(1) The customer is obliged to accept the work that has been produced as contractually agreed, except to the extent that, in view of the nature of the work, acceptance is excluded. Acceptance may not be refused by reason of trivial defects.
(2) A work is considered accepted also if, following completion of the work, the contractor has set a reasonable period to the customer for its acceptance and the customer has not refused to accept the work within that period, citing at least one defect in the refusal. Where the customer is a consumer, the legal consequences of sentence 1 arise only if the contractor has made the customer aware, together with the demand for acceptance, of the consequences that failure to declare the refusal of acceptance, or failure to cite defects in refusing acceptance, will have; such notification must be in text form.
(3) If the customer accepts a defective work under subsection (1) sentence 1 even though they know of the defect, they only will be entitled to the rights designated in section 634 nos. 1 to 3 if they reserve their rights with regard to the defect in accepting the work.
