A specific legacy (ie a gift of particular property) will fail if testator no longer owns that at their death. gift is said to be adeemed.
NOTE if property is capable of increase/ decrease, testator will normally be taken to have made a gift of any itsems satisfying the description at death.
NOTE EFFECT OF CODICIL: codicil is a supplement to a will which, to be valid, must be executed in same way as a will. it republishes will as at date of codicil. so, if a testator makes a will in 1990 leaving 'my gold watch' to a legatee, loses the watch in 2000 and replaces it, the gift of the watch in will is adeemed. if, however, the testator executes a codicil to the will in 2003, the will is read as if it had been executed in 2003 and so legatee will take the replacement watch.
