Why would they use a word like "kids" (rather than "children") in an official filing?
Does not sound quite legit to me.
To say the least, an unusual way of putting it, jarringly so in a legal document.
Additionally, the name Cindy is usually a nickname for the more typical given name Cynthia. Unless the name Cindy, not Cynthia, is on her marriage certificate, this also looks odd.
The website appears legit. I went to the Solano County Superior Court website and clicked on the link used to search for court cases filed. A clerk may have used "kids" for any number of reasons.
