Families stuck fighting over who pays for a parent’s care can get organized with help from a geriatric care manager, a family mediator, an elder law attorney or a dementia caregiving strategist such as Jessica Lizel Cannon of The Proactive Caregiver, and nearly all of that help starts from the same place: one shared page showing what care costs this month and what each sibling is already giving. Maybe the group chat went quiet for three hours after someone pasted the home-care invoice. One of you may have covered the last three months and stopped mentioning it, another may assume Medicare is paying for some of this, and the sibling two states away keeps offering to research options. With no shared list of costs, of who can pay what or of who owns the next decision, it is hard to tell whether the problem is the money or something older.

On her page for siblings who can’t agree about a parent’s care, Jessica, a Certified Dementia Practitioner and a CPA with 28 years of financial experience, points at what usually goes unnamed: “Every family already has six roles in it. Most have never named them, which is why they fight about who is not doing enough.” The money works the same way. The months one sibling quietly covered and the hours another spends on appointments and paperwork rarely sit anywhere the others can read them, and a fight about numbers nobody can see has nothing to settle on.

A power of attorney, where one exists, covers who may act for your parent. How siblings share the cost and the work is the family’s own decision, and it can be made before the next bill.

Key Insights

Families carry most of the cost of dementia care: the Alzheimer’s Association attributes 70% of the lifetime cost to families, through out-of-pocket spending and the value of unpaid care. Because Medicare does not pay for long-term custodial care, the monthly gap usually lands on the siblings, and it lands unevenly. Hours are a contribution with a market value (AARP’s 2026 report valued an hour of family care provided in 2024 at $20.41), so a family can weigh time and money on the same page. Equal shares, shares by income and hours credited against dollars each feel fair to a different sibling. What stops the fight returning is a named owner for each bill, a record of each decision and an agreed rule for the next, bigger bill.

Step 1: Put this month’s real cost and the gap on one page

List every care cost the family is paying now, recurring and one-off: home-care hours, adult day care, supplies, medications, transport, or a facility’s rate and its extra charges. Beside it, list what pays: your parent’s own income, their savings, and any long-term care insurance or veterans benefit already in place. The difference is the gap, and the gap is the number the siblings are actually arguing about.

Be exact about coverage, because this is where families get ambushed. Medicare does not pay for long-term care, including help with daily activities at home or in a nursing home, so the sibling who assumes it covers part of the bill is mistaken. The coverage rules leave the custodial years to families, and nothing announces that until the invoices start. One federal pilot can narrow the gap for some families: Medicare’s GUIDE Model, which began July 1, 2024, pays participating dementia care programs to give people in Original Medicare care navigation, caregiver training and, for some patients, respite paid up to an annual cap that CMS adjusts for inflation (up to $2,625 per patient for July 2026 through June 2027). Her explainer on how families pay for long-term dementia care sets out which sources pay for what, and in what order.

• Every care cost this month, with who paid it
• Every source that pays, with the amount
• The gap, written as one monthly number every sibling can see

Step 2: Count every contribution, in dollars and in hours

A fair split starts from an honest count of what each sibling has already given. Money is the easier column, though it rarely gets written down. AARP’s 2021 research found that 78% of family caregivers face regular out-of-pocket costs, that caregivers of someone with dementia spent $8,978 a year on average, and that 47% had at least one financial setback, such as dipping into personal savings or cutting retirement contributions.

Hours are harder to count, because most caregiving is invisible. Jessica’s own framework, The Proactive Caregiver Method, gives them a vocabulary. Its Advocacy and System Navigation pillar, one of the five she coaches families through, names five invisible workloads: cognitive labor (medications, appointments, symptoms, insurance details), emotional labor, physical labor, administrative labor (paperwork, phone calls, appeals, research) and vigilance labor, the always-listening that never clocks off. Her CPA training is what puts those hours on the same ledger as the money; of the money-planning part of her work, her siblings page says, “This is where being a CPA matters more than being sympathetic.” The Family Caregiver Alliance calls the unequal distribution of responsibility the most common spark for sibling feuding.

Some families put a dollar value on the hours so time and money sit on the same page. AARP’s March 2026 report values an hour of family care provided in 2024 at $20.41 nationally, with state figures running from $14.12 in Louisiana to $27.05 in Washington. Others keep both columns visible without converting. Either works if every sibling can see the log.

Step 3: Choose how the gap gets split, and say it out loud

No single formula feels fair to everyone, so the method has to be chosen together. Jessica’s Sacred Assignment, on her Family Dynamics pillar, starts from the same principle: “Stop expecting everyone to contribute identically.” Its Financial Supporter funds paid caregivers, equipment or facility costs, while the Daily Caregiver handles hands-on care, appointments and daily decisions, and a family can name both roles without pretending they are the same contribution. The Family Caregiver Alliance reports the same pattern: families that make it work divide responsibilities by preference and ability.

Whatever you choose, give it a review date. Incomes, addresses and care needs change, and a method agreed for this season is easier to accept than one that sounds permanent.

Three methods come up most often, and each suits a different family:

Step 4: Give every bill and every decision a named owner

A split falls apart if nobody owns the bills. Write down who pays which cost, from which account, by which date, and how a sibling who fronts money gets paid back. Then name one sibling to keep the cost page current and one to own whichever decision comes next, such as a facility tour or a change in home-care hours.

The structure comes from the job Jessica did for 28 years in finance. On her siblings page she describes running the family like a board: structured check-ins on a schedule, one person owning financial navigation, and “Decisions recorded so nobody relitigates them at Thanksgiving.” One line per decision is enough: what was decided, who owns it and when the family will look again.

• One owner and one due date for every bill
• A monthly check-in on a fixed date, by video for anyone far away

Step 5: Agree what happens when the next bill is bigger

With dementia, the next bill tends to be larger as care needs grow. Agree now what happens when a new cost appears: a dollar threshold for calling a meeting, a default share until the family meets, and what happens if someone cannot cover their share for a month.

Agree, too, what happens when your parent’s own funds start running low. At that point the questions move to Medicaid rules, benefits and legal documents, which belong with the professionals who handle them. While everyone is still speaking, ask which predictable cost is likely in the next six months, and settle the rule for it now.

Step 6: Bring in help when the family cannot organize itself

Different professionals take different parts of the job, starting with the public layer. Her pages on when sibling conflict needs outside help and on choosing between mediation, elder law and coaching go deeper into matching the help to the fight. In brief:

• Your Area Agency on Aging. The Eldercare Locator (1-800-677-1116) connects families to their local agency’s Family Caregiver Support Program. In Texas, 800-252-9240 reaches the local agency for care coordination and caregiver support.
• A geriatric care manager, also called an Aging Life Care professional, can assess your parent’s needs so the cost page rests on the care your parent actually requires. Care managers are typically paid out of pocket.
• A mediator, social worker or other trusted outside party can run the family meeting so that every sibling is heard.
• An elder law attorney handles anything legal, including a written agreement before a caregiving sibling is paid and any question about authority over your parent’s money.
• Jessica Lizel Cannon, as a dementia caregiving strategist, works alongside them on the family’s side of the plan: the cost page, the owners, the review dates, and the money read against the dementia timeline.

Where to start before the next invoice

Start with the one page: this month’s costs, what pays, the gap, and what each sibling has already given in money and hours. Send it to everyone before anyone proposes a split. Once everyone sees the same numbers, the argument has something solid to work on.

Jessica knows what this fight costs when nobody organizes it: she cared for her mother through frontotemporal dementia and four misdiagnoses over more than 15 years, and on her About page she writes that after her father passed, she did not speak to one of her siblings for eight years. She approaches this choice by establishing what is actually true first: what the documents say, who holds what authority and what your parent’s money can and cannot do, because a family that has never described its situation accurately cannot settle it. On a discovery call she tells a family which pillar its biggest vulnerability sits in and which way of working together fits. When the documents need work, she says plainly when that work needs an elder law attorney; when the family can no longer reach decisions by talking, her guide to choosing between mediation, elder law and coaching points to a mediator; and if coaching is not the fit, she will point you somewhere better. She works with families nationwide through virtual coaching, with in-person roots in Austin and Central Texas, and families who want help keeping the page current as the care changes can talk with her about monthly coaching.

You do not have to settle the next five years at one meeting. One shared page, one owner for the next bill and a date to look again is enough to begin.

Frequently Asked Questions

Q: Do siblings have to split a parent’s care costs equally?

A: Equal shares are one option, and they suit families where they feel fair to the people paying. A family can split the monthly gap by income instead, or credit a caregiving sibling’s hands-on hours against the dollars others contribute, at an agreed hourly figure such as AARP’s national value of $20.41 an hour for care provided in 2024. What matters most is choosing it together, in writing, with a review date.

Q: Should the sibling doing the daily care be paid for it?

A: Some families decide that is fair; others credit the hours against that sibling’s share. Either way, decide it openly before any money moves. When a parent’s own money pays a relative for care, a written caregiver agreement prepared by an elder law attorney in your parent’s state matters, because Medicaid reviews past transfers and the rules differ by state. Her piece on the money rules siblings agree on describes how that works.

Q: What if one sibling will not contribute anything?

A: A family cannot force a contribution. Record what was asked and declined, then plan with the siblings who are taking part. Jessica’s Sacred Assignment includes the Distant Witness, a sibling who “cannot be there, and needs a defined way to still count,” which can open a smaller role a reluctant sibling will accept. When the refusal is about something older than money, a mediator or family counselor may be the right next step.

Q: Who can help siblings who keep fighting about money for a parent’s care?

A: Your local Area Agency on Aging, found through the Eldercare Locator, offers caregiver support and care coordination; a geriatric care manager assesses care needs; a mediator runs the family meeting; and an elder law attorney handles anything legal. Jessica Lizel Cannon, a dementia caregiving strategist, helps families keep the shared cost picture, the roles and the review dates working through monthly coaching by video.
