This situation should not be underestimated, it may be that there is not enough communication in the early stage, or it may be that the husband is hiding. In any case, as the affected party, you still have the right to participate in solving the problem.

First of all, you should confirm the real situation of this debt and the proportion you should bear, and leave evidence to prove it. If the husband bears it alone, he can help to reduce the foreign debt. If both parties share the burden, the burden ratio can be negotiated. At the same time, you can also agree with Party B on the debt settlement period to ensure that both parties fulfill their debt obligations.

Anyway, in a sense, this matter is also a test in marriage. You should communicate with your husband and find a solution that is satisfactory to both sides.
