Am I related to my brother in law's wife?

Question

Some say she's my sister in law but my friends say she's not related to me. 

Answer 1

It appears your brother-in-law's wife is your sister, therefore, you ARE related to her.

Answer 2

Only by marriage, but not by blood.

Answer 3

My 2 brothers in law's wives are my SISTERS!

Am I missing something here?

Or are you?

Answer 4

i would ask her this question

Answer 5

She's not genetically related, but related by marriage and part of you extended family.  I swear, people these days !

Answer 6

Any time the addenda "in-law" is affixed to a title it means the relationship is by marriage (or by "law"). So you're related by marriage but aren't blood kin. 

Answer 7

She is a relative, but not a blood relative.

Answer 8

She is most certainly part of your extended family.

Think of it this way: If you were to have an event... be it a birthday party, Christmas lunch, whatever, you would most certainly add her to the guest list as she is family. 

Answer 9

Yes, that would be your sister-in-law, or the generic in-law.  (Or your sister.  A brother-in-law is your sister's husband too).

Answer 10

Unless you have been adopted and don't know who your family is then I really don't know what to tell you. How do they know this? As long as you did not do it on purpose
