Inre S.J.F., 2000 ND 158, ¶ 22, 615 N.W.2d 533. A

[¶ 20] Whether a change of venue is required to obtain a fair and impartial trial is a question of fact, and we will not overturn a trial court's decision granting or denying a motion for change of venue unless the court abused its discretion. Eckman v. Stutsman County, 1999 ND 151, ¶ 7, 598 N.W.2d 494. A trial court abuses its discretion when it acts in an arbitrary, unreasonable, or unconscionable manner, or when its decision is not the product of a rational mental process leading to a reasoned determination.In re S.J.F., 2000 ND 158, ¶ 22, 615 N.W.2d 533.

"The determination of back child support under N.D.C.C. § 14-17-14(4) lies within the trial court's discretion, and its decision will be reversed on appeal only if the court abused its discretion."

A trial court abuses its discretion only when it acts in an arbitrary, unreasonable, or unconscionable manner, or when its decision is not the product of a rational mental process leading to a reasoned determination.

[¶ 30] Interpretation of a judgment is a question of law, which is fully reviewable on appeal. In re S. J. F., 2000 ND 158, ¶ 14, 615 N.W.2d 533; Jorgenson v.

Moreover, if Kristy had established Joseph's child support obligation established when Dylan was born in 1997, Joseph's child support obligation would have likely been higher because his income was higher. See Dep't of Human Servs. v. Bell, 711 A.2d 1292, 1295 (Me. 1998) (stating laches did not apply in child support recovery action because "had the Department brought the action earlier, Bell's total obligation would have exceeded that which he owes in the present circumstances"); In re S.J.F., 615 N.W.2d 533, 538 (N.D. 2000) (stating benefit of delay inured to the benefit of the obligor because he did not have to pay child support during the period of the delay). In sum, Joseph has failed to show prejudice by clear and convincing evidence, and he cannot avail himself of the defense of laches.
