Subject: Tree pruning
Dear Sir or Madam,
I am taking the liberty of contacting you because I notice that the branches of your trees are protruding onto my property.
The article 673 of the Civil Code allows me to force you to cut these branches, I thus ask you to prune these trees as soon as possible.
If you fail to do so, I will have to take the matter to the local court to assert my rights.
In the expectation of an amicable solution, please accept, Madam, Sir, the assurance of my distinguished consideration.
