And, OT, a parent can't even get a passport for a child under fourteen without the other parents signature, even if divorced.
Not true. I got passports for my minor children this summer without their father's signature. We are divorced, and I have full/sole custody as well as care and control tho. I'm nice and informed him I was doing it tho. All they asked for was the divorce papers (presume they were looking for custody arrangements) and birth certificates. I could probably have done it before the divorce was final based on the requirements they asked for. The separation agreement stated I had custody and care and control.
My mother moved us from the Southwest USA to Eastern Ontario when I was 6. She had my father sign saying she had his permission to take me out of the state as well as out of the country. She remarried and he was in Ontario, so we moved to be with him.
I left the province with my children when my ex asked for the divorce, before there was a formal legal agreement... I think I had him sign a letter and have it notarized.
