In Docket No. 177495, plaintiffs Frederic H. and Lois K. Schadewald appeal by leave granted the trial court order denying their motion for summary disposition and granting defendants Phillipe and Sharon Brules' and Ross Township's motions for summary disposition pursuant to MCR 2.116(0(10). In Docket No. 187143, plaintiffs appeal by leave granted, raising additional issues regarding the trial court order. Defendants Philhppe and Sharon Brule have cross appealed the trial court's denial of their motion for sanctions. We affirm in part, reverse in part, and remand for further proceedings.
In 1951, Carl and Margaret Bauserman purchased a tract of land in Ross Township. In 1961, the Bausermans divided the property into two lots and sold the northern lot to plaintiffs. The Bausermans retained the southern tract, referred to as lot 341. Because lot 341 was landlocked, the Bausermans created a twenty-foot easement across the western edge of plaintiffs' property, connecting lot 341 to a right of way that provided access to a public highway. Lot 341 changed hands several times before it was purchased by the Brules in 1984. In 1989, the Brules purchased lot 539 from the Jennings family. Lot 539 consists of an additional acre of land adjacent to the western borders of lot 341 and plaintiffs' lot. For clarification, a diagram of the property is provided.
*792  This diagram is included in this opinion only to provide clarity with respect to the general layout of the land in question and the parcels contained therein. The boundary lines in the diagram are not precisely accurate, nor are they to scale.
Although there is a two-car garage attached to the Brules' house, it proved too small for their needs. In 1990, the Brules applied for a permit to build an additional garage on lot 539. The Brules' application was denied, however, because a zoning ordinance prohibited the construction of a building on a parcel of land with less than two hundred feet of frontage on a public roadway. On April 26, 1993, the Brules applied to the Ross Township Board of Zoning Appeals for a variance on the basis of practical difficulties. These difficulties included the facts that the township ordinance prohibited placement of an accessory building in their front yard, the steep terrain on the side of their house prevented locating the garage there, and placement on the Gull Creek side was hampered by the existence of a septic system and the fact that the structure would impair the adjacent property owners' view. Moreover, the Brules asserted that although lot 539 actually adjoins the right of way, an *793 extremely steep grade makes development impossible.
The Bruits' application was scheduled to be discussed at the board's public meeting on July 6, 1993. Plaintiffs sent the board a letter objecting to the issuance of a variance and requesting that discussion be postponed until the board's next meeting, because they would be out of the state on that date. Plaintiffs' request was denied. After addressing the Brules' application at the July 6, 1993, meeting, the board unanimously approved the variance on the condition that the Brules officially join lots 341 and 539 and move the centerline of their garage south so that it coincided with a hypothetical westward extension of the property line between lot 341 and plaintiffs' lot.
On July 14, 1993, plaintiffs filed a complaint in the trial court against the Brules and Ross Township. Plaintiffs claimed that the board erred in granting the variance and that the effect of the grant of the variance was an unconstitutional taking of their property. Plaintiffs sought to enjoin use of the easement on plaintiffs' property to provide the Brules with access to lot 539. The trial court issued a temporary restraining order. Plaintiffs subsequently sought to compel discovery and depose various board members regarding the July 6, 1993, meeting. Defendants objected that plaintiffs were improperly attempting to introduce evidence outside the record, although the township agreed to provide plaintiffs with the documents that the board had considered at the meeting. On September 28, 1993, the trial court dissolved the temporary restraining order, but warned the Brules that they proceeded at their own risk in constructing a garage on lot 539. Subsequently, the Brules built a garage on lot 539.
On April 6, 1994, the Brules moved for summary disposition pursuant to MCR 2.116(0(10) and for sanctions pursuant to MCR 2.114. On May 9, 1994, plaintiffs also moved for summary disposition pursuant to MCR 2.116(0(10), and on May 10, 1994, Ross Township did likewise. On June 3, 1994, a hearing was held on the parties' motions.
On June 27, 1994, the trial court rendered a bench opinion. The court held that the board's decision to grant the Brules a variance was supported by competent, material, and substantial evidence and represented a reasonable exercise of the board's discretion. The court conceded that the Brules' use of the easement to reach lot 539 constituted "a technical misuse of the easement." However, relying on two out-of-state cases, the court held that plaintiffs were not entitled to injunctive relief because there was no evidence of an increase in the burden on thenproperty, and therefore there existed no substantial and irreparable injury warranting injunctive relief. The trial court then granted defendants' motions for summary disposition and denied plaintiffs' motions for summary disposition and to compel discovery. In addition, the court denied the Brules' motion for sanctions. The order incorporating these decisions was entered on July 11, 1994.
In Docket No. 177495, plaintiffs applied for leave to appeal the trial court order affirming the board's grant of a variance to the Brules. On September 26, 1994, this Court granted plaintiffs' motion. In Docket No. 187143, plaintiffs filed a delayed application for leave to appeal additional issues relating to the substantive aspects of the case. The Brules cross appealed, challenging the trial court's denial of their motion for sanctions. On November 14,1995, this Court granted plaintiffs' delayed application for leave to appeal and ordered that the appeals be consolidated.

I
Plaintiffs first claim that the record of the July 6, 1993, hearing before the board was inadequate because the proceedings were neither transcribed nor tape-recorded. Plaintiffs contend that the trial court should have allowed them to question board members and other involved parties regarding what transpired at the hearing.
Following the hearing on plaintiffs' motion to compel discovery, the trial court directed the township to provide additional documents to plaintiffs to complete the record. On February 11, 1994, the township filed a "Revised Certificate of Record of July 6, 1993 Ross Township Zoning Board of Appeals Meeting." This consisted of the Brules' application *794 for the variance; five pages of site and building diagrams submitted by the Brutes; an affidavit of the township supervisor, with attachments; plaintiffs' June 30, 1993, letter to the board, with attachments; the Brutes' revised site diagram; several miscellaneous documents; the township's zoning ordinance; and the approved minutes of the July 6,1993, meeting.
M.C.L. § 125.289; M.SA § 5.2963(19) provides that a township zoning appeals board "shall maintain a record of its proceedings which shall be filed in the office of the township clerk and shall be a public record." Section 6.6 of the township's zoning ordinance requires a written record of the proceedings of each hearing before the board that must include "a summary of the proceedings, findings of fact, conclusions and the formal determination." The function of the trial court when reviewing the board's grant of a variance is to determine whether the decision was supported by competent, material, and substantial evidence on the whole record. M.C.L. § 125.293a(l); M.SA § 5.2963(23a)(l).
Plaintiffs' complaints regarding the sufficiency of the record, and in particular the record of the board's decision-making process, are not entirely unjustified. However, when viewed in light of the above standards, we conclude that the record is minimally adequate to permit judicial review. Plaintiffs have cited no authority to support their contention that a verbatim transcript of the proceedings must be made. Regarding plaintiffs' request to depose township officials about the basis for their decision, if the record of the board's proceedings is inadequate, the proper remedy is to remand for further proceedings before the board, not to depose board members. See M.C.L. § 125.293a(2); M.S.A § 5.2963(23a)(2). Furthermore, plaintiffs' argument that some of the information presented to the board was inaccurate does not render the record inadequate or the board's decision invalid.

II
Plaintiffs next question whether the board had the authority to waive the variance application requirements set forth in the township zoning ordinance. However, plaintiffs cite no authority in support of their
argument. This Court will not search for authority to support a party's position. Weiss v. Hodge (After Remand), 223 Mich. App. 620, 637, 567 N.W.2d 468 (1997). We therefore decline to review the issue.

III
Next, plaintiffs contend that the board abused its discretion in considering the Brule's' application for a variance because the application did not meet the requirements of the zoning ordinance. Plaintiffs maintain that they received inadequate notice of the variance request because the application did not mention the Brutes' residential lot or include any claims with regard to it.
We are unable to discern how plaintiffs were prejudiced by such omissions in the application. Although at the July 6, 1993, hearing the Brutes submitted more detailed drawings of the proposed structure, there is no prohibition against the board obtaining additional information on which to base its decision at a public hearing. Moreover, the substance of the Brutes' application was not altered by the additional data presented at the hearing. Plaintiffs had previously submitted their own map of the area, including the relationship of the proposed structure to their home. Plaintiffs did not exercise their right to send an agent to represent them at the hearing. See M.C.L. § 125.293; M.SA § 5.2963(23). Accordingly, we find no error requiring reversal.

IV

A
Plaintiffs next argue that the trial court erred in permitting the Brutes to use the easement across plaintiffs' lot to access lot 539. This is a question of law that we review de novo on appeal. Schroeder v. Detroit, 221 MichApp. 364, 366, 561 N.W.2d 497 (1997).
An easement is the right to use the land of another for a specified purpose. Bowen v. Buck & Fur Hunting Club, 217 MichApp. 191, 192, 550 N.W.2d 850 (1996). An easement does not displace the general possession of the land by its owner, but *795 merely grants the holder of the easement qualified possession only to the extent necessary for enjoyment of the rights conferred by the easement. Morrill v. Mackman, 24 Mich. 279, 284 (1872).
An appurtenant easement, which is the type of easement at issue in this case, attaches to the land and is incapable of existence separate and apart from the particular land to which it is annexed. See McClintic-Marshall Co. v. Ford Motor Co., 254 Mich. 305, 318-319, 236 N.W. 792 (1931). The land served or benefited by an appurtenant easement is called the dominant tenement. The land burdened by an appurtenant easement is called the servient tenement. Rusk v. Grande, 332 Mich. 665, 669, 52 N.W.2d 548 (1952). In the present case, plaintiffs' lot is the servient tenement and lot 341 is the dominant tenement.
Once granted, an easement cannot be modified by either party unilaterally. Douglas v. Jordan, 232 Mich. 283, 287, 205 N.W. 52 (1925); Tittiger v. Johnson, 103 MichApp. 437, 443, 303 N.W.2d 26 (1981). The owner of an easement cannot materially increase the burden of it upon the servient estate or impose thereon a new and additional burden. Delaney v. Pond, 350 Mich. 685, 687, 86 N.W.2d 816 (1957).
The trial court relied on Brown v. Voss, 105 Wash.2d 366, 715 P.2d 514 (1986), and Wetmore v. Ladies of Loretto, 73 Ill.App.2d 454, 220 N.E.2d 491 (1966). In both Brown and Wetmore, the courts held that misuse of an easement to benefit an added parcel of land may be overlooked when the increased burden is insubstantial. See Brown, supra at 372-373, 715 P.2d 514; Wetmore, supra at 466, 220 N.E.2d 491. However, while that may be the rule in other states, it is not the rule in Michigan.
In Barbaresos v. Casaszar, 325 Mich. 1, 37 N.W.2d 689 (1949), an easement existed for the benefit of lots B, C, and D. The plaintiffs owned lot B and an adjacent parcel, lot A. The defendant, who owned lot C, recognized that the plaintiffs had an easement appurtenant to lot B, but objected to the plaintiffs' use of the easement to benefit lot A. The Supreme Court held that where there was no easement by grant, reservation, way of necessity, or prescription, the burden on the servient estate could not be extended to an additional parcel. Id. at 7-8, 37 N.W.2d 689. The Court stated that "`"the servient estate is not to be burdened to a greater extent than was contemplated at the time of the creation of the easement."'" Id. at 8, 37 N.W.2d 689, quoting Bang v. Forman, 244 Mich. 571, 574, 222 N.W. 96 (1928), quoting Brossart v. Corlett, 27 Iowa 288 (1869).
A similar set of facts was presented in Soergel v. Preston, 141 MichApp. 585, 367 N.W.2d 366 (1985). The defendants owned parcel B, which was the dominant estate with regard to an appurtenant easement for the installation of utility lines across parcel A which was owned by the plaintiffs. The defendants also owned parcel C which adjoined parcel B. The defendants' residence was on parcel C. Parcel B was unoccupied. Id at 587, 367 N.W.2d 366. Controversy erupted when the defendants, over the plaintiffs' objections, installed a sewer line across parcels A and B to serve their house on parcel C.
This Court rejected the defendants' argument that the installation of the sewer line to parcel C did not materially increase the burden on parcel A The Court explained:
[T]he initial question in this case is whether parcel C has any right to an easement. Nothing in the easement agreement entitles the owners of parcel C to benefit from the easement appurtenant to parcel B. The question of whether parcel C's use of the easement constitutes a material increase would not arise until the future owners of parcel B decided to take advantage of the easement as well. Although defendants presently own both parcel B and parcel C, this could change in the future. The fact that only one parcel is benefiting from the easement, as contemplated by the easement agreement, is beside the point, because that is not the parcel for which the easement was intended. [Id. at 589, 367 N.W.2d 366.]
The Soergel Court upheld injunctive relief requiring the removal of the sewer line.
The Brules argue that they have not increased the burden on the easement. They point out that they are driving the same cars as before over the easement, but after traversing plaintiffs' property they are turning *796 right instead of left. However, the pertinent question is not whether the burden on plaintiffs' property has substantially increased, but rather whether lot 539 has any right to an easement over plaintiffs' property. See Barbaresos, supra at 7-8, 37 N.W.2d 689; Soergel, supra at 589,367 N.W.2d 366.
The record is devoid of any evidence that lot 539 has the right to an easement over plaintiffs' property, and in fact the Brules do not even claim that lot 539, standing by itself, is legally entitled to benefit from the easement.[1] The rights of an easement holder are defined by the easement agreement. Great Lakes Gas Transmission Co. v. MacDonald, 193 MichApp.; 571, 575, 485 N.W.2d 129 (1992). In the present case, the deed by which the Bausermans conveyed the northern portion of their property to plaintiffs states that the grant was "[s]ubject to a right of way over the Westerly portion thereof to connect with the right-of-way to M89."[2] The document does not mention any other parcel. Thus, as a matter of law, the easement does not extend to lot 539.
Even if the burden on plaintiffs' property were at issue, the Brules have not established that relief is unwarranted. The trial court found that travel over the easement was not materially increased by the use of the new garage. However, there is no empirical proof in the record that, despite the joinder of lots 341 and 539, an increased burden on plaintiffs' servient estate could not arise in the future. See Soergel, supra at 589, 367 N.W.2d 366. Contrary to Michigan law, the approach followed by the trial court affords the owner of the dominant estate carte blanche to unilaterally extend an easement to other property as long as he is careful not to increase the present burden on the servient estate. See Douglas, supra; Tittiger, supra. Accordingly, the trial court erred in denying relief to plaintiffs because there was no evidence of an increase in the burden on their property.

B
Plaintiffs assert that the trial court erred in denying their request to permanently enjoin the Brules from using the easement to reach lot 539. We review a trial court's decision whether to grant injunctive relief for an abuse of discretion. Senior Accountants, Analysts & Appraisers Ass'n v. Detroit, 218 MichApp. 263, 269, 553 N.W.2d 679 (1996).
When an injury is irreparable, the interference is of a permanent or continuous character, or the remedy at law will not afford adequate relief, a bill for an injunction is an appropriate remedy. Soergel, supra at 589-590, 367 N.W.2d 366. Activities by the owner of the dominant estate that go beyond the reasonable exercise of the use granted by the easement may constitute a trespass to the owner of the servient estate. Embrey v. Weissman, 74 MichApp. 138, 143, 253 N.W.2d 687 (1977). In the present case, the Brules' use of the easement to benefit lot 539 would constitute a continuing trespass for which damages would be difficult to measure. Accordingly, injunctive relief is the appropriate remedy, and the trial court abused its discretion in denying plaintiffs' request for an injunction. See Brown, supra at 374, 715 P.2d 514 (Dore, J., dissenting). We therefore remand this matter to the trial court with instructions to enter an injunction prohibiting the Brules from using the easement for the benefit of lot 539.
*797 We recognize that our decision places hardship on the Brulés.[3] However, they knew or should have known when they purchased lot 539 that the easement across plaintiff's property did not extend to that parcel. Furthermore, they went ahead with the construction of the garage on lot 539, although they were expressly warned that they did so at their own risk. Nevertheless, the Brulés are not without options: despite the difficulty, they can develop the part of lot 539 adjoining the right of way;[4] they can purchase additional land having easy access to the right of way or a public road; or they can negotiate with plaintiffs to obtain the right to use the easement to gain access to lot 539.

V
On cross appeal, the Brulés argue that the trial court erred in denying their motion for sanctions pursuant to MCR 2.114. The imposition of a sanction under MCR 2.114 is mandatory upon the finding that a pleading was signed in violation of the court rule or a frivolous action or defense had been pleaded. We review a trial court's decision regarding the imposition of a sanction to determine if it is clearly erroneous. The trial court's decision is clearly erroneous when, although there is evidence to support it, the reviewing court is left with a definite and firm conviction that a mistake has been committed. Contel Systems Corp. v. Gores, 183 Mich.App. 706, 710-711, 455 N.W.2d 398 (1990).
The Brulés contend that plaintiff's pleading was not well-grounded in fact because plaintiffs presented no evidence of an increased burden on their servient estate attributable to the Brulés use of the easement for access to lot 539. However, plaintiffs presented sufficient evidence to demonstrate that, contrary to Michigan law, the Brulés were unilaterally attempting to expand the easement. See Douglas, supra; Tittiger, supra. Indeed, as demonstrated by our discussion of the previous issue, plaintiffs' claim was meritorious. Accordingly, the trial court's denial of the motion for sanctions was not clearly erroneous.
Affirmed in part, reversed in part, and remanded for proceedings consistent with this opinion. We do not retain jurisdiction. No taxable costs pursuant to MCR 7.219, neither party having prevailed in full.
NOTES
[1]  The Supreme Court has stated that the servient estate is not to be burdened to a greater extent than was contemplated at the time of the creation of the easement. Barbaresos, supra. Defendants have submitted the affidavit of Carl Bauserman, in which he stated that when he created the easement he intended it to be used as reasonably necessary and convenient for the dominant parcel, including such uses as parking vehicles even if the garage were located on adjacent land. However, this does not demonstrate that Bauserman specifically intended to extend the easement to lot 539. In the deed conveying the northern portion of his property to plaintiffs, no mention is made of the easement benefiting any other pracels. On the facts in the record, it is unlikely that the Bausermans considered extending the easement to benefit lot 539, because at the time the easement was created, lot 539 was owned by Edmund and Dorothy Jennings as a small part of a large parcel of land that had adequate access to the public highway.
[2]  Although the specific language of the easement apparently refers to a twenty-foot strip at the western end of plaintiffs' property, because of both the slope of that area and the fact that it is covered with vegetation, the owners of lot 341 have always used a separate eleven-foot strip to gain access to their property.
[3]  As the Soergel panel noted, Michigan courts have granted injunctions in easement cases even harsher than that ordered in the instant case. See Soergel, Supra at 589-590, 367 N.W.2d 366 (requiring the disconnection of water and swer lines), Longton v. Stedman, 182 Mich. 405, 414-416, 148 N.W. 738 (1914) (ordering the defendants to tear down a brick building that obstructed the plaintiff's easement). Michigan courts have also upheld stringent relief in other property cases. See, e.g., Webb v. Smith (After Second Remand), 224 Mich.App. 203, 214, 568 N.W.2d 378 (1997) (requiring the defendants to demolish their house).
[4]  The Brules would not be entitled to an easement by necessity over plaintiffs' property because lot 539 is not landlocked as a result of the split from plaintiffs' lot, but rather by the split from the Jennings' parcel. See Goodman v. Brenner, 219 Mich. 55, 59, 188 N.W. 377 (1922). However, even if lot 539 had been created by splitting it from plaintiffs' lot, an easement of necessity would still not have arisen because lot 539 adjoins the right of way. The lack of any access except over a steep grade is insufficient to establish an easement by necessity. Waubun Beach Ass'n v. Wilson, 274 Mich. 598, 611-613, 265 N.W. 474(1936).
