Block Buster Will Law and Legal Definition

Block Buster Will refers to a testamentary instrument that overrides beneficiary designations in non-probate instruments such as life insurance policies, retirement plans, and bank accounts. The expression "block buster will" was coined by estate planners in the mid-70's to signal interest in legislation enabling a later will to override death benefits by any nonprobate transfer device. Most states do not authorize block buster wills.
