The LIGO Scientific Collaboration (LSC) is developing and running analysispipelines to search for gravitational-wave transients emitted by astrophysicalevents such as compact binary mergers or core-collapse supernovae. However,because of the non-Gaussian, non-stationary nature of the noise exhibited bythe LIGO detectors, residual false alarms might be found at the end of thepipelines. A critical aspect of the search is then to assess our confidence forgravitational waves and to distinguish them from those false alarms. Both the'Compact Binary Coalescence' and the 'Burst' working groups have beendeveloping a detection checklist for the validation of candidate-events,consisting of a series of tests which aim to corroborate a detection or toeliminate a false alarm. These tests include for example data quality checks,analysis of the candidate appearance, parameter consistency studies andcoherent analysis. In this paper, the general methodology used for candidatevalidation is presented. The method is illustrated with an example of simulatedgravitational-wave signal and a false alarm.
