Do i file FBAR separately for my wife, if the total balance of all her overseas accounts never exceeded 10,000$? We are filing joint taxes. I have to file FBAR myself.

Me and my wife DO NOT own any joint accounts. I have 4 accounts overseas and I have to file FBAR.

My wife has 1 account overseas and the balance never exceeded 10,000$

We are filing taxes jointly. I have included interest earned by her account as well as mine as taxable income. I need to know if she needs to file an FBAR?

If not, do i need to show the 1 account she has on her name (on which i have no authority of any kind) on my FBAR?

THanks!
