As most Owners do not hold updated copies of these documents in their possession you are well advised to consult your Lawyer BEFORE you instruct any Agents and ask them for updated copies of these documents OR if you have the energy and knowledge visit the Camara and Finance Departments yourself and make the necessary requests as this normally takes several days for the updated documents to be produced. The registration certificate and caderneta predial should have been obtained or validated less than 6 months ago. The other documents do not have a validity date.
There is one important issue which must be looked at in some depth and this is the question of Habitation Licences, especially for older properties. Recent changes in legislation has caused problems as to whether a Habitation Licence is required for a property. A house either has a Habitation Licence or a Certificate, issued by the local Camara, confirming that it does not require one. Only the Camara can certify this situation. The requirement of Habitation Licences was introduced by Decree - Lei 38/382 dated 7th August 1951 therefore houses built before that date are not required to have Habitation Licences.
As the current building regulations become stricter the Notaries were advised that they should require an updated Certificate from the Camara to ascertain that there were no unlicensed alterations to the properties being sold. Historically the system had been badly abused in that the method of proving that a house did not require a Habitation Licence was flawed. Many people purchased houses still registered as old cottages which in fact had been improved, renovated and sometime completely rebuilt - without proper licences.
