Steps

  1. List the costs you share, such as rent, utilities and groceries, and total them monthly.
  2. Decide how to split them: equal amounts, or in proportion to each person's income.
  3. Choose a structure: all joint, all separate, or a joint bills account plus personal accounts.
  4. If you open a joint account, set both people to receive alerts for large withdrawals.
  5. Keep a personal account in your own name with your own savings, even if it is small.
  6. Review the split whenever either income changes a lot.
