I have opened a bank account shortly after getting married, solely in my name, and we never mixed our funds. I funded it initially with money I earned prior to marriage. My husband did the same with his separate bank accounts. My paycheck was partially deposited into the individual account. But, we funded another, joint bank account for common expenses, bills, kids’ daycares, etc. Is my separate bank account still considered “communal”? What would need to be done to perform tracing and prove that it is partially mine?
