Asking on behalf of a friend at work who is in a right mess - quick question for those bright ladies with legal knowledge or experience - what are the likely custody rights of a married bloke whose wife has had an affair? If he has an email from her to her lover stating she slept with him and is only staying with her husband for the money, would he be able to throw her out and take main custody of the child owing to her unreasonable behaviour? I know how it would work if it were a woman in his position but this isn't so straightforward. All ideas welcome - he earns more than the wife, who is a school assistant, but is in no way rich hence the fact I'm asking for help here rather than suggesting a solicitor straight away. Thanks...
