Considering the fact that you are athesist, therefore it would be impossible for you to get married in church. So you have to contact your county office and ask there for marriage department. there you have to take the appointment and also according to your nationality they will ask you for specific documents to submit. once you will get the date you can to the same office with witness and guest and ofcourse your wife :):):) and thats all :)
hope this information will be enough for you to start this process :)
Thank you for your reply.
Do you think it would possible to actually remarry and sign the book, and get a polish certificate.
Would be nice to do for my wife's familly.
