When siblings disagree about a parent's care

Brothers and sisters can look at the same parent and see different things, and the argument that follows is rarely about who cares most. This page sets out whose decision it legally is, how to separate the four things being argued about as one, and what to do next.

Whose decision it is

Who holds the decision, and who does not

Before the practical questions, it helps to know whose decision it is. That turns on whether your parent can weigh up the particular decision in front of them. Find the row that describes your parent, and the one beside it says what the rest of you can do.

Position one

Where your parent is

Your parent can understand the choice, hold it in mind long enough to weigh it up, and say what they want.

Whose decision it is

Your parent, on their own.

What that leaves the rest of you

All of you can give them information, tell them what worries you and disagree with each other. None of you can overrule them, and a choice you think is wrong is still theirs to make. The work here is persuasion rather than authority.

Position two

Where your parent is

Your parent cannot weigh up this particular decision, and made a health and welfare lasting power of attorney while they still could.

Whose decision it is

The attorney or attorneys named in it, deciding in your parent’s best interests.

What that leaves the rest of you

Attorneys appointed "jointly" have to agree with each other before anything can be decided. Appointed "jointly and severally", any one of them can decide alone. Either way, whoever decides has to take the views of anyone caring for your parent, or interested in their welfare, into account.

Position three

Where your parent is

Your parent cannot weigh up this particular decision and there is no lasting power of attorney and no deputy.

Whose decision it is

Whoever is making that decision at the time, usually the social worker, the GP or the hospital team.

What that leaves the rest of you

Every one of you has the right to be asked what you think, and none of you has a casting vote. Being the eldest, living nearest or being listed as next of kin does not carry legal authority on its own. Any of you can apply to the Court of Protection to be appointed as a deputy.

If it cannot be settled

Where your parent is

Your parent cannot weigh up the decision, the family cannot agree, and the decision still has to be made.

Whose decision it is

The Court of Protection, on an application from any of you.

What that leaves the rest of you

The court can make a one-off ruling about where your parent lives or what care they receive, or appoint a deputy to make ongoing decisions. It is slow and it costs money, so it is worth trying mediation and a fresh assessment first.

The Mental Capacity Act 2005 assumes every adult can make their own decisions unless it is shown otherwise, and capacity is judged decision by decision rather than as a general verdict on a person. Your parent can be able to decide about a carer in the mornings and unable to weigh up a decision about surgery the same afternoon. A choice that worries you is not, on its own, evidence that they cannot decide. Can an elderly person be forced into care in the UK? goes through where that line sits.

Where a parent can no longer weigh a decision up, the authority to decide comes from one of two places and no others: an attorney your parent appointed while they still could, or a deputy appointed by the Court of Protection. Making decisions on behalf of someone sets out both routes, and if nobody knows whether your parent made a power of attorney you can search the register held by the Office of the Public Guardian.

Two details settle a lot of family arguments. Where attorneys were appointed "jointly", gov.uk's guidance on choosing attorneys is blunt: they must all agree or they cannot make the decision. And whoever makes a best interests decision has to take into account the views of anyone caring for your parent or interested in their welfare. A brother two hundred miles away and a sister who does the shopping both count.

Four decisions, not one

Separating the four things being argued about as one

Families argue about care as a single question, and it is four. They have different answers, and different people may be right about different ones. Split them up and you no longer have to agree about everything at once.

What help your parent needs

Evidence settles this one rather than opinion: a council assessment, a GP, or a week where each of you writes down what you did.

A question of fact

Where your parent lives

Home with visits, home with a live-in carer, moving in with one of you, or a care home. If your parent can weigh this up, no sibling vote changes it.

Your parent’s decision, while they can make it

Who pays, and out of whose money

Paid for from your parent’s own income and savings, with council help below the capital threshold. Whether any of you contribute is a separate agreement.

Your parent’s money first

Who in the family does what

The visits, the shopping, the appointments, the phone calls. A task list works better here than an argument about commitment.

The hardest one to agree

The fourth question is the one that hurts, and it rarely improves while it is discussed in the abstract. A sibling near your parent carries small interruptions a sibling two hours away does not see, and a sibling further off may be carrying the money or a job they cannot leave. Writing out the week, task by task, gives you something to divide. How can I take care of my elderly parents remotely? has jobs a distant sibling can take on, and the challenges of caring for an elderly parent covers the pressure on whoever does most.

On where your parent lives, care at home or a care home sets both out side by side. On money, can my mum pay me to care for her? covers the tax and council rules where the family is considering paying one sibling for hours they already do.

An outside view

Getting the facts assessed by somebody outside the family

A disagreement between siblings is hard to settle from inside the family, because each of you is arguing from different observations. An assessor with no history with any of you replaces opinion with a written account. All of the following are free.

  1. 1

    Ask the council for a care needs assessment

    Free, and anyone can ask
    A social worker or occupational therapist looks at how your parent manages washing, dressing, cooking and getting about, and writes down what help is needed. A sibling living elsewhere can ask for it.
  2. 2

    Ask for a carer’s assessment for whoever is doing the most

    Separate, and also free
    This looks at the person doing the caring rather than the person cared for, and can lead to a break, practical help or a small budget.
  3. 3

    Ask the GP if capacity or a change in behaviour is the question

    If it applies
    Raise this only where something specific points to it, such as confusion, memory loss or a personality change, not because your parent is choosing something you disagree with.
  4. 4

    Find out whether a power of attorney already exists

    Half an hour
    Families argue for months over decisions a registered power of attorney has already settled. The Office of the Public Guardian keeps a searchable register.

The council's duty to assess is in the Care Act 2014, and section 10 puts it plainly for carers: the duty applies regardless of the council's view of the level of need or of anyone's financial resources. So a family cannot be turned away because somebody assumes your parent has too much money to qualify. The NHS pages on getting a care needs assessment and on carer's assessments explain how to ask, and council funding for care at home and the carer's assessment cover what follows.

Agree one thing before the assessment: who will be there, and who will speak. Four siblings contradicting each other in front of the social worker gives your parent a difficult hour and produces a muddled record. One or two of you, with a written list from the others, is better.

Writing the plan down

Writing a plan the whole family can read

Once you know what your parent needs, put it on one page and send it to everybody. A written plan moves the argument from what each of you believes to what is on the page.

What to put on the page

The week

Who does what

How everyone knows what is happening

When the plan reaches the point where paid help is needed, you can search for carers near you and compare their rates, experience and reviews before anyone commits. Looking is free, and two or three real profiles with real prices can move a stuck conversation, because a named person and an hourly rate are easier to discuss than a vague idea of getting carers in. How many visits a week does my parent need? works the hours out from the tasks.

PrimeCarers is an introductory service rather than an agency, so the family chooses the carer and agrees the visits directly. Before a profile appears, a carer's identity and right to work are checked, an enhanced DBS on the Update Service is confirmed, and they are interviewed online. Training, qualifications and references sit on the profile for the family to check with them.

Paying for it

What paid care costs, and what each of you is agreeing to

Money arguments are hard while the numbers are hypothetical, and easier once they are real. Here is what each kind of care costs.

Hourly visits

What it covers
Washing, dressing, medication, meals and the weekly jobs, on the days you choose
On PrimeCarers
£18 to £25 an hour
Through an agency
£28 to £35 an hour

Overnight care

What it covers
A carer in the house overnight, sleeping and there if needed
On PrimeCarers
£130 to £145 a night
Through an agency
From £150 a night

Live-in care

What it covers
A carer living in the house, covering the day and there at night
On PrimeCarers
From £1,050 a week
Through an agency
About £1,400 a week

PrimeCarers figures are what families pay, with our fee included. Companionship visits run from £15 to £20 an hour. A care home place averages £1,160 a week. Past about 35 hours a week, live-in care costs less than the same hours in visits.

Care is normally paid for out of your parent's own income and savings. In England the council carries out a financial assessment: capital above £23,250 means paying for their own care, capital below £14,250 is disregarded entirely in that calculation, and between the two the council contributes on a sliding scale. Attendance Allowance is worth checking whatever your parent's savings, because it is not means-tested. Attendance Allowance and the care cost calculator are the quickest ways to see where your family sits.

If one sibling is being asked to give up work or hours to cover the care, put a figure on that too. Lost pay, lost pension and the cost of replacing those hours belong in the same conversation. Cancelled and late visits covers what happens when a booked visit does not go ahead, and the guide to care plans covers what a fuller written plan contains.

If you are still stuck

What to do if the family still cannot agree

Some disagreements do not resolve with better information, because they carry twenty or thirty years of other things. The first useful move is to stop trying to win and start protecting your parent's care from the argument.

What tends to help

  • Agreeing a short trial with a review date rather than settling the whole future at once
  • Putting the decision back to your parent wherever they can still make it, and asking them in front of everyone
  • Bringing in a neutral third person: a social worker, an advocate or a mediator
  • Writing to the others afterwards with what you understood was agreed

What tends to make it worse

  • Making arrangements and telling the others afterwards
  • Using your parent to carry messages between the siblings
  • Reading a refusal to help as proof of how somebody feels, when it may be money, health or shame
  • Letting an argument about money delay care your parent needs now

A mediator is a realistic option before anything legal, and worth trying first because it is faster and cheaper than court, and easier to come back from. Mediation is paid for, and the Civil Mediation Council, a charity covering civil, community and family mediation in England and Wales, has a search for accredited mediators. For advice rather than mediation, Age UK has an advice line and local branches, Carers UK supports unpaid carers, and Citizens Advice covers looking after somebody. Age UK's factsheet on arranging for someone to make decisions on your behalf covers powers of attorney and deputyship in full.

If a sibling holding power of attorney is using it against your parent's interests, there is a specific route: report a concern about an attorney or deputy to the Office of the Public Guardian, which investigates. Where your parent lacks capacity and a decision cannot be agreed, the Court of Protection can rule on where they live or what care they receive, and applying to become a deputy is the other route. Both take months, so keep the care going while you use them.

Questions

Questions families ask when siblings disagree

Your parent does, for as long as they can understand and weigh up the particular decision in front of them. That is the starting position under the Mental Capacity Act 2005, and it holds even where the rest of the family is certain they are choosing badly. If your parent can no longer weigh a decision up, the say passes to an attorney under a health and welfare lasting power of attorney, or to a court-appointed deputy.

No. Being the eldest, living nearest or being recorded as next of kin carries no legal authority to decide on somebody else's behalf in England and Wales. Authority comes from a lasting power of attorney your parent made, or from a deputyship granted by the Court of Protection. Without either, decisions for a parent who lacks capacity are made by whoever is making that decision at the time, after consulting the family.

An attorney has to act in your parent's best interests, and that includes taking into account the views of anyone caring for your parent or interested in their welfare. Put your concerns to them in writing so there is a record. If you believe they are acting against your parent's interests, you can report a concern to the Office of the Public Guardian, which can investigate.

It depends how your parent appointed you. Attorneys appointed "jointly" must all agree, and gov.uk states that if they cannot agree they cannot make the decision. Attorneys appointed "jointly and severally" can each act alone. The lasting power of attorney document says which applies. If jointly appointed attorneys are deadlocked, the Court of Protection can decide the point.

Ask the council for a care needs assessment. It is free, anyone can ask for one, and it produces an outside written account of what your parent can and cannot manage, which is harder to argue with than any one sibling's version. Ask for a carer's assessment at the same time for whoever is doing the most.

Price it rather than debate it. Write down the tasks and days, then attach the cost: carers on PrimeCarers charge £18 to £25 an hour with our fee included, against £28 to £35 through an agency. Care is normally paid for out of your parent's own income and savings, so in many families it is not the siblings' money being spent.
