In Washington State, grandparents and other concerned adults may pursue third-party custody in Washington or guardianship of a child when both parents are found unfit or unable to provide a safe and stable home. Following recent changes in state law, this process requires submitting a Minor Guardianship Petition, most commonly initiated by grandparents or close family members. To succeed, the petitioner must demonstrate with clear and convincing evidence that the parents are incapable of meeting key parenting responsibilities, such as ensuring daily care, education, and financial support. The legal process involves preparing a detailed petition, providing notice to parents and relatives, and presenting compelling evidence at a court hearing. While the court may grant guardianship to protect the child’s best interests, parents generally retain certain rights and can later seek to alter or end the guardianship, underscoring the importance of skilled legal representation at every step.
