ABSTRACT

Beneficiary designations and Wills operate through different transfer mechanisms. The American Bar Association explains that assets passing by beneficiary designation are generally non-probate assets unless the estate is named as beneficiary, and that non-probate assets pass outside the Will’s terms. Life insurance, retirement accounts, payable-on-death accounts, and transfer-on-death registrations are common examples of assets that may use beneficiary designations. A Will generally directs probate property. This means consistency across the Will, account designations, and ownership structure matters. The result for a specific asset depends on the account contract, the beneficiary form, state and federal law, and any special rules that apply to spouses, retirement plans, or other property.

Question presented

If a Will names one beneficiary but an account names another, which instruction controls?

Summary of findings

The answer generally depends on the legal mechanism governing the asset. Assets with valid beneficiary designations commonly pass outside probate according to the designation, while the Will governs probate property. That makes beneficiary forms part of the estate plan even though they are maintained outside the Will.

Analysis

Beneficiary-designated assets are commonly non-probate assets

The American Bar Association notes that assets transferred by beneficiary designation are generally non-probate assets unless the estate itself is named as beneficiary. Common examples include retirement plans, life insurance, and certain financial accounts.

The Will governs a different pool of property

A Will generally directs property that becomes part of the probate estate. If an asset already has an effective transfer mechanism outside probate, the Will may not control that asset.

Why conflicts happen

Beneficiary forms are often completed years before a Will is updated. Marriage, divorce, births, deaths, account rollovers, and changes in family relationships can leave old designations in place. A current Will does not necessarily cure an outdated beneficiary form.

Primary and contingent beneficiaries

Many accounts allow an owner to name a primary beneficiary and one or more contingent beneficiaries. The exact effect of a beneficiary’s death, disclaimer, or ineligibility depends on the account terms and applicable law.

Federal rules can matter

Some retirement plans and employee benefits are governed in part by federal law, which can affect spousal rights and beneficiary procedures. This is one reason a national article should not provide a one-size-fits-all answer for every account.

Where the answer varies

The controlling rules can depend on the account type, plan document, beneficiary form, marital status, federal law, and state law. Divorce and remarriage can create additional complexity.

Steward context

Steward treats beneficiary designations as a separate but important part of family planning. A Will does not automatically rewrite beneficiary forms maintained by an insurer, retirement plan, bank, or brokerage. If you are trying to resolve a conflict between a Will and a beneficiary designation, you should consult a licensed attorney in your state.
