Legal analysis: You don't need your spouse's consent to vouch for others. Legally speaking, it is not necessary for husband and wife to sign a guarantee for the creditor's rights and debts of others. That is, it is also feasible that only one party signs as a guarantor and his spouse does not sign. If the spouse doesn't agree or doesn't know, then this kind of guarantee belongs to the husband and wife's personal debt when it needs to bear the repayment responsibility in the future, and can't be repaid with the same property of the husband and wife.

Legal basis: Civil Code of People's Republic of China (PRC).

Article 681 A suretyship contract is a contract in which the surety and the creditor agree that the surety will perform the debt or assume the liability when the debtor fails to perform the due debt or the circumstances agreed by the parties occur.

Article 1064 The debts incurred by both husband and wife for the same signature or by one party afterwards, and the debts incurred by one party in his own name for the daily needs of the family during the marriage relationship, belong to the same debt of husband and wife. Debts incurred by one spouse in his own name during the marriage relationship that exceed the needs of family daily life are not joint debts of husband and wife; However, the creditor can prove that the debt is used for the husband and wife's life, production and operation, or based on the same meaning of both husband and wife.
