The estate attorney sent the amended trust document in the spring. The client reviewed it, signed it, and filed it. The trust now reflected the correct structure: a generation-skipping provision for the grandchildren, a separate share for the surviving spouse, and a charitable remainder for the foundation the client had decided to support.
The $1.4 million IRA still named the client’s ex-spouse as primary beneficiary. That form hadn’t been touched in eleven years.
The trust said what the client intended. The beneficiary designation said what happened.
Two documents, one winner
A beneficiary designation is a separate legal document from a will or trust. It is the form on file at the account custodian: the life insurance company, the IRA administrator, the 401(k) plan. When the account holder dies, the account goes to whoever is named on that form. Period. The will does not override it. The trust does not override it. The estate attorney’s most carefully drafted language does not override it.
This is not a loophole or a technicality. It is how the law works for assets that pass outside probate. Life insurance, IRAs, 401(k)s, annuities, and certain bank and brokerage accounts all transfer directly to the named beneficiary without going through the estate at all. The trust never sees them.
The consequence of this structure: if the trust says one thing and the beneficiary designation says another, the designation controls. Every time.
When the trust gets updated and the designations don’t
The most common version of this problem is the one-way update. The client works with the estate attorney to revise the trust: adding provisions for minor grandchildren, removing a spouse after a divorce, adjusting distribution timing, incorporating a new charitable intent. The attorney drafts the amendment. The client signs. The trust is current.
The beneficiary designations on the client’s IRA, 401(k), and life insurance policy were last updated when the accounts were opened. The estate attorney cannot update them. Those changes require a separate form, submitted to a separate institution, that has no connection to the attorney’s file.
Nobody sends a notification to the IRA custodian when the trust changes. Nobody at the insurance company knows that the trust amendment happened. The form on file is the one the client submitted years ago, when the accounts were opened or when the last major life event prompted an update.
Most clients assume that updating the trust updates the plan. It does not. The trust and the beneficiary designations are maintained by different institutions, and they do not communicate with each other.
The specific mismatches
The most serious mismatch is a named individual who should no longer receive the asset: a former spouse, a deceased parent, an estranged sibling who was named in a moment that no longer reflects the client’s wishes. The designation controls, regardless of what the trust says.
A second mismatch is a missing generation-skipping provision. If the trust was updated to pass assets to grandchildren in a tax-efficient structure, but the IRA designation names the client’s children as direct beneficiaries, the IRA bypasses the structure. The generation-skipping intent fails.
A third mismatch involves a trust that was named as beneficiary on an older account, where the trust itself has since been amended or replaced. The account now funds an outdated trust structure, not the current one. The distribution mechanics from the older trust govern, even though the client no longer uses that document.
The review that closes the gap
Closing this gap requires comparing two sets of documents: the current trust and each account’s beneficiary designation form. Most clients have never done this comparison because the information lives with different institutions.
The estate attorney has the trust. The IRA custodian has the designation form. The insurance company has its own. The 401(k) plan administrator has another. None of these parties knows what the others hold. The comparison only happens if someone asks all of them at the same time.
When the trust was last updated, was each beneficiary designation reviewed alongside it? If the answer is uncertain, the gap may already exist.
