Welfare benefit MC2

Hi. I have a small question about this. I am a bit confused. I started certified sick leave on 8th February after a minor operation. I was given a two week cert by my doctor and shall return to work on 22nd February. I filled in a MC1 application form on 14th February and submitted it. My question is - when do I fill in my INTERIM MC2 form ? Do I not bother with it and just fill in my FINAL MC2 form on the day that I return to work ? Any help would be appreciated thanks

Got clarification by ringing the Social Welfare office. They told me to submit both the interim MC2 and final MC2 to them on the day I go back to work. I just answered my own question just in case it comes up for someone else

The MC1 (purple form) should be completed from 8th Feb ( first day of illness). That covers the first week. MC2 (yellow form) should be completed on 15th (to cover 2nd week). To return to work on 22nd, a Final Cert (blue side of the MC2) should be completed on 21st.
