The Tithe Commutation Act, 1836 (6&7 Will.IV, c.71) allowed payment of tithes in kind to be substituted by money payments. In most cases the principal records of the commutation of tithes in a parish under the Tithe Act 1836 is the Tithe Apportionment, altered apportionment and the tithe maps.

The Tithe Act, 1936 (26 Geo. V and 1 Edw. VIII. C.43) abolished all tithe rent charges. Responsibility for tithe documents created under the tithe acts (1836, 1837, 1839, 1860, 1891) were placed under the charge of the Master of the Rolls, who has the authority to transfer them to an approved place of deposit. This responsibility is exercised by The National Archives: Historical Manuscripts Commission. The Master of the Rolls has issued rules [Tithe (Copies of Instruments of apportionment) Rules 1960 (SI 1960/2440), as amended by the Tithe (Copes of Instruments of Apportionment) (Amendment) Rules 1963 (SI 1963/977)] concerning the care, custody, access to, and definition of tithe documents.

The tithe acts provided for the making of an original and two copies of every confirmed instrument of apportionment. The originals are now in The National Archives. The two copies were deposited with the registrar of the diocese and with the incumbents of and churchwardens of the parish. In many cases the copies and subsequent altered apportionments are now deposited in the relevant local record office.
