What could new rights for unmarried couples mean for your money? When Amelia's fiance died suddenly in his 20s, just months before their wedding, she never imagined the legal and financial turmoil that would follow. I lost him, she says, and then I lost everything we'd ever built together. The couple had been together more than seven years and shared a business. But they were not married and Simon did not have a will, so his mother and father inherited all of his assets - apart from the couple's house - and Amelia was unable to stop them.
