If two business identities in good spirit decide to make and an agreement they are free to do so, also without the interference of and lawyer.
Though there is a few laws you must follow:
Købeloven (The Sale of Goods Act ), funktionærloven (The Salaried Employees Act), lejeloven (Rent Act) and a few others are laws which companies always must follow.
If you conclude an agreement with another company for cooperation within the
sale of services or other issues you should prepare a written agreement.
Describe in the agreement as clearly as possible what you are cooperating about.
Describe in the agreement e.g.:
You do not have to involve a lawyer to draw up the agreement to make it legally binding. Either both companies´ signature or an email from both companies confirming the content of the agreement is sufficient.
For complicated agreements, it is an advantage to involve a lawyer for advice. The lawyer can ensure that all areas are covered, and perhaps the lawyer´s interference ensures greater respect for the agreement from both parties.
An oral agreement is a valid contract - if it can be proven. Have you agreed on something orally with a partner so hurry up and write it down and send an email to make sure that you have understood the oral agreement in the same way.
If an oral agreement must be enforceable it should be confirmed in writing.
Never interrupt your enemy when he is making a mistake.
