I’ve signed the legal papers for my ex-wife to legally include her surname as well, so the surname of our children would be double barrelled. However, I have just found out (by getting a christmas card from my kids that they made in school) that my surname is no longer theirs and only my ex-wifes surname. Having had a long (and heated!) discussion about this with my ex, I have found out that my surname is now included as a middle name for them. This is not what I signed, and apparently the only reason this has happened is because a dash wasn’t added in between the two names.
