It doesn’t matter whether property is in joint names or his sole name, any financial claim you have on it is exactly the same.
If there was a financial order as part of the divorce, you have no claim.
If there was no financial order, you potentially have a claim and you potentially have one for many years but generally, only if circumstances change.
There have been cases recently where an impoverished ex took their now millionaire spouse to court 10 years after the divorce and got a sizeable settlement.
However, each case hinges on its facts and it would obviously be grossly unfair if you were impoverished and him to be a millionaire lottery winner.
In this particular case, you agreed a settlement, albeit lower than it should have been, and he used his share of the settlement to buy a property which he has now sold.
I am a bit confused because you say he bought the property in 2013 which was after you divorced but you say it was paid for out of a joint account which doesn’t seem to make sense.
