Can I screen an international tenant against multiple country watchlists?

Question

Accepted Answer

Yes. Every Certaby letting-agent check runs against four catalogues simultaneously: the OFSI consolidated UK list, the UN Security Council Consolidated List, the EU Consolidated List of Financial Sanctions, plus the OpenSanctions global Match catalogue (which spans 40+ national sanctions lists, the FATF politically-exposed-persons catalogue, and adverse-media collections). For an international tenant the screen is structurally already global; the difference is whether the cert names the jurisdictions explicitly.

When the cert needs to name specific jurisdictions for the audit trail (HMRC inspection, MLRO sign-off, regulator request), pass an explicit list on the request:

```
POST /v1/suites/letting-agent/check
{
  "tenant": { "kind": "individual", "fullName": "Jane Doe", "nationality": "IE" },
  "landlord": { ... },
  "property": { ... },
  "screenJurisdictions": ["GB", "IE", "US", "EU"]
}
```

The response carries the same array in `result.screenJurisdictions` so the customer's audit trail records exactly which jurisdictions were screened, not just an implicit global default. Default behaviour (when the field is omitted) records `['GB']` only, which is correct for UK-only lets.

Why this matters for letting agents under LSAG-2025: an HMRC inspection can ask about the screen depth on a specific high-risk let. Naming the jurisdictions on the cert pre-empts the question. SmartSearch + Veriphy claim 40+ countries via opaque enterprise sanctions feeds; the Certaby + Stratum stack achieves the same coverage via OpenSanctions per-call retail + transparent cert provenance, at £4.95 per check rather than annual contract pricing.

Technical note (T1.7 v1): the field is metadata-only on the response shape today; PDF rendering of the jurisdictions list on the cert cover lands in a follow-up iter (would require a SCHEMA_VERSION bump on the hash binding). Until then the audit-trail evidence sits in the JSON response that customers persist alongside the PDF.
