Can one of them bankrupt the marital home mortgage but the other one not do so & keep the house?
Many things are possible in this world. Yes, one person can discharge a debt in bankruptcy and the other (non bankrupt) person on the debt will still be repsonsible.
If you going through a divorce, the most practical thing is to either file bankruptcy together before the divorce is completed, or file bankruptcy alone after the divorce is completed.
If one person wishes to keep the home and the other does not, the person keeping the home must continue to make the payments.
Hope this perspective helps.
Divorce / Separation Lawyer
I agree with the opinions of both lawyers, but I would say that if the two of you are amicable I would attempt an uncontested divorce and see if you can agree to one or the other of you having the house. I would then file for bankruptcy and pull the house through that and then at the reaffirmation of that debt, see if you can modifiy the mortgage into the name of the spouse wanting the house.
The divorce agreement, decree or judgment supposedly settled the rights and obligations between you and the former spouse. However, it does not change the obligations each of you had with third parties who were not in Court when you got the divorce.
The ex-spouse may refuse to make payments to credit card companies, car financing companies, mortgage companies, etc. Your ex may even file for Bankruptcy.
Depending on the law in your State you may have an action against the ex-spouse, and you may even be able to sue the ex-spouse if they file for Bankruptcy and have their obligation to you declared “non-dischargeable”.
Unfortunately the divorce or the ex’s Bankruptcy does not relieve you of any obligations you had to these third parties.
