H and I have been together 15 years, married for 10 and I am very close to asking for a divorce. After getting together but before getting married, I inherited ~£300k, some went on our mortgage as an over payment but I still have 75% of it. What's the likelihood of this being considered a marital asset on divorce? I think the rest of our finances are pretty straightforward but wouldn't want him having "my" money. Thanks for any advice!
