I'm assuming you're talking about sex offender registration. While you do not *need* a lawyer to do this, it may be very prudent to hire one. Otherwise, you'll need to figure out all of the laws, forms, and procedures on your own, and devote your personal time to go to court. This can be a big headache.
Sex offender registration in Washington state is regulated by RCW 9A.44.142 if you were an adult when convicted, and 9A.44.143 if this was a juvenile offense. I have added links to those statutes below, and a link to the forms you would file here in Washington state. You will need to determine if your out of state conviction is the equivalent to a conviction in Washington state to see if you can petition to have you removed from registration. You also will need to research the law in the state where you got your conviction to see if your registration requirement can be terminated, or whether it may have already expired. I have done a petition for relief from registration for a client before, and it is more complicated than it looks. Courts are reluctant nowadays to remove registration unless they are sure you would not be a threat. You should contact an attorney rather than do this yourself, it will be worth the money.
This answer is for discussion purposes only, and does not establish an attorney-client relationship.
The reason only two lawyers answered this question in three days is because this is a very specialized field. If you no longer have to register, removal should be very simple----the people you report to will take you off of the list. However, the laws changed and most people who believed that they no longer had to register found that they had to register for life. In Maryland, one attorney took on the State and won and she was able to change the law back to the way ot was originally for all of those people who were forced to register for life after they thought that they were finished. Unfortunately, even she is struggling getting each and everyone of those individuals off of the registry. Bottom line----you can't mess this up. You need to find someone who knows how to deal with this specifically and there are not too many of us who do.
