How to find out who holds the right to your sister's account after she dies
The person named as beneficiary on your sister's bank account is whoever she listed on the beneficiary designation form when she opened the account or updated it later. That person has the legal right to claim the money in that account after she dies, without the account going through probate. You can find out who that is by asking the bank directly, or by reading her will and financial documents if she left them with you.
If your sister is still living, only she can see or change the beneficiary. If she has died, the bank will tell you who is named when you contact them with a death certificate. If no beneficiary was ever named, the money becomes part of her estate and is divided according to her will or state law.
Key Takeaways
- The beneficiary is the person your sister named on the bank's beneficiary designation form, not necessarily whoever is in her will.
- If your sister is alive, you cannot see the beneficiary information unless she gives you permission or adds you as an authorized user.
- If your sister has died, call the bank with her account number and a copy of her death certificate to learn who is named.
- Beneficiary designations on bank accounts override a will, so the named person gets the money even if the will says something different.
- If no beneficiary was named, the account becomes part of her estate and is divided by her will or state law.
What a beneficiary designation actually is
A beneficiary designation is a form the bank keeps on file that names who receives the account's money when the account holder dies. Your sister filled this out when she opened the account, or she can update it anytime while she is alive. The bank does not put this information in the will—it is a separate legal document that the bank controls.
This matters because beneficiary designations bypass probate. When your sister dies, the bank releases the money directly to the person named, without waiting for a court to process her will. That is why it is one of the fastest ways for money to reach someone after a death.
How to learn about your sister is alive
If your sister is still living and you want to know who she named, you have to ask her directly. Banks will not tell you the beneficiary of someone else's account, even if you are family. Your sister can show you the beneficiary form herself, or she can call the bank and authorize them to discuss it with you.
If you have power of attorney over her finances or are her legal guardian, you may be able to see this information, but you will need to show the bank the legal document that gives you that power. A regular family relationship is not enough.
Finding the beneficiary after your sister dies
After your sister dies, call the bank and ask to speak with someone in the probate or estate department. Have her account number ready, and tell them she has passed away. They will ask you to send a certified copy of her death certificate. Once they receive it, they will tell you who is named as beneficiary.
Different banks have different processes, but most will mail you a form to sign as well, confirming your relationship to the account holder. Some banks require the beneficiary themselves to contact the bank to claim the money. Ask the bank what the next step is once they confirm who is named.
What happens if there is no beneficiary named
If your sister never filled out a beneficiary form, or if the form was lost or never submitted to the bank, the account has no named beneficiary. In that case, the money becomes part of her estate. It will be divided according to her will if she left one, or according to your state's intestacy laws if she did not.
This process is slower because it goes through probate court. The court appoints an executor (usually named in the will) or an administrator (appointed by the court) to settle the estate. That person then distributes the money according to the will or state law. This can take several months to over a year, depending on the state and the complexity of the estate.
When a beneficiary designation overrides the will
If your sister's will says one person should get her money, but the bank beneficiary form names someone else, the beneficiary form wins. The person named on the beneficiary designation gets the account, and the will does not change that. This happens often when someone updates their will but forgets to update the beneficiary form on their accounts.
If you think this happened with your sister, and you believe it was a mistake, you may have grounds to challenge the beneficiary designation in court. This is complicated and expensive, and you would need a lawyer. The court will only overturn a beneficiary designation if there is evidence of fraud, undue influence, or a clear mistake in how the form was filled out.
What to do if you are the beneficiary
If the bank tells you that you are named as beneficiary, contact them to start the claim process. You will need to provide a certified death certificate and proof of your identity. The bank will give you a form to sign, and they will transfer the money to you. This usually takes one to three weeks after the bank receives all the documents.
The money you receive as a beneficiary is not subject to income tax, because it is not income—it is a transfer of the account holder's own money. You do not have to report it to the IRS. However, if the account earned interest after your sister died but before you claimed it, that interest may be taxable to her estate.
Frequently Asked Questions
Can I change my sister's beneficiary if I have power of attorney?
Power of attorney usually ends when someone dies, so you cannot use it to change the beneficiary after she is gone. If she is still alive, power of attorney may let you change it, but only if the document specifically says you can manage her bank accounts and the bank agrees to let you. Show the bank your power of attorney document and ask what they will allow.
What if my sister named someone who is now dead?
If the named beneficiary died before your sister, the account usually goes to your sister's estate instead, unless she named a backup beneficiary. Some banks let you name a "contingent beneficiary" who receives the money if the first beneficiary is already dead. Ask the bank whether your sister named one.
Can I see my sister's beneficiary form if I am her executor?
Yes. As executor, you have the right to see the beneficiary designation once your sister has died and you have provided the death certificate. The bank will not show it to you before she dies, even with the will. After her death, the beneficiary information is part of settling her estate, so the bank should release it to you.
What if the beneficiary refuses to claim the money?
If the named beneficiary does not want the money, they can refuse it in writing. The bank will then treat the account as if no beneficiary was named, and the money goes into your sister's estate. The beneficiary must do this in writing—just not claiming the money is not the same as refusing it.
Does the beneficiary have to share the money with other heirs?
No. The beneficiary keeps all the money in the account. Other heirs have no claim to it, even if your sister's will says they should. This is why beneficiary designations are so powerful—they override the will completely. If you think this is unfair, you would need to challenge the beneficiary designation in court, which is difficult and expensive.
