Neighbour disputes lawyer in São Paulo, Brazil
Noise, damp, boundary walls, trees and irregular building work next door — assessed for formal notice, administrative action or court proceedings. 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. Timing matters, but daytime activity can also exceed legal limits.
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 doorWorks threatening the adjoining building require preventive measures (art. 1,311), without excluding damages. Demolition for breach of statutory prohibitions requires assessment of the case (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 boundary creates a presumption of joint ownership (art. 1.282); encroaching roots and branches may be cut up to the vertical boundary plane, subject to environmental rules (art. 1.283); fruit falling onto private land belongs to that landowner (art. 1.284).
- Irregular windows and balconiesThe general 1.5 m rule has 75 cm cases and exceptions for small light or ventilation openings (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.
Article 1,302 is not a universal deadline for irregular works or damages. Entry under art. 1,313 requires notice and necessity; it does not authorize forced entry. The shared-wall presumption can be rebutted and does not justify charging half of any unilateral project. Natural water flow differs from direct discharge. Article 1,286 concerns underground public-utility conduits when alternatives are impossible or excessively costly.
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. A registry-description error may require rectification; a disputed boundary may require demarcation, assessed 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 reasoned notice proposes a solution and records the dispute; it guarantees no agreement and does not replace urgent relief.
- 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?
Yes, where interference exceeds ordinary tolerance and harms safety, peace or health under art. 1,277 of the Civil Code. Use, location and zoning matter. Measurements and other records help; no type of evidence automatically prevails, and daytime is not a licence for unlimited noise.
The damp comes from the flat above. Who do I sue?
The cause and legal responsibility must be assessed: a neighbour, the condominium for common installations, a developer or another responsible party. A technical report helps establish the cause but does not alone determine liability. Preventive measures under art. 1,311 do not exclude compensation for damage.
Who pays for the wall between two plots?
Dividing walls are presumed jointly owned unless proved otherwise. Article 1,297 provides equal contributions to construction and upkeep under local custom, but special fences and extensions have separate rules. Check the boundary, ownership and works; a unilateral project does not automatically entitle its owner to half the cost.
My neighbour opened a window facing my house. Can I have it closed?
It depends on the opening. Article 1,301 generally requires 1.5 m and 75 cm for windows not overlooking the boundary or perpendicular windows. Light or ventilation openings no larger than 10 × 20 cm and more than 2 m above each floor are exempt. Article 1,302 provides a year and a day from completion for the removal it regulates, not a universal damages deadline. Rural land also requires checking art. 1,303.
What does resolving a neighbour dispute cost?
It depends on the route, complexity and evidence. Costs may include notices, legal fees, court charges and expert evidence. Negotiation guarantees neither agreement nor lower cost in every case. A written proposal follows the assessment.
Do you act outside São Paulo?
Yes, with meetings on Avenida Paulista or by video and local support where needed. Venue depends on the action: real-property claims concerning neighbour rights follow the property location under art. 47 CPC; other claims require their own jurisdictional analysis.
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.
