I think I am lucky - we open a joint account and all of his salary deposit into that account except his year-end bonus & shares. All of our expenditures are using the joint account. Now he is the only one who make money at home. Prior to my pregnancy, I save my salary to my own account when I had a job.
He let me know how much money that in his account and I also let him know about my saving figures. I think open communication is the best way between a couple.
