l seperated from my ex partner 18 years ago. We have a joint mortgage which he continued paying for around 2 years but paid no maintenance. He then stopped paying mortgage and paid maintenance, which he worked out after deductions. l now have 5 further children all under 16. My ex now wants to force the sale of my home and take 50% of the profit. l don't want to sell. Do my younger children stop the forced sale eventhough they are not his. He also has a charging order against the house of over £17000 from 19 years ago and wants me to pay half eventhough it's solely in his name.
