whether copy of servic of contract is requird to serve the opposite party.

What are the facts of case ?

Nothing can be presumed.

What is the problem in providing a copy to the other party?

In response to your query, 

Although your facts are not clear I am this will be helpful for you to understand whether you have to serve a copy or not. 

Prior to the filing of a lawsuit, a notice is issued. The major goal is to resolve the problem at the outset rather than taking it to court for a long and drawn-out legal battle. The rule of serving notice is eased in certain instances where the party has suffered irreparable harm and the court is convinced. In such circumstances, an injunction order, which is a temporary order, will be issued.

In order to properly serve a notice, the client must also supply the advocate with correct and accurate information. If the receiving party fails to react within the stipulated period, the sending party has the right to launch a lawsuit; alternatively, if the receiving party receives notice and is dissatisfied with the response, he can still initiate a lawsuit.

As you can read here that every possible document related to the case of having any sort of significance has to be added to the notice therefore if the copy of servic of contract is related to the case then you must add it to the notice.
