York Antwerp Rules
- 1. The onus of proof is upon the party claiming in general average to show that the loss or expense claimed is properly allowable as general average.
- 2. All parties to the common maritime adventure shall, as soon as possible, supply particulars of value in respect of their contributory interest and, if claiming in general average, shall give notice in writing to the average adjuster of the loss or expense in respect of which they claim contribution, and supply evidence in support thereof.
- 3. Failing notification, or if any party does not supply particulars in support of a notified claim, within 12 months of the termination of the common maritime adventure or payment of the expense, the average adjuster shall be at liberty to estimate the extent of the allowance on the basis of the information available to the adjuster. Particulars of value shall be provided within 12 months of the termination of the common maritime adventure, failing which the average adjuster shall be at liberty to estimate the contributory value on the same basis. Such estimates shall be communicated to the party in question in writing. Estimates may only be challenged within two months of receipt of the communication and only on the grounds that they are manifestly incorrect.
- 4. Any party to the common maritime adventure pursuing a recovery from a third party in respect of sacrifice or expenditure claimed in general average, shall so advise the average adjuster and, in the event that a recovery is achieved, shall supply to the average adjuster full particulars of the recovery within two months of receipt of the recovery.
