Authorized signer
Somebody a bank permits to transact on an account they do not own. It is access without ownership, and it ends at the account holder's death.
What it means
An authorized signer can deposit, withdraw, transfer and pay bills on an account that remains entirely the account holder's. They own none of the money and inherit none of it.
It is not the same thing as being a joint owner, although a bank may offer both in the same conversation and use overlapping words for them. The distinguishing question is not what it is called but whether it changes who owns the money.
The permission ends when the account holder dies. What happens to the balance at that point is decided by the account's own titling and by any beneficiary designation, not by who was allowed to sign.
On a credit card the equivalent arrangement is usually called an authorized user, and it is narrower still: it permits the card to be used and nothing else.
Why it matters
It is the arrangement that does the job most families actually want — paying a parent's bills — without the consequences that make joint ownership hard to reverse.
Because it ends at death, a family that arranged only this and believed it covered everything discovers the gap at the worst moment. It is the complement to a beneficiary designation, not a substitute for it.
When you are likely to meet it
- When a bank offers to 'put you on the account'.
- When you are trying to pay a parent's bills and do not want to own their money.
- When an account holder has died and you are working out what your existing permission still allows.
How this varies by state
What an institution offers short of joint ownership, and what it calls it, differs by bank and by product. Some states have created their own statutory version of the same idea with rules of its own.
