Amazon Route 53 supports Domain Name Transfer between AWS accounts

Amazon Route 53 Domains now lets you transfer domain registrations between AWS accounts using the Route 53 API.

Previously, this operation required you to open a support ticket. Now, you can transfer your domains from one AWS account to another as a self-service operation. This operation is free of charge and does not affect either the renewal date or the contact details of your domain name registration. To learn more, visit the Route 53 Developer Guide.
