Trusts in plain English: what they are and when families use them

Say "trust fund" and people picture dynasties and Swiss lawyers. In reality, a trust is a simple and rather elegant idea that ordinary families use all the time — often without realising it (most life insurance in trust, and every will with provisions for young children, involves one).

What a trust actually is

A trust separates the ownership of an asset from the benefit of it. Three roles:

• The settlor gives the asset away into the trust.
• The trustees legally own and manage it, bound by duties to act in the beneficiaries' interests.
• The beneficiaries are the people the asset is held for.

That's the whole trick: you can give something away (helpful for IHT), without handing a 19-year-old a cheque (helpful for sanity), while keeping trusted people in control of the timing.

The two main flavours

Bare (absolute) trusts. The simplest form: the beneficiary is fixed and, once adult (18 in England and Wales), can demand the assets. Tax is generally assessed on the beneficiary, which can be efficient. The trade-off is inflexibility — you can't change your mind about who gets what.

Discretionary trusts. The trustees have discretion over which of a class of beneficiaries receives what, and when. Maximum flexibility and protection — nothing is "owned" by any beneficiary until the trustees decide, which shelters the assets from beneficiaries' divorces, creditors and immaturity. The price is a heavier tax regime: transfers in above the nil rate band face an immediate 20% charge, the trust pays periodic and exit charges, and income and gains inside the trust are taxed at top rates. Flexibility is bought with tax.

Where families actually use trusts

Life insurance in trust. Free to set up, keeps the payout outside your estate for IHT, and pays your family within weeks rather than waiting months for probate. If you have life cover not in trust, this is often the easiest estate-planning win available.

Providing for children. Wills routinely create trusts so that money is held for children until a sensible age, managed by guardians or trustees in the meantime.

Protecting against remarriage and bloodline concerns. Will trusts can ensure a surviving spouse is provided for during their lifetime while guaranteeing the capital ultimately passes to your children — a common concern in second marriages.

IHT planning with access needs. Specialist arrangements — loan trusts (you lend rather than give, keeping access to your capital while growth accrues outside your estate) and discounted gift trusts (you retain a right to fixed withdrawals while gifting the rest) — solve the classic dilemma of wanting to reduce IHT without fully letting go of the money. These are genuinely useful and genuinely complex: advice territory.

Vulnerable beneficiaries. Trusts for disabled or vulnerable people can provide lifelong support without jeopardising means-tested benefits, with favourable tax treatment.

The admin reality

Modern trusts come with paperwork: most must be registered on HMRC's Trust Registration Service, trustees have legal duties around record-keeping and investment, and the tax returns can be fiddly. None of this is a reason to avoid trusts where they fit — but it is a reason to set them up properly and know what the trustees are signing up for.
