UK - Trustees will be exposed to maladministration claims if scheme websites fail to meet legal requirements, lawyers warn.
Sacker & Partners says many schemes are still unaware of the legal pitfalls when setting up a website for scheme members.
Ball said that as more than a third of all schemes at FTSE350 firms had websites, the dangers must be better understood by schemes.
She said: “Members are not financial experts and cannot be guaranteed to use or interpret the documents in the way that may be intended.
“A scheme that fails to warn people not to rely on the website version of documents for instance, is guilty of maladministration if anything goes wrong.
“It is a new world for pension schemes and many are not adequately prepared.”
But Ball said trustees could easily protect themselves by ensuring information was laid out clearly and had carefully worded explanations with legal disclaimers.
She said the sites should also have passwords to protect information and, if they provided links to other sites, ensuring they pointed out they were not responsible for information on those links.
The Pensions and Lifetime Savings Association (PLSA) has announced it will shrink its board by more than one-third as part of a governance overhaul to make it "agile and more appropriate".
Smaller FTSE 350 defined benefit (DB) schemes were nearly 15 percentage points less well-funded than larger schemes in 2017, according to a Goldman Sachs Asset Management (GSAM) analysis.
The advent of collective pension systems could help the UK avoid demographic challenges which will make it "impossible" for society to help savers in retirement, experts say.
