As you divorced her, the family law no longer applies to this situation. You are joint owners of a property and on first examination you are each entitled to a half share of the proceeds of sale. Your only remedy against this general rule would be the doctrine of unjust enrichment, that is to say, it would be inequitable for her to profit from your contributions to the property over the years. However unjust enrichment is subject to a five year prescriptive period. That means no claim for unjust enrichment could be made after the point at which it could be said that there was no intention that she benefit from the property. That date is likely to be your separation date, so you should have dealt with this issue at or about that time. I'm afraid that time having passed you may have a difficulty with this given that more than five years have passed and the property remains in joint title. I hope that helps. Please leave a positive rating so that I am credited for my time.
