Facing a life-changing health event can make everything feel urgent. We understand this. We write from experience and want to give clear, calm steps you can use right away.
This guide is about control, not pessimism. It explains simple actions: your Will, who can step in to help, and how your estate is handled if you die. You do not need legal training to follow it.
Start by gathering the right information while you still have the time and headspace. Small tasks now save stress later for your family.
We present a practical, UK-focused how-to in stages. Expect checklists for the first week, notes on mental capacity, Wills and intestacy, children and guardianship, money management, benefits and probate preparation.
Think of this as a living plan. You can update it as treatment, care needs and family changes happen. We are here as your supportive team to protect your loved ones and reduce worry.
Key Takeaways
- Act now: small steps save time and stress later.
- Gather clear information early while you can.
- Wills, guardianship and money notes are core elements.
- This is a living plan — update for changes in care or family.
- We are your supportive team, focused on protecting your family.
What a serious illness diagnosis changes for your estate, finances and family decisions
A new medical reality can quickly alter income, care needs and who takes key decisions.
What typically shifts: income and work patterns may change. Benefits and treatment choices become part of daily planning. Family members often step in for day-to-day decisions.
Why act now: while you have clear capacity, you can record your wishes and name who should help. This reduces guesswork and family stress later.
- Connect care priorities with practical finances so money does not become the loudest voice.
- Coordinate services — GP, hospital teams and social care assessments — to make support clearer.
- Even small steps this week can protect your future and ease pressure on those who help.
Example: one partner becomes unwell and has already named who handles bills and care. Early choices prevent delays and disputes.
| Area | Common change | Quick action |
|---|---|---|
| Income | Reduced earnings or stopped work | Record sources and contact benefits support |
| Decisions | Family makes day-to-day choices | Name trusted decision-makers and document wishes |
| Care | New services and assessments | List GPs, hospital contacts and social care teams |

estate planning after receiving a serious illness diagnosis uk: a practical first-week checklist
A short, organised checklist in the days ahead gives you control and practical help for the people who support you.
Gather key documents and information
What to collect first: bank details, mortgage and property paperwork, pension letters, insurance policies and any existing Will or letter of wishes.
Create a one-page snapshot that lists accounts, regular bills and where each document is kept. This makes money and document checks quick for whoever needs them.
List the people who may need to make decisions
Write down who you want to step in: partner, adult children, close friends or professional contacts.
Note what each person could do — pay bills, contact services, or speak to medical teams. Keep contact details with the main folder.
Record immediate care wishes and what matters most
Say plainly what you want: home or hospital preferences, who to call first and any personal requests that matter to you.
Make sure the information uses clear file names and is kept in one known place. Share copies with the people you trust.
- Keep paperwork simple and labelled.
- Give one trusted person the folder location.
- Update the snapshot when details change.
“Having documents in one place meant Mum’s insurer was contacted the same afternoon and pension nominees were checked within days.”
This checklist speeds up urgent admin and helps services act faster. For most people, one tidy folder and a short note of wishes solve the immediate tasks and reduce stress for everyone involved.
Understand mental capacity and who can make decisions if you cannot
When thinking ahead, it helps to be clear about who can step in if you cannot speak for yourself.
Mental capacity means you can understand information, weigh options and communicate a choice. We use the phrase mental capacity to describe that ability. If capacity changes, some legal document choices may no longer be valid.
What this looks like in practice
- You may struggle when tired, stressed or on strong medication.
- Capacity can vary by decision — someone may decide about daily care but not complex finances.
- If you lose capacity, you need someone authorised to make decisions for you.
Choosing someone you trust
Pick a person you know will act as you would. Look for honesty, calm and practical sense. We call this someone else who can make decisions on your behalf.
Health choices and finances choices are different. You can grant separate powers. For financial authority, many people use a power of attorney. Arrange this while you still have capacity.
Talk clearly about limits: what you want, what you do not want, and who else they should consult. Write notes after the chat and keep them with your key papers. Get professional advice early if family links, business interests or pressure from others could complicate matters.
Make or update your Will to avoid the rules of intestacy
Without a current Will, the law decides who receives your property and money. That process is called the rules intestacy and it applies when a Will is missing or invalid.
Intestacy aims to protect a spouse or civil partner and any children. It covers legally adopted children too.
But there are clear gaps. Unmarried partners and step-children may receive nothing under the rules intestacy. That can leave your possessions with people you did not choose.
- What a Will does: names who inherits your estate, who handles paperwork and who receives specific gifts.
- What can go wrong: intestacy can pass property or money to distant relatives, creating delay and disputes.
- Probate note: those who inherit under intestacy usually manage probate and administration themselves.
If you have no living relatives, your estate can pass to the Crown. The office responsible differs across the nations:
| Nation | Responsible office |
|---|---|
| England & Wales | Treasury Solicitor |
| Scotland | King’s and Lord Treasurer’s Remembrancer |
| Northern Ireland | Crown Solicitor’s Office |
Review any Will you already have. Check executors, guardians for children, and whether gifts reflect your current wishes.
Get advice if you have a second marriage, blended family or want to leave money to friends or chosen family. We can help you make choices that match your life and protect the people you care about.
Plan for children and guardianship in a way the courts can act on
Naming who should care for your children gives clear direction to your family and to the courts. A Will is the best legal document for this choice if you are able to sign one.
Appointing a guardian and what responsibility means
A Will can say who you want to look after your children. If that person agrees, they gain legal rights and responsibilities to care for them.
That role covers: daily care, schooling decisions and general welfare. It does not automatically pass on money unless you name trustees.
Age rules across the nations
“Young children” usually means under 16 in Scotland.
In England, Wales and Northern Ireland the cut-off is under 18. This difference matters when you choose who will step in.
Common situations where planning is vital
- Separated parents where responsibility can be challenged.
- Blended family households or when a step-parent cares but lacks legal status.
- When one parent is the only living parent or the other lives abroad.
What if both parents die without a Will?
If no Will names a guardian, the court decides. This can take time and, in the meantime, children may enter foster care.
Planning avoids that delay. It tells the court your clear wishes and helps keep children with people you trust.
“When parents were separated, naming a guardian in the Will made the court decision straightforward and kept the children with their aunt.” — example
For more detail on how a named guardian works, see our note on what happens if your Will doesn’t specify a. Choose a person who can provide stable care and write short notes explaining your reasons.
| Issue | Who may act | How to fix it now |
|---|---|---|
| Other parent | Usually automatic unless unsuited | Name a backup guardian in your Will |
| Step-parent | No automatic responsibility | Grant parental responsibility or name them in the Will |
| Both parents die | Court decides | Name guardians and trustees clearly |
Put day-to-day money management in place for when you need help
Practical money arrangements let those who help act quickly and securely.
Two simple choices are common: share a joint bank account or give a third-party mandate. Both let someone else pay bills and manage routine spending.
Joint bank accounts — what you need to know
Both holders can withdraw and make payments. Both are also liable for any overdraft.
If one person dies, the other usually inherits the account balance and any overdraft responsibility. This makes life easier for day-to-day cash, but it may complicate the wider estate later.
Scotland difference
In Scotland, money you paid into a joint account can sometimes still be treated as your own on death. If you can prove you added funds, that part may form part of your estate.
Third-party mandates — limits and bank rules
A mandate keeps the account in your name while authorising someone else to transact. Banks usually ask for a signed form and ID. They may refuse or set conditions.
- Mandates should stop if you lose capacity or die. The nominated person must tell the bank if your condition changes.
- Make sure there is a clear bills list, direct debit note and a short written document explaining how you run the household.
- Choose someone else who is trustworthy and keep records of transactions to avoid disputes.

Arrange support for benefits and income if you cannot manage claims yourself
Simple steps now can let a trusted person handle benefit collection while you focus on care.
We explain the difference between someone who simply collects payments and someone who manages benefit claims for you.
How to let someone collect your state benefits safely
You can ask a trusted person to collect payments. If money is paid into your bank or building society account, banks may accept a third‑party mandate so another person can withdraw on your behalf.
Using a mandate for benefits paid into a bank or building society account
Ask the bank what paperwork they need and keep written confirmation. Make sure the mandate states when it should stop, for example if your condition changes or you regain control.
Post Office card account collections and who to contact
If payments use a Post Office card account, speak to your local Post Office about authorised collection. Otherwise contact the office that handles payments: Jobcentre Plus in Great Britain or the Jobs and Benefits office in Northern Ireland.
Appointees for managing benefit claims: responsibilities and risks of overpayment
You can nominate an appointee to manage claims and speak to benefits offices. They must keep information accurate and notify changes.
- An appointee deals with claims and keeps records.
- They may be asked to repay overpayments if details were not kept up to date.
- Keep a paper trail: dates, names, and confirmation letters saved with your other key documents.
“When treatment meant hospital stays, naming an appointee kept our household income steady.” — example
If forms feel overwhelming, use a support line from DWP or trusted advisers for clear advice. We can guide you through the steps and the service options that suit your needs.
Protect property, possessions and probate paperwork so your estate is easier to deal with
A tidy record of property and valuables makes a difficult time far easier for those who must act.
Start by creating a clear inventory of your main property, high-value possessions and everyday items. Say where each item is kept and note any proof of ownership. Keep entries short. Add photos or receipts where useful.
Why this helps: a quick list turns a long search into a simple task for the person sorting affairs. It saves time and reduces risk of family dispute.
Create a simple structure for the inventory
- Address and title information for each property you own or share.
- List valuables and possessions with location and proof (warranties, receipts).
- Digital accounts and passwords — note the place where they are stored.
- Who has copies of key paperwork and how to access them.
Reduce probate delays and flag complications early
Document where probate paperwork lives. Name the person with the main copy. Note any shared ownership or unusual arrangements that may form part of the estate.
| Issue | What to list | Quick action |
|---|---|---|
| Joint ownership | Property title, bank accounts, share percentages | Note deeds and contact details for co-owners |
| Missing papers | Proof gaps for possessions or payments | Photograph items and record purchase details |
| Potential dispute | Unclear gifts, verbal promises, family claims | Write short notes explaining your wishes and witnesses |
Make sure trusted people know the place of the inventory. Keep it secure. Update it for any changes in minutes, not hours. A small effort now can save months of work for your family.
Conclusion
A few straightforward choices today can give your family calm, practical instructions for care and money matters.
We recommend three quick first steps: use the first-week checklist, have one clear conversation with the people you trust, and book a meeting to start legal paperwork. These actions protect your wishes and make future decisions easier.
Planning helps if energy is limited. It keeps finances and daily admin simple. One small example of a viable plan: one folder for documents, one conversation about wishes, and one appointment with a service provider or solicitor.
Make sure you set powers while you can. A power attorney and a valid Will give others the legal authority to act. The right approach can differ across the UK, including Northern Ireland, so get tailored support.
