A total of one in ten adult children think their retired parents are spending too much of what they feel should be their inheritance.
One in five adult children - 19 per cent - are relying on inheritance from their parents, up 17 per cent on last year, according to SunLife's survey of 2,984 online interviews among adults between 18 and 70, undertaken by Charterhouse Research.
However, the research also showed that 17 per cent of 55-65s expect to be supported financially by their grown up children when they retire.
According to SunLife this has created a "tug of war" which is now affecting many peoples lives.
A fifth of 18-34 year olds are providing financial support to their parents while one in seven 55-65 year olds are providing financial support to grown up children no longer in education.
A large number of the 18-34 year olds are finding this support a struggle at 80 per cent, with half of them saying it is a constant struggle
In contrast, 63 per cent of 55-65 year olds who support adult children find it a struggle, with only one in seven saying it is a constant struggle.
Ian Atkinson, head of brand at SunLife said: “We’re seeing an older generation with high home ownership spending their savings, investments and income on enjoying the best years of their life, knowing they can still leave their home as a legacy.
"It’s not really fair to call them 'skiers' - spending kid’s inheritance - it’s their money in the first place, and perhaps it’s only right that, when they’re reaching an age of more free time and fewer responsibilities, they’re using that money to fulfil some lifelong ambitions.”
