How do you prove that ex husband has hacked into my account?

Answer 1

For your bank account, if your name is on the account speak to your bank. They will provide you with a list of all transactions.

For your computer, keep track of your last login time. You can also check with your internet Service Provider to see if anyone has accessed your accounts. Finally, change all of your passwords weekly. This will insure that your ex-spouse cannot access any of your accounts.
