Deddf 2016 yw'r newid mwyaf a wnaed i gyfraith tai yng Nghymru ers degawdau. Mae'n cynyddu'r amddiffyniadau i denantiaid a thrwyddedeion, a elwir yn 'ddeiliaid contract' yn y ddeddfwriaeth, mewn nifer o ffyrdd. Mae'n cyflwyno gofyniad i roi chwe mis o rybudd i landlord derfynu contract os nad yw deiliad y contract ar fai. Yn ogystal, gan na fydd landlordiaid yn gallu cyhoeddi hysbysiad i hawlio meddiant yn ystod y chwe mis cyntaf o feddiannaeth, bydd gan ddeiliaid contract sicrwydd deiliadaeth am o leiaf blwyddyn o’r dyddiad meddiannu. Golyga hynny y bydd gan ddeiliaid contract yng Nghymru yr amddiffyniad gorau o ddechrau eu contract nag mewn unrhyw ran arall o'r DU.
The 2016 Act represents the biggest change to housing law in Wales for decades. It increases protections for tenants and licensees, who are termed ‘contract-holders’ in the legislation, in a number of ways. It introduces a six-month notice requirement for a landlord to end a contract where the contract-holder is not at fault. In addition, as landlords will not be able to issue such a possession notice during the first six months of occupation, contract-holders will have a minimum security of tenure of one year from the date of moving in. This means that contract-holders in Wales will have the greatest protection from the start of their contract than in any other part of the UK.
