Estate Planning for Young Adults UK (2026): Why You Need a Will and LPA in Your 20s and 30s

Yes — the assumption that you don't need a will until you are older, own property, or have significant assets is one of the most common and costly estate planning myths. Here is what happens to young adults without a will: (1) COHABITING PARTNERS GET NOTHING UNDER INTESTACY: the most significant risk for young adults. If you are living with a partner but are not married or in a civil partnership, and you die without a will, your partner inherits NOTHING under the intestacy rules (Administration of Estates Act 1925). Your estate goes to your parents, or your siblings, or even more distant relatives — depending on who survives you. Your partner's only legal remedy is an Inheritance Act 1975 claim in the courts — expensive, slow (6–18 months), and uncertain. A will solves this in 30 minutes; (2) YOUR PARENTS MAY INHERIT INSTEAD OF YOUR PARTNER: under intestacy, if you have no spouse/civil partner and no children, your estate goes to your parents in equal shares. If you are in a long-term cohabiting relationship, your partner receives nothing; your parents (even if estranged) receive everything. A will directs your estate to whoever you actually want; (3) IF YOU HAVE CHILDREN: if you have minor children, your will is the only place to appoint a guardian — the person who would look after them if both parents die. Without a guardian appointment, a court decides — potentially appointing someone neither parent would have chosen; (4) YOUR DIGITAL ASSETS AND PERSONAL PROPERTY: without a will, your executor (family member under intestacy letters of administration) has no guidance on what to do with your online accounts, personal property, or digital assets. A will (supplemented by a digital legacy document) gives clear instructions; (5) YOUR ESTATE HAS MORE VALUE THAN YOU THINK: a 28-year-old with a death-in-service benefit of £100,000 (4× salary), a small pension, a car, and savings of £15,000 has a meaningful estate. Without a will, none of it goes where they would want under intestacy — unless they happen to have no spouse or children and their parents are their intended beneficiaries anyway; (6) MARRIAGE REVOKES YOUR WILL: if you made a will and then got married or entered a civil partnership without updating it, the marriage revoked the will (Wills Act 1837 s.18). You are now intestate. Make a new will after any major life event.

An LPA is not just for elderly people. Accidents, illness, and incapacity can happen at any age — and without an LPA, the consequences for a young adult can be devastating: (1) ROAD ACCIDENTS AND SUDDEN ILLNESS: if you are involved in a serious road accident, or suffer a stroke, a brain injury, or a cardiac arrest that leaves you temporarily or permanently incapacitated, no one has legal authority to manage your finances or make healthcare decisions on your behalf — not your parents, not your partner, not your best friend; (2) YOUR BANK ACCOUNTS ARE FROZEN: a sole bank account is frozen on notification that the account holder lacks mental capacity. Without an LPA, your rent cannot be paid; your car insurance will lapse; your phone contract cannot be cancelled; your salary cannot be accessed. The only solution is a Court of Protection deputyship application — 6–12 months, £3,000–£6,000+, and the court appoints who it thinks is appropriate (which may not be who you would choose); (3) YOUR PARENTS HAVE NO AUTOMATIC AUTHORITY: many young adults assume their parents have authority to act for them. They do not — at 18 or over. Mental capacity law does not recognise a parental right to manage an adult child's affairs. Similarly, a partner (whether long-term or married) cannot access a sole account without an LPA; (4) A PROPERTY AND FINANCIAL AFFAIRS LPA (LP1F): authorises a chosen person to manage your bank accounts, bills, investments, and property if you lose capacity. Critically, it can be restricted to 'only when I lack capacity' — so there is no risk of the attorney accessing your accounts while you are healthy; (5) A HEALTH AND WELFARE LPA (LP1H): authorises a chosen person to make decisions about your medical care, daily routines, and in extreme cases, whether to refuse life-sustaining treatment. Without it, medical teams make decisions based on clinical judgment and consultation with family — but family members have no legal right to override a medical decision; (6) COST AND TIMING: each LPA costs £82 to register with the OPG (reduced/exempt for those on certain benefits); making it takes 1–2 hours online at make-an-lpa.service.gov.uk. The registration process takes 8–20 weeks — register well before you think you might need it.

A complete estate plan for a young adult does not need to be expensive or complex. In priority order: (1) PRIORITY 1 — MAKE A WILL: costs £35 with a WillSafe UK DIY kit; approximately 30–60 minutes. At minimum, the will should: name an executor (trusted adult — parent; partner; friend); name residuary beneficiaries (who gets everything); appoint a guardian if you have minor children; include a digital assets clause. Review after any major life event (marriage; divorce; children; new property); (2) PRIORITY 2 — UPDATE PENSION NOMINATIONS: contact every pension provider and complete or update the expression of wishes form. This is free and takes 10 minutes per pension. DC pension death benefits pass outside the estate — directly to whoever is nominated. An outdated nomination (to an ex-partner; a deceased parent) means the wrong person receives a potentially large sum; (3) PRIORITY 3 — CHECK DEATH IN SERVICE: contact your employer's HR department. Most employees have death in service cover (2x–4x annual salary). Check who is nominated to receive the payment. Update the nomination form. This money passes outside the estate and outside probate to the nominated person; (4) PRIORITY 4 — MAKE AN LPA: register a Property and Financial Affairs LPA. Consider registering a Health and Welfare LPA as well — especially if you have strong views about medical treatment. Apply online at make-an-lpa.service.gov.uk. Pay the £82 OPG fee per LPA; (5) PRIORITY 5 — WRITE A DIGITAL LEGACY DOCUMENT: separate from the will, list your online accounts, passwords (stored securely), social media preferences (memorialise/delete), and cryptocurrency if held; (6) PRIORITY 6 — LIFE INSURANCE IF DEPENDANTS: if you have a partner, children, or a jointly owned mortgage, get life insurance written in trust. The policy pays outside the estate — IHT-free, no probate — directly to the trust beneficiaries; (7) PRIORITY 7 — REVIEW PERIODICALLY: set a calendar reminder to review everything every 3–5 years or after each major life event. A will takes under an hour to update; a pension nomination takes 10 minutes. Do not let these become outdated.

For most young adults in England and Wales, inheritance tax is not a current concern — but it is worth understanding so you are not caught out as your estate grows: (1) THE IHT THRESHOLD: IHT (40%) applies on estates above the nil-rate band (£325,000 per person; frozen to April 2030) plus the residence nil-rate band where applicable (£175,000 if a qualifying home passes to direct descendants). A 28-year-old with £15,000 in savings, a pension, and a £30,000 death-in-service benefit is very unlikely to have an IHT liability; (2) DC PENSIONS OUTSIDE THE ESTATE (TO APRIL 2027): DC pension funds currently pass outside the IHT estate. From April 2027 (Finance Act 2024), unused DC pensions will enter the estate — this matters more as pension values grow with age; (3) WHERE IHT STARTS TO MATTER FOR YOUNGER PEOPLE: (a) Inheriting property: if you receive a large inheritance in your 20s or 30s that includes property, your own estate can suddenly exceed IHT thresholds; (b) Death in service of a high earner: a salary of £100,000 with a 4× death in service benefit creates a £400,000 payout — combined with savings and property, this may exceed IHT thresholds; (c) Jointly owned property purchased early: if you buy a house with a partner in your 20s and it appreciates significantly, the IHT threshold may be relevant sooner than expected; (4) SIMPLE IHT PLANNING FOR YOUNG ADULTS: (a) Write life insurance in trust — costs nothing extra and removes the policy payout from the estate; (b) Ensure pension nominations are correct — the beneficiary receives the pension directly, outside the estate; (c) Make use of the annual gift exemption (£3,000/year) and small gifts exemption (£250/person/year) if gifting to family; (d) Start to understand PETs — outright gifts are free of IHT if you survive 7 years; (5) IHT IS A FUTURE CONSIDERATION: for most young adults, the priority is to protect their family from intestacy and incapacity — not IHT planning. IHT becomes a live concern at estates of £500,000+ and can be addressed incrementally as the estate grows.

If a young person in England and Wales dies suddenly — in a road accident, for example — without a valid will, the outcome depends entirely on the Administration of Estates Act 1925 intestacy rules. The most common scenarios: (1) YOUNG ADULT, NO PARTNER, BOTH PARENTS ALIVE: entire estate passes to parents in equal shares. If the parents are separated, each receives 50%. The estate includes: solely owned bank accounts; investments; personal property; car; any shares or savings. If there is a death-in-service benefit, it passes separately to the nominated beneficiary (or the employer's trustees exercise discretion if there is no nomination); (2) YOUNG ADULT, COHABITING PARTNER, NO CHILDREN: partner receives NOTHING under intestacy. Parents take the entire estate. If no parents, siblings take the estate. The partner's only remedy is an Inheritance (Provision for Family and Dependants) Act 1975 claim — within 6 months of probate — which requires proving financial dependency or cohabitation for 2+ years before death. Success is not guaranteed; costs are significant; (3) YOUNG ADULT, MARRIED, NO CHILDREN: spouse takes the entire estate (no statutory legacy restriction applies where there are no children). This is the same as the simple will case for most couples; (4) YOUNG ADULT, MARRIED, CHILDREN: spouse takes personal chattels + statutory legacy (£322,000 in 2026) + 50% of residue. Children take the other 50% — held on statutory trust until age 18; (5) YOUNG ADULT, CHILDREN BUT NO PARTNER: children take the estate equally. If under 18, the estate is held on statutory trust; if no surviving parent has parental responsibility and can act as administrator, the court appoints a guardian for the administration; (6) THE PRACTICAL CHAOS OF DYING WITHOUT AN LPA ALONGSIDE A WILL: if the young person is incapacitated (not dead) — in a coma after an accident — there is also no LPA. Parents or partner cannot access bank accounts or make medical decisions without a Court of Protection deputyship application. A will does not help with incapacity — that is what the LPA is for. Both documents are needed, and together they take an hour and cost under £200.
