MEMORANDUM **

Stephen B, Turner appeals pro se from the district court’s order denying his motion to modify a settlement agreement and request to vacate the 'order dismissing his underlying 42 U.S.C. § 1983 action in light of that settlement agreement. We have jurisdiction under 28 U.S.C. § 1291. We *581 review for an abuse of discretion a denial of motion for relief from a final judgment or order. Casey v. Albertson’s Inc., 362 F.3d 1264, 1257 (9th Cir. 2004). We affirm.

The district court did not abuse its discretion in denying Turner’s motion to modify the settlement agreement and vacate the order of dismissal because Turner failed to file these motion within 180 days, as required by the order of dismissal. See Fed. R. Civ. P. 60(c)(1) (motions to vacate an order under Rule 60(b) must be brought “within a reasonable time”); see also Ahanchian v. Xenon Pictures, Inc., 624 F.3d 1253, 1255 (9th Cir. 2010) (describing district court’s wide discretion in case management and obligation “to secure the just, speedy, and inexpensive determination of every action” (citation and internal quotation marks omitted)); Latshaw v. Trainer Wortham & Co., Inc., 452 F.3d 1097, 1101 (9th Cir. 2006) (attorney mistakes are more appropriately addressed through malpractice claims, not Rule 60(b)(1) motions).

We do not consider allegations raised for the first time on appeal. See Padgett v. Wright, 587 F.3d 983, 985 n.2 (9th Cir. 2009).

AFFIRMED.
