Neither my Parents nor In Laws were in a position to help us financially. In fact we had to bail both sets out on occasion. However, we were able, by both working two jobs, to pay deposits on flats for our daughters when they went to Uni. They always had rent paying, bill sharing flatmates, which ensured that they could pay their mortgages and eventually sell the flats at a big profit and buy their own 'forever family homes'. Being building trade their father was able to upgrade their flats and houses and as I had just retired when the DGC came along, I was able to do lots of childminding to enable the DDs to continue working. Meanwhile we lived fairly frugally and managed to save to fund our retirement.
With hindsight, we should have transferred more of our savings to the DDs and Grandchildren a while ago, because our savings and small private pension (mostly in DHs name) ensure that DH is self funding in his Care Home £700+ per week, which means that our savings pot will have been exhausted in 18 months. If we transferred money to our family now it would be regarded as deprivation of assets and they would be required to pay it back to fund their father's care.
Something to consider when planning for retirement. Better to help your family when they need it and share their joy, than have them wait for an inheritance, which may have dwindled to nothing to meet care costs.
