Why these exist
Every one of these guides started as a mistake. A policy that lapsed because the
reminder mail went to Promotions. A warranty that ran out eleven days before the
thing broke. An annual plan that renewed for a third year running.
None of it is complicated. That is the frustrating part — these are not hard
problems, they are invisible ones, and they stay invisible right up until the
moment they cost you. Writing them down is most of the fix, and it does not
matter whether you write them in an app, a spreadsheet or the back of a diary.
Everything here is general information, not professional advice, and rules change —
several of these vary by state. Check the current position with the RTO, your
insurer or your bank before you act on a number. Where a figure comes from a
specific rule, the guide says which one, so you can verify it yourself.
