Yes, it's possible. For example if the tenant him/herself is underaged or has some marks on his/her credit or enforcement register, then the only way to use Igglo Vuokravakuus service to deliver the deposit for the landlord is that someone else will take the service on his/her name. Then this person just orders the service normally through the app, and fills in the information about the landlord and apartment where the deposit is supposed to be taken to.
In that case, it’s good to remember that the person who takes the service on his/her name is then, from Igglo’s point of view, personally responsible for all the possible upcoming costs regarding the actual tenant’s deposit rent. The person who is ordering the service could write in the deposit's information after the address for example something like: "The service is taken for my sister (name of the actual tenant)."
