More of a "was I being unreasonable" as time has passed and I sometimes wonder what the right approach was.
When I was 19, my parents split up; my dad leaving my mum for another woman. Upon leaving he said my mum could keep the house. The next week he said me and my brother (then 17)could keep his share of the house. We didn't believe him to be honest and didn't expect anything
One week later when we met with him he told me that I should now pay his half of the mortgage. I told him it wasn't my responsibility (I paid my mum £250 a month rent from a £750 a month salary, so wasn't rolling in it).
My mum spoke to her solicitor who said that I had no obligation to pay my dad's share of the mortgage, and I would have no legal right to his share of the house even if I did pay his share of the mortgage each month.
When I told my dad this he shouted at me and told me that his solicitor said that it was unfair for him to pay the mortgage on the house which two grown up children lived in (at 17 and 19 we were barely grown up)
So as not to drip feed; my mum wasn't mean in charging £250 a month rent; she didn't earn a lot either.
The house was bought through right to buy and at a large discount and was due to be sold a few years later, so my dad was due to get a healthy profit from his investment.
Wibu in refusing to pay his share of mortgage? He didn't speak to me for years because of this
