People assume a will controls what happens to everything they own. Several of the largest assets most Americans hold pass outside it, by a form signed years earlier.
Some assets transfer by contract, not by estate
Retirement accounts, life insurance policies and certain bank and brokerage accounts allow the owner to name a beneficiary who receives the asset on death.
These transfers occur by the terms of the account agreement. The asset does not enter the probate estate, and instructions in a will generally do not reach it.
The practical result is that a form completed during onboarding at a job long past can direct more money than the will drafted afterwards.
Life events do not update the forms
Marriage, divorce, births and deaths change intentions but do not change designations. Nothing in the process prompts a review unless the account holder initiates it.
Divorce settlements sometimes address these assets, but the agreement and the actual designation are separate documents, and only one controls the payout.
Some state laws automatically revoke certain designations on divorce, though the effect varies and can be limited where federal rules govern the account type.
Naming a minor or an estate creates complications
Minor children generally cannot receive assets directly, so a designation naming them can trigger court-supervised arrangements that the parent did not intend.
Naming the estate as beneficiary pulls the asset into probate, which removes the speed and privacy advantages of a direct designation and can change tax treatment.
Trusts are sometimes used instead, but the drafting has to be correct, because rules governing retirement accounts payable to trusts are technical.
Contingent beneficiaries are frequently left blank
Most forms allow a primary and a contingent beneficiary. Only the primary line tends to be completed, which leaves no instruction if the primary dies first.
When that happens the account defaults to the plan's own rules, which may direct the asset to the estate or to a hierarchy of relatives.
Completing the contingent line costs nothing and removes an outcome that is otherwise decided by default terms nobody read.
Review is a periodic administrative task
Designations should be checked with each provider directly, since employers change record keepers and old confirmations may not reflect the current file.
Old employer plans left in place after a job change are the most commonly overlooked accounts, particularly small balances from early in a career.
Because rules differ by account type and by state, and change over time, an estate planning attorney is the appropriate professional for anything beyond routine updates.
