A few years ago, the WA Supreme Court held that a lifetime restraining order is likely unlawful. The courts can still issue lifetime restraining orders but only in very specific circumstances.
You can review the specific facts with your attorney to see whether you can ask the court to vacate the order from 20 years ago.
If you and the alleged victim have not had any problems with each other in the last 20 years, you may have a very good chance of having that order vacated.
I agree with the previous responses. Lifetime restraining orders are very disfavored. Traditionally, both parties can move the court jointly for the release of a restraining order. Consult an attorney about your specific order and circumstances.
