Decree Nisi and Absolute

So my partner has been married before in his early 30s (we are both over 45!) and a few weeks ago he gave me his “divorce papers” so I could keep them safe for when we give notice which is now this Thursday. So yesterday afternoon before he got home from work I was working and decided to check we have all the right paperwork. This one piece of paper he gave me said Decree Nisi in tiny letters at the bottom of the page. Now don’t get me wrong I’m not marriage and divorce expert but I panicked as I know you need the Decree Absolute.
Cue lots of panicked googling and me having a fit about whether he is even divorced!
As soon as he walks through door I bring it up and his face is a picture- typical man answer- I don’t know she dealt with all that. So he goes upstairs and rifles through piles of paperwork whilst I’m pacing the kitchen thinking how I’m going to tell my mum we can’t get married legally on 23rd July this year.FH eventually comes downstairs with lots of papers and a decree absolute.Talk about having a stressful two hours. I could have killed him. I think he even thought he might still be married as he didn’t get involved with any of the paperwork and I was flapping as she was only 24 so I kept thinking maybe she didn’t understand the whole process - I don’t think I do! So the morale of the tale is -keep your paperwork in order.Had to have a gin and tonic after that and had to share it as was so stressed 😩
