Yes they can share a Bedroom as long as they have different beds. Because otherwise that's just weird.
Nope if she is over 8 years old
There's no age limit. It depends on the child's personality and maturity. She might want to share a bedroom with her parents until she's 12 due to nightmares, phobias, fears, etc.
Yes, a half sister can share in her fathers estate if she was the blood daughter of the father.
None. You do not share a common ancestor. He would be introduced as your daughter-in-law's father.
no, no she can not
It is not illegal for children to share a bedroom with their parents.
Depends on if the parent is a make or female. Mom can share a room with her son until he is 3 years old, but she can share a room with her daughter until she is 5 years old. Dad can share a room with his daughter until she is 3, but can share a room with his son until he is 5.
You should write daughter's if you are talking about one daughter, e.g. "it is my daughter's birthday tomorrow".You should write daughters' if you are talking about more than one daughter at the same time, e.g. "this is our daughters' bedroom, which they share".
It depends what the father and brother is like and if you feel that you can trust them. If you have any doubts whatsoever about this then no, its not alright. But if the father and brother are trust-worthy people and aren't absolute brutes or sexual offenders then that is alright, IF THE GIRL FEELS COMFORTABLE WITH THIS IDEA.
