Siblings sharing the costs of caring for a parent

When a parent starts to need help, the costs arrive a little at a time: medication, a carer a few hours a week, appointments, a taxi, a repair. Usually the children share them, and usually one of them ends up paying more than the others realise. Not out of bad faith, but because nobody is keeping track.

This guide is for siblings who want to share those costs openly, so money does not become one more difficult subject at a time that is already hard.

#Why keep a record

• Because memory is not enough. Three months of prescriptions, lifts and small purchases cannot be rebuilt from memory.
• Because whoever lives closest usually pays more. The sibling nearby pays for the taxi, picks up the urgent prescription, covers the carer's week. Without a record, that effort is invisible.
• Because it prevents arguments later. A written record of who put in what, and what it was spent on, is the best way to avoid doubts down the line, when emotions run high.

#Start with a conversation

Before any spreadsheet or app, sit down together (or get on a video call) and agree on:

• Which costs are shared. For example: healthcare, the carer, food and your parent's bills. And which are not: travel to visit, which each of you covers.
• How to split them. Equal shares is simplest, but not always fairest. Some families split according to income; others recognise that a sibling who gives hours of care is contributing in another way and puts in less money. There is no right answer, but there does need to be an agreed one.
• Whether to have a shared fund. Many families set up a fund each sibling pays into monthly, and the costs come out of it. It is the tidiest option. We cover it in how to run a shared kitty.
• Who manages it. Usually the sibling who lives closest. Managing does not mean deciding alone: everyone sees the record.

#What to write down

For each expense, at least:

• the date and amount, in the currency it was paid in;
• what it was: "October prescriptions", "carer, week 2";
• who paid or which account it came from;
• a tag for the kind of cost: health, carer, food, bills, paperwork.

And for each contribution to the fund, who made it and when. With that, any of you can see at any time how much was spent, on what, and how much each person put in.

Keep important receipts (medical bills, the carer's invoices) in a shared folder too. The record says what happened; the receipt backs it up.

#Review it together, without blame

A short monthly check helps a lot: how much was spent, whether anyone put in less than agreed, whether a big cost is coming up. Talk about the numbers, not the people. The record is there so nobody has to justify themselves.

If legal or inheritance questions come up at some point, a clear record helps, but it is no substitute for professional advice.

#Frequently asked questions

#Is splitting 50/50 fair if one sibling does the caring?

Not always. Time spent caring is a real contribution, and many families reduce the money that sibling puts in. What matters is that everyone agrees and it is written down.

#Who should keep the records?

Usually the sibling who manages day-to-day costs, but everyone should be able to see them. A shared record means nobody has to take anyone's word for it.

#What if a sibling lives abroad?

They can contribute in their own currency. Keep a separate balance per currency rather than converting it, as we explain in how to track shared money in two currencies.

#Doing it in Contamos

Contamos is a shared ledger for any group that shares money, and a group of siblings is exactly that:

• you create a team and invite your siblings; everyone sees the same numbers and who recorded each transaction;
• one account is the fund for your parent's costs; if a sibling lives abroad and contributes in another currency, each currency keeps its own balance;
• each contribution is income, and each expense is recorded with tags such as "health" or "carer";
• you can export everything to CSV when the family wants a summary.

Contamos does not connect to any bank or work out what each of you owes: it keeps a clear, shared record of what you enter. It is free to start, and the quickstart takes a few minutes.
