Beyond the Bloodline: Shaping an Estate Around Chosen Relationships in 2026

For a married couple without children, the intestacy rules do not simply hand everything to the surviving spouse. In England and Wales, the surviving spouse or civil partner receives personal chattels and a fixed statutory legacy, with the remainder divided between the spouse and the deceased’s parents or siblings. For unmarried partners, there is no automatic entitlement at all. This is the quiet trap: a childless estate can be distributed to people the deceased barely knew, or to relatives who never formed part of the couple’s life.

The point is not that the law is unreasonable. It is that the law cannot know which relationships mattered. A will, by contrast, can say so expressly. For couples and individuals without children, estate planning is less about following a family tree and more about identifying a chosen circle and giving it legal shape.

Begin with the default, then depart from it

A will remains the primary instrument for displacing intestacy. The drafting should name people, not categories. A gift to ‘my family’ or ‘my relatives’ may create uncertainty and invite dispute. Specific gifts of personal possessions, followed by a clear residuary clause, are usually more effective. The residue is the part of the estate left after debts, taxes and specific gifts, and it is often the most significant element.

For a couple without children, the residue might pass to the survivor in the first instance, with substitute beneficiaries if the survivor does not survive by a defined period. A survivorship clause of 28 or 30 days is common. It prevents assets from passing back and forth between two estates after a shared accident or illness, and it can reduce administrative complication.

Substitute beneficiaries deserve particular attention. If both partners die, who should receive the estate? Friends, godchildren, nieces and nephews, a charity, or a combination? The answer should be recorded in the will, not left to the intestacy formula. Where several people are chosen, the shares should be stated clearly, and consideration given to whether a gift should lapse if a beneficiary dies first.

The residence nil rate band does not always follow

The inheritance tax landscape is less generous for some childless estates than it first appears. The residence nil rate band can provide an additional allowance where a main residence passes to direct descendants. Direct descendants generally means children, grandchildren, stepchildren and certain adopted or fostered relationships. Friends, siblings, nieces and nephews do not ordinarily qualify. A couple without children may therefore have the standard nil rate band, and any transferable allowance from a spouse or civil partner, but not the residence nil rate band.

That does not make inheritance tax planning impossible. It does mean the family home should not be assumed to be covered by an additional relief. Lifetime giving, charitable legacies and the careful use of available exemptions may all play a part. The right approach depends on the size and composition of the estate, and on whether the home is likely to be retained or sold.

Trusts for a chosen circle

Trusts can be useful where outright gifts are unsuitable. A discretionary trust allows trustees to decide how and when beneficiaries benefit, which may suit an estate where the chosen beneficiaries have different needs or where a surviving partner may need flexibility. A vulnerable beneficiary trust may assist where a beneficiary has a disability or lacks capacity. Trusts carry costs and administrative duties, however, and should not be used as a default solution.

Lifetime gifts can also shape the estate before death. The annual exemption, small gifts allowance and normal expenditure out of income rules may permit regular giving without immediate inheritance tax consequences. Larger gifts may fall outside the estate if the donor survives seven years, subject to tapering and any reservation of benefit. Records should be kept, and advice taken where the amounts are substantial.

Charity as a deliberate beneficiary

For some individuals without children, a charity may be a natural beneficiary rather than an afterthought. A charitable gift can be made as a fixed sum or as a share of the residue. Where at least 10% of the baseline estate is left to charity, the reduced rate of inheritance tax may apply to the rest. The relief is not a reason to choose a charity, but it can make a considered gift more efficient.

Who steps in when both partners die

The question of who steps in is practical as well as legal. Executors administer the estate; trustees manage any trust. Replacement appointments should be made in case the first choice cannot act. A letter of wishes can sit alongside the will to explain the reasoning behind beneficiary choices, although it is not binding.

Pensions and life assurance often fall outside the will. Nomination forms should be reviewed so that death benefits are directed as intended. Digital assets, from online accounts to photographs and cryptocurrency, should be addressed separately. Funeral wishes and any pet legacies should also be recorded.

Avoiding unintended heirs and disputes

Clear drafting reduces the risk of dispute, but it does not eliminate it. A dependant or cohabitant may be able to bring a claim under the Inheritance (Provision for Family and Dependants) Act 1975. Independent legal advice, a record of capacity and a reasoned will can all help. Where relationships are complex, it may be sensible to explain the plan to those most affected, rather than leave them to discover it after death.

A calm review for 2026

A childless estate should be reviewed periodically. Confirm that the will still names the intended beneficiaries, that substitute beneficiaries remain appropriate, and that pensions and insurance nominations match the will. Check that any trust remains properly administered. If a couple separates, or a chosen beneficiary dies, the plan should be updated promptly.

The default heir is rarely the person one would choose. For couples and individuals without children, a considered estate plan is an act of clarity: it says who mattered, who should benefit, and who should decide. That is a more honest legacy than a legal formula can provide.
