Split caregiving costs between siblings in three steps. First, separate your parent's own money, which pays for their care, from costs the children choose to cover. Second, pick one split method for the children's share: equal, by income, time-for-money, or a fixed monthly pool. Third, write it on one page with a spending limit, a receipt rule and a review date.
The deposit is due, someone has to book movers, and your brother just asked whether "we're all splitting this." Nobody has said what "this" includes, or whether the hours your sister spends at Mom's count for anything. That's how a cost question turns into a family feud.
This post covers how to decide who pays what. The mechanics of logging receipts are in how to track caregiving expenses as a family, and the ways parents typically fund assisted living are in how families pay for assisted living.
Step 1: sort every cost into one of three buckets
Before anyone splits anything, decide whose money each cost should come from. Money fights between siblings tend to start when these buckets get mixed.
| Bucket | Examples | Who decides |
|---|---|---|
| Your parent's money | Monthly assisted living fee, community fee, medications, their own bills | Your parent, or the person they gave legal authority to |
| Costs the children agree to share | Flights to help with the move, movers or a clean-out crew, supplies, a gap in the monthly fee | The siblings, by agreement |
| Time | Touring, packing, paperwork, visits, the weekly family call | The siblings, by agreement |
Your parent's money pays for your parent's care first, as far as it goes, and it stays in their name. The Consumer Financial Protection Bureau's guide for agents under a power of attorney says to keep the parent's money separate from yours, pay their expenses from their funds, and avoid joint accounts. If you do pay something for your parent from your own pocket, the guide says to keep receipts and a record of why, what and when you paid yourself back.
The children's share is where you need a split. Out-of-pocket costs add up. AARP says family caregivers pay on average roughly $7,200 a year out of pocket (2025). In the AARP and National Alliance for Caregiving 2025 survey series, 44% of caregivers of adults 50 and older reported at least one negative financial impact, such as taking on debt or stopping saving.
Step 2: choose a split method
There's no legal formula for how siblings share voluntary costs. Pick the method your family will actually stick to, and use it for everything in the second bucket.
| Method | How it works | Works well when | Watch out for |
|---|---|---|---|
| Equal shares | Every shared cost is divided by the number of siblings | Incomes are similar and time is shared evenly | It feels unfair to the sibling doing the hands-on work |
| By income | Each sibling pays a percentage agreed in advance, roughly matching what they can afford | Incomes differ a lot | Requires some openness about money; agree percentages once, not per bill |
| Time-for-money | Siblings who give more hours pay a smaller share | One sibling lives nearby and does most on-site work | Agree in advance how much time offsets how much money |
| Monthly pool | Each sibling puts a fixed amount into a separate family fund; costs are paid from it | Costs are frequent and small | Keep it separate from your parent's accounts and log every payment |
Family Caregiver Alliance's family meeting guide puts money on the agenda with plain questions: how much will it cost, how much work can family members afford to miss, and what outside financial help might be available. Answer those before you pick a method.
A hypothetical example: three siblings agree to split shared costs 50/30/20 by income. The sister who lives near Dad does most of the move-week work, so the family agrees her share drops to 10%, and the other two cover the difference. Everyone knows the numbers before the first invoice arrives.
Does time count as a contribution?
Many families decide it does, and saying so openly defuses a lot of resentment. FCA's fact sheet on caregiving with siblings suggests asking each sibling what they can contribute "in time or money." The same sheet warns that when one sibling takes on caregiving, the family needs to spell out what that person will do and whether there will be compensation.
The simplest way to count time is to make it visible. List the tasks of the move with rough hours, then split the hours in proportion to what each sibling can give. Our guide to splitting the work with siblings explains the method, and the free sibling task splitter calculates it. Once hours are on the table, it's easier to agree that the sibling carrying 30 hours pays less than the one carrying 5.
You don't need to put a dollar value on an hour. You can simply agree on a lower money share for the person doing the most on-site work.
Keep hours and money in one place
The Complete version of Parent Move Plan includes a Fair Share tab that splits the move's work in hours, a Team tab that notes who lives nearby, and a shared costs log that records who paid what. Siblings see the same numbers instead of keeping separate tallies.
Build your plan in 2 minutesStep 3: write a one-page cost agreement
A short written agreement prevents most future arguments. It's a family document, not a legal contract. Include:
- What counts as a shared cost. List categories: travel for the move, movers, clean-out, supplies, and anything else you agree on. Say what doesn't count, such as each sibling's own visits after the move.
- The split method, with the percentages or amounts.
- A spending limit. Anyone can spend up to an agreed amount without asking; above it, get a yes in the family chat first.
- The receipt rule. Photo of every receipt into one shared folder or log within a week.
- Settle-up timing. For example, balances are evened out on the first of each month.
- Your parent's money. Who holds authority over it, and a note that shared family costs stay separate from it.
- A review date, such as 30 days after move-in, when costs usually change.
Then use the log from tracking caregiving expenses to record every payment against this agreement.
Paying a sibling, or topping up the monthly fee
Two situations need more than a family agreement, and both are worth a conversation with an elder law attorney before any money moves.
Paying a sibling for care out of your parent's money. The CFPB guide says an agent must act only in the parent's best interest and keep detailed records, which gets complicated when the agent or a sibling is the one being paid. Questions to ask an attorney: Should there be a written caregiver agreement? How would payments be documented? Could they affect benefits your parent may apply for later, such as Medicaid?
Siblings helping with the monthly fee. CareScout's 2025 Cost of Care Survey puts the national median for assisted living at $6,200 a month, so even a partial top-up is a long-term commitment. Before promising one, ask: How long can each of us sustain this? What happens if one of us stops? How would the payments be made, and does that matter for any benefits or taxes? A tax professional can help with the last question; also see whether assisted living is tax deductible.
This article explains options families commonly discuss. It isn't legal, tax or financial advice. For decisions involving your parent's money or benefits, talk to an elder law attorney or a tax professional.
How to bring it up
Raise money early, in a planned conversation, not in the middle of an argument about a specific bill. FCA's sibling fact sheet advises asking directly and specifically, and warns that guilt makes people defensive.
What to say:
"Before the bills start, can we agree how we'll handle costs? Mom's money pays for her care. For things like the movers and flights, I'd suggest we split by income, and since Dana is doing most of the packing, her share is smaller. I'll put it on one page, and we look at it again a month after move-in. What would you change?"
If a sibling won't engage at all, see what to say to a sibling who doesn't help.
Frequently asked questions
Do siblings have to split the cost of a parent's assisted living equally?
No rule requires an equal split between siblings. Some families split in proportion to income, or let the sibling who gives more time pay less. Whatever you choose, write it down so nobody keeps a private tally.
Should the sibling who does the caregiving pay less?
Some families decide that time counts as a contribution, so the sibling doing most of the hands-on work pays a smaller share or nothing. If you're considering paying a sibling for care out of your parent's money, talk to an elder law attorney first.
What if one sibling can't afford to contribute?
Ask for time instead of money, such as owning the paperwork, the mover quotes or the weekly family call. Log those hours next to the money so both kinds of contribution are visible.
Should we open a joint account for our parent's care costs?
Keep your parent's money in your parent's name and separate from anyone else's. The Consumer Financial Protection Bureau tells agents under a power of attorney to avoid joint accounts and to get legal advice before changing an existing one. A separate log of what siblings contribute avoids mixing the two.
