Hey Jack, i had my visa and my son's approved just last week.
It was a rough ride to make my son's dad give him the permission but we made it through. The permission your fiancee's ex has to sign is the one available to download on the migration people webpage (http://www.migracioncolombia.gov.co/index.php/servicios-al-ciudadano/descargas)
I went to their office in Cali and ask them personally how old that permission must be to be accepted by Migracion at the airport. They said it doesnt matter how old it is as long as your fiancee and her child leaves in the exact same date as the departure date stated on it. Again, i went PERSONALLY and ask them and this is the information they gave me. ALSO and very important is that the father has to fill the document up with his own handwriting and have it notarized.
Another option is to pay for the Escritura Publica. It is a permanent permission for the child to leave the country. This one expires in 30 days, but you ask for a notarized copy and the validity certificate when you are sure you're leaving in less than a month. The Escritura Publica is really like the best option because that saves you the trouble of asking the father to give out his signature everytime you come to Colombia. Keep in mind that you can use it as long as the father doesnt revoke it, which i believe it wont be your case.
We got both of them cause i didnt wanna take the risk, but whichever is good. Which one is up to you, guys.
I wish you the best with your big family!
Anything you wanna ask me, feel free to do so
Either my fiancé or I will answer
