XH and I separated for 6 years. Finances sorted amicably 4 years ago. We share a teenage son. We never processed the divorce paperwork, so we're still married.
I bought a house with new partner a couple of years ago. A friend told me at the weekend that XH has a claim on my new house as we're still married. I now see this was a massive mistake on my part.
As XH and I are happy with how the finances were sorted years ago, can I just start the divorce online today? Or do I need to get some sort of financial agreement prepared that is legally signed off saying we're both happy with what we arranged?
Thanks
