Sometimes, to show belonging you can use the structure of 'of + possessive pronouns'.

'Yours' can mean 'your family and your close friends'.

I'd like to invite you and yours for dinner on Sunday .
Usually, at the end of a letter or email before they write their name, people write phrases like:

Yours

Is "Your's" Correct?
Even though one might see "your's" in written texts even by native speakers of English, "your's" is incorrect.
You should never write 'Yours' with an apostrophe.
