A son from Queens called me last week. His mother had a fall, and while she was recovering, he needed to pay her bills—the mortgage, the ConEd bill, her caregiver. He went to her bank, armed with a note from his mom, but the teller refused. “The only way is for your mother to add you as a joint owner on the account,” the teller advised. He called me to ask if this was a good idea.
I told him what I tell every client who asks this question: It’s a terrible idea. While the bank teller’s suggestion comes from a place of convenience, it is one of the most common and damaging mistakes a family can make. It’s a shortcut that bypasses the thoughtful stewardship required to protect a parent’s legacy, and it can create legal and financial problems that last for years.
Adding your name to a parent’s bank account isn’t just about access. In the eyes of the law, it’s about ownership. And that distinction is everything.
The Illusion of Convenience vs. The Reality of Ownership
When you become a joint owner of a bank account, you are not simply a helper or a manager. You are a co-owner of every dollar in that account. This might seem practical for paying bills, but it has three immediate and dangerous consequences most people never consider.
First, your parent’s money is now exposed to your personal creditors. If you are sued after a car accident, go through a divorce, or have a business debt, that joint account can be targeted for seizure. The court does not care that the money was originally your mother’s; your name on the account makes it legally available to satisfy your debts. A parent’s life savings, meant for their care, can be wiped out by a child’s unrelated financial trouble.
Second, this action can disrupt your parent’s eligibility for government benefits. If your parent ever needs long-term care and must apply for Medicaid, the state performs a five-year “look-back” at their financial history. Adding a child’s name to an account is often treated as a gift or a transfer of assets, creating a penalty period during which your parent will be ineligible for benefits—often at the exact moment they need them most.
Finally, and perhaps most painfully, it can tear a family apart.
How a Bank Account Can Bypass a Will
This is the critical point bank tellers rarely explain. In New York, joint bank accounts come with a powerful legal feature known as a “right of survivorship.” This is codified in New York Banking Law § 675, which creates a legal presumption that when one joint owner dies, the money in the account automatically and immediately belongs to the surviving owner.
It does not matter what your parent’s will says. It does not matter if the will directs that all assets be split equally among three children. If one of those children is a joint owner on the bank account, that account is not part of the probate estate. The funds pass directly to that one child, outside the will. I have seen this happen time and again. A parent adds their most local or “most helpful” child to the account for convenience, fully intending for the money to be shared upon their death. But the law operates differently. The helpful child legally inherits the entire account, and the other siblings are unintentionally disinherited from that asset.
What follows is often a bitter and expensive legal battle in Surrogate’s Court, with siblings accusing one another of undue influence or theft. The family’s trust is broken, and the parent’s true intentions are lost in a fight they never wanted.
The Right Tool for the Job: Fiduciary Duty
Helping a parent manage their finances does not require co-ownership. It requires authority. The law has a much better and safer tool designed for precisely this situation: the Durable Power of Attorney.
A Power of Attorney is a legal document where your parent (the “principal”) appoints you (the “agent”) to act on their behalf in financial matters. With a properly drafted Power of Attorney, you can:
- Sign checks and pay bills from your parent’s account.
- Manage their investments.
- File their taxes.
- Speak to banks and government agencies on their behalf.
Crucially, you do all this as a fiduciary. You are a steward of their money, not an owner. Their assets remain their own, shielded from your creditors and separate from your personal finances. The Power of Attorney does not override their will or change their estate plan. It is a tool for managing their affairs while they are alive, and its power ends upon their death, at which point their will takes over as intended.
For families with more significant assets, establishing a revocable living trust can be an even more effective strategy. Your parent can place their accounts and other assets into the trust and name a co-trustee or successor trustee (like you) to manage them. This provides for a seamless transition of management if they become incapacitated and, like a Power of Attorney, avoids all the pitfalls of joint ownership.
The impulse to help an aging parent is a good one. But good intentions can lead to devastating outcomes when you use the wrong legal tools. The convenience of a joint bank account is a mirage that hides deep financial and familial risks.
If you are in a position where you need to assist a parent with their finances, the correct first step is not a trip to the bank. It is a deliberate conversation about establishing the proper legal authority. I invite you to schedule a call with my office to review your parent’s situation and discuss the fiduciary documents needed to protect their legacy and your family’s harmony.
