Any debts in your partner’s name alone as of the date of separation will be included in his or her net family property. Ultimately, they will be responsible for paying their sole debts, but the amount will affect the equalization calculation. Balances on joint lines of credit and joint credit cards as of the date of separation are considered to be shared equally but if used by one spouse post-separation, although an accounting is required, the reality is that both spouses are fully responsible for payment of the joint credit facility to the financial institution.
