Set up a revocable living trust as soon as possible after an early-stage dementia diagnosis, while the person still understands the decisions. A revocable living trust is a legal arrangement where a person places property in a trust, keeps control during life, and names a successor to manage it if incapacity occurs. A dementia diagnosis alone does not remove the right to sign. Waiting raises the risk that the person will lose the understanding needed to make the document valid.

Why does timing matter so much?
A person can still create or change a revocable trust after diagnosis if they understand their property, family relationships, and the effect of the document when signing. According to Rhodium Law in its guide to dementia and estate planning, that understanding is what preserves legal capacity.
Capacity is judged at the moment of signing, and dementia changes over time. Documents signed earlier, with clear notes from a clinician or attorney about understanding, are harder to challenge later.
What does a funded trust do?
A funded revocable living trust names a successor trustee in advance. If the grantor becomes incapacitated, that person manages the trust assets under the trust terms without court involvement.
The Consumer Financial Protection Bureau explains this role in its explanation of revocable living trusts. That power covers only property actually moved into the trust. Bank accounts, real estate, or investments left outside the trust stay outside the successor trustee's authority.
Why is a trust alone not enough?
Many bills, medical choices, and accounts fall outside a trust. Federal aging experts urge people in the early stage to also prepare or update a will, living will, and durable powers of attorney for health care and finances, as described by the National Institute on Aging in its tips for living alone with early-stage dementia.
Banks may reject informal arrangements, and unfunded plans fail when needed. If capacity is lost without a power of attorney or trust plan, family members must ask a probate court for guardianship or conservatorship, a process that requires an attorney, testimony, and ongoing supervision.
What steps should families take now?
Start with an elder-law attorney who knows local guardianship rules. Bring a list of property, accounts, debts, current wills, powers of attorney, and advance directives.
- Confirm the person understands the trust and related documents before signing.
- Retitle selected bank accounts, real estate, and investments into the trust.
- Pair the trust with financial and health-care powers of attorney and advance directives.
- Review beneficiary forms, titles, and account ownership for gaps.
