The Unread Clause: Aligning Beneficiary Nominations With Your Wider Estate Plan

A portfolio can be assembled with real care — costs negotiated, overlap examined, rebalancing bands respected — and still come apart at the last hurdle because a form signed a decade ago names someone who no longer belongs in the plan. Beneficiary nominations sit at the seam between investment administration and estate planning. They are also among the most frequently overlooked documents in UK household finance, largely because no one sends a reminder when circumstances change.

Two wrappers, two very different mechanisms

The first point to establish is that pensions and ISAs do not work alike, and treating them as though they do is the source of most confusion.

A defined contribution pension — whether a workplace scheme, a SIPP or a personal pension — sits outside your estate for inheritance tax purposes at present, and death benefits are paid at the discretion of the scheme administrator or trustees. Because that discretion exists, the administrator asks for guidance: an expression of wish, sometimes called a nomination. It is not legally binding. In practice it is followed in the overwhelming majority of cases, precisely because it is the evidence of what the member wanted. The form also influences the form of the benefit — a lump sum, a dependant's drawdown account, or an annuity — which can matter considerably to the recipient.

An ISA has no equivalent. There is no statutory nomination, no trustee discretion and no mechanism by which a platform instruction overrides your will. Adult ISA assets form part of your estate and pass under your will, or under the intestacy rules if there is none. What exists instead is the additional permitted subscription: a surviving spouse or civil partner can claim a one-off ISA allowance equal to the value of the deceased's ISAs, and the accounts retain their tax-advantaged status during administration. That is a valuable relief, but it is a relief for a spouse or civil partner — it does nothing for anyone else.

The practical difficulty is that many platforms display a 'beneficiary' or 'next of kin' field on an ISA. These are administrative records. They help a provider know whom to contact after a death. They do not direct the money. Investors who assume otherwise can end up with an estate that divides quite differently from what they intended.

Why a stale form carries real weight

An out-of-date nomination is not a technicality. It can produce three distinct problems at once.

First, it can defeat your intentions. A form naming a former partner, or splitting benefits between children in proportions chosen before a second marriage, will usually be honoured by trustees who have no reason to doubt it. A will drafted later cannot correct a pension nomination, because the pension is not an asset the will controls.

Second, it can create conflict. Where a will divides the estate one way and a pension nomination another, the people left behind are handed a puzzle at the worst possible moment. Disagreement between siblings, or between a spouse and children from an earlier relationship, is far more common than most families expect, and the costs — financial and personal — are rarely worth the five minutes it would have taken to update a form.

Third, the stakes are rising. Unused pension funds are due to be brought within the scope of inheritance tax from April 2027, which means the question of who receives them, and in what form, will carry tax consequences as well as personal ones. Nominations that were once a matter of courtesy are becoming a genuine planning document.

The moments that call for a fresh look

Nominations age badly because life moves faster than paperwork. The trigger points are fairly consistent.

• Marriage or civil partnership. In England and Wales, marrying revokes an existing will unless it was drafted in contemplation of that marriage — but it does not automatically rewrite a pension nomination.
• Divorce or separation. Some schemes void a nomination on divorce; many do not. A former spouse named on a form may still be the person the trustees pay.
• Bereavement. A nomination naming a partner who has since died may leave no effective instruction at all.
• A new child, grandchild or dependant. Particularly relevant where benefits are split by percentage rather than by name.
• A platform move or scheme merger. Transfers do not always carry nomination data across, and a newly opened SIPP may sit with a blank form for years.
• Reaching retirement or crystallising benefits. The point at which the scheme's death benefit options should be reviewed alongside the nomination.
• Cohabitation. Neither a pension nomination nor an intestacy gives an unmarried partner an automatic entitlement. A carefully worded nomination may be the only thing that provides for them.

A practical checklist

The aim is not to complete a single form, but to keep several documents consistent with one another.

1. Build a complete inventory. List every wrapper: current and legacy workplace pots, SIPPs, personal pensions, self-invested and stocks-and-shares ISAs, Lifetime ISAs, junior accounts and any investment bonds. Old workplace schemes are the usual gap.
2. Request the nomination currently on file. Not the copy in your drawer — the version the administrator holds. These differ more often than people expect.
3. Check the arithmetic. Percentages should total 100, names should be current, and any substitute or contingent beneficiary should still be appropriate.
4. Read the will alongside the forms. The two should describe the same outcome. Where a pension is meant to provide for one person and the residue for others, say so expressly.
5. Consider a letter of wishes. For larger or more complicated estates, a short explanatory note to trustees can prevent an otherwise defensible nomination from being misread.
6. Diarise a review. Every two to three years, and immediately after any event on the list above.
7. Tell someone where things are. An executor who does not know a SIPP exists cannot prompt the administrator, and unclaimed benefits are a recurring feature of estate administration.

Where nominations stop

It is worth being clear about the limits. An expression of wish does not bind trustees, who must still satisfy themselves that the payment is appropriate. An ISA field does not override a will. And no nomination can substitute for a valid, current will — particularly for cohabitants, for whom the intestacy rules offer very little.

Estate planning is often described as a set of documents. In practice it is a set of alignments. The nomination in the margin is a small piece of paper, but it is the piece that decides whether the plan you have written and the plan that takes effect are the same plan.
