What do I do at the end of the match, and who signs the sheet?

At the end of the match the scorer:

1. Records the final result.
2. In the case of a protest, and with the previous authorization of the first referee, writes (or permits the team or game captain to write) a statement about the incident being protested on the score sheet.
3. Signs the score sheet him or herself, before obtaining the signatures of the team captains and then the referees.

The assistant scorer signs the Libero control sheet and submits it for checking, and also signs the score sheet. The second referee and first referee each check and sign the score sheet at the end of the match.
