Namoxy will contact you for the transfer of domain ownership. This entails transferring the domain to your registered account of a domain registrar like GoDaddy, Namecheap, Dynadot & more. Once, the process is complete, the ownership is transferred to you.
In case the domain is bought in instalments, the process is slightly different. You will be allowed to use the domain but the ownership will be transferred only after the amount is fully paid.
