leaving apartment in Poland to bank

If I get into a sitaution where I leave my apartment to bank because I can not pay the high mortgage rate now since the change of currency value. Does my extended family get in trouble to the bank? I am told that my brothers and sisters would be responsible?

Did your brother or sister sign the documents? As you have accounting as your job, you should know that it is only the people that are listed on the documents that can be held to pay.

There is no such thing as leaving apartment to the bank in Poland. Your apartment can be seized and sold if you can't repay it, but it don't end your debt if auction price didn't match your debt. If you just leave it, and stop paying you most probably will end up with enourmous debt due to interests in couple of years from now...

The people responsible for your debt can be those in mortgage documents (if you had guarantors). Besides that, probably your wife (if you don't have marriage settlement).

Anyway, you should check out with a lawyer....

First thing.
where is your flat? Size?
If your wanting to leave it to the bank.
I will take over your flat and pay the mortgage, as you are going to just leave it anyway.

PM me if you're going to think of this way.

If you just leave it to the bank you will prob spend about 200% more in costs and fines.

right that is true, same in UK, my bro had a flat repoed in the 80s, I think he just walked away, well he got a huge bill years later.

Better you think of other options.
