Neighbour dispute over laundry on washing line leaves one man facing homelessness and another divorced after High Court battle Clive Frost, 59, lived in the flat above Andrew Kemp, 44, in Brighton Mr Frost has won £2,500 in damages for defamation after 18-month fight Mr Kemp forged an objection email against Mr Kemp's planning application Now Mr Frost and his wife are getting divorced because of the stress A neighbourly dispute involving forgery and flying laundry has left one man facing homelessness and another man facing divorce. The argument between teacher Andrew Kemp and photographer Clive Frost came to a head at the High Court yesterday, with Mr Frost awarded £2,500 damages for defamation after his neighbour forged a complaint to the council. Now Mr Kemp, who apologised 'unreservedly' for his behaviour in court, is facing an estimated £20,000 legal costs bill and told the judge it could force him to sell his home. The row escalated in 2011 when Mr Frost, who lived with his family above Mr Kemp's flat, applied for planning permission for a roof terrace. Teacher Andrew Kemp pictured yesterday outside the High Court in London. His neighbour Clive Frost successfully sued him for defamation after Mr Kemp forged an objection to a planning application Mr Kemp, 44, was determined that the application would not succeed and filed an objection with the council as well as sending another objection pretending to be a female neighbour. Mr Frost, 59, sued his neighbour for defamation and malicious falsehood in relation to the two emails he sent to local authority planners. Yesterday he won his case and damages after an 18-month court battle. But the argument has cost him his marriage. Mr Frost and his wife Yamila are getting divorced because of the strain the row with their neighbour has put on their marriage, he said. The court heard that the pair had been at each other's throats for years. Mr Kemp claimed that his neighbour held noisy late-night parties and that washing from Mr Frost's line blew into his garden. Mr Frost said his neighbour had made the haven of his home 'a nightmare'. Judge Patrick Moloney QC awarded Mr Frost £2,500 damages, calling the roots of their disagreement 'trivial' and the dispute 'sad and regrettable'. Mr Frost, a father of one, earlier told the judge that the row has caused him 'an untold amount of distress'. He said: 'Nobody has come up to me in the street and said "you are the guy who makes a lot of noise on his roof terrace." Clive Frost told a judge at the High Court that the row with Mr Kemp had cost him his marriage The disagreements between my wife and I over me bringing the court case against him, led to other disagreements. Mr Kemp has been a catalyst of that situation. The consequences of the action brought against Mr Kemp, and his lies over 18 months, has been to create a lot of other issues between me and my wife. Our relationship has become incredibly difficult. Mr Kemp has interfered in my relationship between me and my wife. He told the judge: 'I make a point of not going out of my door if Mr Kemp is likely to be there because I don't want to have any face-to face contact with him. I bought a flat in Brighton thinking I was buying a home for me and my family, but my haven has became a nightmare because of the gentleman living downstairs. Mr Kemp, in a statement which he read in court, said: 'I now wish to admit my wrongdoing and apologise unreservedly to Mr Frost for what I did and the harm and distress it has caused him. I accept that I must pay him compensation and costs. The ruling over costs was adjourned after Mr Frost indicated he would be seeking £20,000 from Mr Kemp. Mr Kemp said: 'There is a danger that, if these costs are very high, I could lose my flat, as I have considerable debts. I would be put in a position of losing my home which would have a huge detrimental effect on my health. The judge said however that he would make sure Mr Frost got what he was 'fairly entitled to' in the way of costs and said Mr Frost's conduct in relation to the planning row and been 'blameless'. He blasted Mr Kemp for his 'disgraceful behaviour' in forging the complaint to the council. Judge Moloney said: 'The actual allegations complained of are not of great gravity - noise nuisance and clothes blowing off a washing line and annoying a neighbour. If they were any less serious, it could be said that the allegations were so trivial that they do not deserve the attention of the court. Urging the pair to make peace, he told them: 'You two gentlemen are neighbours. I'm not going to say you should have to be friends - that would be a childish thing to say. But if you could step back and cool down, and avoid coming to court again, that would be desirable, otherwise more money will be wasted.
