Questions regarding divorce in Ecuador

Hello all!

I have a question regarding the divorce of my boyfriend and his ex-wife. He is Belgian and she originally is from Ecuador, but moved to Belgium after the marriage (that's the reason for the marriage). A few years ago they got a divorce here in Belgium, they got married over 10 years ago in Ecuador, but the ex now contacted my boyfriend since they are apparently still "married" there, even though they divorced here( Belgium). She claims she needs to pay 7.600 dollars to take care of everything. My boyfriend has 0 business etc with her, so he wonders why he has to pay for it (she asked) and why she even has to pay anything. How can he take care of the divorce in Ecuador, so he doesn't have any problems etc in the future? He has e-mailed the Ecuadorian embassy here in Belgium, but they haven't answered yet. She is kinda pressuring him into answering her request for the payment. We tried to do some research and were thinking if it's just not enough to translate the Belgian divorce papers in Spanish and send the to the embassy? We're kinda lost right now.

I'd really appreciate your help here if there's anyone who know something about this. Thank you in advance!
