It is not something that comes up often, but I have seen cases where a client profile appears to belong to someone very young. Most platforms have age requirements for freelancers, but I am less sure about what rules exist for clients. If a minor is the one hiring and paying, it could create complications around contracts, payments, and responsibilities. Do the platforms you use have any clear policy about whether a minor is allowed to act as a client and hire freelancers for paid work?
