A legal separation is only a temporary solution and the action is filed with the intention of eventually following though with a divorce.
A legal separation is not an appropriate way to protect a spouse's assets when the parties are separated and the other spouse continues to accumulate debt. If the parties are separated and there is no hope of reconciliation, the debts acquired by each spouse are that spouse's separate obligation. If the spouses are attempting to reconcile and the parties are concerned with protecting their property rights, they should enter into a written agreement which makes it clear that any debts either party accumulates is the sole and separate obligation of the party who acquired them.
