each person pays their own share; individual responsibility for costs
Used in contexts such as group meals, shared expenses, or event costs where each participant covers their own portion rather than splitting equally or having one person pay. The legal term 'joint and several liability' is a technical equivalent, but in everyday Japanese it simply means 'pay for yourself'.

Transportation costs will be borne by each individual.
