A London law firm has come up with a 'must have' Christmas present for unhappy couples - divorce gift vouchers.Lloyd Platt & Co claims to have had hundreds of enquiries since putting the vouchers, which offer couples half-hour or hour-long advice sessions with a lawyer, on sale.They cost from £125 plus VAT and the firm says it has already sold 54 in three weeks, reports the Daily Telegraph.Senior partner Vanessa Lloyd Platt said: "Christmas can be a very stressful time for families as we have always seen by the huge increase of people seeking advice in January."The vouchers seem to appeal to an enormously wide spread spectrum of people looking for that 'must have' gift for Christmas."She said that purchasers had included husbands, wives, mistresses, and people using them to suggest to friends and family members that they should get a divorce.However, the scheme has been criticised for encouraging couples to split rather than resolve their differences.Dave Percival, who organises the annual National Marriage Week, said: "It's typical ambulance chasing by lawyers who are doing this for business reasons."Anyone looking to buy this would be much better off paying for couples to get counselling."Source: Ananova
