Underwriting year

For accounting and classification purposes it is the treaty year in which a contract was written or renewed. Applies to proportional reinsurance. See UNDERWRITING YEAR SYSTEM.
***
The calendar year during which the risk attaches on the original Insurance.
***
the accounting year of an insurer or Lloyd’s syndicate to which insurance business relates, usually determined by the date of inception; reinsurance contracts may be written by reference to the insurer’s business of a particular underwriting year, and will remain in force until all the claims referable to that underwriting have been settled.

Unearned Premium Insurance

See: Aviation Unearned Premium INSURANCE.
***
Insurance against loss by the insured of unearned premium due to payment of a claim made prior to the end of the term for which the premium was paid. A loss on the second day of a Policy written for a year would have the effect of being expenses over an eleven month period, during which time the Insurance Company would not be insuring the risks since the risk did not exist any longer and thus it would be unearned.

Unenforceable contract

A contract defective only in the sense that it cannot be enforced by direct legal action. The contract is otherwise valid and subsisting, so a transferee of property gains a good title and any deposit paid may be retained. A contract of fidelity guarantee not in writing would be unenforceable (the Statute of Frauds).
***
This is one, which lacks some evidential features. The contract is a valid one otherwise, but could not be enforced in a court of law.

Unfair Contract Terms Act 1977

Governs a trader’s ability to restrict his liability. Any clause restricting negligence liability for death/injury is void. The following clauses will be void unless reasonable. (a) those attempting to restrict negligence liability for loss or damage to property; (b) standard term clauses limiting liability for breach contract; (iii) those requiring a consumer to indemnify any other party for negligence or breach of contract. It also provides that a trader cannot exclude a consumer’s statutory rights under the Sale of Goods Act 1979. The Act lays down a test of reasonableness. Insurance policies are exempt from the Act.
