That’s according to a recent ruling which ruled you are only entitled to a share of your spouses jackpot if he invests it in a shared asset such as the family home. If they choose to simply bank the winnings, however, then the other partner can leave the relationship without having to give away half of the money. The ruling was made in the case of a hotel porter who sued his former wife for a share of her £500,000 National Lottery winnings. The couple had been living in a council house when the woman brought the lottery ticket without her husbands knowledge. She used some of the money to buy a house in London costing £275,000 where they lived with their children for two years. When the couple separated the husband believed he was entitled to his share of the house, now worth £500,000. A judge ruled, however, that the husband was not entitled to anything like an equal share of the house as he had only lived there a short amount of time and awarded him £85,000. He also said that had the couple operated a syndicate in which both were aware the tickets had been brought then the money would have been shared equally. It’s an interesting ruling and I guess something you should consider if you believe you will become separated from your partner. Personally I would be more than happy to share any lottery win with my husband.
