B. On motion of a party made not later than thirty (30) days

after a judgment, decree, or appealable order prepared in

conformance with Section 696.3 of this title has been filed with the

court clerk, the court may correct, open, modify, or vacate the

judgment, decree, or appealable order. If the moving party did not

prepare the judgment, decree, or appealable order, and Section 696.2

of this title required a copy of the judgment, decree, or appealable

order to be mailed to the moving party, and the court records do not

reflect the mailing of a copy of the judgment, decree, or appealable

order to the moving party within three (3) days, exclusive of

weekends and holidays, after the filing of the judgment, decree, or

appealable order, the motion to correct, open, modify, or vacate the

judgment, decree, or appealable order may be filed no later than

thirty (30) days after the earliest date on which the court records

show that a copy of the judgment, decree, or appealable order was

mailed to the moving party. The moving party shall give notice to

all affected parties. A motion to correct, open, modify, or vacate

a judgment or decree filed after the announcement of the decision on

all issues in the case but before the filing of the judgment or

decree shall be deemed filed immediately after the filing of the

judgment or decree.

C. If more than thirty (30) days have passed since the filing

of a judgment, decree, or appealable order, proceedings to vacate or

modify the judgment, decree, or appealable order shall be by

petition in conformance with Section 1033 of this title unless

approved by all parties who have entered an appearance in the

lawsuit.

D. The party that prevails in an action to vacate any judgment,

decree or appealable order shall only be considered the prevailing

party for the purpose of the award of costs, to include a reasonable

attorney fee, if such party prevails on the merits in the underlying

action.
