When I divorced and had to sell our large house to downsize (and move 150 miles away !) and bought another house I always told my daughter that it might /might/ be hers one day when I died. That is, at that time I said unless the house has to be sold to pay for my care when I am ancient. She always told me when she was young (as in teenager) that she wasn't going to look after me (!) ....we used to laugh about it ! However circumstances change and I remarried and moved to firstly Spain, and then France. In both countries the law is different as regards inheritance, in that children inherit automatically ...slightly complicated where step children are involved. We have Wills that leave the house to the surviving partner and then to the children ....but if I die first only his daughter inherits, and vice versa, she has told us she does not want to inherit in which case she has to give her decision in writing to a Notaire. My daughter has not spoken to me for ten years ,,,,she came to see us in our first house in France, a large old house we renovated ..and promptly declared 'I have come to see my inheritance' (!) ....we moved to a much much smaller bungalow ..luckily, as we both had health problems ,,my husband is now 84 and diagnosed with Parkinsons disease which makes even staying here difficult but he will not consider an apartment ! When my daughter came to see this house just over the 10 years ago, she was very disappointed and declared it was nothing more than a bed sit (it is a 3 bed detached bungalow with a large (by UK standards !) garden a conservatory, etc etc but not worth as much as the big one, and now not worth even what we paid for the land to have it built on due to the property slump here ....so, having decided we have no money to leave or to spend on her anymore (I used to send her money, pay for things, holidays, etc etc )
she evidently decided that she did not want anything more to do with us !
My dead DAd on the other hand, sold the family home after my mum died, rented a retirement flat, and said to my brother and I ' I will put the money into a bond at the Bank and you have half each; ...we told him we both owned our own homes, and that he was to spend the money and be happy and enjoy it ! bless him ...so he did ...he had lovely holidays, new furniture for his flat, etc etc and we were pleased for him ....and also at the end of the day when everything was paid we both even had a small inheritance ,which was unexpected and really good as I was by then a single parent and managed to pay for driving lessons for my daughter, buy a small car for her and even have a holiday I Turkey ,,,and pay off some small debts ! My brother chose to go to Myanmar, India and Cuba in pursuit of his passion for ancient steam trains .....and we remember our dad with gratitude and thanks and the pleasure of knowing he spent his money and had a good time bless him !
I think it is ungrateful of children to expect anything ..like op's have asked, why do children have this expectation of an inheritance nowadays ? maybe its the Thatcher era of 'money cascading down the generations' or just a general feeling of entitlement ? sad !
