Beneficiary changes in insurance contracts generally become effective once the insurer receives and processes the signed change form. This is supported by LLQP material, which specifies that changes to beneficiary designations must be documented and received by the insurer for the new designation to take effect.

Option B is incorrect as revocable beneficiaries do not require consent for changes. Option C is too general, and D is incorrect because a formal written change form is typically required.
