Is this sentence punctuated properly - your mother's and father's marriage was unique?

Answer 1

Almost; but you should remove the apostrophe and the "S" after the word "Mother".

The end sentence will be; "My mother and father's marriage was unique."

Answer 2

Yes, the sentence is punctuated properly. The possessive form for both "mother" and "father" is indicated by the placement of the apostrophe before the s, making it clear that it refers to the marriage belonging to both parents.

Answer 3

It should be--- Your mother and father's marriage was u

nique.
