Can Grandparents Get Guardianship of Grandchildren?

When parents cannot safely care for their children, grandparents are often the ones who step forward. In Washington, a minor guardianship can give a grandparent the legal authority to raise a grandchild, but the court applies specific rules before it will grant one.

Yes, With the Right Legal Basis

Grandparents can absolutely seek and obtain guardianship of a grandchild in Washington. The court does not hand out guardianships automatically based on the family relationship, though. A grandparent has to fit the situation into one of the legal grounds the statute recognizes, and the arrangement has to serve the child. Understanding those grounds up front tells you whether a guardianship is realistic in your circumstances and what you will need to show the court.

The Legal Standard for a Minor Guardianship

Washington's rules for guardianship of a child live in chapter 11.130 RCW. The key provision is RCW 11.130.185, which sets the basis for appointing a guardian for a minor. Under that statute, the court may appoint a guardian for a child who does not already have one only if two things are true. First, the appointment must be in the child's best interest. Second, at least one of three specific conditions must exist: every parent of the child, after being fully informed of what guardianship means, consents; all parental rights have been terminated; or there is clear and convincing evidence that no parent is willing or able to exercise parenting functions as defined in RCW 26.09.004.

Those three paths cover very different family situations. The consent path fits a family where the parents recognize they cannot parent right now and agree that grandma or grandpa should step in, perhaps because of illness, deployment, incarceration, or a treatment program. The terminated-rights path applies where a court has already ended the parents' legal rights. The third path is the contested one. It allows a grandparent to seek guardianship even without parental consent, but only by proving, with clear and convincing evidence, that no parent is willing or able to actually parent the child. That is a demanding standard, deliberately so, because it can override a parent's role.

Best Interest Is Always Required

Notice that best interest is not optional in any of these paths. Even if a parent consents or a ground is otherwise met, the court still must find that the guardianship serves the child. Judges look at stability, safety, the child's relationship with the grandparent, the home environment, and the child's needs. For many grandparents, this is the easier part to demonstrate, because they have often already been the child's steady caregiver. But it still must be shown, and the court makes an independent judgment rather than simply deferring to the family's preference.

How a Grandparent Starts the Process

The process begins by filing a petition. Under RCW 11.130.190, a person interested in the welfare of a minor, which certainly includes a grandparent, may petition for appointment of a guardian for the child. The petition asks for a range of information: the child's name, age, and where the child lives or would live; the names and addresses of the child's parents; the identity of anyone who has had primary care or custody of the child during recent years; the legal basis for the guardianship; and the proposed guardian and why they should be chosen. The statute also asks the petitioner to set out the factual reasons the guardianship is sought and why it would be in the child's best interest in a separate supplemental declaration.

Because the petition must name the parents and identify recent caregivers, it naturally surfaces the very facts the court needs to test against RCW 11.130.185. A grandparent who has been the child's day-to-day caregiver for a stretch of time, for example, will note that history in the petition, and it becomes part of the picture the court weighs.

What to Expect After Filing

Once the petition is filed, the parents and other interested parties are entitled to notice and an opportunity to respond, because a guardianship affects a parent's fundamental role. If the parents consent, the case can move more smoothly toward a hearing where the judge confirms that consent was informed and that the arrangement serves the child. If a parent objects, the case becomes contested, and the grandparent must be prepared to meet the clear and convincing evidence standard that no parent is willing or able to exercise parenting functions. The court may look closely at the parents' current circumstances, their history with the child, and whether their inability to parent is genuine and ongoing rather than temporary.

It is also worth understanding what a minor guardianship is and is not. A guardianship gives the grandparent legal authority to make decisions and care for the child, but it is generally not the same as adoption, which permanently ends the parents' legal relationship with the child. A guardianship can provide the stability a child needs now while leaving room for a parent to work toward resuming care if their situation improves. For many Snohomish County families, that flexibility is exactly what makes a guardianship the right tool rather than a more permanent step.

Common Questions Grandparents Ask

Grandparents frequently ask whether they can get guardianship if the parents are simply struggling but not unfit. The answer depends on the facts. If the parents recognize the difficulty and consent, the consent path may be available. If they do not consent, occasional struggles usually will not meet the high bar of clear and convincing evidence that no parent is willing or able to parent. Another common question is whether both grandparents can serve together. Washington law allows co-guardians, so a grandmother and grandfather can seek appointment jointly if that arrangement serves the child.

Getting Guidance Before You File

Minor guardianship cases sit at the intersection of guardianship law and family law, and the outcome often turns on which legal path fits your family and how well the petition presents the facts. A well-prepared case that clearly ties the child's circumstances to the statutory grounds gives the court what it needs to act, while a rushed or incomplete filing can stall or fail.
