The LDoC itself sets out what is required. Common examples include: a utility bill or council tax bill in your name at the property dated 14 February 2022 (to confirm it was your main home); a copy of the HM Land Registry title showing current ownership and the last sale date; a copy of your sale contract or completion statement confirming the price you paid; and if you are a shared ownership leaseholder, a copy of your shared ownership lease and associated documentation confirming your percentage share at 14 February 2022.
