Estate planning is the process of deciding who receives your assets, who can act for you if you lose capacity, and how taxes and legal delays will be handled after death. The biggest risks are simple: no valid will, no powers of attorney, outdated beneficiary forms, and no cash to cover taxes or probate delays.
- Most estate problems come from missing documents, not complicated strategies. Fix the basics first.
- Expats face extra traps: multiple legal systems, frozen bank accounts, and mismatched beneficiary forms.
- Build a simple “estate file”, create liquidity for taxes and delays, and review after every major life change.
Why estate planning fails in the real world
Most people assume estate planning is for the ultra-wealthy. In practice, it is a control problem, not a wealth problem.
When someone dies or loses mental capacity, three things happen quickly:
- Institutions freeze first and ask questions later. Banks, platforms and providers will usually restrict access until they see the right legal authority.
- The law fills any gaps. If you have not made valid choices, the default rules decide who inherits and who administers your estate.
- Time becomes expensive. Delays create costs, tax inefficiency, forced sales, and family stress.
For UK expats and globally mobile families, the complexity increases because you are often dealing with:
- assets in multiple jurisdictions
- different succession laws (including forced heirship concepts in some countries)
- different tax systems and definitions (residence, domicile, long-term residence)
- practical problems like frozen bank accounts and cross-border probate
This article focuses on five avoidable mistakes that repeatedly derail otherwise sensible plans, and how to fix them in a way that is practical, proportionate, and reviewable.
Mistake 1: Not having a valid will (or having the wrong will for your life)
Why it derails legacies
Without a valid will, you die intestate. That means the law decides:
- who inherits
- in what shares
- who administers the estate
- what happens for minor children (through a court-led process if needed)
This is where modern families get hit hardest:
- unmarried partners
- blended families
- second marriages
- children from prior relationships
- assets in more than one country
A will is not just about who gets what. It is also about execution: appointing the right people, giving them the right authority, and reducing friction for your family.
The UK intestacy reality (especially for England and Wales)
Many couples assume “everything goes to my spouse”. That is not automatically true under intestacy rules, and it is never true for cohabiting partners in England and Wales.
Even where a spouse inherits a large share, the structure may still:
- force earlier distributions than you would choose
- create administrative complexity
- trigger IHT inefficiency (depending on your broader situation)
- increase the chance of disputes
Scotland and Northern Ireland have different regimes. If you have UK ties across borders, treat “UK intestacy” as three separate systems, not one.
Expat complication: one will rarely covers everything cleanly
If you have assets in the UAE or elsewhere in the Middle East, you also need to think about:
- whether a UK will is recognised in practice
- whether a local registry exists (for example, DIFC or ADJD for non-Muslims in the UAE)
- how local courts treat joint accounts, property ownership, business interests, and guardianship
- what happens operationally in the days after a death (including account freezes)
Key point: Many expats need co-ordinated wills, not “one will to rule them all”.
Common will mistakes to avoid
- A will that is not validly executed (witnessing errors are more common than people realise).
- A will that unintentionally revokes another will in a different country.
- Using the wrong executors (too old, overseas, unwilling, or likely to be in conflict).
- No guardians named for minor children (or no backups).
- Not aligning pension and insurance nominations with the will (these usually sit outside the will).
- No plan for digital access (phones, email, two-factor authentication, cloud storage).
The fix: your “minimum viable will” checklist
A strong will does not have to be complex, but it must be correct. At minimum:
- appoint executors (plus backups)
- name beneficiaries clearly
- name guardians (plus backups) for minor children
- include powers for executors to deal with digital assets and practical administration
- include appropriate trust provisions where needed (especially for minors or blended families)
- store it securely and tell executors where it is
If you are internationally mobile, add:
- a clear plan for which will governs which assets
- confirmation that your wills do not conflict
- local legal advice where you hold significant assets outside the UK
Mistake 2: Kicking the can down the road (waiting for “perfect”)
Why delay is the silent killer
Estate planning is rarely urgent until it is too late. The highest-risk period is often the busiest: young children, peak career, mortgages, cross-border moves, growing assets.
Delaying creates two compounding risks:
- Document risk: nothing is signed when something happens.
- Complexity risk: the longer you wait, the more complicated your estate becomes.
The practical fix: do it in two phases
Phase 1 (this month): Minimum viable estate plan
- Will (or co-ordinated wills where needed)
- Executors and guardians
- Beneficiary nominations reviewed for pensions and life cover
- A simple estate inventory (one page is fine)
- A folder that your spouse or trusted person can access
Phase 2 (over the next 90 days): Upgrade for resilience
- LPAs (see next section)
- Trust planning where appropriate
- Liquidity plan for tax and delays
- Cross-border review (local wills, forced heirship risk, probate route)
- “What if” stress test (death abroad, incapacity abroad, dependants, business continuity)
A simple rule for expats
If you have assets in more than one country, treat estate planning as an annual review item, not a one-off project.
Triggers that should force a review within 30 days:
- marriage or divorce
- birth of a child
- buying property in a new country
- a major job change or business sale
- moving country (or planning to move)
- large change in net worth
- death in the family (because it exposes practical issues fast)
Mistake 3: Not putting Lasting Powers of Attorney (LPAs) in place
Why LPAs matter more than most people think
A will only helps after death. LPAs protect you while you are alive.
If you lose mental capacity temporarily or permanently, no one automatically has the legal right to:
- deal with your sole bank and investment accounts
- manage property transactions
- handle pensions and certain provider interactions
- make health and welfare decisions in the way you would choose
Even spouses can be blocked without the right legal authority.
What LPAs are (plain English)
In England and Wales there are two main LPAs:
- Property and Financial Affairs LPA: money, bank accounts, investments, property, bills.
- Health and Welfare LPA: medical decisions, care, life-sustaining treatment preferences.
You appoint attorneys you trust, set instructions and preferences, and register the documents.
Scotland and Northern Ireland have different frameworks. If you have cross-border UK ties, you need jurisdiction-specific legal advice.
Common mistakes with LPAs
- Only doing the financial LPA and ignoring health and welfare.
- Choosing the wrong attorneys (conflicts, capability, geography, reliability).
- Not registering LPAs (unregistered LPAs are not usable).
- Not telling anyone where the originals are stored.
- No guidance on how you want decisions made (especially for complex families).
Expat complication: capacity events are more likely abroad than people expect
If you live abroad, the operational risk rises:
- time zones
- local hospital systems
- document recognition
- family travelling for emergency support
- assets in multiple countries needing management simultaneously
You want your plan to work when life is messy, not when life is tidy.
The fix: your LPA action list
- Decide who you would trust to act for you, and who should not act.
- Put both LPAs in place (financial plus health and welfare).
- Register them properly and keep copies accessible.
- Write a short guidance note for your attorneys: where key documents are, which professionals to contact, and your core preferences.
- For expats: discuss local equivalents and recognition with a solicitor who understands your jurisdictions.
Mistake 4: Failing to protect children’s inheritances (divorce, remarriage, and “bloodline leakage”)
Why this catches high earners and expats
Families are more complex than intestacy rules assume. Second marriages, step-children, children from prior relationships, and international moves increase the risk that your wealth ends up:
- with the “wrong” branch of the family
- exposed in a divorce settlement
- distributed earlier than you intended
- mismanaged at the wrong age
This is not about controlling people from the grave. It is about recognising predictable legal and human realities.
The two classic scenarios
Scenario A: You leave everything outright to your spouse
Your spouse can choose to do the right thing, but legally they can also:
- remarry
- change their will
- spend down assets
- be influenced by others
- have assets pulled into a care or legal dispute
Scenario B: You leave assets outright to adult children
That can expose wealth to:
- divorce proceedings
- bankruptcy
- poor decision-making in their 20s and 30s
- family pressure and conflict
Practical tools that can help (without over-engineering)
- Trusts within the will for minors or vulnerable beneficiaries.
- Discretionary trust structures to keep flexibility and protect against divorce and creditor risk.
- Life interest trusts (in the right situations) to balance a spouse’s security with protecting capital for children.
- Letters of wishes to guide trustees without locking in rigid rules.
- Alignment with beneficiary nominations for pensions and life cover.
Trusts are powerful but regulated and legally technical. The goal is suitability, not complexity.
Expat angle: forced heirship and local succession concepts
Some countries restrict freedom to distribute assets as you choose. Even where the law has evolved, practice and documentation still matter.
If you have assets in the Middle East, you should not rely on assumptions like:
- “joint ownership solves it”
- “my UK will covers it”
- “my spouse can just deal with it”
You need a clear legal pathway for your family.
The fix: “divorce-proofing” checklist
- Identify who you must protect (spouse, children, dependants, parents).
- Decide what outcomes you want if your spouse remarries.
- Decide what age and structure is sensible for children receiving capital.
- Consider trusts where appropriate, especially for blended families or significant wealth.
- Keep beneficiary nominations and life policies aligned with the intent of the will.
- Review after every major life change, especially marriage, divorce, and births.
Mistake 5: Not making provision for the IHT bill (and probate delays)
Why liquidity matters more than most people expect
Inheritance Tax (IHT) is often described as a “tax on the dead”. In practice it is also a liquidity problem for the living.
Even when the estate is valuable, families can face a cash crisis because:
- tax can be due before assets are easily sold
- probate delays restrict access to accounts
- cross-border probate extends timelines
- property and business interests are not instantly liquid
- markets can be down at the wrong time
Typical “asset rich, cash poor” estate examples
- UK property plus pensions, but little cash
- rental properties where rent stops or gets trapped during administration
- business ownership interests requiring valuation and legal steps
- portfolio assets held across platforms and jurisdictions
- expat families relying on one main bank account for day-to-day life
What “IHT planning” actually looks like in practice
At a practical level, your family needs:
- a rough estimate of potential tax exposure
- a plan for where cash will come from quickly
- a plan for who will do what in the first 30 days after a death
- documentation that reduces delay
Options to create liquidity
- Maintain a cash reserve outside the most administratively complex jurisdiction.
- Hold appropriate low-volatility assets that can be sold quickly.
- Use life insurance where suitable to provide quick liquidity.
- Consider writing life cover in trust where appropriate so proceeds can be outside the estate and paid quickly to trustees.
- Plan gifts carefully (this is highly fact-specific and depends on UK rules, residency, and other taxes).
- Review ownership structures for property and business assets.
The right solution depends on family structure, domicile or residence status, asset mix, and jurisdiction.
Expat-specific liquidity risk
In many countries, the operational reality is harsh: accounts can be frozen pending court orders, and timelines can be slow. Even when the ultimate legal outcome is fine, your family may struggle in the meantime.
That is why you should plan for continuity of cash flow for dependants, not just long-term wealth transfer.
The fix: “liquidity first” planning steps
- Estimate potential IHT exposure at a high level (do not aim for perfection, aim for direction).
- Identify which assets could be sold quickly and which cannot.
- Decide where the “first 6 months of living costs” would come from for your family.
- Review whether life cover is needed as liquidity, not as an investment.
- If using life cover, consider whether trust ownership is appropriate.
- Write down the plan in plain English so your executors can execute it.
Putting it into practice: the 10-step estate planning reset
If you do nothing else, do this:
- Write a one-page estate inventory: assets, liabilities, jurisdictions, key account numbers, key contacts.
- Create or update your will: executors, guardians, beneficiaries, and trust provisions where needed.
- If you have assets abroad, co-ordinate wills: avoid conflict and accidental revocation.
- Review beneficiary nominations: pensions, life cover, and any account with nominations.
- Put LPAs in place: Property and Financial Affairs plus Health and Welfare (England and Wales).
- Create an “estate file”: will, LPAs, passport copies, marriage certificate, children’s documents, key policies.
- Plan for liquidity: at least 6 to 12 months of family cash flow and any likely tax needs.
- Stress test your plan: death abroad, incapacity abroad, remarriage, minor children, market crash.
- Align tax planning: make sure your will strategy matches your residence and long-term plans.
- Set review dates: annually, and after every major life event.
Common mistakes expats should watch for (quick list)
- Assuming a UK will automatically works in the UAE or across the Gulf
- Assuming joint accounts avoid freezes or probate
- Not naming guardians or not naming backups
- Outdated beneficiary nominations after marriage, divorce, or births
- Planning only for death, not incapacity
- No cash plan for the first months after death
- Overcomplicating structures without understanding governance, costs, and reporting
- Relying on verbal promises rather than enforceable documents
When to get advice (complexity flags)
You should treat this as a signal to get qualified legal and tax advice if any of the following apply:
- assets in more than one country
- children from a prior relationship or a blended family
- significant business ownership or partnership interests
- property in multiple jurisdictions
- dependants with additional needs
- substantial pension wealth and multiple nomination forms
- expected IHT exposure or unclear long-term residence position
- US connections (US estate tax exposure can be a separate issue, even for non-US persons holding US assets)
- you live in the Middle East and want your plan to work under local rules and practice
A final perspective: control beats perfection
A good estate plan is rarely the most complex plan. It is the plan that:
- works operationally
- is legally valid
- is understood by the people who must execute it
- is reviewed as life changes
If your family cannot find the documents, cannot access cash, and cannot get the right legal authority quickly, even a “clever” plan can fail.
Start simple. Make it executable. Then refine.
FAQs
1) What happens if I die without a will in the UK?
If you die without a valid will, you die intestate and the law decides who inherits and who administers your estate. The rules differ across England and Wales, Scotland, and Northern Ireland, so “UK intestacy” is not one system. In England and Wales, unmarried partners do not inherit automatically under intestacy rules, which catches many modern families. Intestacy can also increase delays because administrators must be appointed under statutory rules and institutions often require extra evidence before releasing assets. A will gives control, reduces uncertainty, and lets you appoint executors and guardians.
2) Do I need a separate will if I live in the UAE or own assets there?
Often, yes. Many expats benefit from having a UK will for UK assets and a locally recognised will for UAE assets, co-ordinated so they do not conflict or revoke each other. The goal is to ensure your plan is enforceable in practice where the assets sit. Local processes can involve court orders and practical delays, including bank account restrictions after death. The right approach depends on where you live, where the assets are held, and the structure of ownership. Take local legal advice and make sure your wills are designed to work together.
3) What is a Lasting Power of Attorney and why do I need one?
A Lasting Power of Attorney (LPA) lets you appoint trusted people to make decisions for you if you lose mental capacity. In England and Wales, there are two main LPAs: Property and Financial Affairs, and Health and Welfare. Without LPAs, your family may be unable to access or manage sole accounts, investments, or property, and may need court involvement, which is slow and stressful. LPAs are not only for older people. Accidents and illness can happen at any age, and expats face extra friction because decisions may need to be made across time zones and jurisdictions.
4) How can I protect my children’s inheritance from divorce or remarriage risk?
Outright gifts to a spouse or adult children can be exposed to future remarriage, divorce, bankruptcy, or poor decisions. The practical solution is often a will structure that balances support with protection, such as discretionary trusts or life interest trusts, supported by a letter of wishes. This allows trustees to control timing and purpose, rather than handing over capital with no guardrails. The right structure depends on your family situation, asset levels, and jurisdictions. The key is to plan for predictable life events, not ideal scenarios.
5) How do families pay inheritance tax if the estate is mostly property or investments?
This is a common problem. Even when an estate is valuable, it may not have accessible cash at the time tax is due, especially if probate delays restrict access to accounts. Families may be forced to sell assets at a poor time or borrow short-term. A liquidity plan can include cash reserves, a sell-down strategy for investments, and in some cases life cover designed to provide quick liquidity. Writing life cover in trust can be appropriate in some situations because it can keep proceeds outside the estate and speed up access for beneficiaries. This is fact-specific and needs advice.
6) How often should I review my will and estate plan?
Review at least annually and after any major life event: marriage, divorce, children, property purchases, relocation, major changes in net worth, or business changes. For expats, add a review after any change of country because legal recognition and tax exposure can shift. Also review beneficiary nominations regularly because pensions and insurance nominations often sit outside the will and can override your intended outcome. A short annual review is usually enough to keep the plan aligned, but a full rewrite may be needed after major changes.
