Bit morbid, but I'd like to get things in order, just in case.
I don't own property and have little money, so not worried about that side of things. I want to make arrangements about who cares for my children.
I have two children:
DD - her father (my ex) is named on her birth certificate so has PR. We were never married, and even before we split up had separate residences. We split up before DD's first birthday. He sees her for a few hours at a time, 5 or 6 times per year. He has never had her overnight or for more than 6 hours at a time.
DS - his father is my current partner. We are not married but have lived together for 4 years (including before DS was born). He is named on DS's birth certificate so has PR.
If I die, then I want both my DD and my DS to live with my current partner. My partner has raised my DD since she was a toddler, considers her his daughter, and is much more capable of looking after her than my ex.
If my partner was unable to care for my children, then my mum has confirmed that she would be prepared to do this.
Is it possible to put anything legal into place to ensure my wishes?
My biggest concern is that DD would go to live with her father (my ex) if I died, purely because he has PR. I was young and foolish and didn't realise the ramifications of naming him on her birth certificate. I don't have any objection to him having contact (I don't have any reason to believe that he would intentionally harm her), but he is useless. She would not have a good life if she lived with him.
What can I do?
