Putting new partner on mortgage but still married

If someone is still married but getting divorced does having the new partner take over the stbexh's half of the mortgage affect the divorce in any way? New partner is on the mortgage now but divorce not finalised.

How did it go, OP?

Well that’s a real live shit show in progress 🫣

My XH and I split amicably, he stayed in our house and I bought a new one. We wanted to crack on with that well before the Consent Order would ever have caught up with our preferred speed! He remortgaged to his sole name, and on the same day (the conveyancing solicitor managed the timings) his bank sent a message saying I was released, with triggered my bank to complete my new sole mortgage - and that was it done.

But… we already had the Consent Order drafted and agreed between us, and my solicitor produced a letter for us both to sign to say that our intentions were to ignore my new house as an asset and complete financial settlement based on the old house and all details in the draft CO. That wasn’t legally binding, but she said it would be hard for either of us to justify a change of mind. I also had to sign to say it wasn’t legally binding and I was acting against her advice not to get CO before buying new property.

In my case though, I wasn’t then tying myself up financially with someone I’d been with 5 minutes 🤷🏻‍♀️

I'd completely forgotten to update the thread.
It didn't go well. Her divorce is now final and the mortgage was sorted with the new guy a few weeks ago.
His kids are a handful with one late teens and off the rails, not working or in education. One has significant additional needs. One he barely sees. The older two have expressed a lot of unhappiness about their dad's move but she thinks they just need to accept it. Her own kids aren't keen on her new guy. He hasn't actually officially moved in yet but is there most of the time. The house is being renovated and is barely liveable atm.
What a shit show. She won't listen to anything I say no matter how gently I say it.
