After filing a claim with AESA Iberia has finally agreed to pay me 600 euros in compensation. They are asking me to provide a certificate of bank ownership. From researching I'm not sure certificates like that are a thing in the US. All the search results talk about Spanish banks. Anyone know what I need to provide? Can I get away with just the details for my bank account like routing number, account number, etcetera? I'm tempted to try that.

Second question, am I going to have to send this information in Spanish? The email they sent me was entirely in Spanish. I had to use Google Translate to discover what it said.
