The short answer is that unless your proposed purchase forms part of your divorce settlement, I can’t see how your ex-wife would have any entitlement to a share of the equity. You should take care of what you would like done with the property in the event that something should happen to you within your will, and this is something that should be upadated in light of your impending divorce.
When looking at the new mortgage for yourself, the lender will assess your outgoings in relation to any maintenance that you are paying to your ex-wife, and they will also take into account for affordability whether you are still on the joint mortgage.
