Hi I am a widow of a Frenchman. We were married with a contract of community.and I moved into his house.He has 3 children whom I have never seen as they were estranged from him on their choice about 20 years ago.I found one son on fb to inform him of his fathers death and he was not interested.I don’t know if this son is in contact with the other 2 or not.When I was sorting things with the notaire he told me if I wait 10 years the property becomes mine and the children cannot come forward for a share of it.It has been 3 years now since my husband died and I would like to sell the house and move back to the UK ,So in theory I have 7 years to wait till it becomes mine ,but I am worried that if I try to find the children now I will only end up with a quarter of the value.We did a lot of renovation together and I have also done quite a lot since. Does anyone have any thoughts please?
