What expenses should the couple share?
The common expenses that should be shared include rent/loan, utilities, shared meals, shared travel, and family health insurance. Personal expenses should be separated.
When should you talk about money with your partner?
Talk about money from the start of your relationship or planning your marriage. Key topics include income, debt, savings goals and money philosophy. Open conversations reduce future conflicts.
