Explanation of the pari passu principle in UK insolvency law, including how equal distribution works among unsecured creditors, statutory rules under the Insolvency Act 1986, exceptions, case law principles, and how insolvency estates are distributed in liquidation proceedings.

The pari passu principle is a fundamental rule in insolvency law in England and Wales that ensures unsecured creditors are treated equally when a company's assets are distributed during insolvency. The term “pari passu” comes from Latin, meaning “on equal footing”.
In practical terms, it means that creditors within the same class must share in the available assets proportionally, rather than being paid in full while others receive nothing. This principle is central to fairness in liquidation and applies primarily to unsecured creditors under the Insolvency Act 1986 and related insolvency rules.
Legal Basis of the Pari Passu Principle
The pari passu principle is not a single statutory provision but a core doctrine embedded throughout UK insolvency law. It operates alongside:
- Insolvency Act 1986
- Insolvency (England and Wales) Rules 2016
- Established case law on insolvency distribution
- Principles governing creditor claims in liquidation and administration
It applies most clearly where assets are insufficient to pay all creditors in full, requiring a structured and proportional distribution.
Meaning of Pari Passu in Insolvency Law
In insolvency distribution, pari passu means:
Creditors of the same class are paid equally in proportion to the size of their admitted claims.
This does not mean every creditor receives the same amount in cash. Instead, each creditor receives the same percentage of their debt.
For example:
- Total unsecured debts: £1,000,000
- Available funds: £200,000
- Dividend: 20p in the pound
A creditor owed £10,000 would receive £2,000, while a creditor owed £100,000 would receive £20,000.
How the Pari Passu Principle Works in Practice
1. Identification of creditor classes
Before distribution, creditors are grouped into legally defined categories:
- Secured creditors (fixed charge)
- Secured creditors (floating charge)
- Preferential creditors
- Unsecured creditors
Pari passu applies primarily within the unsecured creditor class, not across all categories.
2. Assessment of admitted claims
The insolvency practitioner reviews claims submitted by creditors, known as proofs of debt, and determines:
- Whether the debt is valid
- The correct amount owed
- Any set-off rights or adjustments
Only admitted claims participate in pari passu distribution.
3. Asset realisation
The liquidator or administrator converts company assets into cash, forming the distributable estate.
After deducting:
- Insolvency costs
- Secured creditor payments
- Preferential claims
the remaining funds are allocated to unsecured creditors on a pari passu basis.
4. Proportional distribution
Each unsecured creditor receives the same percentage of their proven debt, ensuring equality within the class.
Legal Purpose of the Pari Passu Principle
The principle exists to ensure:
1. Fairness among creditors
No unsecured creditor is unfairly prioritised over another within the same class.
2. Orderly insolvency process
Without pari passu, creditors would compete individually for assets, leading to disorder and unequal outcomes.
3. Predictability in insolvency law
Creditors and lenders can assess risk knowing they will be treated equally within their class.
4. Protection against preferential treatment
It prevents directors or insolvency practitioners from selectively paying certain unsecured creditors.
Exceptions to the Pari Passu Principle
Although central to insolvency law, the principle is not absolute.
1. Secured creditors
Secured creditors are paid outside pari passu rules from their security interests.
2. Preferential creditors
Statute gives certain creditors priority over others (e.g. employee wage claims).
3. Set-off rules
Mutual debts between a company and creditor may be offset before distribution.
4. Statutory charges and prescribed part
The “prescribed part” mechanism diverts a portion of floating charge assets to unsecured creditors, slightly modifying strict distribution outcomes.
Case Law Supporting the Principle
UK courts have consistently upheld pari passu distribution as a cornerstone of insolvency law. Key judicial reasoning emphasises:
- Equal treatment of creditors within classes
- Prevention of private agreements that undermine collective insolvency outcomes
- Strict adherence to statutory priority rules
While the principle is rarely disputed, litigation often arises when creditors attempt to circumvent it through security arrangements or preferential payments.
Pari Passu in Liquidation vs Administration
In liquidation
The principle is most strictly applied. All available assets are distributed according to statutory order and equal treatment within creditor classes.
In administration
Pari passu still applies, but the administrator may prioritise achieving a better overall outcome, such as selling the business as a going concern. This can indirectly affect distributions, but equality within creditor classes remains a guiding rule.
Practical Examples of Pari Passu Distribution
Example 1: Simple unsecured distribution
- Total unsecured claims: £500,000
- Available funds: £100,000
- Dividend: 20p in the pound
All creditors receive 20% of their claim.
Example 2: Mixed creditor classes
- Secured creditor: £200,000 (paid from security)
- Preferential creditors: £50,000 (paid in full)
- Remaining unsecured pool: £100,000
- Unsecured claims: £400,000
Unsecured creditors receive 25p in the pound under pari passu.
Common Issues in Pari Passu Distribution
1. Disputed claims
If a claim is rejected or reduced, it changes the distribution ratio for all unsecured creditors.
2. Late claims
Late submissions may still be admitted but can delay final distribution.
3. Insolvency costs
Higher-than-expected costs reduce the funds available for pari passu distribution.
4. Fraudulent or preferential payments
Recovering unfair pre-insolvency payments can increase the pool for distribution.
Legal and Commercial Significance
The pari passu principle underpins creditor confidence in lending and commercial transactions. It ensures:
- Transparent insolvency outcomes
- Reduced risk of unfair insider advantage
- Stability in credit markets
- Predictable recovery expectations for unsecured creditors
Without it, unsecured lending would carry significantly higher risk and cost.
Key Takeaways
The pari passu principle in insolvency distribution ensures that unsecured creditors are treated equally and receive a proportional share of available assets based on their admitted claims. Rooted in UK insolvency law and supported by long-standing legal principles, it operates primarily after secured and preferential claims have been satisfied. While there are statutory and structural exceptions, it remains a central rule that guarantees fairness, transparency, and predictability in insolvency proceedings.
