Transfer of Property Act, 1882 — section 79

79. Mortgage to secure uncertain amount when maximum is expressed..—If a mortgage made to secure future advances, the performance of an engagement or the balance of a running account, expresses the maximum to be secured thereby, a subsequent mortgage of the same property shall, if made with notice of the prior mortgage, be postponed to the prior mortgage in respect of all advances or debits not exceeding the maximum though made or allowed with notice of the subsequent mortgage. Illustration A mortgages Sultanpur to his bankers, B & Co., to secure the balance of his account with them to the extent of Rs. 10,000. A then mortgages Sultanpur to C, to secure Rs. 10,000, C having notice of the mortgage to B & Co., and C gives notice to B & Co. of the second mortgage. At the date of the second mortgage, the balance due to B & Co. does not exceed Rs. 5,000. B & Co., subsequently advance to A sums making the balance of the account against him exceed the sum of Rs. 10,000. B & Co. are entitled, to the extent of Rs. 10,000, to priority over C. 80. 1[* * * * * * *] Marshalling and Contribution 1 [81. Marshalling securities.— If the owner of two or more properties mortgages them to one person and then mortgages one or more of the properties to another person, the subsequent mortgagee is, in the absence of a contract to the contrary, entitled to have the prior mortgage-debt satisfied out of the property or properties not mortgaged to him, so far as the same will extend, but not so as to prejudice the rights of the prior mortgagee or of any other person who has for consideration acquired an interest in any of the properties.]
