Anti-assignment clauses are insurance policy provisions that require the insurance company's consent to any assignment or transfer of rights of the policy and are generally enforceable before a loss occurs.
The assignment of rights before a loss occurs basically becomes a transfer of a contractual relationship, which is generally discouraged by the courts and prohibited by this anti-assignment clause. If the assignment occurs after a loss, the majority rule is that the anti-assignment clause is void and unenforceable.
