Horse-racing rules
How do I settle a Lucky 15 when one horse is a non-runner?
Direct answer
A Lucky 15 comprises 4 singles, 6 doubles, 4 trebles and 1 fourfold. When a selection is void, each affected combination reduces under the operator’s terms; other selections keep their original status.
How to use this answer
A definitive win, loss, void or refund cannot be established from the question alone. Identify the operator, the exact market, the date and the relevant official result, then check the rules that applied to the bet.
Treat the void selection according to the bookmaker's accumulator-reduction terms and re-evaluate each unaffected combination.
Racing bets can have different dead-heat, withdrawal, non-runner and each-way settlement conditions. Confirm the race time, final official result and the operator’s rule that applied when you placed the bet.
