Your company can still exist on Monday morning.

That doesn’t mean anyone can run it.

The bank account needs authorising. Payroll needs approving. Employees need decisions. Suppliers need paying. Clients expect calls to be returned.

If the person who normally makes those decisions died or became unable to work over the weekend, what would happen next?

For many SMEs, that person is the owner.

They may also be the managing director, largest shareholder, primary client relationship, bank signatory and the only person who understands some of the company’s most important systems.

It is an enormous concentration of responsibility in one individual.

Yet many successful business owners spend years planning how to grow their company without making equally detailed plans for what happens if they can no longer run it.

That is where business succession planning becomes important.

And succession planning isn’t only about retirement.

Death matters.

Incapacity matters too.

For an owner-managed SME, either could turn a successful business into an operational problem remarkably quickly.

The Business May Survive You. Can It Operate Without You?

A limited company has a legal identity separate from its owner.

The death of its founder does not automatically mean the company ceases to exist.

But legal existence and operational continuity are very different things.

Imagine a business employing 20 people.

Its founder owns all the shares and is its sole director.

They approve major payments.

They manage the relationship with the bank.

Several important clients deal directly with them.

Some systems use two-factor authentication through their phone.

They understand the company’s cash flow better than anybody else.

Then, unexpectedly, they die.

The company may still exist.

Its employees still have employment contracts.

Its customers still expect service.

Its suppliers still expect payment.

But suddenly the person sitting at the centre of almost every important decision is gone.

This is one reason SME business succession planning needs to consider much more than simply who inherits the shares.

Ownership, Control and Operation Are Different Things

For business owners, it is useful to separate three questions.

Who owns the business?

Who controls the business?

Who can actually run the business?

They are not necessarily the same person.

A spouse or children might ultimately inherit the deceased owner’s shares.

A surviving director may have responsibility for operating the company.

A senior employee may understand the business better than either of them.

Estate planning establishes what happens to someone’s assets.

Business succession planning needs to connect that outcome with the practical reality of keeping the company operating.

For an SME, getting one without the other can create significant problems.

What Happens to a Sole Trader?

The structure of the business matters enormously.

A sole trader and their business are not separate legal entities in the same way that an individual and a limited company are.

HMRC’s guidance states that a sole trader’s trade will normally cease on death unless the personal representatives continue trading.

That can create immediate practical questions.

Who deals with existing customers?

Who completes outstanding work?

Who collects money owed?

Who pays creditors?

What happens to employees?

Can the business itself be sold?

If a valuable trading operation depends almost entirely on one individual, succession planning needs to begin before those questions become urgent.

What Happens to a Partnership?

Partnerships introduce different issues.

The partnership agreement is particularly important.

Where appropriate provisions have not been made, the death of a partner can potentially result in the partnership being dissolved under the Partnership Act 1890.

A well-drafted partnership agreement can instead establish what should happen when one partner dies, how their interest is valued and whether the remaining partners have a mechanism to continue the business.

For a business with several owners, this leads to another important question:

Do the surviving owners want to run the company with the deceased owner’s beneficiaries?

The family may want the economic value of the deceased person’s share.

The remaining owners may want control of the business.

Those objectives can potentially be reconciled, but they require planning.

What Happens If a Company Director Dies?

A limited company can continue following the death of a director, but the company’s articles and ownership structure become important.

Where there are surviving directors, they can generally continue managing the company subject to its articles.

If a sole director dies but there are surviving shareholders, those shareholders may be able to appoint a replacement director.

The more difficult scenario is where the deceased was both the sole shareholder and sole director.

The model articles for private companies contain provisions allowing the personal representatives of the last shareholder to appoint a director in certain circumstances.

But relying on the family to discover the correct corporate procedure after an unexpected death is not much of a succession plan.

The better question is:

Have you already established how control of the company would continue?

What If You Don’t Die, But Can’t Make Decisions?

Death receives most of the attention in estate planning.

For SME owners, incapacity can be equally disruptive.

A serious accident, stroke, neurological illness or other event could leave someone alive but temporarily or permanently unable to make decisions.

Their will does not take effect because they have not died.

Their shares still belong to them.

But who can deal with their financial affairs?

A Property and Financial Affairs Lasting Power of Attorney can allow appointed attorneys to make certain financial decisions on someone’s behalf.

Business owners, however, need to be particularly careful.

A director’s appointment is personal.

Simply being someone’s attorney does not ordinarily mean you can automatically assume their position as a company director.

This creates an important distinction.

An LPA may help someone deal with the owner’s financial interests. It does not automatically replace the director responsible for running the company.

For some SME owners, separate arrangements for personal and business affairs may be appropriate.

The company’s articles, shareholder arrangements, board structure and LPAs need to work together rather than being considered independently.

Who Can Access the Bank on Monday Morning?

Succession planning can become overly focused on legal documents.

SMEs also need operational succession.

Consider everything that might depend on the owner:

business banking;

payroll approval;

accounting systems;

supplier relationships;

key customer relationships;

domain names;

website hosting;

cloud systems;

insurance;

contracts;

password managers;

payment processors;

two-factor authentication;

regulatory accounts;

and access to critical company records.

A company can have perfectly drafted shareholder arrangements and still grind to a halt because nobody can access something essential.

This is particularly common in founder-led businesses where systems have evolved gradually over many years.

The owner knows how everything works because they built it.

The problem is that nobody else necessarily does.

What Happens to the Shares?

Shares owned by an individual normally form part of their estate on death.

Who ultimately receives them will depend upon the deceased’s will or, where there is no valid will, the applicable intestacy rules, together with the company’s governing documents and any relevant shareholder arrangements.

But inheriting shares and taking immediate control of the company are not necessarily the same thing.

There can be a period during which personal representatives need to deal with the estate and the transmission of shares.

For an SME where one shareholder controls most or all of the voting power, that period can matter.

Again, this demonstrates why the will cannot be viewed separately from the company’s succession arrangements.

Would Your Business Partners Want Your Family as Their New Partner?

Suppose three founders each own one third of a company.

One dies.

Their shares ultimately pass to their spouse.

The spouse may have little interest in the business.

The two surviving founders may want to continue operating it.

The obvious solution might appear to be for the surviving owners to buy the shares from the deceased owner’s estate.

But that creates another question:

Where does the money come from?

If the deceased’s share is worth £750,000, the remaining shareholders may not have £750,000 sitting in cash.

The company itself may not have sufficient available resources either.

This is where shareholder protection, appropriate insurance and carefully structured buyout arrangements can become part of succession planning.

The objective can be mutually beneficial.

The family receives value for the deceased owner’s interest.

The surviving shareholders retain control of the business.

The company continues operating.

But these arrangements need to be structured carefully.

HMRC distinguishes between different types of sale and purchase arrangements when considering eligibility for Business Relief. A binding agreement requiring shares to be sold can have different tax consequences from appropriately structured option arrangements.

The legal, insurance and tax elements therefore need to be considered together.

The Inheritance Tax Position Changed in April 2026

Business owners should also review assumptions they may have held for many years about Inheritance Tax.

Historically, qualifying business interests could potentially receive 100% Business Relief, leading some owners to assume that their company would simply fall outside the effective IHT calculation.

From 6 April 2026, the rules changed.

A £2.5 million individual allowance now applies to property qualifying for 100% Agricultural Property Relief and Business Relief.

Qualifying value above the available allowance generally receives relief at 50%, rather than 100%.

Unused allowance may potentially be transferable between spouses and civil partners, subject to the relevant conditions.

For owners of successful SMEs, this matters.

A company that began with almost no value may now be worth £3 million, £5 million or £10 million.

The founder may still be operating on an estate plan written when the company was worth a fraction of that.

The question is no longer simply:

Does my business qualify for Business Relief?

It may also be:

How much is the business worth, how much relief is available and where would any resulting tax liability be funded from?

What Is Your Business Actually Worth?

SME owners frequently underestimate this question.

A company does not need to be publicly listed to have substantial value.

Value might come from:

recurring revenue;

contracts;

intellectual property;

property;

cash reserves;

customer relationships;

brand value;

technology;

distribution agreements;

or simply consistent profitability.

A business producing £500,000 of annual profit could represent one of the largest assets in its owner’s estate.

Yet unlike a bank account, its value is not printed on a statement every month.

Business succession planning therefore needs to consider valuation as well as ownership.

If your company has grown considerably since your estate planning was last reviewed, the assumptions underlying that plan may no longer be appropriate.

What About SME Owners Living Overseas?

For internationally mobile entrepreneurs, another layer is added.

You might own shares in a UK company while living in Dubai.

You might own businesses in several jurisdictions.

Your spouse may live with you overseas while adult children live elsewhere.

Your will may have been written in Britain years before you moved.

Since April 2025, UK Inheritance Tax treatment of foreign assets has moved towards a residence-based framework, making an individual’s UK residence history increasingly important.

Moving overseas therefore does not automatically resolve the UK estate-planning position.

Business interests can also involve different corporate laws, tax systems and succession rules.

For internationally mobile SME owners, personal estate planning and corporate succession planning should therefore be considered together.

Six Questions Every SME Owner Should Be Able to Answer

A useful starting point is surprisingly simple.

1. Who owns the business if I die?

Does your will reflect your current intentions and current company value?

2. Who controls it?

Can another director or appropriate person make the decisions required to keep the company functioning?

3. What happens if I’m alive but incapacitated?

Have LPAs and the company’s governance arrangements been considered together?

4. Can somebody actually operate the business?

Could they access banking, payroll, critical systems, contracts and operational information?

5. If another shareholder needs to buy my shares, where does the money come from?

Have shareholder protection, insurance and purchase arrangements been considered?

6. What would the tax position be?

Does the business qualify for Business Relief, how much relief may be available under the post-April 2026 rules, and could the estate fund any liability without damaging the company?

If any of those questions produces the answer “I’m not sure”, there is something worth reviewing.

A Succession Plan Is Not a Plan to Leave

Some founders avoid succession planning because it feels like planning their retirement.

It isn’t.

A good succession plan can allow an owner to continue running the business for another 20 years.

It simply removes the assumption that the company can only function while one particular person is available.

That can make the business stronger today.

Clear authority.

Better systems.

Documented processes.

Reduced key-person dependency.

Appropriate insurance.

Updated wills.

Appropriate LPAs.

Shareholder arrangements that reflect what the owners actually want.

These are not simply preparations for death.

They are part of building a more resilient SME.

What Happens to Your Business If Something Happens to You?

For many SME owners, the business represents years or decades of work.

It may provide the family’s income.

It may employ dozens of people.

And it may ultimately be one of the largest assets the owner passes to the next generation.

Yet its value can depend heavily upon one person being there tomorrow morning.

Business succession planning asks what happens when they aren’t.

Who owns it?

Who controls it?

Who can run it?

And what does the family ultimately receive?

Those questions are easier and considerably less expensive to answer while the owner is still sitting at the table.

Review Your Business Succession Plan

Carey Suen works with SME owners, entrepreneurs and internationally mobile families to consider how business interests fit within their wider estate and wealth planning.

If your company has grown, your family circumstances have changed, you’ve moved overseas or your succession arrangements haven’t been reviewed recently, it may be worth establishing whether the plan you have still reflects the business you own today.
