[¶ 1] Janice Piatz and Rebecca Johnson appeal from the trial court’s judgment dismissing their claims against Austin Mutual Insurance Company for breach of contract and bad faith. We affirm.
I
[¶ 2] On July 2, 1997, Janice Piatz and her daughter, Rebecca Johnson, were both injured in an accident when a Barnes County mower tractor made a sudden left turn in front of them pickup on a highway near Sanborn, North Dakota. Both Piatz and Johnson sustained injuries from the collision. Piatz and Johnson had insurance coverage issued by Austin Mutual Insurance Company. The policy provided standard no-fault coverage in the amount of $30,000 per person.
[¶ 3] Piatz and Johnson submitted claims for no-fault benefits with Austin Mutual. Between July 2, 1997, and May 26, 1998, Austin Mutual paid Piatz $11,629.95 and Johnson $6,749.72 for medical expenses. Austin Mutual also paid Piatz $5,055.23 and Johnson $409.75 for their wages lost during the same period. On June 30, 1998, Austin Mutual sent a letter to Piatz and Johnson terminating their benefits. This letter was based on the opinion of Dr. Robert Fielden, who, after conducting an individual medical examination, determined Piatz did not require any treatment beyond six to eight weeks following the accident, and Johnson did not require any further treatment beyond four to six weeks following the accident.
[¶ 4] Piatz and Johnson sued Austin Mutual claiming breach of contract and bad faith. On the morning of the trial, the trial court informed the parties it was bifurcating the claim for breach of contract from the claim for bad faith. Plaintiffs then waived the jury on the breach of contract claim, and that claim was tried to the court on December 11 through 13, 2000. On February 5, 2001, the trial court issued its findings of fact, conclusions of law, and order for judgment, concluding neither Piatz nor Johnson were entitled to benefits for expenses incurred after May 26, 1998. A judgment of dismissal of their claims was entered March 19, 2001. Piatz and Johnson appeal.
II
[¶ 5] Piatz and Johnson argue the trial court abused its discretion when, on its *685 own motion, it bifurcated trial of the breach of contract and bad faith claims. Piatz and Johnson claim the trial court’s order did not further the convenience of the parties because all the exhibits and testimony would have to be submitted anew in the second trial. They contend the decision did not advance fairness, justice, or judicial economy, and it caused considerable inconvenience and expense.
[¶ 6] A trial court’s ruling on bifurcation of trials under N.D.R.Civ.P. 42(b) will not be overturned on appeal unless the complaining party demonstrates the court abused its discretion.
See Praus v. Mack,
[¶ 7] A touchstone for an effective appeal on any proper issue is that the matter was appropriately raised in the trial court so the trial court could effectively rule on it.
State v. Freed,
[¶ 8] We have not had the opportunity prior to this case to address a
sua sponte
order of bifurcation. Because N.D.R.Civ.P. 42(b) is virtually identical to the similar federal rule from which it was derived, this Court will look to relevant federal caselaw construing the federal rule for guidance in construing our own rule.
Kiker v. Walters,
[¶ 9] In the present action, Piatz and Johnson admit in their brief they failed to object to the trial court’s decision to bifurcate the issues of breach of contract and bad faith. Piatz and Johnson argue their failure to object does not amount to a waiver. They claim that under N.D.R.Civ.P. 46, an objection was unnecessary because they were not given an opportunity to object.
[¶ 10] The relevant portion of N.D.R.Civ.P. 46 provides, “if a party has no opportunity to object to a ruling or order at the time it is made, the absence of an objection does not thereafter prejudice the party.” The transcript provided by Piatz and Johnson does not include the trial court’s ruling on bifurcation. Without a transcript of the trial court’s ruling, we are unable to determine that the trial court did not allow Piatz and Johnson an
*686
opportunity to raise a proper objection. Unless the record affirmatively shows the occurrence of the matters which the appellant relies upon for relief, the appellant may not urge those matters on appeal.
City of Grand Forks v. Dohman,
Ill
[¶ 11] Piatz and Johnson claim Austin Mutual’s initial payments for medical expenses were made when it had access to both Piatz and Johnson’s medical records. Therefore, they argue Austin Mutual waived its defense that continued claims for benefits were not reasonable or necessary because Austin Mutual had made prior payments. We disagree.
[¶ 12] Piatz and Johnson’s argument is contrary to the public policy behind North Dakota’s no-fault statute, N.D.C.C. ch. 26.1-41. No-fault insurance was designed to encourage quick, informal payments to assure injured plaintiffs are compensated for their injuries.

Jean Appleman,

§ 5162, at 441 (2002);
see also Aponte-Correa v. Allstate Ins. Co.,
[¶ 13] Similar arguments have been raised in the workers’ compensation arena.
See e.g. Childs v. Copper Valley Electric Ass’n,
[¶ 14] In
Childs,
the plaintiff argued that because the employer had paid initial medical bills, the employer was estopped from denying any further liability.
*687 [¶ 15] We find the rationale in these cases supports our rejection of the plaintiffs’ argument in the present case. Austin Mutual paid no-fault benefits for claims submitted by Piatz and Johnson. After a period of time, questions were raised about reasonableness and necessity of continued treatment. Austin Mutual conducted an independent medical examination and determined no further benefits were necessary. To hold that Austin Mutual waived its defense regarding the necessity of continued medical care by initially paying no-fault benefits would encourage insurance carriers to examine and litigate every claim before any benefits were paid. This is contrary to the rationale and public policy of the no-fault statutes.
IV
[¶ 16] Piatz and Johnson argue the trial court erred in excluding evidence of Dr. Fielden’s prior independent medical examinations. Piatz and Johnson offered Dr. Fielden’s answers to interrogatories from a prior case to indicate he performed an average of approximately 1,200 individual medical examinations and earned over $500,000 per year. The trial court refused to take judicial notice of this document, ruling there had not been sufficient foundation established.
[¶ 17] A trial court’s decision to exclude evidence because of inadequate foundation lies within the sound discretion of the trial court and will not be disturbed on appeal unless there was an abuse of discretion that affected substantial rights of the parties.
Swiontek v. Ryder Truck Rental, Inc.,
Whether or not an exhibit should have been excluded on the basis that it lacked •adequate foundation is primarily within the sound discretion of the trial court, the exercise of which will not be disturbed on appeal in the absence of a showing that it affected the substantial rights of the parties.
Id.
(citing
Ned Nastrom Motors, Inc. v. Nastrom-Peterson-Neubauer Co.,
[¶ 18] Piatz and Johnson attempted to introduce evidence concerning Dr. Fielden’s prior individual medical examinations through Austin Mutual’s previous attorney who handled their claim. The trial court excluded the document and refused to take judicial notice because Piatz and Johnson had not established a connection between Dr. Fielden’s answers to interrogatories and the testifying witness. We do not find this to be an abuse of discretion.
[¶ 19] Further, any harm caused to Piatz and Johnson was nullified by the inclusion of the evidence in Dr. Fielden’s deposition. Dr. Fielden did not testify at trial, but his deposition was received by the trial court. At his deposition, Piatz and Johnson were able to cross-examine him- with the information they tried to introduce at trial. The trial court was made aware of the number of individual medical examinations performed by Dr. Fielden and the amount of income he received.
V
[¶ 20] Piatz and Johnson argue Dr. Fielden was not qualified to express an opinion about whether chiropractic treatment was necessary. They claim Dr. Fiel-den acknowledged he had no training in the field of chiropractic treatment, yet the trial court gave full weight to his opinions.
[¶ 21] Whether a witness is qualified as an expert is within the sound discretion of the trial court, and will not be
*688
reversed on appeal unless that discretion is abused.
Myer v. Rygg,
[¶ 22] Dr. Fielden was asked to explain the conclusions he reached concerning the physical condition of Piatz and Johnson. Johnson and Piatz objected because Dr. Fielden was not a chiropractor and should not be allowed to comment about the necessity of any chiropractic treatment. We have explained that a witness need not be licensed in a given field to be an expert, so long as the witness possesses the requisite knowledge, skill, experience, training, or education in that field.
See Oberlander v. Oberlander,
VI
[¶ 23] Piatz and Johnson argue the trial court’s findings of fact are clearly erroneous. They challenge the following findings of fact: the small hot tub provided by Austin Mutual was sufficient to comply with Austin Mutual’s contractual obligation; a special mattress was not a reasonable or necessary medical rehabilitation expense for Johnson; a conversion seat was not a reasonable or necessary medical rehabilitation expense for Johnson; a treadmill was not a reasonable or necessary medical rehabilitation expense for Johnson; Piatz failed to disclose to her treating physicians her extensive medical history involving pain and treatment to the same areas of her body she claims were injured in the accident on July 2, 1997; no reliable medical opinions were submitted on behalf of Piatz connecting her claim for damages to the accident; and prior to May 26, 1998, Piatz and Johnson had recovered from any and all injuries she sustained in the accident of July 2,1997.
[¶ 24] We review the trial court’s findings of fact under the clearly erroneous standard set forth in N.D.R.Civ.P. 52(a).
Auction Effertz, Ltd. v. Schecher,
*689 In a bench trial, the trial court is “the determiner of credibility issues and we do not second-guess the trial court on its credibility determinations.” We do not reweigh evidence or reassess credibility, nor do we reexamine findings of fact made upon conflicting testimony. We give due regard to the trial court’s opportunity to assess the credibility of the witnesses, and the court’s choice between two permissible views of the evidence is not clearly erroneous.
[¶ 25] In its findings of fact, the trial court gave significant weight to Dr. Fiel-den’s conclusion that Piatz and Johnson had fully recovered from any injuries sustained in the accident on July 2, 1997. The trial court found no rehable medical opinions were submitted on behalf of Piatz because Piatz had failed to disclose to her doctors her prior medical history regarding pain and treatment to the areas injured in the accident on July 2, 1997. The trial court also noted Johnson had engaged in full and rigorous exercise and physical activity since the accident, including participating in track by throwing the discus and shot-put, lifting weights, running, doing gymnastics, playing basketball, and snowmobiling. These facts, combined with Dr. Fielden’s conclusions, support the trial court’s findings that a larger hot tub, a special mattress, a conversion seat, and a treadmill were not reasonable and necessary medical or rehabilitation expenses. After reviewing the evidence in this case, we are not left with a definite and firm conviction that a mistake has been made. We conclude the trial court’s findings of fact are not clearly erroneous.

[¶ 26] The judgment of dismissal is affirmed.
