Not every trust sale happens after a death. Some of the most delicate sales I handle involve a parent who is still living but can no longer manage their own affairs, often because of dementia or a serious health decline, and who now needs the proceeds of the house to pay for assisted living or memory care. The adult child who was named successor trustee steps in, and suddenly they’re selling the house their parent may still think of as home. The legal mechanics are different from a sale after death, and the tax rules are very different. This article covers both, and it’s part of my guide to selling a house in a trust after a death in Santa Clara County.
Key Takeaways
Summary: When a parent can no longer manage their affairs, the successor trustee can usually sell the house held in their living trust without going to court. Because there’s no step-up while the parent is alive, capital gains, the home sale exclusion, and Medi-Cal planning all need a close look before listing.

From my practice: I sold a home for parents who had moved into a senior community and held the house in their living trust. They were sharp but didn’t want to manage a sale, so their daughter and son-in-law took it on. The family took the photos and keepsakes first, then I had the furniture hauled and donated, and the owners signed by DocuSign with a mobile notary at their community. It sold all cash after 14 days on the market for $1,275,000 and closed 10 days later.
How the Successor Trustee Takes Over
Most revocable living trusts name the parent as the initial trustee and include an incapacity clause spelling out when a successor trustee takes over. A common version requires written statements from one or two licensed physicians that the parent can no longer manage their financial affairs. Once the successor has those, they sign an acceptance of trusteeship, and the trust attorney prepares a Certification of Trust showing the successor’s authority. Title companies will generally want to see the incapacity declarations along with the certification before insuring a sale. I explain the rest of the closing paperwork in what title and escrow need to sell a trust house.
This is often the hardest conversation for families, because it requires a doctor to formally say that Mom or Dad can no longer manage their affairs. I encourage families to approach it with the parent’s primary care physician early and with as much dignity and involvement from the parent as their condition allows.
Trust vs. Power of Attorney
Families often assume the durable power of attorney is the key document. If the house is in the trust, it usually is not. A power of attorney lets the agent act for the parent individually, but it doesn’t generally give authority over assets titled in the trust, unless the trust specifically allows it. If the house was never put in the trust, then the power of attorney may be what allows the sale. My articles on power of attorney and real estate and using a power of attorney to sell a home go through that situation. If neither document works, the family may need a conservatorship, which is slower and involves the court.
The Tax Picture Is Very Different
When a house is sold after death, the heirs get a stepped-up basis and usually owe little or nothing in capital gains. When the house is sold while the parent is alive, the parent’s original basis applies. For a house bought in Los Gatos in 1980 for $150,000 and sold today for $2,400,000, that’s a gain of more than $2 million before improvements and selling costs.
The home sale exclusion under Internal Revenue Code section 121 helps. A single owner can exclude up to $250,000 of gain, and a married couple up to $500,000, if they owned and lived in the home for two of the last five years. There’s also a special rule for exactly this situation: if the owner becomes physically or mentally unable to care for themselves and moves into a licensed care facility, they only need to have lived in the home for one year out of the five, and time in the facility counts toward the use requirement. That can preserve the exclusion for a parent who has been in memory care for several years.
| Los Gatos illustration | Sold while parent is living | Sold after death |
|---|---|---|
| Sale price | $2,400,000 | $2,400,000 |
| Basis | $150,000 plus improvements | About $2,400,000 if sold soon after death |
| Selling costs (illustrative) | ($130,000) | ($130,000) |
| Gain before exclusion | About $2,120,000 | Little or none, often a loss |
| Section 121 exclusion (single owner) | ($250,000) | Not needed |
| Taxable gain | About $1,870,000 | Little or none |
That comparison is why families sometimes explore alternatives to selling, such as renting the house to cover care costs, borrowing against it, or a reverse mortgage, particularly when the parent’s health suggests the time horizon is short. Those are sensitive decisions that need the CPA, the elder law attorney, and the family together, and I never recommend selling or holding without that conversation. My article on ways to unlock home equity covers some of the options.

Medi-Cal and Long-Term Care
For many families the reason to sell is to pay for care. California reinstated a Medi-Cal asset limit for older adults starting January 1, 2026. A primary home is treated very differently from cash under Medi-Cal rules, so selling can change eligibility. If there’s any chance your parent will need Medi-Cal to pay for long-term care, talk to an elder law attorney before listing. My article on what happens to your home when a parent goes on Medi-Cal explains the basics.
A real example: One seller I represented was elderly, living out of the area, and needed the proceeds from her home to pay for her care. A family member handled the sale under her trust and power of attorney from outside the area. We spent $950 on a yard cleanup and deep clean, drew four cash offers in one day, and sold for $428,000, $63,000 over list. When the first buyer cancelled, a backup I’d already signed stepped in the same evening, and the sale stayed on schedule.
Handling the Human Side
Selling a living parent’s home is emotionally different from selling after a death. The parent may ask about the house, want certain things kept, or not fully understand what is happening. In my practice we slow down the cleanout, set aside the items that will make the new room feel like home, photograph the house before anything is moved, and involve the parent in whatever way they can meaningfully participate. As a Certified Senior Advisor, I have learned that the way a move is handled matters as much as the price.
Duties Still Apply
A successor trustee acting for a living parent owes the same duties as after a death, with the parent as the primary beneficiary. That means a fair market price, careful records, and using the proceeds for the parent’s benefit under the trust terms. Other family members who will eventually inherit are often watching closely, so transparency helps here too.

Frequently Asked Questions
Can a successor trustee sell a house while the parent is still alive?
Yes, if the trust’s incapacity provisions have been triggered, usually by written statements from one or two physicians, and the trust gives the trustee power to sell.
Can I use a power of attorney to sell a house held in a trust?
Usually not. A power of attorney generally doesn’t control assets titled in a trust unless the trust allows it. The successor trustee typically handles the sale.
Is there capital gains tax when selling a living parent’s house?
Yes, potentially significant tax, because there’s no stepped-up basis while the parent is alive. The home sale exclusion of up to $250,000 per person may apply.
What if my parent has been in a care facility for years?
If the parent became unable to care for themselves and lived in the home at least one year of the five before the sale, time in a licensed care facility can count toward the two-year use requirement for the home sale exclusion.
Does selling a parent’s house affect Medi-Cal?
It can. California reinstated a Medi-Cal asset limit for older adults in 2026, and a home is treated differently from cash. Consult an elder law attorney before selling.
