Can a father prevent his 17 year old daughter from seeing her older sister?
Yes, if the father has parental custody of the minor (depending on what State you live in.) He may have good reasons why he doesn't want you to see your older sister. You can wait until you are 18 to see her and no one stop you then.
I think you mean "what do you call my father's sister's daughter?" She would be your 1st cousin and your fathers niece. ___________________________________________________________ Niece by definition is the daughter of one's brother, sister, brother-in-law, or sister-in-law. While Cousin is by definition the son/daughter of your uncle or aunt. Accordingly, the daughter of the sister of your father is your cousin Refer to link below
Provided no court orders exist, yes. Unfortunately, it this involves an adult sister, she lacks standing in the court to take action. Write letters, make a copy, and mail them with delivery confirmation. Printout the confirmation from the USPS web site and attach to copy for filing. If the father intercepts the letters, you can show the copies to her when she reaches 18.
In most cases, your sister-in-law's daughter is also her husband's (your brother's) daughter and your niece. If the daughter is from a different father than the daughter is not related to you unless your brother adopts her. Then she is your niece. If the daughter came into your brother's family at a very young age and is still part of that household, he may be treating her as his daughter, even if he has not…
Why in general mothers-sisters feel that son-brother's wife will take away their son-brother but don't feel that daughter-sister's husband will take away their daughter-sister?
Answer: Because daughter-sister-father feel son-brother-mother-daughter is take away their daughter-daughter-uncle but brother-mother-father think son-mother-father-daughter go away to brother-sister-mother. Answer: This question is based on a rather doubtful assumption, unless, perhaps, it applies to some specific region or culture. As a general proposition, any answer would be purely speculation and of little value.
Your aunt is the sister of either your mother or your father. Your aunt's sister is either: your mother, and her daughter is you (if you are a girl) or one of your sisters, or another one of your mother's sisters, and her daughter is your first cousin, or, one of your father's sisters and her daughter is your first cousin.
There are three possibilities: If you are male, your sister's sister-in-law could be your wife. Then the sister-in-laws's daughter is your daughter. Your sister's sister-in-law could be the wife of your brother. Then the sister-in-law is your sister-in-law, too, and her daughter is also your brother's daughter and thus your niece. Your sister's sister-in-law could be the sister of your sister's husband. Then the sister-in-law is not related to you, and neither is her daughter.
Thius question is probably intended ot be a riddle wiht the answer being "your father" and presumes the following logic. Your mother's only sister is your aunt. Her son is your first cousin.
