Law / Questions on Civil Wedding Ceremony in Poland- Do we get the certificate on the day? [25]

My fiance and I have booked a civil wedding ceremony in Lodz in May. I am Scottish, my fiance is Polish.

When would we receive our wedding certificate, is this given to us on the day or do we collect this at a later date?

Do we need to register the wedding in Poland after the ceremony or is this done automatically?

Are there any other formalities to take care of following the ceremony?

Trying to figure out the best date to fly back to Scotland following the wedding.

Thanks in advance for any advice given!
