ORDER

DALE A. DROZD, Magistrate Judge.

Plaintiff is a state prisoner proceeding pro se and in forma pauperis. Plaintiff seeks relief pursuant to 42 U.S.C. § 1983. Pending before the court is plaintiff's motion to amend and plaintiff's proposed fourth amended complaint.

On May 26, 2015, this court ordered service of plaintiff's third amended complaint on defendants. On July 1, 2015, plaintiff filed the pending motion to amend his complaint to add two Doe defendants, namely, a John Doe (Records Department Personnel) and John Doe (Records Department Supervisor) to his complaint. Plaintiff does not seek leave to add any new causes of actions against any of the named the defendants. He only wishes to assert his existing access to courts claim against the Doe defendants.

The court will deny plaintiff's motion to amend without prejudice. Plaintiff is advised that this court cannot order service of plaintiff's complaint on any defendant not actually identified by name in his complaint. When plaintiff discovers the identity of his John Doe defendants, he may file a new motion to amend, together with a proposed amended complaint.

Also pending before the court is defendant Obert's motion for an extension of time to file a response to plaintiff's third amended complaint. Good cause appearing, the court will grant defendant's request.

Accordingly, IT IS HEREBY ORDERED that:

1. Plaintiff's motion to amend (Doc. No. 35) is denied without prejudice;

2. Defendants' motion for an extension of time to file a responsive pleading (Doc. No. 36) is granted; and

3. Within thirty days from the date of this order, defendant shall file a response to plaintiff's third amended complaint.
