carta registada com aviso de receção

carta registada com aviso de receção (registered letter with proof of delivery)
A letter for which the post office takes the recipient's signature and returns a tear-off slip to the sender showing the delivery date. Portuguese law often requires exactly this kind of letter: a landlord uses one to tell a tenant the terms of a sale of the property (Article 1091.º(4) of the Civil Code), and it is also used for notices of contract termination and rent increases. The deadline for a reply runs from the day of delivery, not the day of sending.
Where you come across it. A CTT post office; letters from your landlord, your telecoms provider or a public body; correspondence before going to court.
The tear-off slip (aviso de receção) is the only proof that the letter arrived and of exactly when; keep it together with a copy of the letter itself.
