In short

  • You can leave your entire residuary estate to your children, in equal or unequal shares
  • Children inherit outright at 18 unless you set a later age in your will
  • A per stirpes substitution protects grandchildren if a child dies before you
  • A surviving spouse or partner with no automatic entitlement should be considered separately

Whether you are single, divorced, widowed or simply want your estate to pass directly to the next generation, leaving everything to your children is a straightforward and common choice under a will. English law gives you the freedom to decide the shares, the ages at which they inherit, and what happens if a child is no longer alive when you die.

This guide sets out how to structure a will leaving everything to your children, the inheritance age options available, and how to protect a child's share if they die before you.

Leaving your residuary estate to your children

Most wills that leave everything to children do so by naming the children as beneficiaries of the residuary estate, which is everything left after debts, funeral expenses and any specific gifts have been dealt with. You can specify equal shares, for example one third each to three children, or unequal shares if you have reasons for treating children differently.

This is one of the simplest and most common structures in a will, and it works well provided the children are named clearly and you have thought through what happens if one of them is not alive when you die.

Choosing an inheritance age

If your will leaves money to children with no age specified, they are entitled to inherit outright once they turn 18. Many parents feel this is too young for a significant inheritance and instead choose a later age, commonly 21 or 25, during which the money is held on trust by the executors or trustees you appoint.

Trustees can generally use income or capital for a child's maintenance, education or general benefit before the chosen age is reached, so choosing 21 or 25 does not prevent money being used sensibly in the meantime. There is no fixed rule; it depends on how you view your children's readiness and the size of the estate.

  • 18: simplest option, but a significant sum is received with no restrictions
  • 21: a common middle ground for moderate estates
  • 25: often chosen for larger estates or where more maturity is wanted before full access

Equal or unequal shares

Many parents choose equal shares between children as the simplest and least contentious option. However, you are free to leave unequal amounts if circumstances justify it, for example one child having already received significant financial help, or a child with additional needs requiring more support.

If you do decide on unequal shares, it is worth explaining your reasoning in a separate letter of wishes, since an unequal will can sometimes prompt questions or disputes between children after your death, and a clear explanation can reduce the risk of that.

Protecting a child's share with substitution

It is important to state what happens if a child dies before you. A per stirpes, or substitutional, gift means that if a child has already died, their own children (your grandchildren) step into their place and inherit their parent's share, rather than that share passing only to your surviving children or falling into intestacy.

Without this kind of clause, a deceased child's share could end up being redistributed in a way you did not intend, particularly if they have left children of their own who you would want to benefit.

What about a spouse or partner

If you are separated, divorced, or have no spouse or partner, leaving everything to your children is often the natural choice. If you do have a spouse or partner and want to provide for them as well as your children, you will need to think about how the two interests are balanced, for example an outright gift to your spouse, a life interest trust, or a split of the estate between them.

My Posh Will's guided online process helps you work through these choices clearly, whether you are leaving everything to your children alone or balancing that against provision for a partner.
