Pact de non alienando

An agreement not to niienate incumbered (particularly mortgaged) property. This stipulation, sometimes found in mortgages made in Louisiana, and derived from the Spanish law, binds the mortgagor not to sell or incumbar the mortgaged premises to the prejudice of the mortgagee; it does not avoid a sale made to a third person, but enables the mortgagee to proceed directly against the mortgaged property in a proceeding against the mortgagor alone and without notice to the purchaser. See Dodds v. Lanaux, 45 La. Ann. 287, 12 South. 345.
