The defendant, the Town of Fremont (town), appeals the Superior Court (Perkins, J.) denial of its motion to release escrow funds from the sale of property it acquired by tax deed on which the plaintiff, Federal National Mortgage Association (FNMA), held a mortgage. We affirm.
The parties stipulated to the following facts. On February 14, 1991, the town acquired a tax lien on the property at issue for failure to pay the 1990 taxes. The lien was duly recorded at the Rockingham County Registry of Deeds, and both the record owner and mortgagee, Commonwealth Mortgage Company (Commonwealth), were notified of the lien by registered mail. See RSA 80:60, :65 (1991). On December 30, 1992, because the taxes remained unpaid, the town tax collector notified the record owner, in writing, that the town would issue a tax deed to itself if the taxes were not discharged by February 14, 1993. See RSA 80:77 (1991). The town's attempt to provide similar notice to Commonwealth by letter dated January 11, 1993, was unsuccessful. The letter was returned undelivered because Commonwealth had moved its offices, filed for bankruptcy, and did not have a current address on file with the postal service. At the time the town made its unsuccessful effort to provide notice to Commonwealth, it was unaware that Commonwealth had earlier assigned its interest in the mortgage to FNMA. FNMA did not record the assignment until February 12, 1993.
In June 1993, FNMA filed a petition for declaratory judgment seeking a determination of the parties' respective rights in the property. Shortly thereafter, the town and FNMA agreed to sell the property and place the proceeds of the sale in escrow pending our decision in First NH Bank v. Town of Windham, 138 N.H. 319, 639 A.2d 1089 (1994). After First NH Bank was decided, however, the town and FNMA disagreed about its effect on their dispute. On July 20, 1994, the town filed a motion to release escrow funds. Ruling that the undelivered notice to Commonwealth failed to "satisfy the third prong of the First NH Bank standard" and that "the Town failed to provide FNMA with all the notice due process requires," the trial court denied the motion. This appeal followed.
 The town argues that the trial court erred in ruling that the notices to both Commonwealth and FNMA were defective under First NH Bank. Because First NH Bank required the town to notify FNMA of the impending tax deed, we need not reach the town's argument concerning the notice to Commonwealth.
"We sustain the findings and rulings of the trial court unless they are lacking in evidential support or tainted by error of law." Public Serv. Co. of N.H. v. Town of Bow, 139 N.H. 105, 107, 649 A.2d 65, 66 (1994) (quotation omitted).
The town contends that the equity of redemption period expired on February 14, 1993, that it gave timely and adequate notice to Commonwealth, and that it did not learn about FNMA's mortgage interest until the following month. The town erroneously concludes that because it was entitled to issue a tax deed on February 14, 1993, it was free to ignore after-acquired information about FNMA's recorded assignment.
In First NH Bank, we held that a known mortgagee is entitled to actual notice of a tax deeding. First NH Bank, 138 N.H. at 327, 639 A.2d at 1094. Contrary to the town's position, RSA 80:76 (1991), which authorizes the tax collector to execute a tax deed "after 2
That the town fortuitously discovered FNMA's recorded assignment after February 14, 1993, did not relieve it of its legal obligation to provide notice to a known mortgagee of an impending tax deed. The statutory tax lien procedure at that time did not impose an obligation on the town to conduct a title search at or near the date it issued a tax deed, cf. White v. Lee, 124 N.H. 69, 76, 470 A.2d 849, 853 (1983), and, in fact, imposed no duty to search record title other than in conjunction with the actual tax lien notice. Compare RSA 80:65 (Supp. 1995) with RSA 80:77; but cf. RSA 80:77-a (Supp. 1995) (effective Jan. 1, 1996) (requiring title search for mortgages recorded at least thirty days prior to notice of tax deeding). Once the revealing search was conducted in March 1993, however, the town was then required to "provide the [mortgagee] all the notice required by the due process requirements of the New Hampshire Constitution." First NH Bank, 138 N.H. at 328, 639 A.2d at 1095.
