However, non-competition obligations can normally only be agreed for a five-year period on the basis of EU competition law (for a post-contract non-competition obligation, see below). The five-year period can be extended by mutual agreement for a further five years. If the parties fail to reach an agreement on the amount of the claim, this amount is appropriately set by a court, taking into account all the circumstances of each case and, in particular, the commission lost by the sales agent. In the absence of a contractual agreement to the contrary, Portuguese law does not provide for a post-contractual non-competition obligation of the sales agent. However, Portuguese law authorizes an agreement on such a post-contractual non-competition obligation imposed by the commercial agent for a maximum of two years, calculated from the end of the agency agreement. It should be noted that the commercial agent is entitled to appropriate financial compensation if such a post-contract non-competition obligation has been agreed (unless the client waives this obligation in writing before the end of the contract). Under Portuguese law, there is a general obligation to correctly answer questions and provide certain important information without a specific request before an agreement is reached (doctrine of culpa in contrahendo). It is assumed that a Supreme Court decision of October 23, 2014 ended the discussion of the commercial agent`s request for the sales agent if the client did not terminate the commercial agency contract and the obligation to compensate the sales agent for the customer that the agent received as a result of the performance of the contract for the client. In addition, agreements on the quantities of products that the distributor must obtain from the client are subject to EU competition law: contractual provisions requiring the distributor to purchase 80% or more of its product application exclusively from the client can only be agreed for a period of five years.
