Nodiadau Esboniadol
Testun a grëwyd gan yr adran o’r llywodraeth oedd yn gyfrifol am destun y Ddeddf i esbonio beth mae’r Ddeddf yn ceisio ei wneud ac i wneud y Ddeddf yn hygyrch i ddarllenwyr nad oes ganddynt gymhwyster cyfreithiol. Cyflwynwyd Nodiadau Esboniadol ym 1999 ac maent yn cyd-fynd â phob Deddf Gyhoeddus ac eithrio Deddfau Adfeddiannu, Cronfa Gyfunol, Cyllid a Chyfnerthiad.
