I wrote the below code

    from sympy.core import Basic
    class MyType(Basic, ):
        pass
    class MyAskHandler(AskHandler, ):
        @staticmethod
        def MyType(expr, assumptions):
            return True
    a = MyType()
    register_handler(Q.prime, MyAskHandler)
    assert (ask(Q.prime(a)) is True)
