Hello again, Alex, and thank you for clarifying that for me.
WA law does not typically recognize an unmarried father's parental rights
until they have been established by court order, so you do need to get a petition for parental rights filed as quickly as possible.
Under the circumstances you have described, a prosecutor would not typically pursue kidnapping charges against you since the mother
left the child in your care, but you could be forced to return custody of your child to the mother until you can get an order of custody.
It would be best to retain a local family law
attorney and file an ex parte petition for custody of the child since it appears the mother is unstable and may attempt to pursue kidnapping charges against you or retake custody of the child.
I hope this helps clarify the situation for you. Please remember to rate my service once you have all the information you need so I will be compensated for my time from the deposit you posted with this website. If you have any other questions, please ask me – I’ll be happy to respond. Thank you!
