Why This Decision Matters
This is the part of Will writing that people put off the longest. We get it. But the alternative to thinking about it is leaving a family court judge, a complete stranger, to decide who raises your children if the worst happens. That judge has never met your kids. They don't know your family.
That judge won't know your son hates loud houses or that your daughter has finally settled at her school after a rocky start. They'll do their best, obviously, but "their best" involves social worker assessments, court hearings, and what could be months of uncertainty for children who've just lost both parents.
A single line in your Will changes everything. You name a person. That person steps in. Done.
What's the Guardian's Role?
In practical terms, the guardian becomes the parent. Morning school run, dentist visits, homework battles, the whole lot. They also make the bigger decisions: which school, what medical treatment, how to handle religious questions.
The law formalises this through something called parental responsibility. Consent forms, passport applications, doctor's appointments, all legally theirs to handle. They're also expected to look after any property or money belonging to the child, although you can appoint separate trustees to deal with the financial side if you'd rather keep those roles apart.
One common worry: does the guardian have to pay for everything themselves? No. Life insurance payouts, any inheritance your children receive, savings you've earmarked for them, that's what covers their care. Your guardian looks after the children, not necessarily the chequebook.
Picking the Right Person
Forget trying to find someone perfect. You're looking for someone good enough across several dimensions at once.
Values come first, and not in a preachy way. Would your children's daily routine feel roughly familiar, or would everything be different? Think about attitudes to education, screen time, outdoor play, religion, discipline. You won't find a carbon copy of yourself, but a drastic mismatch in how the household runs would make a brutal transition even harder.
Then there's the question of capacity. There's a world of difference between "brilliant uncle at Christmas lunch" and "responsible for two teenagers every single day for the next eight years." Test the idea against real daily life, not the highlight reel. Younger relatives building careers, or older ones already managing health issues, might adore your children yet not be able to take them on practically.
Then there's distance. Picture a child who has just lost a parent and then has to leave her school, her friends down the road, and the only bedroom she has ever slept in. Adults tend to underrate how much that secondary upheaval matters. Local guardians have a genuine advantage here, though obviously family geography doesn't always cooperate.
Familiarity is the other big factor. Children who regularly sleep over at their grandparents' house, who know which cupboard the cereal lives in and have their own toothbrush in the bathroom, handle the transition far better than children landing with someone they see twice a year at weddings.
Both Parents, Same Guardian?
For couples who both hold parental responsibility, the guardian clause in your Will is a "both parents gone" provision. Hopefully it never activates. But agreeing on your choice together, and writing the same name into both Wills, means the plan is there if it's ever needed.
After a separation or divorce, things look different. Parental responsibility stays with the surviving parent no matter what the deceased parent's Will says. The guardian clause only wakes up if the second parent also dies, or in rare cases where a court intervenes. Remarried with kids from a previous relationship? Your current spouse has no automatic parental responsibility for those children, which often surprises people. A named guardian in your Will sorts that out cleanly and avoids a tangle of conflicting assumptions later on.
Can You Name Two Guardians Together?
Nothing stops you naming two people jointly. A solid pairing is two people who already run a household together and have experience with children of their own. The catch? Every parenting decision needs consensus between them, and if their own relationship breaks down in future, you've got a guardianship arrangement that no longer fits the reality on the ground.
An alternative is naming a primary guardian with a reserve who only steps in if the first person can't take the role. Same logic as backup executors: you're building in a safety net.
Appoint guardians in your Will
Our service prompts you to name guardians for each child under 18 — so there is never any doubt about who looks after them.
The Consequences of Not Naming Anyone
Without a guardian in the Will, the local authority can temporarily take charge while the courts work out what to do. Different relatives may apply for a Child Arrangements Order at the same time, each convinced they're the best choice. Grandparents, uncles, godparents, ex-partners, all pitching their case to a judge.
These proceedings take weeks at minimum, often months. During that window, your children live in limbo. No child should go through that kind of uncertainty after losing a parent, not when a few lines in a Will could have settled the question before it ever arose.
Having the Conversation
Pick somewhere relaxed for the conversation. A walk or a quiet lunch works well. Explain why you chose them, how the day-to-day would look, and what financial support you have arranged. Then give them breathing room. A fortnight to think isn't unreasonable for a question this big.
You might get an immediate yes from someone who's already thought about it. You might get a careful pause. Sometimes the answer will be a straightforward "I don't think I could do it." That stings, but someone who knows their own limits is being more honest with you than a reluctant yes ever would be. A guardian who accepted reluctantly is not going to be the rock your children need.
Next Steps
Our online Will-writing process has a dedicated guardians section. You add your children's details, name a guardian, and optionally add a backup. The whole thing takes a couple of minutes and is, without exaggeration, one of the most important things you can do as a parent.
Frequently Asked Questions
At what age does a child no longer need a guardian?
Guardianship ends when the child turns 18. After that, they're a legal adult and make their own decisions.
Can grandparents be named as guardians?
Yes. Age and health are worth considering practically, but there's no legal barrier to naming a grandparent. Many families do, especially when the grandparents are actively involved in the children's lives.
What if my chosen guardian's circumstances change?
You can update your Will at any time. If your guardian moves abroad, becomes unwell, or their situation changes significantly, write a new Will naming a different person.
Can the guardian be someone who lives abroad?
Legally, yes. Practically, it means your children would likely relocate to another country, which is a big disruption. Courts would consider the children's welfare, including stability and continuity, if the arrangement were ever contested.
Does the guardian have to be a relative?
Not at all. Close family friends, godparents, or anyone you trust can be named. What matters is the quality of the relationship and the person's willingness and ability to take on the role.
