More rights for people who live in mobile homes
AMs passed the Mobile Homes (Wales) Bill, on 25 September 2013, the first private member's legislation under the law-making powers granted to the assembly by the referendum in 2011.
According to Peter Black AM, who introduced the bill, this law will now give people who live in mobile home more rights.
It does not apply to holiday sites - only to sites where people have permanent homes.
It is meant to improve the way residential mobile home sites are managed and maintained, and removes the site owner's power to stop people from selling their homes.
Site owners will have to pass a fit and proper persons test as part of a new licensing regime.
They will be breaking the law - and could be fined up to £10,000 - if they do not have a licence, or allow more homes on their site than is authorised by the licence.
Councils will also be able to issue fixed penalty notices of £200 if licence conditions are breached.
Liberal Democrat AM Peter Black, who introduced the Mobile Homes Bill, said: "For too long mobile home residents have had a raw deal and not had the rights they deserve."
