Impecuniosity Explained
Impecuniosity means the claimant could not reasonably have laid out the cost of hiring a replacement vehicle from their own resources, which entitles them to recover the full credit hire rate rather than the basic hire rate. It is the single most consequential issue in a credit hire claim: get it wrong and the claim collapses to basic hire rate, often a fraction of the schedule.
This guide explains the impecuniosity test, the Pattni eight-principle framework, the Hussain v EUI disclosure standard, and the post-Umerji burden of proof, with the practical disclosure list every handler should be working from.
The Lagden test
The leading authority is the House of Lords decision in Lagden v O\'Connor [2003] UKHL 64. Lord Nicholls held that where a claimant\'s impecuniosity prevented them from mitigating their loss by hiring on the open market, they were entitled to recover the additional cost of credit hire. The test is whether the claimant could have paid mainstream hire charges without making sacrifices they could not reasonably be expected to make.
The Pattni eight-principle framework
Pattni v First Leicester Buses Ltd [2011] EWCA Civ 1384 structured the Lagden test into eight practical principles. In summary the court looks at:
- The claimant\'s income and regular outgoings at the date of hire.
- Savings and other readily-available funds.
- Available credit (cards, overdraft, family loans).
- Essential household commitments and dependants.
- The realistic cost of mainstream hire and any deposit / pre-authorisation requirement.
- Whether using available credit would have required unreasonable sacrifices.
- The claimant\'s actual financial conduct in the relevant period.
- The whole picture, not any single factor.
The framework is fact-sensitive. A claimant with a £5,000 credit limit and £4,800 already owed is not in the same position as one with the same limit and a zero balance. The court asks what would have been required, in the real world, on the date of hire.
The Hussain disclosure standard
Hussain v EUI Ltd [2019] EWHC 2647 (QB) sharpened the evidential burden. The High Court held that the impecuniosity case must be properly pleaded and properly evidenced. The current practical disclosure expectation is at least three months of bank statements, credit card statements, payslips, and evidence of any available credit, covering the period either side of hire. A bare assertion of impecuniosity, unsupported by documents, will not succeed.
Burden of proof, Zurich v Umerji
Zurich Insurance Plc v Umerji [2023] EWCA Civ 357 confirmed two important points. First, the burden of proving impecuniosity lies squarely on the claimant, the claimant must plead and prove it. Second, impecuniosity is relevant to both the rate of hire and the period of hire. An impecunious claimant who could not promptly fund a replacement vehicle is entitled to a longer recoverable hire window.
Practical disclosure list
For a defensible impecuniosity case, expect to disclose:
- Three months of bank statements covering all current accounts.
- Credit and store card statements for the same period.
- Payslips covering the same period (and tax returns for the self-employed).
- Evidence of any available credit facility (overdraft, loan, credit limit).
- Council tax, rent or mortgage statements where relevant to essential outgoings.
- Witness evidence from the claimant addressing the Pattni principles directly.
Common defence attacks
- Available credit. The insurer points to a credit card with headroom and says the claimant could have hired on it. The Pattni response is that headroom alone does not equal availability, interest, sacrifice and ordinary use all matter.
- Snapshot accounts. The insurer focuses on a high closing balance on a single day. The response is the realistic picture across the three-month window, not a single snapshot.
- Household pooling. The insurer argues the claimant could have used a partner\'s funds. The response is that the claimant\'s own resources are the test, not those of the wider household.
- Pleading deficiency. The insurer says impecuniosity is not properly pleaded. Following Umerji this is a real risk, plead the Pattni principles expressly.
How CreditHire Assist helps
The Impecuniosity Assessment tool works through the Pattni eight-principle framework against the claimant\'s actual bank statements, identifying strengths, gaps and the disclosure required to meet the Hussain standard. The TPI Correspondence Analyzer flags Pattni-shaped defences in insurer letters and routes the reply through verified authority. Every cited case is in the verified case law database.
