Appointing a Guardian in Your Will: Why It Matters More Than You Think

Ask any parent what they most want from a will and the answer is almost always the same: they want to know their children will be looked after. Yet the vast majority of parents in the UK have never formally named a guardian in a legal document. That means if both parents were to die, a court — not the family — would decide who raises their children.

What Is a Guardian?

A guardian is a person appointed to take on parental responsibility for a child under the age of 18 after the death of their parents. Under the Children Act 1989, a guardian can be formally appointed by a parent in their will. This appointment becomes legally effective on the death of the last surviving parent with parental responsibility.

A guardian steps into the role of parent: making decisions about where the child lives, their education, their healthcare, and their general welfare until they reach adulthood.

What Happens Without a Named Guardian?

Without a guardian named in a valid will, there is no automatic arrangement. Relatives may assume they will step in — but their assumption has no legal force. Instead, the court decides who takes responsibility for your children, weighing up competing applications from family members, considering the child's welfare, and potentially conducting a process that is slow, contested, and deeply distressing for everyone involved.

Even in straightforward cases, the absence of a named guardian adds legal process to what is already the worst possible situation. Your children need certainty. A guardianship clause in your will provides it.

Who Can Be Appointed as Guardian?

Any adult can be named as a guardian. There are no formal qualifications — but your choice should be someone who:

• Shares your values and would raise your children as you would wish
• Has the capacity and willingness to take on the role (always ask them first)
• Is likely to be able to care for the children for the duration of their minority
• Has a good existing relationship with your children

You can also name a substitute guardian — someone who steps in if your primary choice is unable or unwilling to act. This belt-and-braces approach is strongly recommended and is included as standard in every Wills Assured document.

Guardianship and Financial Provision

Appointing a guardian handles the question of who cares for your children — but not how that care is funded. A well-structured will combines the guardianship clause with trust provisions that hold and distribute your estate for the benefit of your children until they reach adulthood. This ensures the person raising your children has access to the resources they need to do so.

Wills Assured includes a full Trust for Children in every will where minor children are named, specifying the age at which each child's share vests and giving trustees discretion to apply funds for the child's maintenance, education, and advancement in the interim.

Is a Guardianship Nomination Legally Binding?

A formal appointment in a will is strong legal evidence of the parent's wishes and will be given significant weight by a court. However, a court can in theory override it in exceptional circumstances where the welfare of the child requires it. In practice, a clearly named guardian in a valid will is almost always followed — it is the absence of a named guardian that leads to uncertainty and dispute.
