The inheritance you should not build a plan around

Treat the sections below as a sequence. With expected inheritances, getting the early decisions right makes the later ones much easier.

Four things that reduce it

Care costs, longer lifespans, remarriage and simply spending it are the usual reasons an expected inheritance is smaller or absent. In systems where long-term care is privately funded, it is entirely possible for an estate to be consumed by a few years of residential care. That is the intended operation of those systems rather than a failure, and it surprises families repeatedly.

None of this is a reason for resentment; it is a reason not to plan around the money.

It arrives later than it used to

As lifespans lengthen, inheritances increasingly pass to people in their fifties and sixties rather than their thirties and forties. That is after the years when a deposit, childcare or a career change would have been transformative. A plan that depends on money arriving at an unknown date, decades away, is not a plan in any useful sense.

On an ordinary week, treating it as a possible improvement to a retirement position, rather than as a solution to a current problem, is the realistic framing.

Nothing is promised

A will can be rewritten at any point while the person has capacity, and intentions expressed verbally have no legal force. Remarriage revokes a will automatically in several jurisdictions, which can redirect an estate entirely without anyone intending it. Estates are also reduced by debts, taxes and administration costs before anything is distributed.

Where an estate is disputed, distribution can be delayed for a long time and reduced by legal costs.

Property is not cash

Much inherited wealth is held in property, which must be sold, maintained and taxed before it becomes usable money. Where several siblings inherit a property jointly and disagree about selling, the situation can persist for years. Costs of maintaining, insuring and securing an empty property fall on the estate or the beneficiaries in the meantime.

This is one of the most common practical difficulties and is largely preventable by a clearly drafted will.

Tax treatment varies enormously

Some countries tax the estate, some tax the recipient, some have thresholds and exemptions, and some tax neither. Rules on gifts made before death, on property and on transfers between spouses differ substantially and change with governments. Anyone with a cross-border element — assets or people in more than one country — is in genuinely complicated territory.

This is professional advice territory in every jurisdiction involved rather than something to research generally.

None of this is a substitute for talking to a clinician if something feels wrong.

Plan without it, and adjust if it arrives

A household plan that stands on its own income and provision is robust regardless of what happens to any estate. If an inheritance arrives, it improves a position that was already viable, which is the only comfortable way to receive one.

For most people, it also removes an unhealthy dynamic in which financial plans are silently attached to a relative's death. Where the sums are large, the sensible response on receipt is to park it and take advice before deciding anything.

The takeaway

Build a plan that works without it. Anything that arrives is then an improvement rather than a rescue.

Small and repeatable beats ambitious and abandoned, almost every time.
