Bank Checking Accounts with Joint Holders

[doncoulter]

I don't know anything about Cuentas Solidaria or Indistinta, nor about Banregio, but I can tell you that my wife and I have what amounts to a joint checking account, with debit cards, at Santander. To be precise, the account is in my name, and my wife is "co-titular." Santander told us that we each have, as you say, "full rights to administer the account, without the approval or presence of the other." The only exception is that my wife can't close the account, though presumably that would change upon my death, as she is my sole heir.

I'll add that my experience with Santander, together with what I hear from others about their banks here, leads me to believe that all Mexican banks suck.

Hope this is helpful.
