Texas dementia laws give families a set of legal tools that depend heavily on timing. While a person still understands what they are signing, they can put powers of attorney, a medical directive, and a supported decision-making agreement in place. Once dementia has progressed far enough that they no longer have legal capacity, those documents are off the table and the only remaining option is guardianship through probate court.
Capacity Is What Decides Which Tools You Can Use
Texas law presumes every adult is mentally competent, and that presumption stands until a court finds otherwise.1State of Texas. Texas Health and Safety Code 576.002 – Presumption of Competency A dementia diagnosis by itself does not remove anyone’s legal rights. Many people in early and moderate stages can still sign documents, handle routine finances, and make medical choices. The legal question is whether the person understands what they are doing at the moment they act.
For guardianship, the Texas Estates Code defines an “incapacitated person” as an adult who, because of a physical or mental condition, cannot adequately provide their own food, clothing, or shelter, care for their own physical health, or manage their own financial affairs.2State of Texas. Texas Estates Code 1002.017 – Incapacitated Person That is the threshold a probate court applies before appointing a guardian.
The practical takeaway is simple. Planning documents have to be signed while the person still has capacity. Waiting until a crisis usually means the family has already lost the option to use them.
The Planning Documents to Sign Early
Texas provides three core documents that let a person with early dementia decide, in advance, who will handle their money and their medical care later.
Statutory Durable Power of Attorney
A statutory durable power of attorney lets the principal name an agent to handle financial matters. “Durable” is the key word: the agent’s authority survives the principal’s later incapacity rather than ending when the principal can no longer supervise the agent. The principal selects specific powers to grant from a statutory menu that covers real estate, banking, insurance, retirement accounts, taxes, and digital assets.3State of Texas. Texas Estates Code 751.0021 – Requirements of Durable Power of Attorney
The principal must sign the document and have the signature acknowledged before a notary or another officer authorized to take acknowledgments and administer oaths.3State of Texas. Texas Estates Code 751.0021 – Requirements of Durable Power of Attorney If the agent will act on real estate, the power of attorney has to be recorded with the county clerk in each county where the property is located.
Medical Power of Attorney
A medical power of attorney names an agent to make healthcare decisions once the principal can no longer make them. The document can be executed either before a notary or in the presence of two competent adult witnesses.4State of Texas. Texas Health and Safety Code 166.164 – Form of Medical Power of Attorney
The witness rules are strict. Neither witness may be the designated agent, a blood or marriage relative, someone entitled to inherit from the principal, the attending physician or an employee of the physician, a healthcare facility employee who provides direct care to the principal or serves as an officer or director of that facility, or anyone with a financial claim against the principal’s estate.4State of Texas. Texas Health and Safety Code 166.164 – Form of Medical Power of Attorney The agent will eventually hold decisions about life-sustaining treatment, and the law keeps people with a financial interest out of the signing room.
Directive to Physicians
A directive to physicians, sometimes called a living will, records the principal’s own preferences about life-sustaining treatment such as mechanical ventilation or artificial nutrition if they become terminally or irreversibly ill. It is governed by Chapter 166 of the Texas Health and Safety Code and works alongside the medical power of attorney, giving the healthcare agent concrete guidance rather than leaving them to guess.
Originals should be kept somewhere secure but accessible. Copies should go to the named agents, the primary care physician, and any healthcare facility providing regular care, so nobody is hunting for paperwork during an emergency.
Supported Decision-Making Agreements
Texas offers a middle option that sits between full independence and a power of attorney: the supported decision-making agreement, authorized under Chapter 1357 of the Texas Estates Code. An adult with a disability, including cognitive impairment, keeps the legal right to make their own decisions while designating a trusted “supporter” to help them understand options and communicate their choices.5State of Texas. Texas Estates Code 1357.056 – Form of Supported Decision-Making Agreement
The supporter cannot decide anything for the person. Their role is limited to helping access relevant information such as medical records or financial documents, helping the person understand their options, and helping communicate the person’s decision to others. The supporter must act in good faith, stay within the authority granted, and avoid conflicts of interest.5State of Texas. Texas Estates Code 1357.056 – Form of Supported Decision-Making Agreement
For someone in early dementia who can still decide with some help, this arrangement preserves far more autonomy than a power of attorney or guardianship. It matters later, too: Texas law requires courts to consider less restrictive alternatives before imposing a guardianship, and an existing supported decision-making agreement can meet that requirement in the right case.
When Guardianship Becomes the Only Option
If a person with dementia has no advance planning documents and can no longer manage their affairs, the remaining path is guardianship in probate court. It is the most restrictive and most expensive route, and it comes with court oversight that also protects the ward from exploitation.
Texas treats guardianship as a last resort. Before appointing a guardian, the court must find by clear and convincing evidence that alternatives like powers of attorney, supported decision-making, and trusts have been considered and are not feasible. Any guardianship the court does create must be only as restrictive as the person’s actual limitations require.
The application must include detailed information about the proposed ward: name, date of birth, address, the nature and degree of the incapacity, and an approximate description and value of the property, including any pensions, insurance, and government benefits received.6Justia Law. Texas Estates Code 1101 – Guardianship Application The applicant also has to disclose the names and addresses of the proposed ward’s spouse, parents, siblings, and adult children.
A physician’s letter or certificate is required for any adult guardianship based on a physical or mental condition. The examination must have taken place no earlier than 120 days before the application is filed. The physician has to describe the nature, degree, and severity of the incapacity, and address specific functional questions: whether the person can handle financial matters, operate a vehicle, decide where to live, and consent to medical treatment, and whether they can understand and communicate, recognize familiar people, solve problems, reason logically, and perform daily living activities with and without help.7State of Texas. Texas Estates Code 1101.103 – Determination of Incapacity of Certain Adults
The Hearing, the Bond, and the Letters
Once the application is filed, a citation has to be personally served on the proposed ward, if age 12 or older, along with the spouse, parents, and any person with custody or care of them.8State of Texas. Texas Estates Code 1051.103 – Service of Citation for Application for Guardianship The court appoints an attorney ad litem to represent the proposed ward throughout the proceeding.9Texas Legislature. Texas Estates Code Chapter 1054 – Court Officers and Court-Appointed Persons The proposed ward has a right to be heard, no matter how advanced the dementia may be.
At the hearing, the judge weighs the medical evidence and testimony to decide whether guardianship is truly necessary and, if so, how limited it can be. A judge might grant guardianship over financial matters only, over personal decisions only, or both. The order can preserve specific rights for the ward, such as choosing where to live or voting, if the evidence shows the person retains capacity in those areas.
An appointed guardian takes a formal oath to faithfully discharge their duties.10State of Texas. Texas Estates Code 1105.051 – Oath or Declaration of Guardian A guardian of the estate also has to post a bond. The bond amount equals the estimated value of the ward’s personal property plus anticipated income over the next twelve months from interest, dividends, rents, and other sources.11State of Texas. Texas Estates Code 1105.154 – Specific Bond Amount After these steps, the clerk issues letters of guardianship, the official document that authorizes the guardian to act.12State of Texas. Texas Estates Code Chapter 1106 – Letters of Guardianship
Those letters are not permanent. They expire one year and 120 days after issuance. The court can extend them for up to another year, but only if the guardian has filed the required annual account and the court has approved it.12State of Texas. Texas Estates Code Chapter 1106 – Letters of Guardianship The built-in expiration keeps the court in the loop and blocks any guardian from operating indefinitely without accountability.
What a Guardian Has to Do After Appointment
Becoming a guardian creates continuing legal obligations. Within 30 days of qualifying, a guardian of the estate must file an inventory, appraisement, and list of claims that reflects the fair market value of assets as of the appointment date.
After that, the guardian files a detailed annual accounting with the court covering:
- All claims presented against the estate, and whether each was allowed, paid, or rejected.
- Any newly discovered property or changes to previously listed assets.
- All money received and disbursed, with principal and income listed separately.
- A description of the property the estate holds, its condition, and how it is being used.
- The current cash balance and the bank holding it.
- For bonds, notes, and other securities: the obligor, maturity date, interest rate, and serial numbers.
The annual account is due within 60 days of each anniversary of the guardian’s qualification.13State of Texas. Texas Estates Code 1163.001 – Annual Account Missing that deadline is not a formality. The letters of guardianship cannot be renewed without a filed and approved annual account, which effectively suspends the guardian’s authority.
Reporting Abuse, Neglect, and Financial Exploitation
Chapter 48 of the Texas Human Resources Code requires anyone who has cause to believe an elderly person or a person with a disability is being abused, neglected, or exploited to report it. The duty is not limited to healthcare professionals. Family members, neighbors, financial advisors, and any other person who suspects maltreatment must report.14Texas Department of Family and Protective Services. APS Abuse Hotline – Who Should Report Abuse
Reports go to the Texas Department of Family and Protective Services through the Texas Abuse Hotline at 1-800-252-5400 or at TxAbuseHotline.org.15Texas Health and Human Services. 3200, Abuse and Neglect Reporting Reports should include the victim’s name, age, and address, specific details of the suspected maltreatment, and the identity of the alleged perpetrator if known.
Knowingly failing to report is a Class A misdemeanor, punishable by up to one year in jail and a fine of up to $4,000. The offense rises to a state jail felony if the victim is a person with an intellectual disability living in a state-supported living center or licensed care facility and suffered serious bodily injury.16State of Texas. Texas Human Resources Code 48.052 – Failure to Report People with dementia are frequent targets of financial exploitation, and the reporting duty exists because many victims cannot advocate for themselves.
Medical Expense Deductions for Dementia Care
Dementia care is expensive, and the tax code offers one meaningful offset. Medical expenses, including memory care facilities, in-home nursing, physician visits, and prescription medications, are deductible on Schedule A to the extent they exceed 7.5% of adjusted gross income.17Internal Revenue Service. Topic No. 502, Medical and Dental Expenses Dementia care costs often clear that threshold quickly.
If the principal reason for a nursing home or memory care facility stay is the availability of medical care, the full cost, room and board included, qualifies as a deductible medical expense. If medical care is not the principal reason for the stay, only the portion actually attributable to medical care is deductible.17Internal Revenue Service. Topic No. 502, Medical and Dental Expenses For most dementia patients placed in memory care, the medical-necessity requirement is straightforward to document.
Only unreimbursed expenses count. If Medicare, Medicaid, or long-term care insurance covers part of the cost, only the remainder is deductible. Families paying out of pocket for in-home caregivers or adult day programs should keep detailed records when the care is medically necessary and performed under a plan of care.
Social Security and the Representative Payee
Social Security benefits sit outside the reach of a standard power of attorney. When a person with dementia can no longer manage their benefits, the Social Security Administration appoints a representative payee: the person or organization authorized to receive and manage payments on the beneficiary’s behalf. A financial power of attorney or authorized-representative status on other accounts does not grant this authority. Only a formally appointed representative payee can manage Social Security funds.
To apply, contact Social Security at 1-800-772-1213 or visit a local office. The process usually involves an in-person interview, and the agency reviews medical evidence and statements from doctors, relatives, and others familiar with the beneficiary’s ability to manage money. A beneficiary can also designate a preferred future payee in advance, which is worth doing as part of early-stage dementia planning. The payee has to keep Social Security funds in a separate account titled in the beneficiary’s name, and some payees must submit annual reports accounting for how benefits were spent.
