Capital gains tax

nisadave

I gave my parents the money to buy their council house in 2003 and they placed it in trust to me.On the trust deed it refers to myself as the purchaser.My mother died last year and my father has now moved into residential care.My father can now sign the house over to me.If he does am i liable for capital gains tax also if the house is left in his name would i actually inherit the house after his death and therefore avoid CGT.also what would happen if i sold my own home (no cgt payable) and moved into his empty home and sold it after his death.Would this attract cgt as it would now be my main home ?
