A creditor can bring a claim against a guarantor of a debt in preference to enforcing its security against the principal debtor even if the creditor has adequate security.
The recent case of Mark White –v- Davenham Trust  has confirmed the basic principle that a creditor with several remedies can choose which to enforce, at what time, in which order and in what way.
The existence of security against the principal debtor should not lead to the creditor being in a worse position against the guarantor than if there was no security. It is not open for the guarantor to argue that the creditor should pursue the principal debtor or should realise the security given by the principal debtor first.
