What do you mean by signatories to sign jointly and severally?

When signatories agree to sign jointly and severally, it means that each signer is individually responsible for the entire obligation, as well as collectively with the other signers. This arrangement allows a creditor to pursue any one of the signatories for the full amount owed, regardless of the agreement among the signatories. It provides greater security for the creditor, as they can recover the debt from any one party without needing to involve the others.
