Dear Nisa,
In order to make the agency/broker agreement and POA valid and enforceable if we need to use it in the court, please check on the following :
1. Do we need to stamp/put duty stamp on the agreement and POA?
2. Do we need to register the agreement and POA with the authority?
3. Do we need to have the agreement and POA notarised by the notary public?
4. Do we need to have the agreement and POA endorsed by the local authority?
