Naming Guardians: How to Protect Your Children in Your Will

Modern Legacy 5 min read Updated May 2026

If both parents die before their children turn 18, who steps in to raise them? Without a named guardian in your Will, that decision goes to a court — and the person appointed may not be who you'd have chosen. This is one of the most important things your Will can do.

For many parents, making a Will feels abstract — something to do "eventually." But there is one question a Will answers that nothing else can: if we are both gone, who raises our children?

The answer, without a Will, is whoever a court appoints. That person may or may not be who you would have chosen. The process is slow, distressing for everyone involved — and entirely avoidable.

What Is a Legal Guardian?

A guardian is someone who takes on parental responsibility for your children if both parents die before the children reach 18. This means making decisions about where they live, their education, their medical care — every significant aspect of their upbringing.

Guardianship is not the same as inheriting money. A guardian takes on the responsibility of raising your child, but the financial provision for the child should be handled separately through your Will — typically through a trust that the guardian can draw on.

Who needs to think about this

Any parent with children under 18. It doesn't matter whether you're married, co-habiting, or a single parent — if both parents are gone, a guardian is needed. And if you're a single parent with sole parental responsibility, this is even more urgent.

What Happens Without a Named Guardian?

If neither parent has named a guardian — or no Will exists at all — the court will appoint someone under the Children Act 1989. This is not a quick or simple process.

In the meantime, your children may be placed in temporary care while the court process unfolds. The person ultimately appointed might be a relative you'd have chosen — but it might not be. Extended family members may disagree. The process can become adversarial at precisely the moment your children need stability.

Common mistake

Many parents assume their parents or siblings would "obviously" step in. In law, no one has an automatic right to guardianship except a surviving parent with parental responsibility. Everyone else — grandparents, aunts, uncles — must apply to court.

Choosing the Right Guardian

There's no perfect formula. The right guardian is someone you trust — with your values, your parenting instincts, and your child's wellbeing in mind. Here are the questions most parents work through:

Age matters too. Naming an elderly parent as guardian for a newborn might seem natural but could become unworkable a decade later. Consider naming a backup guardian in case your first choice is unable or unwilling to act when the time comes.

Can You Name Two Guardians?

Yes — and for couples, it's common to name your partner's sibling or close friend as a joint guardian, or to name two people who will share responsibility. However, joint guardianship requires those people to agree on decisions, which can create friction. Think carefully about whether a joint arrangement is practical, or whether one primary guardian with a named backup is simpler.

What About the Other Parent?

If the other parent is alive and has parental responsibility, they automatically continue as the child's carer — your named guardian only becomes relevant if both parents are gone. If you are a single parent and the other parent does not have parental responsibility, naming a guardian is even more critical: there is no automatic fallback.

One more step: talk to them

Naming someone in your Will without telling them is a well-intentioned mistake. Make sure your chosen guardian knows, has agreed, and understands what you'd want for your children. It's also a good opportunity to tell them where your Will is kept, who your executor is, and any important wishes about your children's upbringing.

Guardians and Money: Keep Them Separate

A guardian's role is to raise your children — it isn't necessarily to control their inheritance. Many parents use a trust within their Will to hold assets for their children, with a separate trustee managing the money. This means the guardian focuses on parenting while a trusted person (or professional trustee) handles the finances — and avoids putting one person under pressure to manage both roles perfectly.

Without a trust, children inherit outright at 18 — which may or may not align with what you'd want. A Will-based trust lets you specify that funds are held until 21, 25, or another age you choose.

Review regularly

Circumstances change. The friend you'd trust with your children at 30 may have moved abroad, had their own family complications, or simply drifted from your life by 40. Review your guardian choice every few years and whenever your circumstances change significantly.
