[¶ 1] Earl St. Claire appealed from a district court judgment requiring him to pay $135 per month for child support. He was ordered to pay $945 to the Ward County Social Service Board for suрport it provided from December 2002 through June 2003, and $27 per month commencing July 1, 2003, for any arrears not paid in full. We affirm.

[¶ 2] Earl and Joeletta St. Claire are married, but separated. Thе couple has one child who lives with Joeletta St. Claire. Earl St. Claire is currently incarcerated in Minnesota. The Minot Regional Child Support Enforcement Unit (“Unit”) and Joeletta St. Clаire brought an action seeking an order establishing Mr. St. Claire’s child support obligation, reimbursement for past support provided by the Unit, and a decision regarding health insurance for the child. Mr. St. Claire requested an *177 extension of time to file a response or, if no extension was granted, asked the district court to appoint counsel to represent him in thе matter. His request for an extension was granted, and the district court did not appoint counsel to represent Mr. St. Claire. After Mr. St. Claire filed a response, trial was scheduled for Junе 23, 2003.
[¶ 3] In its Order for Trial, the district court stated Earl could appear at the trial by telephone conference and listed the number he needed to call at the scheduled time. On June 8, Mr. St. Claire wrote a letter to the district court claiming his caseworker at the correctional center would not allow him to appear by telephone without a letter from the court. The district court sent a letter dated June 18 to the caseworker informing her of the hearing and requesting that the appropriate arrangements be mаde in order for Mr. St. Claire to appear by telephone.
[¶ 4] On the day of the trial Mr. St. Claire did not appear by telephone. The court proceeded with the ease and received evidence from the Unit. Judgment was entered on July 22, setting Mr. St. Claire’s child support obligation and requiring it to be withheld from his income. The district court imputed income to Mr. St. Claire based upon minimum wage, made a deduction for support of another child with another mother, and determined he owed $135 per month in child support. It further required him to pay Ward County Social Service Board $135 per month for amounts it expended in support of the child from December 2002 through June 2003, and beginning in July 2003, he was ordered to pay $27 per month until any arrears were paid in full.

[¶ 5] On appeal, Mr. St. Claire contends he was denied due process under the Fifth and Fourteenth Amendments of the United States Constitution because he informed the district сourt that the Minnesota Department of Corrections would not allow him to appear by telephone and he would not waive his right to be present for the trial. He claims thе district court should have rescheduled the trial so he could argue his own defense. There are two types of due process, substantive and procedural. Mr. St. Claire’s claim that he was denied the right to be present to argue his own defense involves procedural due process.
[¶ 6] Although prisoners have diminished constitutional protections, they maintain a due.process right to reasonable access to the courts.
In re Adoption of J.S.P.L.,
[¶ 7] The requirements of due process are flexible and vary dеpending upon the circumstances of each case.
[¶ 8] Mr. St. Claire’s claim that his due process rights were violated presupposes that the district court was obligated to ensure his presence at trial. However, the district court did not have a duty to ensure Mr. St. Claire’s presence at the trial, tele-phоnically or otherwise.
See Jones v. Bowens,
[¶ 9] Mr. St. Claire claims he was harmed by not being ordered to pay more child support. “A person legally responsible for thе support of a child ... and who fails to provide support ... is liable for the reasonable value of physical and custodial care or support which has been furnished tо the child by any ... county social service board.” N.D.C.C. § 14-08.1-01. It is necessary to apply the child support guidelines to a case involving an incarcerated obligor.
Surerus v. Matuska,
*179
[¶ 10] Mr. St. Claire further claims the judgment harms him because under Minnesota law he could have more money-withheld from his income thаn he could under North Dakota law. This argument is unavailing because, under N.D.C.C. § 14-12.2-33.1(4), Mr. St. Claire’s employer is required to comply with the law in the state of the obligor’s principal place of employment with regard to the maximum amount that may be withheld.
See also
Minn.Stat. § 518C.5025(d). Additionally, the district court judgment only set Mr. St. Claire’s minimum monthly obligation for child support. There is nothing preventing him from paying more рer month for child support or arrears. In this respect, any harm resulting from appellant’s absence in this proceeding is arguably harmless.
See
N.D.R.Civ.P. 61 (“no error or defect in any ruling or order or in anything done or omitted by the court or by any of the parties is ground for granting a new trial or for setting aside a verdict or for vacating, modifying or otherwise disturbing a judgment or order, unless refusal to take such action appears to the court inconsistent with substantial justice”);
see also Jones,
[¶ 11] We hold Mr. St. Claire’s right to due process was not violated by the district court. Mr. St. Claire’s remaining arguments are either without merit or not appropriately addressed in an action solely to determine his child support obligation. Accordingly, we affirm.
