We understand that they can't afford to buy it.
No they don't. They said they were keen to have the place valued so they would have an idea of what money they would have available to spend on another place.
Is the issuing party able to buy the receiving party's half of the property, rather than put the property on the open market?
We have not asked them yet. If they state that they don;t wish to purchase, we are unsure whether we are allowed to have the right to purchase before the property is put on the market.
Thank you very much indeed for your guidance and information. I'm sure that it will be very helpful to us in the coming months.
