The question before us is one of statutory interpretation. The fundamental canon of construction is to ascertain and give effect to the intention of the legislature. Varelis v. Northwestern Memorial Hospital, 167 Ill. 2d 449, 454 (1995). Courts will look first to the words of the statute (Metropolitan Life Insurance Co. v. Washburn, 112 Ill. 2d 486, 492 (1986)), for the language used by the legislature is the best indication of legislative intent (Kirwan v. Welch, 133 Ill. 2d 163, 165 (1989); County of Du Page v. Graham, Anderson, Probst & White, Inc., 109 Ill. 2d 143, 151 (1985)). When the statutory language is clear, no resort is necessary to other tools of interpretation. Henry v. St. John’s Hospital, 138 Ill. 2d 533, 541 (1990). Moreover, courts should not, under the guise of statutory construction, add requirements or impose limitations that are inconsistent with the plain meaning of the enactment. People ex rel. Le-Gout v. Decker, 146 Ill. 2d 389, 394 (1992); In re Estate of Swiecicki, 106 Ill. 2d 111, 120 (1985).
We believe the appellate court erred when it concluded that section 508 of the Marriage and Dissolution of Marriage Act is the sole means by which an attorney may recover a fee from a client in a domestic relations matter, to the exclusion of a common law action for contract damages, such as that brought in this case. A consideration of the statutory language, as well as of the practical difficulties that would result from the appellate court’s holding, persuades us that the legislature did not intend that result.
We find nothing in the plain language of the statute to indicate that the legislature intended that the remedy provided by section 508(a) would be an attorney’s sole avenue of recourse against a client, precluding any subsequent remedy brought after the termination of the underlying case. As this court stated in Kosicki v. S.A. Healy Co., 380 Ill. 298, 302 (1942), "Where * a new
