From Wikipedia:

In May 2008, it was announced that a 1977 will, found soon after Larsson's death, declared his wish to leave his assets to the Umeå branch of the Communist Workers League (now the Socialist Party). As the will was unwitnessed, it was not valid under Swedish law, with the result that all of Larsson's estate, including future royalties from book sales, went to his father and brother. His long term lover Eva Gabrielsson, who found the will, has no legal right to the inheritance, sparking controversy between her and his father and brother. Reportedly, the two never married because, under Swedish law, couples entering into marriage are required to make their addresses (at the time) publicly available; marrying would have been a security risk. Owing to his reporting on extremist groups and the death threats he had received, the couple had sought and been granted masking of their addresses, personal data and identity numbers from public records, to make it harder for others to trace them; this kind of "identity cover" was integral to his work as a journalist and would have been difficult to bypass if the two had married or become registered partners.
