Married 9 years, together 17. We put our money into a joint account checking before we got married, shortly after living together for the first time. We started with I paid the bills and then he gave me half but that got annoying so we put our money into one account. We both work FT and are both reasonable spenders so we have no issues with a joint account. Most of our bills now are on auto pay, I pay my CC and he pays his out of our 1 main account.
