Will

A will is a legal document setting out what should happen to a person's property, money and possessions after they die, and who should carry out those instructions. It also lets parents name guardians for children under 18.

Without a valid will, the law decides who inherits under fixed intestacy rules that may bear no relation to what the person actually wanted.

What it means

A will names an executor, the person responsible for gathering the assets, paying debts and taxes, and distributing what remains to the named beneficiaries. Formal requirements vary by jurisdiction, but almost all require the document to be in writing, signed by the person making it, and witnessed by people who do not benefit from it.

The estate is settled in a strict order, and beneficiaries come last. Funeral expenses, debts, administration costs and any tax due are all paid first, and only the residue, the amount left over, is available to distribute under the will's instructions.

Several important assets often sit entirely outside a will, which surprises many families. Pension pots, life insurance policies and jointly owned property usually pass by beneficiary nomination or survivorship, so an outdated nomination form can override a carefully drafted will.

For business owners the stakes are higher than for most households. A will should sit alongside a shareholders' agreement or partnership agreement so that shares pass in a way the surviving owners can live with, rather than leaving a spouse and the remaining partners in an unplanned arrangement.

Wills should be reviewed after any major life event: marriage, divorce, a birth, a death, a business sale or a move to another country. In many jurisdictions marriage automatically revokes an existing will, which means a couple can be intestate without realising anything has changed.

In practice

Real-world examples.

1

Example

A restaurant owner dies without a will, leaving a partner of 14 years they never married. Under the intestacy rules the estate passes to his adult children and his parents, and the surviving partner has no automatic entitlement at all.

2

Example

A couple with two children under ten write mirror wills naming a guardian and setting up a trust so the children receive their inheritance at 25 rather than 18. The trust also names two trustees who will manage the money in the meantime.

3

Example

A woman leaves her entire estate to her two daughters in a will written in 2009, but her workplace pension nomination form still names her first husband. The pension trustees pay him, because the nomination sits outside the will entirely.

Think of it

Will is your instructions for after death-who gets what and who's in charge.

Formula

Calculation

Residuary estate = gross estate - debts and funeral costs - taxes - specific gifts Take an estate with a gross value of $1,200,000, made up of a house, savings and personal possessions. Debts and funeral costs come to $85,000, and the will leaves specific gifts of $150,000: $100,000 to a niece and $50,000 to a charity. On these figures no estate tax is due, because the estate falls below the applicable threshold. Residuary estate = $1,200,000 - $85,000 - $150,000 = $965,000. The will leaves the residue 50% to the surviving spouse and 25% to each of two children. The spouse receives $965,000 x 50% = $482,500, and each child receives $965,000 x 25% = $241,250. The three shares add back to $482,500 + $241,250 + $241,250 = $965,000, confirming the residue is fully allocated.

Case study

Seen in the real world.

The following is an illustrative and entirely fictional example. Tobias Reed, an invented owner of a 30-person printing business, held 70% of the shares, with his long-standing operations director holding the other 30%. His will, drafted a decade earlier, left everything to his wife, and the company had a shareholders' agreement with no cross-option or buyout provision.

When Tobias died unexpectedly, his wife inherited a 70% stake in a business she had never worked in and could not sell, while the operations director suddenly reported to a majority shareholder with no industry experience. The estate also faced a tax bill it could not fund without selling shares that nobody wanted to buy.

In this fictional account, the parties eventually agreed a phased buyout over five years at a discounted valuation, and the business lost two major clients during the uncertainty. A cross-option agreement backed by life insurance, costing a few thousand dollars a year, would have funded a clean purchase at a fair price within weeks.

Watch out

Common mistakes.

  • Assuming a will covers every asset, when pensions, life policies and jointly owned property usually pass outside it by nomination or survivorship.
  • Writing a will and never revisiting it, so that it names a deceased executor, an ex-spouse or children who have since been born.
  • Using a beneficiary or a beneficiary's spouse as a witness, which in many jurisdictions invalidates that person's gift even though the will itself stands.

Questions

People also ask.

What happens if someone dies without a will?

The intestacy rules of the relevant jurisdiction decide who inherits, following a fixed order of relatives that often excludes unmarried partners and stepchildren entirely.

Can a will be challenged?

Yes, on grounds such as lack of mental capacity, undue influence, improper execution or failure to provide for a dependant, which is why clear drafting and good records matter.

Does a business owner need anything beyond a will?

Usually yes, because a shareholders' or partnership agreement determines what actually happens to the shares, and the two documents need to say the same thing.
