Marking the boundary between plots in Portugal

Independent site: we are not a public authority, and this is not legal or tax advice.

Any owner can require the neighbouring owners to take part in marking the boundary between the plots (demarcação), and this right never expires (Código Civil, arts. 1353.º and 1355.º).
