The Tithe Act 1836 (6 & 7 Will. 4. c. 71), sometimes called the Tithe Commutation Act 1836, is an act of the Parliament of the United Kingdom. It is one of the Tithe Acts 1836 to 1891. It replaced the ancient system of payment of tithes in kind with monetary payments. It is especially noted for the tithe maps which were needed for the valuation process required by the act. British Parliamentary Paper 1837 XLI 405 was published to give guidance on how landscape features were to be indicated on the maps. It is entitled ′Conventional signs to be used in the plans made under the Act for the Commutation of Tithes in England and Wales′
