Assignment CASES

In English law, assignment refers to transferring rights or benefits under a contract from one party (the assignor) to another (the assignee).

Definition and Principles

Assignment allows contractual rights, such as payment or benefits, to be transferred without altering original contractual obligations. Generally, obligations (duties) themselves cannot be assigned without the other party’s consent.

Prohibition on Assignment

Contracts may expressly prohibit or restrict assignment. A valid prohibition on assignment clause prevents parties from assigning rights to third parties, maintaining contractual control and certainty.

Common Examples

  • Assigning debts to a debt-collection agency.
  • Transferring rights to receive payment under commercial agreements.
  • Clauses prohibiting assignment in commercial leases, insurance contracts, or personal services contracts.

Legal Implications

  • An assignment generally requires notice to the debtor to become effective.
  • Breach of a prohibition on assignment clause may invalidate the transfer or give rise to claims for damages.

Practical Importance

Understanding assignment ensures clarity on rights transfers, helps manage contractual risks, and highlights the significance of explicitly addressing assignment within contracts.
