I have tried my best to work this out and can't seem to work out whether I am liable or not. My solicitor reckons I will have to pay stamp duty maybe even up to 5%. But my parents bought a similar house to mine on 1/2 acre site for 317,000 and it will be owner occupier. They are selling their own house and they aren't been caught for any stamp duty. My situation is I am separated and I bought an apartment a year ago which I am now selling. My partner got his marriage annulled and we are buying the house together. The house will be owner occupier and square footage is approx 2100 and the cost of the house is 300,000 and the house is a dormer. My mother rang her solicitor this morning to make sure they hadn't made a mistake on their property and her solicitor was adamant that they don't have to pay stamp duty and I shouldn't either. My mothers solicitor rang a few other solicitors and they all agreed that we shouldn't have to pay. Both my house and my parents house are brand new houses. Can someone explain why I don't or do have to pay stamp duty and if I do how come my parents don't.
