hi Joannet, i think since you're already married, it just how long you've been married...then you can probably insert a separate sheet of bond paper with an explanation like mine...

Ex. June 14, 2007 our relationship started
June 28, 2011 Got Engaged
Oct 4, 2012 Got married

Thats how i do it, and the question "Do you intend to work in the UK...

I asnwered YES as soon as Im allowed to work. ( I don't know if it applies to you as I was applying for fiancee before) Hopefully this will help you
