Can a bank freeze a joint account when one holder dies?
PARTIAL — a genuine, disclosed gap, not a formality
This is general information, not legal advice. Two different things are true at once here, and conflating them is where the confusion usually comes from: who legally owns the money is a different question from whether the bank restricts access while it figures that out, and we could verify the first cleanly but not the second.
On ownership, the CFPB (the federal Consumer Financial Protection Bureau) is direct: "Most joint bank or credit union accounts are held with 'rights of survivorship.' This means that when one account owner dies, the money passes to the surviving owner, or equally to the rest of the owners if there are multiple people on the account." The alternative titling, "tenants in common," works differently: "that person's share of the account passes to their heirs," via the will or state inheritance law rather than automatically to the co-owner. Source Under the far more common survivorship titling, the surviving joint owner legally owns the money the moment the other owner dies — there is no probate step required for that transfer.
What we could not find a primary source specifically addressing is whether a bank's systems still temporarily restrict a joint account's online or card access on notice of a death, the way Bank of America documents doing for a sole-owner account (Q28: "Suspending Online and Mobile Banking user ID and Telephone Banking, including Bill Pay" is listed among the "protective actions" Bank of America takes on notification of a death). That earlier-verified language describes protective actions taken on notice of a customer's death; it does not specify whether those same suspensions apply identically to a joint account where a co-owner is still alive and still needs access, or whether banks treat that scenario differently in practice. We were not able to locate a bank policy page in this pass that speaks to the joint-account case specifically, one way or the other.
The practical, honest guidance: the money is very likely already legally the survivor's under a standard rights-of-survivorship account, but that doesn't guarantee uninterrupted access to it — notifying the bank promptly and asking directly what happens to online/card access on a joint account specifically (rather than assuming either "nothing changes" or "everything freezes") is the only way to know for a given bank.
What we could not verify: any bank's documented policy on restricting a joint account's access (as opposed to a sole-owner account) upon notice of one holder's death. This is a genuine gap in the sourcing, not something we're glossing over.
