Dying without a will hands the decision to a formula

The points below about dying without a will are ordered by how much difference they make, not by how often they get repeated.

What intestacy means

Dying without a valid will means the estate is distributed according to a statutory order set out in law. That order is based on categories of relative rather than on relationships, needs or anything the deceased may have said. It also determines who has authority to deal with the estate, which is often a separate question from who inherits.

The rules are mechanical, which makes them predictable and entirely indifferent to individual circumstances. They exist to provide an answer rather than the right answer, and they are a default rather than a recommendation.

The gaps that surprise people

In many jurisdictions an unmarried partner has no automatic entitlement whatsoever, regardless of how long the relationship lasted. Stepchildren who were never legally adopted are frequently excluded, even where they were raised in the household. A surviving spouse may receive only a portion, with the remainder passing to children, including those from earlier relationships.

Where children are minors, arrangements for holding their share are imposed by law rather than chosen. Each of these outcomes occurs regularly and is entirely lawful, which is what makes the absence of a will consequential.

The practical burden

Someone must apply for authority to administer an estate, and without a will the process is often slower and more evidenced. Assets can be frozen during that period, which can leave a surviving household short of accessible money. Disputes are more likely where the statutory outcome differs from what family members believed was intended.

That combination of delay, cost and conflict falls on people who are also grieving. A will does not remove the administration but it removes most of the ambiguity around it.

What a will actually decides

A will names who inherits, who administers the estate, and often who cares for any minor children. It can also make specific gifts, establish trusts, and set out wishes that would otherwise be unknown. It does not override every rule: many jurisdictions reserve a share for certain relatives regardless of what a will says.

Some assets pass outside a will entirely, including jointly owned property and arrangements with nominated beneficiaries. That last point catches people out, because the will they wrote may govern less of the estate than they assume.

Keeping it valid

Formal requirements for a valid will differ by jurisdiction and typically involve signature and independent witnesses. Errors in execution are among the most common reasons a will fails, and they are entirely avoidable. In some jurisdictions marriage revokes an existing will automatically, and divorce alters its effect.

For most households, a will made in one country may or may not be effective over assets in another, which is a genuine complication for many households. These are precisely the areas where doing it properly with a qualified professional locally is worth the cost.

The right answer depends on your tax situation, which this cannot see.

Reviewing rather than writing once

A will reflects circumstances at the time it was made, and circumstances change more than people expect. Births, deaths, relationships ending, property purchases and moves between countries all warrant a review. Storing it somewhere findable, and telling someone where, is as important as writing it in the first place.

A will nobody can locate produces the same outcome as no will at all. This is general information about how intestacy works and is not legal advice; rules differ entirely by jurisdiction.

Everything above, in order of what to do first

1. What intestacy means. Dying without a valid will means the estate is distributed according to a statutory order set out in law.
2. The gaps that surprise people. In many jurisdictions an unmarried partner has no automatic entitlement whatsoever, regardless of how long the relationship lasted.
3. The practical burden. Someone must apply for authority to administer an estate, and without a will the process is often slower and more evidenced.
4. What a will actually decides. A will names who inherits, who administers the estate, and often who cares for any minor children.
5. Keeping it valid. Formal requirements for a valid will differ by jurisdiction and typically involve signature and independent witnesses.
6. Reviewing rather than writing once. A will reflects circumstances at the time it was made, and circumstances change more than people expect.

The takeaway

Without a will, a statute decides. It is a formula built for the average case, and almost nobody is the average case.

Costs compound as reliably as returns do, and in the same direction.
