Quick answer
Coordinate both cases before dividing assets, assigning debts, or filing.
Do now
Give each lawyer the other case’s orders, property list, support terms, and timing. Identify joint debts, secured property, and proposed settlement obligations. Ask how the stay and discharge exceptions affect particular proceedings.
Watch for
A debt assigned to a former spouse may still be collectible by the creditor from a signer. Support and other divorce-related obligations can receive special bankruptcy treatment.
