In Goa, an equitable mortgage created by depositing title deeds does not typically attract stamp duty or require compulsory registration under the Transfer of Property Act. While registration isn't mandatory for this type of mortgage, banks often request it for enforceability, especially if a Memorandum of Deposit of Title Deeds (MODT) outlines specific terms. A registered mortgage deed is different and does incur stamp duty, whereas a 0.5% stamp duty may apply if registration of the MODT is insisted upon by a lender.
