The Risks to Your Estate if You’re Diagnosed With Dementia Without a Plan in California

A dementia diagnosis changes everything, especially when it comes to protecting your assets and ensuring your wishes are followed. In California, waiting too long to create an estate plan can leave your family facing costly court battles, frozen bank accounts, and decisions made by strangers instead of loved ones.
When dementia progresses, you may lose the legal capacity to make important financial and healthcare decisions. Without proper planning in place, your family will likely need to go through conservatorship proceedings. This is a lengthy, expensive court process that can drain your estate and create family conflict.
The good news is that California law provides several tools to protect your assets and maintain control over your care, but only if you act while you still have mental capacity. Understanding these risks and your options can help you make informed decisions about your future and give your family the guidance they need during a difficult time.
If you’re dealing with a recent diagnosis or watching a loved one’s condition change, time matters. At John Park Law, we’re here to help you before it gets too tough. Our California estate planning attorneys will fight for your family’s financial security.
How Dementia Affects Your Legal Capacity Under California Law
California Probate Code Section 811 defines legal capacity as the ability to understand the nature and consequences of your decisions and communicate them clearly. The law recognizes that mental disorders, including dementia, can impair this capacity even when you have good days or moments of clarity.
For estate planning purposes, you must have capacity at the exact moment you sign legal documents. California courts apply a “sliding scale” – simple documents, such as basic wills, require less capacity than complicated trust arrangements. However, dementia symptoms like memory loss, confusion, and impaired judgment can gradually erode your ability to meet even basic capacity requirements.
The law does not automatically remove your capacity based on a dementia diagnosis alone. Instead, courts look at your functional abilities:
- Can you understand what property you own?
- Do you know who your family members are?
- Can you comprehend how a will or trust affects your assets?
- Who will you distribute your assets to upon your death?
As dementia progresses, these cognitive functions decline, making it increasingly difficult to satisfy legal capacity standards.
What Happens When You Lose Legal Capacity in California
Once a court determines you lack capacity, you cannot create new legal documents like wills, trusts, or powers of attorney. Any existing documents you signed while mentally capable remain valid, but you cannot modify them or create new ones.
Without proper documents in place, your family faces immediate challenges. Banks may freeze your accounts, preventing anyone from paying your bills or accessing funds for your care. Healthcare providers cannot get authorization for treatment decisions from family members. Property sales or refinancing become impossible without court approval.
The Conservatorship Process
When someone with dementia has no estate plan, California families often must petition the court for conservatorship. This legal process appoints someone to make financial and personal care decisions for the incapacitated person.
Conservatorship proceedings usually take three to six months, during which assets remain frozen and important decisions are delayed. Annual reporting requirements and ongoing court supervision add thousands more in costs each year.
The court decides who becomes conservator, and it may not be the person you would have chosen. Family disputes over who should serve as conservator can extend the process and increase costs dramatically. In some cases, the court appoints a professional conservator – a stranger who charges fees from your estate to make decisions about your care and finances.
Healthcare Decision Challenges
Medical decisions become complicated without advance healthcare directives. California law allows family members to make some healthcare decisions, but hospitals and doctors often require specific legal authority for major treatment choices.
Without clear instructions about your care preferences, family members may disagree about treatment options. These disputes can delay necessary care and create lasting family conflicts. Courts may need to intervene in medical decisions, adding more delays and costs.
Long-term care planning becomes particularly challenging. Medicaid qualification strategies that could preserve assets for your spouse or children cannot be implemented once you lack capacity.
The Documents You Need After a Dementia Diagnosis
The steps you take in the weeks and months immediately following a dementia diagnosis can determine whether your family faces years of legal complications or has clear guidance to follow your wishes. You must act now, while you likely still retain the legal capacity needed to create binding estate planning documents.
A dementia diagnosis does not mean you immediately lose decision-making ability. Many people maintain legal capacity for significant periods after their initial diagnosis, especially in the early stages. However, this capacity can decline unpredictably, making immediate action essential to protect your rights and your family’s future.
Several California legal documents can prevent these problems, but only if created while you have mental capacity:
- Revocable Living Trust: Transfers your assets to a trust you control during your lifetime. When you become incapacitated, your chosen successor trustee can immediately manage trust assets without court involvement. This prevents asset freezing and provides continuous management of your finances.
- Financial Power of Attorney: Allows someone you choose to make financial decisions when you cannot. California’s Uniform Power of Attorney Act provides strong protections and clear authority for your agent to act on your behalf.
- Advance Healthcare Directive: Combines a living will with healthcare power of attorney, giving someone authority to make medical decisions according to your stated preferences.
- HIPAA Authorization: Allows your chosen representatives to access medical information and communicate with healthcare providers about your condition and treatment.
Acting Quickly After a Dementia Diagnosis
Time becomes critical after a dementia diagnosis. While you may still have good days and bad days, California law requires that you understand the nature and consequences of legal documents when you sign them.
Many people with early-stage dementia retain legal capacity for months or years after diagnosis. However, this capacity can fluctuate or decline suddenly. Creating estate planning documents as soon as possible after diagnosis protects your options.
If family members question your capacity at the time you sign documents, courts will later examine whether you understood what you were signing. Having medical documentation of your mental state and working with attorneys experienced in capacity issues strengthens the validity of your documents.
