Here is something that catches most people off guard: banking beneficiaries, not your will, usually decide who inherits your bank accounts. People spend real effort on a will or trust and then never think about the beneficiary form they signed at the bank, which quietly controls where those funds go. Worse, in California a beneficiary or survivorship designation on an account can override what your will says entirely. Understanding how each type of account works is the difference between your money going where you intend and going somewhere you never meant.

Banking beneficiaries govern who receives the funds in an account when the account holder dies, and they vary by the type of account. In California, most of these rules come from the Multiple-Party Accounts Law in the Probate Code. Here are the four arrangements you are most likely to encounter.
Trust Accounts
A trust account is a bank account held inside a living trust, also called a revocable or inter vivos trust. The account is opened in the name of the trust, and the trustee manages the funds on behalf of the trust. The person who creates the trust, the grantor or settlor, transfers assets into it for the benefit of themselves and their chosen beneficiaries. To open one, the bank typically wants to see the trust agreement or a certificate of trust.
The primary advantage is avoiding probate. When the grantor dies, the funds in the trust account pass to the trust’s beneficiaries under the terms of the trust document, without a court proceeding. This is usually the most flexible option, because the trust can spell out exactly how and when beneficiaries receive the money.
Totten Trusts and POD Accounts
A Totten trust, also called an informal revocable trust or payable-on-death (POD) account, is the simplest tool. The account holder names a beneficiary to receive the funds at death but keeps complete control during their lifetime, free to spend, withdraw, or change the beneficiary at any time. The beneficiary has no access or rights at all while the account holder is alive.
POD accounts usually require no formal legal documents. The account holder just completes the bank’s beneficiary designation form. At death, the funds pass automatically to the named beneficiary outside of probate, which makes this one of the easiest ways to keep an account out of court. For a church member who wants to leave a specific account to a person or even to the church itself, a POD designation is often the cleanest route.
Joint Accounts
In a joint account, a co-owner has rights to the funds while the original holder is alive; each holder has an equal ownership interest and can deposit, withdraw, and manage the money. The key feature at death is the right of survivorship. When one holder dies, the funds generally pass automatically to the surviving holder or holders outside of probate, giving them immediate access.
Joint accounts are convenient, but they carry a trap worth naming. Adding someone as a joint owner gives them full access to the money now, not just at death, and the survivorship result can defeat what your will intended. Under California Probate Code section 5302, sums in a joint account belong to the surviving party at death unless there is clear and convincing evidence of a different intent, a high bar to meet after the fact.
The Banking Beneficiaries Rule That Surprises People Most
Here is the point I most often have to make clear: these designations generally beat your will. Under the California Multiple-Party Accounts Law, a right of survivorship on an account, a Totten trust beneficiary, or a POD payee designation cannot be changed by will. You can write “I leave my savings account to my children” in your will, but if that account names your brother as the POD payee, your brother gets the money. Your will does not touch it.
That is why banking beneficiaries deserve as much attention as the will itself. They are not an afterthought; for those accounts, they are the actual plan.
If You Name No One
If an account has no designated beneficiary and is not held jointly, the funds become part of your estate at death. From there, they are distributed under your will, or, if you have no valid will, under California’s laws of intestate succession, which may or may not match what you would have chosen. Leaving it to chance is rarely the plan anyone actually wants.
Banking Beneficiaries and Your Church
For a church member, banking beneficiaries are one of the simplest ways to leave a lasting gift to the congregation. Naming your church as the payable-on-death beneficiary of a bank account lets the funds pass directly to the church at your death, outside of probate, without tying the gift up in the estate or a will contest. The church receives the money quickly and cleanly, and you keep full control of the account during your lifetime.
Churches receiving such gifts should understand the mechanics too. Because banking beneficiaries operate outside the will, a POD gift to the church is not affected by the rest of the estate plan, which can be a real advantage when a family situation is complicated. It also means the church should confirm the designation is current and properly completed, since a lapsed or incorrectly filled beneficiary form can undo the donor’s intent entirely.
Review Your Banking Beneficiaries Regularly
Because banking beneficiaries control real money and override your will, they deserve a periodic review, not a one-time signature and a filing cabinet. Life changes, a marriage, a divorce, a death, a new child or grandchild, or a decision to support your church, can all make an old designation wrong. A beneficiary form completed years ago may still name an ex-spouse, a person who has since died, or no one at all.
Regularrly reviewing every account’s beneficiaries whenever your estate plan changes, and coordinate the designations with your will and trust so they work together rather than at cross purposes. Because banking beneficiaries beat the will, this coordination is not optional; it is the only way to be sure your accounts and your estate plan tell the same story.
