Neighbour disputes lawyer in São Paulo, Brazil
Noise, damp, boundary walls, trees and irregular building work next door — settled by notice, through the authorities or in court. In person on Avenida Paulista or remotely.
5,0 · 18 Google reviewsThe Brazilian Civil Code does not forbid annoying your neighbour — it forbids going beyond the ordinary limits of tolerance. Art. 1.277 gives the owner or possessor the right to stop interference harmful to safety, quiet enjoyment and health, weighing the nature of the use, the location of the building and the zoning rules. That is why work at ten in the morning and music at two get different answers.
The disputes that reach us most often.
- Noise and abnormal useMusic, parties, machinery, a workshop in a residential street. The yardstick is art. 1.277: interference beyond what the location tolerates.
- Damp coming from next doorAnyone whose works endanger the adjoining building must carry out protective works first (art. 1.311) and is liable to demolish and pay damages (art. 1.312).
- Boundary walls and fencesThe adjoining owner can be compelled to demarcate; dividing walls are presumed common, and the cost is shared between them (art. 1.297).
- Trees on the boundaryA trunk on the line makes the tree common (art. 1.282); overhanging roots and branches may be cut by the invaded owner (art. 1.283); fallen fruit belongs to the owner of the land below (art. 1.284).
- Irregular windows and balconiesNo window, roof terrace or balcony may be opened less than a metre and a half from the neighbouring land (art. 1.301) — and removal can only be demanded within a year and a day of completion (art. 1.302).
- Water, smoke and smellsWater discharged next door (art. 1.300), chimneys and ovens set against the dividing wall (art. 1.308), a polluted well (art. 1.309).
- Access and servicesLandlocked property has a right of way against payment (art. 1.285), and cables and pipes may cross a neighbouring plot in the situations set out in art. 1.286.
Ordinary tolerance, evidence and time limits.
Almost every case turns on three points. The first is degree: it is not enough to say the neighbour is a nuisance; the interference has to exceed what is tolerated in that street, at that hour. A bar on a commercial road and a bar under a bedroom window are different cases.
The second is evidence, usually lost through carelessness: decibel readings, an engineer's report tracing the damp, a notarial record, dated photographs, complaints logged with the building manager and the council. The law also allows entry onto the adjoining property, on prior notice, where essential for repairs or cleaning — with compensation for damage caused (art. 1.313).
The third is the time limit. Against a window, balcony, terrace or gutter opened over your property, removal may be demanded only within a year and a day of completion (art. 1.302). Building is free, but subject to the rights of neighbours and to administrative regulations (art. 1.299) — municipal zoning counts.
It helps to separate neighbour law from what it is not. If the neighbour has taken part of your land, the question stops being tolerance and becomes possession — covered on the repossession page. If the doubt is where the registered boundary actually runs, the route is usually a boundary rectification, dealt with under property regularization.
How we run the case.
- Classifying the disputeWe settle whether the case is abnormal use, irregular building, boundary or possession. That classification changes the remedy and the time limit.
- Producing the right evidenceA notarial record, noise measurement, a technical report on the damp or a boundary survey, according to the dispute.
- Notice and settlementA notice setting out the legal basis resolves a good share of cases and, where it does not, organises the evidence for court.
- Using the right authorityBuilding manager, borough council, environmental agency or health authority, where the administrative route is faster.
- Court proceedingsAn order to stop the interference, backed by a daily penalty, demolition of irregular works and damages.

Meet Letícia MarquesCommon questions.
Can noise from a neighbour really end up in court?
It can, where it goes beyond the ordinary limits of tolerance for that location. Art. 1.277 of the Civil Code allows interference harmful to safety, quiet enjoyment and health to be stopped, weighing the nature of the use and the location. Technical evidence therefore beats an isolated complaint.
The damp comes from the flat above. Who do I sue?
Whoever caused the damage, and the technical report decides that — the neighbour, the building itself where the source is in common parts, or the developer in a new block. Anyone whose works endanger the adjoining property must carry out protective works first (arts. 1.311 and 1.312).
Who pays for the wall between two plots?
As a rule, both. Art. 1.297 lets an owner fence, wall or ditch the property and compel the adjoining owner to demarcate, dividing walls being presumed common with the cost shared. It is worth confirming where the registered boundary runs first.
My neighbour opened a window facing my house. Can I have it closed?
If it is less than a metre and a half from your land, yes — that is what art. 1.301 prohibits, with 75 centimetres for oblique openings. But there is a deadline: removal of a window, balcony, terrace or gutter can only be demanded within a year and a day of the works being completed (art. 1.302).
What does resolving a neighbour dispute cost?
It depends on the route. Notice and negotiation cost far less than litigation and settle a good share of cases. In court there are fees agreed in writing, court costs on the value of the claim and the cost of technical evidence. The proposal follows the review, in writing.
Do you act outside São Paulo?
Yes. The claim runs in the forum where the property sits, and we handle cases elsewhere with local agents under our instruction. Meetings are held at our Avenida Paulista office or by video call.
Is the problem the neighbour, or the neighbour's building work?
Describe the situation and send whatever you have recorded. We will say how it is classified, what evidence is missing and whether interim relief is available.
