*Only a registered surveyor licensed by the Land Surveyors Board Singapore is legally permitted to carry out survey work in Singapore. As such, be sure that your survey plan bears the endorsement of a Registered Surveyor with a Practicing Certificates. Beware of persons or companies offering to survey your land on the basis of an ?arrangement? with a Registered Surveyor. The law only allows Registered Surveyors to employ subordinates but should be under direct supervision. Thus it is better to deal with the Registered Surveyor and make payments for services only to the Registered Surveyor's firms. This will ensure a legal contract between the professional and you.
