co-signs
Backs another's loan
Co-signs means to sign a document jointly with another person, typically taking shared responsibility for a loan or legal agreement: Her father co-signed the lease.
If a borrower defaults, the co-signer becomes liable.
Figuratively, to co-sign is to endorse or vouch for something: I co-sign that opinion completely.
