An Agricultural Clause within a Will in the UK is a provision that is included when the testator (the person making the Will) owns agricultural assets that are expected to qualify for Agricultural Property Relief (APR) from HMRC. The Clause is used to direct these assets to an appropriate number of Family Agricultural Trusts, which are considered Pilot Trusts.

This approach is recommended to ensure that the assets are passed down to future generations and to maximize the potential tax benefits for the estate. It also helps to ensure that the assets are properly managed and utilized. The use of an Agricultural Clause can be particularly beneficial for those with larger estates or agricultural holdings, as it can help to minimize the tax liability and protect the assets for future generations.
