I am married under the community property regime. My husband acted as guarantor for a friend. That friend has now defaulted, and my husband is being called upon to honour the guarantee. Can the creditor seize my income?

No. The law provides that when one spouse acts as guarantor without the express consent of the other, only their personal assets and income are liable. Therefore, if you did not sign the guarantee agreement, your earnings and salary cannot be seized (Article 1415 of the French Civil Code).
