Intellectual property rights give the creator or owner the exclusive right to use the intellectual property and to earn money from it.
Even if someone has created a piece of work for you or for your business, you don’t automatically own it unless the IPRs have been transferred in full to you.
Arranging to have the rights assigned to you is something you should consider, particularly if you’ve had help from friends and family, or you're using freelancers or contractors who haven’t signed a Consultancy Agreement or Employment Agreement with you.
