If my boyfriend and I get married at age 66, are we responsible for each others debts?
we each have individual debts
When you get married the pre- marital debts belong to each partner. However, any of the debts incurred during the marriage are considered joint debts regardless of the name attached to the liability.
I don't think it matters with age at all. Once you're married your debts become combined. Although, there might be something where you can keep them separate. Just not sure.
It matters what state you live in and if it is a marital property state; then it's 50/50 for debts and assets; unless you have a prenup.
