After creating,let's say a new unif. title for a work, such as splitting a currently used dual language unif. title, is the creator of the auth. record obligated to change the entries to the record from which old  unif title was derived?

Also if the unif. title is under an author, would there be 240 10 title. English and then a 700 10  Name. Title. Latin.
Or are there two 7XXs instead??  This latter question has been just discussed.  I thought when unif. titles were split, one was a 240, the other is a 7XX.
