What's the proper form of "As a judge of your parents actions"?

Question

A grammar checker is saying I have two options, but which one is proper since you have two parents:

parents'
parent's

Note: this is for a Theology Masters paper that I hope to eventually publish into a book.

Mary · Accepted Answer

Parents' is the plural.  Parent's is the singular.

samairah nagpal · Answer

The first one (parents') is correct.
Parent's shows that something belongs to one parent.
Parents' shows that something belongs to both parents.
