Types of will
In Brazil, the Civil Code (Law no. 10.406/2002) provides the public will (drawn up at a notary), the sealed will (written and approved by the notary) and the holographic will (written by the person, with witnesses). In Portugal, the Civil Code provides the public and the sealed will.
Each type has its own formal requirements. A defect of form can invalidate the will — which is why careful drafting is essential.
