The Oregon 45 21 form, officially known as the Voluntary Acknowledgment of Paternity Affidavit, plays a crucial role for non-married parents in establishing paternity in the state of Oregon. Effective from September 11, 2014, this form is designed for mothers who wish to acknowledge the father of their child when they are not married. It must be signed by both parents in the presence of a notary public, ensuring that the acknowledgment is legally binding. Importantly, the form can be completed outside of a hospital or birthing facility, but it must be filed within specific time frames to avoid additional fees. Parents should be aware that if the mother was married within 300 days prior to the child’s birth, her husband is presumed to be the father, regardless of biological ties, unless a court order states otherwise. The form also outlines specific conditions under which it becomes invalid, such as if either parent has relinquished parental rights or has signed an adoption consent. After filing, parents have a 60-day window to rescind the acknowledgment if they have doubts about the paternity. The process also includes important instructions on how to fill out the form correctly to avoid rejections, highlighting the necessity of completing all fields and ensuring no alterations are made. In essence, the Oregon 45 21 form is a vital document for establishing paternity, protecting the rights of both parents and the child involved.
