A natural or legal person, not being the author of the work, may be the owner of the work. The patrimonial rights might be transferred to him / her by means of a contract between the author and the respective third party, being (i) an assignment agreement or (ii) a contract of work by order (fulfillment of a contract of services or employment).
In the latter case, the author is the original owner of the patrimonial and moral rights, but it is presumed, unless otherwise agreed, that the patrimonial rights over the work have been transferred to the employer to the extent necessary for the exercise of his usual activities at the time of creation of the work.
The transfer of patrimonial rights due to the death of the author will occur by testamentary or intestate succession.
