Thank you for clairfying that for me.
As it was your wifes divorce petition, if she completed the prayer at the back of the divorce petition to state her intention to seek a financial claim in relation to the matrimonial finances then despite the fact that she has remarried she can still make a claim in relation to the matrimonial finances which includes the house.
Even if she didnt complete the prayer at the back of the divorce petition as she is a joint owner of the property she could still make a claim to court under the Trust of Land Act for an order for sale of the property so that her share can be realised.
I appreciate that this isnt really what you want to hear but I do have to be honest with you in relation to the legal position.
What you need to know is that if your wife makes either application, given that your children are no longer minors and are not residing at home then it is highly likley that a court will order that the house be sold so that the equity can be realised.
You need to consider family mediation. This is a way of trying to reach agreement without the need for court. There are lots of family mediation services and there will be one local to you. Google family medaition in your area and give them a call to self refer. You may be able to reach agreement as to a payment schedule at mediation.
If agreement can be reached then you should have this prepared as a consent order and submitted to court for approval. This will prevent any future claims in relation to the matrimonial finances and you will both know where you stand.
Please do let me know if I can assist you further
