Defendant appeals the trial court’s grant of summary judgment for plaintiffs.
The following undisputed facts were presented at the summary judgment hearing:
Prior to August 1994, plaintiffs (hereinafter collectively “Whiteco”) owned an outdoor advertising sign which was located adjacent to Interstate 95 on land owned by the J.W. Crew estate (“Crew estate”). In 1972, the Department of Transportation (“DOT”) issued an advertising permit for the sign. In July, August and September, 1993, in anticipation of its pending purchase of the Crew *623estate land on which the sign was located, the DOT wrote Whiteco and offered to pay for the sign’s removal. Whiteco rejected the DOT’S relocation offer and refused to move the sign.
By deed recorded 24 February 1994, the DOT purchased part of the Crew estate land, including the land on which the sign was located, in order to construct a Welcome Center. In March, June, and July 1994, the DOT again wrote Whiteco and warned that it would remove the sign if Whiteco did not do so. In August 1994, Whiteco’s sign was moved during construction of the Welcome Center.
On 27 October 1994, Whiteco filed a complaint for inverse condemnation against the DOT. Both parties filed motions for summary judgment on the issue of the DOT’s liability to pay just compensation. On 24 October 1995, Judge Cy A. Grant, Sr. granted Whiteco’s motion for partial summary judgment. The DOT appeals.
We first note that the trial court’s order, although interlocutory, is immediately appealable under N.C. Gen. Stat. section l-277(a) because it affects a substantial right of appellant DOT. See City of Winston-Salem v. Ferrell, 79 N.C. App. 103, 107, 338 S.E.2d 794, 797 (1986).
The DOT contends that the trial court erred by ruling that it must pay Whiteco just compensation for its purported leasehold interest and its sign. We agree.
[1] We first address plaintiff’s contention that it is entitled to just compensation under N.C. Gen. Stat. section 136-111. This statute provides a remedy for persons whose “land or compensable interest therein” has been taken by the DOT when the DOT has not filed a complaint or declaration of taking. G.S. § 136-111 (1993). We find that plaintiff is not entitled to recover under this statute because it has failed to show that it had an interest in land that was taken.
Whiteco asserts that it had a leasehold interest in the land on which its sign was located at the time the sign was removed. We disagree. There are no recorded leases between the landowners and Whiteco regarding Whiteco’s placement of its sign on the Crew estate land. There is an unrecorded document purporting to be a lease, designated as a “Sign Location Lease.” This document states, on its face, that it is for a period of five years. It was signed by the Honorable W. Lunsford Crew, the executor of the Crew estate, on 8 March 1991, but not by Whiteco, and was never recorded.
*624After Mr. Crew signed the “Sign Location Lease,” Whiteco and Mr. Crew then agreed to incorporate by reference the terms of a 11 March 1991 letter from Mr. Crew to Whiteco into the “Sign Location Lease.” In this letter, Mr. Crew stated that the property was under an option to purchase and that, if the purchase went forward, the owners of the Crew estate land would not execute the “Sign Location Lease.” In the letter he also stated that, if the property was not sold, he and the other landowners would continue the lease at $300 per year for a period of five years. However, he further stated that they would only agree for the lease to be “on a month-to-month basis” but that they “would try to give at least ninety days’ notice” of termination if the property was sold. On the record before us, it appears that the property was not sold pursuant to the option mentioned in this letter and that on the first day of January of 1992, 1993, and 1994, Whiteco paid, and the owners of the Crew estate land accepted, a payment of $300 rent.
Whiteco asserts that, according to these terms, it had a five year lease enforceable against the DOT. Pursuant to N.C. Gen. Stat. section 47-18, a lease of land for more than three years is not valid to pass title as against a purchaser for valuable consideration unless it is recorded. Bourne v. Lay & Co., 264 N.C. 33, 36, 140 S.E.2d 769, 770-71 (1965). Since the 1991 “Sign Location Lease” purports to be for five years and was never recorded, it is not valid to pass title to Whiteco as against the DOT, a purchaser for value. Thus, at the time Whiteco’s sign was removed, Whiteco did not have an enforceable five-year leasehold interest in the property.
In fact, the record evidence shows that, regardless of the actual term of the lease between Whiteco and the owners of the Crew estate land, it was terminable by agreement, at most, on ninety days notice. Assuming for the sake of argument that the DOT succeeded to the previous owners’ lessor obligations, then the DOT also succeeded to the previous lessors’ right to terminate on ninety days notice.
The undisputed facts of record show that, prior to and after purchasing the property, the DOT satisfied this ninety days notice requirement. On 1 January 1994, Whiteco paid, and the owners of the Crew estate land later deposited, its $300 rent. The DOT’S deed of purchase was recorded on 24 February 1994. On 29 March 1994, more than 90 days prior to the actual removal of the sign in August 1994, the DOT notified Whiteco that it must remove its sign. We conclude that the notice given by the DOT effectively terminated any purported *625lease that Whiteco may have had with the DOT by virtue of the DOT’s purchase of the property.
Thus, at the time the sign was removed, Whiteco did not have a leasehold interest in the land on which its sign was located and was not entitled to exhibit its sign there. Whiteco was given a reasonable time to remove the sign. By not doing so, it effectively abandoned its sign. See 51C C.J.S. Landlord and Tenant § 317(b) (1968). We conclude that the DOT’s alleged subsequent removal of the sign in August 1994 did not entitle Whiteco to just compensation under G.S. section 136-111.
Whiteco further asserts that the DOT is obligated to pay just compensation for removal of its sign as a “taking” under our federal and state constitutions.
Whiteco asserts that the DOT was required to purchase its sign when it exercised its powers of eminent domain by purchasing the land on which the sign was located. To support its assertion, Whiteco relies on United States v. General Motors Corp., 323 U.S. 373, 89 L. Ed 311 (1945), and Advertising Co. v. City of Charlotte, 50 N.C. App. 150, 272 S.E.2d 920 (1980).
[2] In both of these cases, the complainant had an interest or alleged interest in the land being condemned and its personal property was damaged as a result of the removal necessitated by the condemnation. See General Motors Corp., 323 U.S. at 375, 383-84, 89 L. Ed. at 317, 321; Advertising Co., 50 N.C. App. at 153-54, 272 S.E.2d at 922. Here, in contrast, the evidence establishes that when its sign was removed, Whiteco did not have an interest in the land on which its sign was located. Even if the DOT did purchase the Crew estate land under threat of condemnation, neither General Motors Corp. nor Advertising Co. require a government entity which purchases land in this manner to pay just compensation for removable personal property located on the land when the owner of the personal property has no interest in the real property purchased.
[3] Whiteco also asserts that it did have an interest in land because its sign was realty, not personal property. We disagree. The undisputed record evidence establishes, as a matter of law, that Whiteco’s sign was removable personal property and not part of the realty. Here, the DOT purchased land which was the subject of a purported lease between Whiteco and the owners of the Crew estate land. When the rights of a third party purchaser are concerned, the issue of *626whether property attached to land is removable personal property or part of the realty is determined by examining external indicia of the lessee’s “reasonably apparent” intent when it annexed its property to the land. Little v. National Service Industries, Inc., 79 N.C. App. 688, 693, 340 S.E.2d 510, 513 (1986).
Here, Whiteco’s intent that its sign remain its personal property became reasonably apparent to the DOT when it purchased the Crew estate land, as indicated by external evidence of this intent. During the negotiations between the owners of the Crew estate land and the DOT, the landowners signed a disclaimer of any ownership interest in Whiteco’s sign. At this time, Whiteco had listed the sign as its personal property for tax purposes. The DOT permit for the sign was not issued to the landowner but to White Advertising Int., the entity which applied for the permit in 1972. Whiteco’s logo was displayed on the sign pursuant to N.C. Gen. Stat §. 105-86(e) which requires that the owner’s logo be displayed on the sign. In addition, we note that Whiteco has admitted, in its response to the DOT’S First Request for Admissions, that the sign was a “trade fixture” which by law is removable personal property. See Taha v. Thompson, 120 N.C. App. 697, 703, 463 S.E.2d 553, 557 (1995), disc. review denied, 344 N.C. 443, 476 S.E.2d 130, 131 (1996).
Once the DOT purchased the land where Whiteco’s sign was located, it had the right as a property owner to exclude others from use of the property. As the owner of the sign, once its right to exhibit the sign on DOT land under a lease agreement had expired, Whiteco was required to move it within a reasonable time. Whiteco had ample opportunity to do so but refused. By refusing to remove its sign within a reasonable time after termination of the tenancy, Whiteco effectively abandoned the sign. See 51C C.J.S. Landlord and Tenant § 317(b). By removing the abandoned sign, the DOT was simply exercising its rights as a property owner and was not proceeding pursuant to its power of eminent domain. Given these facts, we hold that Whiteco is not entitled to just compensation for its sign.
Whiteco also contends that 23 U.S.C. § 131 et. seq. and N.C. Gen. Stat. section 136-126 et. seq. require the DOT to pay just compensation for its sign. We disagree.
[4] In 1967, North Carolina adopted the Outdoor Advertising Control Act (“OACA”), codified at N.C. Gen. Stat. section 136-126 et. seq., in response to the federal Highway Beautification Act, 23 U.S.C. § 131 et. seq. (“HBA”) which imposes a reduction in federal funding for *627highway projects on any state which fails to provide for effective control of outdoor advertising. See 23 U.S.C. § 131(b) (1990). The OACA authorizes the DOT to acquire by purchase, gift, or condemnation all outdoor advertising and all property rights pertaining to the advertising which are prohibited under certain provisions of the OACA. N.C. Gen. Stat. § 136-131 (1993). However, the OACA does not expressly require the DOT to exercise this power.
In fact, no provision of the OACA expressly requires the payment of just compensation for signs removed by the DOT. Granted, this Court has previously stated that the OACA requires compensation to sign owners whose signs are removed pursuant to the OACA. See Givens v. Town of Nags Head, 58 N.C. App. 697, 700-701, 294 S.E.2d 388, 390, appeal dismissed and cert. denied, 307 N.C. 127, 297 S.E.2d 400 (1982). However, since this language in Givens was not necessary to this Court’s decision, it is obiter dictum and not binding. See Trustees of Rowan Tech. v. Hammond Assoc., Inc., 313 N.C. 230, 242, 328 S.E.2d 274, 281 (1985).
If the General Assembly had intended to require payment of compensation whenever the DOT removes a sign under the OACA, it could have used the term “required” rather than “authorized” in G.S. section 136-131. It did so in another provision, G.S. section 136-131.1., inapplicable here, where it specified that a local unit of government which removes outdoor advertising adjacent to certain highways, when the DOT has issued a permit for the advertising, must pay just compensation. See N.C. Gen. Stat. § 136-131.1 (1993).
Be that as it may, assuming for sake of argument that the DOT is required under the OACA, as stated in Givens, to pay just compensation for signs it removes, this requirement only applies when the DOT removes the sign pursuant to exercise of its regulatory power under the OACA. This is not what occurred here. In removing Whiteco’s sign, the DOT acted as a property owner, i.e., it removed an abandoned sign from property which it owned and in which Whiteco had no property interest. Given these facts, we conclude that the OACA does not require the DOT to pay compensation for Whiteco’s sign.
[5] We also disagree with Whiteco’s assertion that the federal HBA requires the DOT to pay compensation for removal of its sign. As we stated in Givens, the HBA does not create individual rights and does not impose regulation, but simply authorizes federal-state agreements pursuant to which state regulatory statutes, e.g., the OACA, *628may be adopted. Givens, 58 N.C. App. at 703, 294 S.E.2d at 392. If the OACA needs to be amended to comply with federal specifications regarding payment of compensation and therefore to assure continued availability of federal funding for state highway projects, this is a matter for the General Assembly, not for this Court. See id. at 701, 294 S.E.2d at 391. The DOT is not legally required to comply with the HBA, only with the OACA.
[6] We further reject Whiteco’s assertion that 42 U.S.C. § 4652 requires that the DOT pay just compensation for its sign. Our appellate courts have not addressed this issue. However, other state courts have held that this federal statute does not create a right to just compensation for signs where a state’s case law precludes compensation on the grounds that the signs are removable personal property. E.g., Matter of Condemnation by Minneapolis Community Dev. Agency, 417 N.W.2d 127, 131 (Minn. Ct. App. 1987), review denied (February 24, 1988) (citing Creative Displays v. South Carolina Highway, 248 S.E.2d 916 (S.C. 1978)). We agree with this approach. As discussed above, under North Carolina law, Whiteco’s sign is removable personal property. We hold that 42 U.S.C. § 4652 does not entitle Whiteco to compensation for its sign.
The trial court erred by granting summary judgment to Whiteco. We reverse and remand for entry of summary judgment in favor of the DOT.
Reversed and remanded.
Judges JOHNSON and WYNN concur.
