So far I have not found any definitive answer. A great deal depends on the context. In real estate, deed of conveyance seems to be appropriate. I have found certificate of acceptance used with computer texts.

A Deed of Assignment is a document or agreement which an assignor (the transferor) states his promise that from the date of the assignment or any date stipulated therein, the assignor assigns his ownership in that property to the assignee (transferee). A simple illustration would be when the developer signs a Deed of Assignment to transfer their ownership of that piece of property to the purchaser. When that purchaser decides to sell that property to a subsequent purchaser and the Document of Title has yet to be issued, the purchaser will sign a Deed of Assignment assigning his rights under the original Deed of Assignment to the subsequent purchaser. This will go on until the Document of Title is issued.
