Q: What if I am living somewhere else temporarily due to legitimate reasons, like when I am renovating my home?
A: As the law does not specifically define a "place of residence", what constitutes an offence is judged on a case-by-case basis and is subject to the investigator's assessment whether a person has committed an offence or not. If a person has the intention of going back to the registered address, he or she is unlikely to be viewed as an offender.
National Registration Act 1965
“residential address”, in relation to an individual, means the individual’s usual or last known place of residence in Singapore.
