Specific Gifts and the Residue
Most will disputes are not about bad intentions. They are about wording that did not anticipate change. (Avoiding the predictable mistakes.)
A will gives away your estate in two kinds of gift, and confusing them causes most drafting errors.
A specific gift leaves a named asset to a named person — "my watch to my son", "S$20,000 to my niece". The residue is everything left after the specific gifts, debts and expenses are settled — usually the bulk of the estate. A well-drafted will always disposes of the residue, because that is where most of the value sits.
Three mistakes recur. The forgotten residue: a will lists several specific gifts but never says who gets the rest. Whatever is left then passes under the intestacy rules, as if you had no will for that portion — rarely what you intended. The vanished asset: you leave "my shares in Company X", then sell them years later; the gift simply fails, and the named person may receive nothing. Percentages that do not total 100: dividing the residue into shares that add up to more or less than the whole creates confusion and dispute.
The cure is structure. Make your specific gifts, then leave the residue in clear proportions that sum to the whole — and add a backup in case a beneficiary dies before you (a "gift over"). Review the will when you buy or sell a major asset, so the gifts still match what you own.
This is exactly the kind of detail where a professional drafter earns their fee. A clear residue clause is cheap insurance against an expensive dispute.

The chart breaks a sample estate into its parts — the specific gifts first, then the residue that carries the remainder. It shows why the residue clause matters most: it is usually the largest slice, and the one a hurried will most often forgets.
