The law on domestic abuse in Scotland was formalised in the Domestic Abuse (Scotland) Act 2018, which created a new offence of engaging in a course of abusive behaviour towards a partner or ex-partner. The behaviour does not have to be violent; it also covers psychological and emotional abuse. If abuse is also directed towards children or they are adversely affected by it, this will be an aggravating factor and will be reflected in any sentence imposed.
The authorities take a firm approach to investigating and prosecuting domestic abuse allegations. However, sometimes what is simply a heated argument can be interpreted as domestic abuse. For these reasons, it is essential that you instruct an experienced criminal defence lawyer to represent your position and point of view.
