Of everything a will can do, this clause matters most and gets discussed least. If you have children under 18 and both parents die without appointing guardians, nobody automatically steps in. Grandparents have no automatic right. Godparents have none at all. A family court decides, months later, guided by social services reports, choosing between whoever applies. A single clause in your will replaces all of that with your own decision.
How guardianship appointments work
Under section 5 of the Children Act 1989, a parent with parental responsibility can appoint a guardian in writing, and a will is the standard place to do it. The appointment takes effect only when no parent with parental responsibility survives. If you die and the other parent is alive with parental responsibility, they simply continue raising the children; your named guardian waits in reserve. This is why couples usually name the same guardians in both wills, so the appointment holds whichever order events happen in.
One nuance worth knowing: a father who was never married to the mother and is not on the birth certificate may not have parental responsibility automatically. If that describes your family, it affects both who can appoint and what happens on a death, and it is exactly the kind of detail a solicitor review should check.
How to actually choose
There is no perfect guardian, only trade-offs weighed honestly. The questions that earn their place:
- Values and parenting style: who would raise them closest to the way you would?
- Relationship: do your children already know and love them?
- Age and energy: your parents may be wonderful, and seventy-five when your youngest hits fifteen
- Location: moving schools, friends and country is a second upheaval on top of the first
- Their own family: how do your children fit alongside their cousins, practically and emotionally?
- Willingness: this is a two-decade commitment; ask them properly, in private, before naming them
Separate the children from the money
Guardians raise the children; trustees manage whatever you leave for them. The two roles can be the same people, but they do not have to be, and separating them has quiet advantages: it lightens the guardian’s load, adds a second pair of eyes on spending, and removes any awkwardness when the guardian needs money from the trust for school shoes and skiing lessons. Your will can also let trustees release funds to help guardians directly, an extension, a bigger car, so that taking in your children never costs the people who did it.
Always name a backup
Guardians age, move abroad, divorce and change. Name a substitute guardian in the will, and write the private detail, schooling hopes, faith, contact with each side of the family, in a letter of wishes that sits alongside it. The letter binds nobody, which is exactly why you can update it every year without touching the will.
Keep it current
The guardian you would choose at your child’s birth is not always the right answer at ten. Revisit the appointment at each big life change, and update the will when the answer changes. With Willful, guardianship is a built-in step of the will interview whenever you have children under 18, the wording is checked by an SRA-regulated solicitor, and changing it later never requires starting from scratch.
