Beetle, yes, that's right. And we know it's a fragile position. We've talked about it many times.
We are at the point actually of talking (grudgingly) about getting married. It seems perverse that we will probably do it as cheaply and unfussily as possible, with bad grace, when for a lot of people their wedding day is so important and joyful. I don't really WANT to be the miserable bugger getting married grudgingly, but the system doesn't really leave us any more choice.
reddress, I don't understand what people think the difference is between a civil partnership and marriage
For me and DP it's a lot to do with the term 'marriage' itself and its connotations of a woman being property to be given away. And also the fact that it is still the only way in which the state will, in legal and financial terms, recognise our partnership, despite us having been together happily for longer than many married couples.
Marriage and civil partnership both have another issue, though: that you need two witnesses for them to be legal. Neither DP nor I would want our wedding to be known about, which means either getting two people and a dog off the street to witness, or trying to find two friends who we could trust to keep schtum, and giving them the responsibility of never letting it slip.
He would rather just be able to write a will leaving the house to me, and not have to worry about the tax implications of that.
