karma that's true. It could all go pear-shaped for me as it could for OP.
curryeater my DP and I just bought a flat together. We own it jointly; this means that both of us own the entire flat. In practice, this means if either one of us died, the other one would automatically be the owner of the entire property - it's not a question of 'inheriting' the other's 'half', as each of you already owns the whole property, so there's no tax issue. (genuinely) HTH
It was easier in our case as we each contributed 50% towards purchase price, but even if you contribute different amounts you can draw up a separate deed which lays that out.
Also speaking as a feminist, I understand what you're saying but equally, just because some women want a thing, that doesn't automatically make it worthwhile and serious and important, any more than it makes it stupid, trivial and foolish.
I take financial security, love, commitment and having children very seriously; however, I don't feel obliged to respect the desire to dress up as a princess for a day any more seriously than I did when we were seven (and it was always the girl with the longest, blondest hair...)
