Braucher, J.

The plaintiff’s land was taken by the defendant by eminent domain, and later a pro tanto payment was made. G. L. c. 79, § 8A. The plaintiff claims interest on the amount of the pro tanto payment from the date of taking until the date it received notice that the payment was available to it. The defendant claims that no interest was owed for this period because the payment could not be made until the plaintiff obtained a release of a lease on the premises. A j'udge of the Superior Court awarded the plaintiff the interest it claimed, and we affirm.

*500The facts are stipulated. The plaintiff’s right to damages vested on February 14, 1968, when the defendant’s order of taking was recorded. In March, 1968, the defendant wrote to the plaintiff’s counsel that pro tanto payment could not be made until a lease of the premises was released or terminated. The plaintiff was a wholly owned subsidiary of the lessee, and both were represented by the same attorney. In January, 1969, the defendant received an affidavit that the lease had been terminated, and on January 29, 1969, the plaintiff received notice that a pro tanto payment of $200,000 was available to it. The payment did not include interest from February 14, 1968, to January 29, 1969. In the plaintiff’s action for the assessment of damages, the judge awarded interest on the $200,000 for that period.

There was no error. Just compensation includes interest from the date of taking to the date of payment. G. L. c. 79, § 39. Woodworth v. Commonwealth, 353 Mass. 229, 231-233 (1967), and cases cited. Under G. L. c. 79, § 8A, the taking authority may stop the running of interest by making a pro tanto payment or offer. “The purpose of a pró tanto payment is merely to prevent the accumulation of interest on the amount of the offer and to provide funds for the recipient of the offer without waiting for a final adjudication.” The statute does not require “that interest on the amount of the pro tanto offer be included in order to make the offer valid.” Horne v. Boston Redevelopment Authority, 358 Mass. 460, 464 (1970). In the computation of damages the owner is “entitled to have the clerk compute and add to the amount of the verdict interest ... on the amount . . . [offered] from the date of the taking ... to the date of the receipt of the pro tanto offer, and interest ... on the difference . . . between the amount . . . [offered] and the amount of the verdict . . . from the date of the taking ... to the date of the verdict . . . .” Id. at 465.

The defendant argues that it could not safely pay a landlord when it had notice of a lease. Universal Con*501tainer Corp. v. Cambridge, 361 Mass. 58, 61 (1972). That risk seems minimal when the landlord is a wholly owned subsidiary of the tenant and both are represented by the same attorney. Cf. Lowell Housing Authority v. Save-Mor Furniture Stores, Inc., 346 Mass. 426, 430-431 (1963). The defendant could have apportioned the damages under G. L. c. 79, § 6. See Kahler v. Marshfield, 347 Mass. 514, 518 (1964). Or it could have paid the money to the clerk of the Superior Court for deposit in an interest-bearing account. G. L. c. 79, § 7D, as amended through St. 1967, c. 476, § 1. In any event, to stop the running of interest under G. L. c. 79, § 8A, the defendant must comply with the statute. Apart from the statute, it is not important to determine who caused delay in payment. Dodge v. Rockport, 199 Mass. 274, 278 (1908).

Judgment affirmed.
