Change owner of User Defined Data Types

Please let me know if there is a method for changing the owner of existing User Defined Data Types. I cannot drop and recreate them as the datatypes are in use.
Thanks.Try, sp_changeobjectowner.
Refer to BOL for more information.|||sp_changeobjectowner cannot be used to change the owner of UDTs as it only works with tables, views, user-defined functions and stored procedures.|||Then only way is drop and recreate.|||As I stated in my original post, it is not possible to drop them as they are in use.|||Use specified SP to change owner for that table, which would be applied by default. Apart from this I have no other idea.
