Hi. My father is thinking of selling a piece of farmland which he inherited in the mid 1970s. In order to calculate the capital gains tax, it will be necessary to get the market value of the land at the date of acquisition (1976/77). Would retrospective valuation by a local auctioneer/valuer be necessary for this purpose? Or is there somewhere else he can get this value from (eg: legal documents relating to the transfer)? Thanks.
