Don't get too complacent.
My ex got a new passport for my kid.
Said she could not locate me. (I was still living in our home. LOL)
Swore out an affidavit and got a passport.
Her boyfriend was/is a solicitor!!
Both lied on the affidavit but got away with it.
Also be mindful there are tons of female support groups. As a mere male you are suspect and assumed guilty.
And another thing. Do not be a gentleman and assume lady like action from your ex - do not trust her to keep any agreement - she will not. She will lie her teeth off and her friends will support her.
