, side letters, or usufruct arrangements over shares that might affect control. And in most jurisdictions, there is a registration lag: a change of director resolved today may not appear in the public register for days or weeks.
Powers and authority. Beyond existence, you must verify that the specific individual who signed the guarantee document was duly authorised at the moment of signing. This means checking the registered powers of attorney, the articles governing signature authority (joint vs. sole signature), and any board resolution required by the articles for guarantee transactions above a certain threshold. Guarantees signed without the required board approval are voidable in most civil-law systems and may be void in common-law jurisdictions depending on the doctrine of actual vs. apparent authority.
Step 2 – Insolvency, enforcement, and tax-execution proceedings
Why this step cannot be skipped. A guarantor subject to an ongoing insolvency proceeding cannot as a rule give new guarantees that bind the estate. and any guarantee already given may be subject to avoidance actions if it was granted during the suspect period preceding insolvency (the período suspeito in Portuguese law. Equivalent to the fraudulent-preference or preference-payment windows in other jurisdictions). Even outside formal insolvency, an active tax-execution order or enforcement proceeding against the guarantor's assets may have already effectively encumbered the assets you intend to rely on.
Insolvency registries. In Portugal, insolvency proceedings are registered in the Registo Predial (for real property effects), published in the Diário da República, and visible through the Citius platform maintained by the Ministério da Justiça. The Citius portal allows public searches for published insolvency and restructuring proceedings. In other EU jurisdictions, insolvency proceedings above a certain threshold are required to be published in the national insolvency register (e.g.. The Insolvenzbekanntmachungen in Germany, the Bodacc in France, the Gazette in Ireland and the UK). For cross-border cases, the European Insolvency Register aggregates published proceedings across member states.
Tax-execution registers. Tax authorities in most jurisdictions maintain internal enforcement registers that are not publicly searchable in real time. In Portugal, the Autoridade Tributária e Aduaneira (AT) issues tax clearance certificates (certidões de não dívida) upon request by the taxpayer or, in certain circumstances, by third parties with a legitimate interest. A clean certidão confirms no registered tax debt as of the date of issue. but it is a snapshot, not a guarantee of the future. Additionally. The AT's internal enforcement register is not accessible to third-party creditors without a court order or the taxpayer's own disclosure.
Civil enforcement actions. Ongoing civil enforcement (execução civil) against the guarantor is visible through court records, but in Portugal and most EU systems these are not consolidated in a single searchable index. A lawyer with standing can request certificates from individual courts. Additionally, certain automation tools aggregate published enforcement notices. However. Complete coverage is not achievable without knowing which courts have territorial jurisdiction over the debtor's assets. which itself requires knowing where those assets are located.
Practical limitation. There is no single register – in Portugal or in most jurisdictions – that consolidates insolvency proceedings, tax-execution orders, and civil enforcement actions in real time. A report based on registry searches captures what has been formally registered as of the search date. it does not capture proceedings initiated but not yet registered. Alternatively. Enforcement initiated in jurisdictions not covered by the search.
Step 3 – Asset encumbrances and collateral registers
The core question. Even a solvent, unencumbered guarantor is only as valuable as the assets they actually own and that are not already pledged to other creditors. This step maps what is registered against the guarantor's known assets.
Real property register. In Portugal, the Registo Predial (land registry) is the authoritative source for mortgages (hipotecas), charges, easements, and other encumbrances over real property. A certidão de teor obtained from the land registry office for each registered property shows all entries in order of registration, with the identity of the beneficiary creditor, the secured amount, and the rank. Portuguese law operates a priority-by-registration system: a later-registered mortgage is junior to an earlier one regardless of when the underlying loan was made. For guarantors in other jurisdictions, equivalent searches must be run in the applicable property register.
Movable property and financial collateral. In Portugal, charges over movable assets, inventory, receivables. Additionally. Financial instruments are registered in different registers depending on asset type: the Registo Automóvel for vehicles. the Registo de Aeronaves Civis for aircraft. and various sectoral registers for specific asset classes. Portugal has not yet adopted a unified personal property security register of the type that exists in common-law jurisdictions (such as the PPSR in Australia and New Zealand. Alternatively. The register under Article 9 of the UCC in the United States). This means that charges over receivables, stock, or trade assets may be registered in ways that are harder to aggregate in a single search.
Pledges and financial collateral arrangements. Financial collateral arrangements over securities accounts and cash are governed in Portugal by Decree-Law 105/2004 (implementing Directive 2002/47/EC) and do not require public registration to be valid between parties. they are perfected by possession or control, not registration. This is a significant blind spot: a guarantor may have pledged its entire securities portfolio to a bank under a financial collateral agreement that is legally effective but does not appear in any public register.
Corporate charges and share pledges. A pledge over shares in a Portuguese limitada (LDA) must be registered in the commercial registry to be effective against third parties. A pledge over shares in a sociedade anónima (SA) held in book-entry form is registered with the central securities depository (Interbolsa), which is not publicly searchable. Pledges over shares in foreign entities are governed by the law of the place of incorporation and may or may not appear in a public register.
Step 4 – Guarantor's own guarantee obligations and contingent liabilities
What the registers do not show. A guarantor who has already guaranteed the obligations of five other companies. each potentially in difficulty. carries contingent liabilities that do not appear in any of the registers described above unless those guarantees have already been called and enforcement commenced. Reviewing the guarantor's published accounts (if they have a filing obligation) for notes on contingent liabilities, off-balance-sheet commitments, and related-party transactions is an essential supplement to registry searches.
Published accounts. In Portugal, companies above certain size thresholds are required to file annual accounts (contas anuais) with the Registo Comercial, and these are publicly accessible. Small companies may file abbreviated accounts that do not include notes. Sole traders and certain partnership vehicles have no accounts-filing obligation at all. Where accounts exist, they should be reviewed for at least three years to assess trends in leverage, working capital, and the notes on contingent liabilities. Where accounts are absent or more than twelve months old, the information gap must be explicitly flagged in the report.
Cross-guarantees and group structures. In supply-chain contexts, guarantors that are holding companies or group entities are particularly prone to cross-guarantee webs that are invisible from any single source. Mapping the corporate group structure – through commercial registry extracts for each related entity – and identifying intra-group loan agreements and guarantees requires lateral investigation beyond the guarantor's own registry record.
Step 5 – Sanctions, PEP status, and reputational screening
Why it matters for enforceability. A guarantee given by a sanctioned person or entity may be unenforceable or may expose the beneficiary to regulatory liability for receiving the guarantee proceeds. Similarly, a guarantor who is a politically exposed person (PEP) triggers enhanced due diligence obligations under the EU Anti-Money Laundering Directives, regardless of whether the transaction is structured as a guarantee or a direct payment.
Sanctions registers. The EU Consolidated Sanctions List, the UN Security Council Consolidated List, and the OFAC Specially Designated Nationals list (for USD-clearing or US-nexus transactions) are the primary public sources. These registers are publicly searchable and are updated in near-real time when designations change. Screening should cover not only the guarantor's legal name but also any known aliases, beneficial owners above the applicable threshold (25% in the EU AML framework), and controlling persons.
PEP and adverse media screening. There is no single public PEP register. PEP status is established by checking official government sources (published lists of current and former officeholders), commercial PEP databases, and structured adverse media searches. The absence of a hit on a PEP database is not conclusive – a recently appointed official may not yet appear in commercial databases.
What remains structurally unverifiable
Even a thorough, multi-source debtor report leaves a defined category of facts that cannot be confirmed through publicly available registers:
Undisclosed encumbrances. Financial collateral arrangements, certain types of title-retention clauses. Additionally. Factoring or securitisation arrangements over receivables do not require public registration in Portugal or in most EU jurisdictions to be effective between the parties and, in some cases, against third parties. A guarantor may have effectively transferred economic ownership of its most liquid assets without any public trace.
Informal undertakings and side letters. A guarantor may have given informal comfort letters, keep-well agreements, or side undertakings to other creditors that are contractually binding but are not registered anywhere. These are only discoverable through direct disclosure – which requires the guarantor's cooperation – or through litigation discovery.
Recent transactions in the suspect period. Transactions completed before the search but not yet registered. Alternatively. Transactions that will later be challenged as avoidance actions if insolvency follows, are not visible in the register at the time of the search. The suspect period under Portuguese insolvency law (CIRE) reaches back up to two years for certain transactions with connected parties.
Future events. No register reflects what will happen after the search date. A company that is clean today may have entered administration tomorrow. Tax-clearance certificates are valid only as of the date of issue. The report describes a snapshot; the gap between the snapshot and the date the guarantee is actually called may be months or years.
Recommended sequence and timing
The checks described above should be run in the following recommended order, which balances efficiency against the risk of discovering a fatal defect late in the process:
1 – Legal existence and authority (commercial registry extract): this is a binary pass/fail. If the guarantor does not exist or the signatory lacked authority, no further checks are necessary and the guarantee structure must be redesigned before proceeding.
2 – Insolvency and enforcement searches: the second gate. An ongoing insolvency proceeding makes the guarantee either void, voidable, or commercially worthless. This check should be completed before investing time in detailed asset mapping.
3 – Sanctions and PEP screening: a regulatory compliance gate. A positive hit may require external counsel advice before the transaction can proceed at all.
4 – Asset encumbrance searches (real property register, movable-asset registers. Commercial registry for share pledges): this is the most time-consuming step and should be scoped to the assets the guarantor has represented as backing the guarantee.
5 – Review of published accounts and contingent liabilities: analytical layer over the registry data. Fills in the picture on leverage, covenant status, and disclosed contingent exposures.
6 – Gap assessment: explicit documentation of what the searches did not cover, what the guarantor has not disclosed, and what structural blind spots remain. This is not an optional final note – it is a core deliverable of the report, because it defines the residual risk the creditor is accepting.
All searches should be completed as close as possible to the date of execution of the guarantee, not the date of the initial commercial negotiation. In active enforcement markets, the position of a guarantor can change materially in a matter of weeks.

When a report is not enough
A debtor report is an evidentiary exercise: it gathers and organises publicly available information so that you can make an informed decision about accepting a guarantee. It is not a substitute for legal structuring of the guarantee itself. If the report reveals material encumbrances, a questionable authority chain. Alternatively, a high ratio of contingent liabilities to assets, the appropriate response is not to proceed and document the risk. it is to restructure the guarantee. Require additional collateral, negotiate a first-demand bank guarantee or insurance-backed instrument. Alternatively, reduce the credit exposure to a level consistent with what the report confirms is unencumbered.
The report is most useful when it is commissioned early in the commercial negotiation, before the counterpart has been told which assets you expect to be backed by the guarantee. Commissioning it after term sheets are signed and counterpart expectations are set creates commercial pressure to proceed despite findings that would justify renegotiation.
For matters where the report findings need to be translated into legal structuring advice. drafting guarantee clauses, advising on ranking and subordination. Alternatively. Advising on enforcement strategy if the guarantee is later disputed. our Banking &. Finance and Litigation teams are available to provide a coordinated mandate.
