Estate Planning Checklist UK: The Step-by-Step Guide to Protecting Your Family (Wills, LPAs & More)

If you have been thinking, “We really should get our affairs in order,” you are not alone and you don’t need to be wealthy to benefit from estate planning.

An estate planning checklist is a simple, practical set of steps that helps protect your family if you die or lose mental capacity. For most UK families, the essentials are: a valid Will, both types of Lasting Power of Attorney (LPA), up-to-date pension and insurance nominations and a clear plan for children, property and key documents.

Use the checklist below to prioritise what matters most for your situation, avoid common mistakes, and feel confident that your plan will actually work when your family needs it.

The UK Estate Planning Checklist: 12 steps you can work through

This checklist is designed to be scannable, practical, and easy to action. You do not need to do everything in one weekend but you do want to start with the steps that close your biggest risk gaps.

1) Write or review your Will

Your Will sets out:

·       who inherits your estate (money, property, possessions)

·       who looks after children under 18 (guardians)

·       who manages the process (executors)

Quick prompts

·       Have you named executors you trust to actually do the admin?

·       Do you have a clear plan for children if something happens to you?

·       Does the Will reflect your life now (new home, new relationship, divorce, new children)?

Soteria Estate Planning note (why this matters): A Will isn’t just a form the wording needs to match real life. A boutique approach like Soteria’s helps you avoid the “template trap” where something looks fine but does not do what you think it does.

2) Put LPAs in place (Property & Financial + Health & Welfare)

LPAs are often the missing piece. A Will only matters after death. LPAs protect you while you are alive if you can’t make decisions.

You will normally want both:

·       Property & Financial Affairs LPA (banking, bills, property)

·       Health & Welfare LPA (care decisions, medical treatment, living arrangements)

Quick prompts

·       Who do you trust to act in your best interests under pressure?

·       Do you want attorneys to act together or separately?

·       Have you named replacement attorneys?

3) Choose guardians and trustees for children (if applicable)

This is where many parents assume “family will sort it out.” They might but your Will is where you can make it clear.

Guardians look after the children day-to-day.
Trustees manage money and assets for them until an age you choose.

Quick prompts

·       Have you spoken to the guardians you want to appoint?

·       Are the right people in place to manage money sensibly for your children?

·       If you have a blended family, is it crystal clear who should do what?

4) Check how your home is owned (especially couples and blended families)

How your property is owned can affect what your Will can do.

Quick prompts

·       Do you own the property jointly with a partner?

·       If one of you dies, do you want your share to pass automatically to the other or to be protected for children?

·       In a second marriage, do you want a plan that protects both your spouse and your children?

You do not need to become a legal expert here you just want to make sure your estate plan matches how things are actually held.

5) Update pension and life insurance nominations

Many people assume their Will controls everything but it often doesn’t.

Pensions and life insurance can be paid based on nominations rather than the Will so check these are current.

Quick prompts

·       Are your beneficiaries up to date after marriage, divorce or a new partner?

·       Would the money go to the people you intend today?

6) Create a one-page asset list

This is one of the simplest things you can do and one of the most useful.

Include:

·       bank accounts, savings, ISAs

·       pensions

·       property details

·       investments

·       business interests

·       valuable items (if relevant)

Tip: Keep it high-level. Your executor needs a map, not your entire filing cabinet.

7) List debts and ongoing household commitments

This avoids confusion and delays later.

Include:

·       mortgage and loans

·       credit cards

·       utilities and council tax

·       subscriptions

·       any regular financial obligations

8) Write a “family instructions” note

This isn’t a legal document, it is a practical one.

Include:

·       who to contact (close family, employer, financial adviser if applicable)

·       key account details location (not passwords in the note itself)

·       funeral wishes (if you have them)

·       where the Will and LPAs are stored

·       what you’d want your family to prioritise

This can reduce stress in the first 48 hours after something happens when nobody wants to be hunting for paperwork.

9) Make a plan for care decisions and “what if I lose capacity?”

This is where LPAs become very real.

Quick prompts

·       If you couldn’t make decisions, what would matter most to you? (staying at home, staying near family, specific care preferences)

·       Who would speak for you calmly and confidently?

·       Are there family dynamics that could cause conflict?

Even a short conversation and a clear plan here can prevent a lot of chaos later.

10) Consider fairness, gifts, and blended-family outcomes

This is often where people get stuck because it is emotional.

Quick prompts

·       Do you want everything split equally or fairly based on needs?

·       Are there stepchildren or children from previous relationships?

·       Do you want to provide for a spouse but protect children’s inheritance too?

The goal isn’t to make it complicated. It is to make it clear.

11) Sort your digital life

Your “estate” now includes digital access.

Consider:

·       where your password manager is stored (and who could access it in an emergency)

·       what you want to happen to social media accounts

·       key devices and important files (family photos, business documents)

12) Store everything safely and tell the right people

A perfect plan that no one can find causes delays at the worst time.

Quick prompts

·       Where is your original Will?

·       Who knows where it is?

·       Do your attorneys know how to access the LPA details when needed?

·       Is there a backup plan if the main attorney is unavailable?

What should you do first: the Will, the LPAs, or the checklist?

If you can do both a Will and LPAs, brilliant that closes the biggest gaps.

If you are prioritising, use this quick guide:

Start with a Will if:

·       you have children under 18

·       you are unmarried but in a long-term relationship

·       you have a property and dependants

·       your current Will is outdated (marriage, divorce, new baby, new home)

Start with LPAs if:

·       you are supporting ageing parents

·       you have health concerns or a family history of dementia

·       you’re the person who manages the finances

·       you want protection if illness or an accident happens unexpectedly

Do both together if:

·       you have a blended family

·       you are divorced with children

·       you have complicated dynamics where clarity reduces conflict

This is exactly where Soteria Estate Planning helps most: taking what feels overwhelming and turning it into a clear, calm plan you can work through step-by-step without a rushed, impersonal experience.

Estate planning checklist by family type

Married couple with young children

Your priorities

·       Will with guardians and trustees

·       both LPAs (so the other parent can act if needed)

·       up-to-date pension and life cover nominations

·       clear storage and “where to find everything” note

Common mistake

·       assuming “my spouse can just do it” especially for finances and care decisions.

Unmarried partners

Your priorities

·       Will (this is often urgent)

·       LPAs (so your partner can act for you)

·       property ownership check

·       nominations on pensions/insurance

Common mistake

·       assuming long-term partners are treated like spouses automatically.

Divorced parent

Your priorities

·       updated Will reflecting your life now

·       trusteeship planning (so the right people manage money for children)

·       LPAs that ensure decision-making sits with the right person

·       replacement attorneys and executors

Common mistake

·       leaving an old Will in place and hoping “the system will know what I meant”.

Blended family or second marriage

Your priorities

·       a Will that balances spouse security with children’s protection

·       LPAs set up to reduce conflict under pressure

·       clear wording and practical instructions

·       a plan for “what if” scenarios (future grandchildren, changing relationships)

Common mistake

·       trying to keep things “simple” in a way that actually creates ambiguity.

Single person (no children)

Your priorities

·       Will naming beneficiaries and substitutes

·       executors who are capable and willing

·       both LPAs (because “next of kin” isn’t the same as legal authority)

·       asset list + document storage plan

Common mistake

·       putting it off because “it’ll just go to family anyway.”

Adult children caring for an ageing parent

Your priorities

·       LPAs done early (before capacity becomes uncertain)

·       a clear pack: where documents are, who the attorneys are, what the parent wants

·       a Will review if it’s outdated or unclear

·       a practical plan for care costs and decisions

Common mistake

·       waiting until after a hospital event when time, stress and paperwork collide.

Common mistakes this checklist prevents

If you only take one thing from this blog, take this: estate planning problems usually come from gaps.

This checklist helps prevent:

·       having a Will but no LPAs (so nobody can act while you are alive)

·       outdated beneficiary nominations on pensions/insurance

·       missing guardianship and trustee planning for children

·       property ownership not matching your intentions

·       family uncertainty because nobody knows where the documents are

·       avoidable conflict in divorced or blended families

FAQs

What documents do I need for estate planning in the UK?

Most people need: a valid Will, Property & Financial LPA, Health & Welfare LPA, plus up-to-date pension and insurance nominations and a clear record of where documents are stored.

Do I need an LPA if I already have a Will?

Yes, often. A Will only applies after death. LPAs protect you while you’re alive if you can’t make decisions.

How often should I review my estate plan?

Review after major life events (marriage, divorce, new children, new property), and otherwise every few years to ensure it still reflects your wishes.

Is estate planning only for wealthy people?

No. Estate planning is most valuable when it protects children, partners, and decision-making not just wealth.
