One person worked through a parent's long-term care paperwork under Texas law and wrote down which steps required a lawyer and which the family handled alone. Nothing here is legal advice for your situation.
The file that starts a Texas guardianship usually begins the same way: a parent is already past the point of signing anything, the bank will not talk to anybody, and a search of the house turns up an old will and nothing else. No durable power of attorney, no medical power of attorney, no declaration of guardian signed in advance. At that point the family cannot fix the problem with paperwork, because the person who would have to sign the paperwork no longer can. What is left is a court proceeding, and the court is not a formality. It is a contested-by-design process with an assigned adversary, a medical evidentiary requirement, and reporting duties that outlast the hearing by years.
1. The physician's certificate, and how fresh it has to be
Nothing moves without a Certificate of Medical Examination signed by a physician who has actually examined the proposed ward. Texas requires that the examination be recent, dated within 120 days before the application is filed, so a diagnosis letter from two years ago will not carry the filing. The certificate has to describe the nature and degree of incapacity in functional terms: whether the person can manage financial matters, make medical decisions, or handle personal care, and whether the condition is expected to improve. A careful reader checks the examination date before anything else, then checks that the physician answered the capacity questions rather than simply naming a diagnosis.
2. The attorney ad litem who is not on your side
Once the application is filed, the court appoints an attorney ad litem to represent the proposed ward, and that attorney's client is the parent, not the family. The appointment is mandatory, the fee is generally paid from the proposed ward's estate, and the ad litem is expected to meet the person, review the medical evidence, and press the case for keeping rights intact. Some counties also assign a court investigator, and in a genuine dispute the judge can add a guardian ad litem. Families who expect a rubber stamp are surprised by this; families who expect scrutiny find the process moves in a predictable order.
3. The alternatives the judge has to rule out
Texas law does not let a court create a guardianship simply because one would be convenient. The judge must find, by clear and convincing evidence, that the person is incapacitated, and must also find that alternatives to guardianship and available supports and services were considered and were not feasible. Those alternatives are real and specific: a supported decision-making agreement, a management trust, a joint account arrangement, a representative payee for benefit income. The Social Security Administration is the agency responsible for the representative payee program, and where a parent's only asset is a monthly benefit check, a payee appointment may resolve the entire problem without a courtroom.
4. What a contested application actually costs
An uncontested guardianship where the family agrees, the medical evidence is clean, and the estate is modest carries a fairly bounded cost: the applicant's attorney, the filing fee, the ad litem fee, the physician's charge, and a bond if there is an estate to manage. A contested one is a different animal. When two siblings file competing applications, or the proposed ward's own attorney fights the finding of incapacity, the case acquires depositions, expert testimony, and hearing days, and the fees are paid out of the same estate the guardianship is supposed to protect. Ask any attorney for a written fee structure and for an honest read on which relatives are likely to object.
5. The reporting that starts the day you are appointed
Appointment is the beginning of an ongoing obligation, not the end of a case. A guardian of the person files an annual report on the ward's condition, residence, and care. A guardian of the estate files an annual accounting that reconciles every dollar in and out, supported by statements, and files an inventory near the start. Guardians must complete a required training course and register with the court, and the estate guardian usually posts a bond set by the judge. Missed accountings draw show-cause notices, so the practical question before you apply is who in the family will keep the records.
The narrower answer is often the better one. Texas courts can grant a limited guardianship that removes only the specific rights the evidence supports removing, leaving the rest with the parent, and a family that walks in with a functional medical certificate and a documented look at the alternatives tends to get a cleaner, cheaper order.
