One important thing to remember is that, according to the Czech Civil Code, debts acquired during the marriage are also joint property. For example, if you bought an expensive car with a loan paid from your own income during the marriage, the car is automatically considered common property, even if only your name is on the title. This will be the case for the loan as well, except if you go through a court proceeding to contest the debt, claiming that you were not aware of it and did not agree to it.
