For parents with minor children, guardianship is often the primary reason to have a will at all. Without a named guardian, a court decides who raises your children — weighing the petitions of relatives who may have competing interests and very different values from yours.
This is not a comfortable thing to think about. That discomfort is exactly why most parents never make the decision.
What a guardian does
A guardian of the person — which is what most people mean by "guardian" — is responsible for your child's day-to-day life: where they live, where they go to school, their medical care, their upbringing.
This is distinct from the trustee who might manage any money you leave for your children. You can name the same person for both roles, or different people. Separating the roles is sometimes wise — the best parent figure isn't always the best money manager.
What to consider when choosing
Values alignment. More than almost anything else, you want someone who will raise your children with values similar to your own — about education, religion, family, how to handle conflict, what matters in life.
Relationship with your children. A guardian who already has a strong relationship with your kids is better than a technically more qualified stranger. Stability and attachment matter.
Practical circumstances. Consider their age, health, stability, location, and whether they have children of their own. Someone who is 70 years old may not be the right choice for a two-year-old, even if they're the person you trust most.
Willingness. Ask. Don't assume. Guardianship is a profound commitment. Most people are honored to be asked and will say yes — but they should say yes knowingly, not be surprised after you're gone.
Financial situation. Your guardian doesn't need to be wealthy — that's what life insurance and a trust are for. But someone in significant financial distress may face conflicts of interest when managing money on your children's behalf.
What if there's no perfect choice?
There rarely is. Most parents find themselves choosing between imperfect options — a sibling who's great with kids but lives across the country, a local couple with different values, parents who are wonderful but aging.
Choose the best available option, not a hypothetical perfect one. A good-enough guardian named in a will is far better than no guardian and a court fight.
You can also provide guidance in a letter of instruction — a private document that accompanies your will and explains your wishes for your children's upbringing in detail. A guardian isn't legally required to follow it, but most people who love your children will want to understand your intentions.
Always name an alternate
Your first choice might predecease you, become seriously ill, or decide they aren't able to take on the responsibility. Always name a backup.
If both your named guardian and alternate are unavailable, the court will appoint someone. The more guidance you've given in your will and supporting documents, the better that process goes.
What happens to the guardian's finances?
Naming a guardian doesn't obligate that person to fund your children's upbringing out of their own pocket. You provide for your children through life insurance, savings, and your estate. Your will (or a trust) can specify that a portion of your estate is held for your children's benefit and used for their care, education, and support.
If the amounts are significant, a trust with a trustee who is different from the guardian can be a useful structure — the trustee approves expenditures while the guardian handles day-to-day parenting.
Review it as your family changes
The person who is the right guardian for a newborn may not be the right guardian for a teenager. Relationships change, people's circumstances change, and your children's needs change. Review your guardianship choice whenever you review your will — after each major life event, and at minimum every few years.
