The new law will not apply to holiday sites - only to sites where people have permanent homes.
"Under the current law there is little protection for residents from unscrupulous park homes site owners, a minority of whom may exploit their position for personal gain," Mr Black said, "Many of Wales's 96 park homes sites are run well but there is little legal help when disputes arise.
"Problems can include poor site management and vetoing or deterring legitimate sales.
"My bill will stop this unfairness. Wales will have a new system that will protect people by bringing in fair, easy-to-use processes and clear rights for both residents and site owners."
'Fit and proper'Mr Black said there would be a "fit and proper" persons test for site owners, and a licensing system to give home owners confidence that the site they live on is effectively managed.
