Secured creditors are creditors with valid mortgages or liens against property of the person filing . Property that is encumbered by a valid mortgage or lien is called secured property. A secured creditor is usually permitted to repossess or foreclose on its secured property, unless the value of the secured property greatly exceeds the amount owed to the creditor. The claim of a secured creditor is called a secured claim and secured claims are collected from or enforced against encumbered property. Secured claims are not paid by the trustee. A secured creditor must prove the validity of its mortgage or lien and must usually obtain a court order before repossessing or foreclosing on encumbered property. Encumbered property should not be turned over to a secured creditor until a court order to do so has been obtained, unless the property is encumbered only to finance its purchase. The debtor may be permitted to retain certain types of encumbered personal property (see Question 34, below).
