It was a requirement that an affidavit be sworn in front of a justice of the peace (usually by a relative of the deceased), confirming burial in wool, with the punishment of a £5 fee for noncompliance. Burial entries in parish registers were marked with the word "affidavit" or its equivalent to confirm that affidavit had been sworn; it would be marked "naked" for those too poor to afford the woollen shroud.
An Act to repeal Two Acts of the Thirtieth and Thirty second Years of King Charles the Second, for burying in Woollen, and for indemnifying Persons against Penalties for Offences committed against the said Acts.
The legislation was in force until the passing of the Burying in Woollen Act 1814 (54 Geo. 3. c. 108), but was generally ignored after 1770.[6] The 1666 act had been annulled by the passing of the 1688 act; it was repealed by the Statute Law Revision Act 1863 (26 & 27 Vict. c. 125).[7]
