Parent has dementia and no will — hearing those words can make your stomach drop. You may feel panicked, but take a breath. Families face this situation every day, and there is a clear path forward. You are not too late to protect your parent and your family. The law has tools designed for exactly this moment. However, the steps you take now — and how quickly you take them — matter a great deal.
Where You Stand: Parent Has Dementia and No Will
When a parent has dementia and no will, the biggest question is capacity. “Testamentary capacity” is the legal term for the mental ability to sign a valid will. According to the Cornell Legal Information Institute, a person needs to understand four things: what a will is, who their family members are, what property they own, and how they want it distributed. A dementia diagnosis alone does not automatically remove this ability.
In most cases, someone with mild or early-stage dementia may still have enough capacity to sign a will and power of attorney. However, this window can close quickly. As a result, time is your most important resource. If your parent has dementia and no will, acting now — even today — gives your family the best chance of avoiding a long, expensive court process later.
If your parent has already lost capacity, the estate will eventually pass through your state’s intestacy laws. These laws decide who inherits when there is no will. The rules vary by state, and so do the costs of the court process that may be required.
| State | Guardianship Filing Fee | Spouse’s Intestacy Share (with children) | Small Estate Threshold |
|---|---|---|---|
| California | $435 (conservatorship of estate) | All community property + ½ or ⅓ of separate property | $184,500 |
| Texas | $360 (varies by county) | All community property + ⅓ of separate personal property for life | $75,000 |
| Illinois | $105 (estates over $15,000) | ½ of entire estate | $100,000 |
| New York | $210 (Article 81 guardianship) | First $50,000 + ½ of remainder | $50,000 |
| Florida | $400 (varies by circuit) | ½ of entire estate | $75,000 |
What to Do First (Step by Step)
When a parent has dementia and no will, here is what to do right away. First, ask your parent’s doctor for a capacity evaluation. This is a medical assessment that determines whether your parent can still understand legal documents. If the doctor says yes, you have a window to act.
Second, contact an elder-law attorney or your local legal-aid office. Many offer free or low-cost consultations for families in this situation. Third, if your parent has capacity, work with the attorney to sign three documents: a will, a durable power of attorney for finances, and a healthcare directive.
If the doctor says your parent no longer has capacity, the path changes. You will likely need to petition the court for guardianship or conservatorship. This gives a family member legal authority to manage your parent’s affairs. For example, in California this is called a “probate conservatorship,” while in New York it falls under Article 81 guardianship. Typically, the court will appoint an investigator, notify your parent, and hold a hearing.
Fourth, look into less restrictive alternatives before pursuing full guardianship. Many states now recognize supported decision-making agreements, where your parent keeps their rights but gets help from a trusted person. The Administration for Community Living has details on these programs. A limited guardianship — covering only finances, for example — may also be an option in your state.
How to Protect Yourself and Keep Records
When a parent has dementia and no will, paperwork becomes your best friend. Start a folder — physical or digital — and keep copies of everything. This includes medical records, bank statements, property deeds, insurance policies, and any bills your parent owes. If you are paying for your parent’s care out of pocket, save every receipt. Courts may ask for an accounting of how money was spent.
If your parent has dementia and no will, write down what they tell you about their wishes while they can still communicate. These notes are not a legal substitute for a will, but they can help a court understand your parent’s intentions. For example, if your parent says they want the house to go to a specific child, note the date, time, and who was present. However, do not rely on verbal wishes alone — always pursue formal legal documents if capacity exists.
Keep a log of your parent’s daily condition. Note good days and bad days. Record any conversations with doctors, social workers, or attorneys. This record can be critical if a family member later challenges a guardianship or disputes how assets were handled. In most cases, the family member who keeps the best records has the strongest position in court.
When to Get Help (Probate Court or an Attorney)
If your parent has dementia and no will, your first call should be to your county probate court’s self-help desk. Many courts have free staff who can explain the guardianship petition process, give you the right forms, and tell you the exact filing fees. For example, California’s court self-help centers offer free guidance and fee waivers for families who qualify based on income.

Frequently Asked Questions
Can my parent still sign a will after a dementia diagnosis?
Possibly. A dementia diagnosis does not automatically mean your parent lacks testamentary capacity. The legal standard is lower than you might expect. If your parent can understand what a will does, who their family is, and what they own, they may still be able to sign a valid will. However, you should act immediately and have a doctor document their capacity the same day the will is signed.
What happens if my parent has dementia and no will and then passes away?
The estate will go through probate under your state’s intestacy laws. The court decides who inherits based on a fixed formula — typically the surviving spouse gets the largest share, then children split the rest equally. As a result, your parent’s personal wishes will not be followed. The process can take months and may cost thousands of dollars in court and attorney fees.
How much does guardianship cost, and can I get the fees waived?
Filing fees range from $50 to $435 depending on your state and county. Additional costs may include court investigator fees, attorney fees, and annual reporting requirements. However, most states offer fee waivers for families with limited income. Contact your county probate court clerk to ask about income-based fee waivers before you file.
