In this garnishment proceeding, appellant appeals an order granting the Maughs’ (claimants) claim of exemption from garnishment. We affirm.
Many of the facts are not in dispute. Respondent Wittmayer, as personal representative of the estate of Alice Edwards, is vendor under a land sale contract (the contract) dated March 21, 1980. In May, 1988, appellant obtained a judgment against respondent for $5,500, plus costs. Appellant then served writs of garnishment on (1) L-S II, a partnership and successor to the vendee under the contract, and (2) Eugene Escrow Service, Inc. (the escrow). The answering certificate of L-S II stated that it owed $29,629.64 to respondent under the contract. The answering certificate of the escrow stated that it maintained a collection escrow for respondent for the monthly contract payments. With the answering certificate, the escrow remitted $200.02 of collected funds.1
Claimants then filed a claim for exemption. See ORS 23.168; ORS 29.142. They relied on two documents that they assert were assignments of the payments that the escrow received on the contract: (1) a letter, dated July 31,1980, from Lofgren, respondent’s predecessor as personal representative, to the escrow that instructed it to make all payments that it received under the contract to Charles L. Edwards (Edwards) “until further notice from me;” and (2) a letter, written in January, 1981,2 from Edwards to the escrow that instructed it to send payments that it received under the contract to claimants “until such time as they and I notify you to make payment again to me or to someone else.” Pursuant to the letters, the escrow, since 1980, has forwarded payments, first, to Edwards and later to claimants.3 After a hearing, the court *139allowed the claim of exemption without limitation.
Appellant asserts that the court erred when, according to appellant, it ruled that the letters “constituted an assignment of future payments with respect to the contract” and when it allowed the claim of exemption. She does not dispute that, if Lofgren made an assignment, that assignment binds respondent as her successor in interest. Appellant’s principal argument is that, because the letter from Lofgren to the escrow contained the words “until further notice from me,” Lofgren did not intend the letter to be an assignment of the payments that the escrow received. Appellant concedes that the letter from Edwards to the escrow “appears to be more like an assignment,” but asserts that Edwards could not assign greater rights to claimants than he had acquired under the Lofgren letter. The court ruled that the letters were assignments and that, because there was no evidence of “further notice” from Lofgren or Edwards, they continued to be effective.
A present and binding appropriation of an interest in a specific fund is an assignment. Wakefield, Fries & Co. v. Parkhurst, 84 Or 483, 486, 165 P 578 (1917); Levins v. Stark, 57 Or 189, 191, 110 P 980 (1910). It
“may be oral or written and no special form is necessary provided that the transfer is clearly intended as a present assignment of the interest held by the assignor.” Anderson v. Dept. of Justice, 38 Or App 29, 32, 588 P2d 1295 (1979).
Here, the letters describe the specific fund — payments that the escrow would receive from the vendee under the contract. See Morris v. Leach, 82 Or 509, 511, 162 P 253 (1917). The letters instructed the escrow to make payments to third persons from that fund. Appellant does not dispute that the letters imposed that duty..4 The escrow followed the successive instructions of Lofgren and Edwards. The court interpreted *140Lofgren’s letter as an assignment to Edwards. It also interpreted Edwards’ letter as an assignment to claimants.5 We agree with the court’s interpretations. It is not clear whether appellant also asserts that Lofgren’s letter is not an assignment because it is revocable, but that assertion would be without merit. See Restatement (Second) Contracts § 331 (1981). Lofgren’s use of the language “until further notice from me” cannot be viewed in isolation and is not by itself sufficient to negate an intention to assign. As to Edwards’ letter, it instructed the escrow to make payments to claimants “until such time as they and I notify you to make the payment again to me or to someone else.” Without claimants’ concurrence, Edwards could not have instructed the escrow to cease making payments to claimants. The court did not err in concluding that both Lofgren and Edwards made assignments.6
Appellant also assigns as error that the court did not limit claimants’ exemption to $3,800. The court did not err.7
