Thanks for your question. I am a solicitor in Scotland. Your sister should see a criminal lawyer who may be able to have a word with the procurator fiscal to see if he would be prepared to deal with this by way of a warning or a fixed penalty notice on the basis that a conviction could affect the family unit. However, it is entirely up to the PF what steps he takes and if this was a bad assault he may decide that the case has to be prosecuted in the general public interest given the "zero tolerance" approach to domestic violence in Scotland. However, she can try even if there are no guarantees, and I suggest she goes to see a solicitor first thing on Monday. I hope that helps. Please leave a positive rating so that I am credited for my time.
