The Aged Care Association Australia (ACAA) has called for tighter rules on retirement villages as hundreds of elderly residents face eviction across the country.

The Village Life company has sold 10 of its villages to property investment group MFS and the two are now involved in a dispute over tenancy arrangements

As a result, more than 400 residents face eviction.

ACAA chief executive officer Rod Young says there needs to be a national approach to the laws governing retirement villages.

"At the moment the issue of security of tenure is quite different between Commonwealth-funded nursing homes and retirement villages and in fact there are considerable differences between the rules regulating this between states when you're talking about retirement villages," he said.

He says long term security of living arrangements for the elderly cannot be guaranteed in every situation.

"I guess it's the rules regarding how that gets handled, the period of time that should be given if people do have to be relocated from existing services and the sort of support that should be given to particularly old and frail persons finding new accommodation."
