The Simplest Decision That Wasn't
Margaret Chen had been a retired schoolteacher in Plano for eleven years before her hip replacement surgery in February 2024. The surgery went well, but the recovery left her temporarily unable to drive, manage her own appointments, or navigate the online banking portal her credit union had switched to the prior spring. Her daughter Linda, who lived twenty minutes away in Frisco, was the obvious choice to help.
Margaret's estate plan was in good order. She had a will drawn up in 2019 by a Collin County attorney, leaving her home, her investment accounts, and all other assets in equal thirds to her three children — Linda, and her two sons, Kevin and Robert. She had a durable power of attorney and a medical power of attorney. She had told all three children the plan, and they had accepted it without complaint.
The bank account was not a legal decision in Margaret's mind. It was a practical one. She went to her credit union with Linda in March 2024, signed the account modification form the teller slid across the counter, and left with a new joint debit card issued to Linda. The account held $210,000 — the proceeds of a CD that had matured the prior year, parked there while Margaret decided what to do with it. "It's just so I can help Mom pay bills," Linda told her brothers when they visited that summer. Kevin and Robert did not object.
Margaret died of a stroke in September 2025. The account held $193,000. Linda, as the surviving joint account holder, owned every dollar of it the moment Margaret stopped breathing — not under Margaret's will, not by any decision of a probate court, but by operation of Texas law. Margaret's will, carefully drafted and properly signed, had nothing to say about the account. Kevin and Robert received their shares of the house and the investment accounts. They received nothing from the checking account that had held more than a third of their mother's liquid estate.
The family fractured. Linda believed she had done nothing wrong. Kevin and Robert believed they had been cheated. Margaret had believed she was making a temporary convenience arrangement. All three were right about the facts. Only Margaret was wrong about the law.
Why the Will Couldn't Help
Most Texans understand, in a general way, that a will controls who gets your stuff when you die. What most Texans do not understand is that a substantial portion of what they own — bank accounts, retirement accounts, life insurance policies, investment accounts — passes completely outside the will, governed instead by how the account is titled or who is named as a beneficiary.
Joint bank accounts in Texas are governed by the Texas Estates Code, specifically Chapter 113. Under § 113.152(a), the funds remaining in a joint account at the death of one party belong to the surviving party or parties "as against the estate of the decedent" — unless there is clear and convincing evidence of a different intent at the time the account was created. When Margaret signed that teller's form at the credit union, she created a joint account with right of survivorship. Texas law's default rule then made Linda's ownership of those funds on Margaret's death automatic, immediate, and legally airtight.
This rule exists for a legitimate purpose. Right-of-survivorship accounts simplify asset transfer between spouses, avoid probate delays for accounts that need to be accessed immediately after death, and reduce administrative burden for straightforward family situations. The problem is not with the law. The problem is the gap between what most people believe they are doing when they add a family member to an account and what Texas law actually makes happen.
Margaret believed she was giving Linda access during her own lifetime — a temporary, revocable arrangement that would end when she no longer needed help. What she actually created was an ownership interest that would survive her death, override her will, and transfer the account's balance to one of three intended beneficiaries regardless of anything she had written, signed, or said about her wishes.
The Five Dangers Most Families Don't See Coming
1. The Will Is Powerless Against a Joint Account
Your will operates on your probate estate — the assets you own in your own name at death that have no designated beneficiary or co-owner with survivorship rights. A joint account with survivorship never enters your probate estate. It transfers by contract, not by court order. A will that says "I give my accounts equally to my three children" cannot reach a joint account held with one of those children. The account goes to the surviving joint holder in full, and the will is silent on the matter.
This is the core danger: your estate plan can be technically perfect and still fail to accomplish your intent for assets that were unknowingly removed from its reach. An estate planning attorney reviewing your assets will spot this immediately. A notary at a bank branch will not.
2. The Account Is Exposed to Your Co-Owner's Creditors
Texas has some of the strongest creditor protection laws in the country for homesteads and certain personal property. Bank accounts are not among the assets protected. When you add someone to your account as a joint owner, that account becomes partially reachable by their creditors. If your co-owner has an outstanding civil judgment — from a business dispute, a car accident, an unpaid debt — a creditor can potentially levy the joint account, including funds you deposited.
This risk is not theoretical. Consider the situation of a McKinney retiree who added his son to his accounts for convenience, not knowing the son had a silent tax lien from an unpaid payroll tax obligation through a defunct business. The IRS can levy joint accounts for the tax debts of one joint owner. The parent's funds are exposed the moment that joint ownership is created.
3. Your Co-Owner Can Withdraw Everything During Your Lifetime
Under Texas Estates Code § 113.151, during the lifetimes of all account parties, each party may withdraw any or all of the funds in the account. The proportional ownership rule in that section governs who owns the money economically — but it does not prevent withdrawal. If Linda had chosen to move all $193,000 out of Margaret's account while Margaret was alive, she would have been legally able to do so. The only remedy would be a civil lawsuit for breach of fiduciary duty or conversion, which requires proving intent and is both expensive and uncertain.
Most children added to a parent's account out of genuine love would never do this. But "most" is not "all," and the scenario plays out in Texas courtrooms with painful regularity — often not through outright theft, but through gradual, unreflective use of account funds that the elder owner did not clearly authorize.
4. Medicaid Applications Become Complicated
Texas Medicaid eligibility for long-term care (nursing home coverage) is determined by counting an applicant's resources. A joint bank account is generally counted as a Medicaid resource — and the practical question of how much of the account is "the applicant's" can become a source of dispute with Texas HHSC (the Health and Human Services Commission). More importantly, transfers made within five years before a Medicaid application are subject to a look-back review. If Margaret's addition of Linda to the account — or any subsequent transfer of funds out of it — is characterized as a disqualifying gift, it could affect Margaret's Medicaid eligibility period. Long-term care planning requires knowing exactly how accounts are titled and what transfers have occurred. A joint account that looks like a convenience arrangement to the family can look like an impermissible asset transfer to a Medicaid caseworker. Our article on the Texas Medicaid five-year look-back period explains how this examination works in practice.
5. It Creates a Tax Basis Problem for Capital Gains
Questions about estate planning? A WG Law attorney can walk you through your options.
When you add a co-owner to an account during your lifetime, the transfer may be treated as a gift for federal gift tax purposes if the value transferred exceeds the annual exclusion ($18,000 per recipient in 2024). More subtly, assets that would receive a stepped-up cost basis at death — eliminating capital gains on appreciation during the owner's lifetime — may not receive that step-up for the portion deemed transferred as a gift before death. While checking accounts don't hold appreciated securities, investment accounts structured as joint accounts can trap heirs with unnecessary capital gains tax. See our article on how stepped-up basis works for a related discussion of how asset transfers affect tax treatment.
What You Should Have Done Instead
The goal Margaret was trying to accomplish — giving Linda the practical ability to manage finances during a recovery period — is entirely legitimate. There are legal mechanisms designed precisely for that purpose that would have achieved it without creating the survivorship trap.
Durable Power of Attorney
A durable power of attorney grants a named agent legal authority to act on your behalf for financial matters. It can be as broad or as limited as you specify — including the authority to access bank accounts, pay bills, and manage investments. Crucially, it does not change who owns the assets or who inherits them. Linda could have had full authority to manage Margaret's accounts without becoming a joint owner, without triggering survivorship rights, and without affecting the accounts' distribution under the will. The power of attorney terminates at death; the estate then passes per the will. This is precisely what a durable power of attorney is designed to do. Our article on why every Texan needs a power of attorney covers the practical mechanics of this document.
Payable-on-Death Designations
A payable-on-death (POD) designation — also called a beneficiary designation — allows you to name one or more people to receive an account's balance upon your death, while retaining sole ownership and full control during your lifetime. POD accounts pass outside probate like joint accounts, but without the survivorship risk during life or the creditor exposure. Margaret could have named all three children as equal POD beneficiaries on her checking account, preserving her intent that the balance be divided in thirds at death, while keeping the account solely in her own name and control. Kevin and Robert could have each been named for their shares without Linda having any ownership claim during Margaret's lifetime.
Revocable Living Trust
For larger estates or situations where the distribution structure is more complex, a revocable living trust provides the most comprehensive solution. Assets funded into the trust are managed by a trustee — often yourself during your lifetime, with a successor trustee who takes over at incapacity or death. The trust document controls distribution at death with far more specificity than a will and passes entirely outside probate, but unlike joint accounts, the trust's terms are set by the grantor and remain enforceable. If Margaret had placed her accounts in a revocable trust with a provision for Linda to serve as successor trustee at incapacity, Linda could have managed the accounts fully during Margaret's recovery without acquiring any ownership interest that would affect the three-way equal distribution at death. For an explanation of how revocable trusts work and why they are often preferable to wills alone in Texas, see our article on why trusts are essential in Texas estate planning.
A Word About "Convenience Accounts" Under Texas Law
Texas Estates Code § 113.056 recognizes "multiple-party accounts without right of survivorship" — accounts structured so that a co-owner can access funds during the primary owner's lifetime but the co-owner's status does not create survivorship rights. These are sometimes called "convenience accounts." The account's funds, at the primary owner's death, pass through the estate rather than directly to the co-owner.
This tool exists but is not commonly offered or explained at bank branches. The standard joint account form at most Texas financial institutions creates a right of survivorship by default. Getting a different result requires specifically requesting a non-survivorship joint account, understanding what you are signing, and confirming that the institution will structure the account as intended. Most Texans who add a family member to an account at a branch never have this conversation.
Even when a convenience account is properly set up, it still carries the risk of lifetime withdrawal — the co-owner can still legally access the funds. The power of attorney remains the cleaner tool for the limited purpose Margaret actually had in mind.
Back to Plano
Margaret Chen was not careless. She was not uninformed in a general sense. She had a properly drafted will, understood the concept of estate planning, and had consulted an attorney years before her hip surgery. What she did not know — could not have known without specific guidance — was that the two-minute transaction at her credit union branch would remove $193,000 from the reach of her estate plan and hand it entirely to one child regardless of everything else she had documented about her wishes.
Kevin and Robert are not pursuing litigation against Linda. The legal situation is clear enough that an attorney would tell them they have no viable claim against their sister. The law did exactly what the law does. Their quarrel, if they have one, is with a system they were never told to watch out for, a form they never saw, and an estate plan they had every reason to believe covered the full picture of their mother's assets.
It didn't cover the checking account. It never had a chance to.
If you have added a family member to a bank or investment account — or if you are considering doing so — the time to understand the consequences is before the form is signed. At WG Law, our estate planning attorneys, including Taylor Willingham and Carla Alston, conduct comprehensive estate plan reviews that include how your accounts are titled, what beneficiary designations exist, and whether the structure of your assets actually matches your intentions. A review often surfaces gaps exactly like this one — gaps that feel small at the time and become irreversible at death.
