Written by Acorn Sales Company, manufacturing stamps and seals since 1964 · Reviewed by Holly R, VP of Sales and Marketing at Acorn Sales, against the Montana Board of Architects and Landscape Architects, within the Business Standards Division of the Montana Department of Labor and Industry and Mont. Code Ann. § 37-66-308(1), (2) on 21 September 2026 · Updated 21 September 2026
The seal goes on every drawing and on the title pages of specifications. Mont. Code Ann. § 37-66-308(2) requires all drawings and title pages of specifications prepared by or under the supervision of a landscape architect to bear the seal. Sheet by sheet for drawings, title page only for specifications. The same subsection then forecloses the obvious shortcut by stating that this seal cannot replace the seals of licensed architects, professional engineers or land surveyors.
The statutory content list is short: a seal approved by the board “that must contain the name of the landscape architect and the words ‘Licensed Landscape Architect, State of Montana’” plus such additional elements as the board determines. The license number is not a statutory element here, unlike the Montana architect seal at § 37-65-308, where the license number and the city and state of the place of business are both required by statute. Your number reaches the device, if at all, through the additional elements the board determines.
Ask the board for the approved design before ordering. Section 37-66-308(2) states no diameter, no shape and no device type, and any such detail sits in the board’s administrative rules at ARM Title 24 chapter 114, which is not published in readable form. Treat any quoted Montana landscape architect diameter as unverified unless the supplier can say where it comes from. Ours comes from our own bench: Acorn cuts this seal to a 1-5/8 inch circle carrying STATE OF MONTANA and LICENSED LANDSCAPE ARCHITECT.

Is a seal required in Montana?
Mont. Code Ann. § 37-66-308, headed Display of license and seal of landscape architect, does two jobs. Subsection (1) requires each license holder to display it “in the licensee’s principal office, place of business, or place of employment.” Subsection (2) requires each landscape architect to have “a seal approved by the board that must contain the name of the landscape architect and the words ‘Licensed Landscape Architect, State of Montana’” plus such additional elements as the board determines, and requires all drawings and title pages of specifications prepared by or under the supervision of a landscape architect to bear the seal. The same subsection states that the seal cannot replace the seals of licensed architects, professional engineers or land surveyors.
What must appear on the seal
- The words “STATE OF MONTANA” around one arc
- The words “LICENSED LANDSCAPE ARCHITECT” around the other arc
- Your place name in the center
- Your license number in the center
Two statutory elements and a board delegation. The statute does not name the license number as an element, which is different from the Montana architect seal at § 37-65-308, where the license number and the city and state of the architect’s place of business are both statutory. The number reaches a landscape architect device, if at all, through the additional elements the board determines. Ask the board for the approved design, because the statute conditions the seal on board approval and the board’s rules at ARM Title 24 chapter 114 is not published in readable form.
Size and shape
This is what Acorn actually makes for Montana, taken from our own production artwork rather than from a published rule. The Board’s administrative rules sit behind a verification gate we do not click through, so no published diameter could be quoted. What follows is the die we cut. The die is built to a 1-5/8 inch circle.
Embosser, rubber stamp or digital
Not addressed in any source we could obtain. The statute names no device: the words embossed, rubber stamp, facsimile, computer generated and electronic do not appear in § 37-66-308. Any device list would sit in ARM Title 24 chapter 114, which was unreachable as described in the size slot. Because the seal must appear on all drawings and on title pages of specifications, which are reproduced, order a physical inked stamp and confirm any electronic format with the board.
Signing and dating
Not addressed in the statute. Section 37-66-308(2) requires the seal on all drawings and title pages of specifications and states no signature requirement, no date requirement and no placement rule. The sources here are § 37-66-308 in full and the part 3 section list. Any signature or date rule sits in ARM Title 24 chapter 114, which was unreachable. Sign and date as a matter of practice.
Every drawing, the title page of the specifications, and no substitution
Mont. Code Ann. § 37-66-308(2) is more specific about placement than most landscape architecture statutes. The seal goes on all drawings and on title pages of specifications prepared by or under the landscape architect’s supervision. Sheet by sheet for drawings, title page only for specifications, and the statute then forecloses the obvious shortcut by stating that this seal cannot replace the seals of licensed architects, professional engineers or land surveyors.
Which documents must be sealed
All drawings and title pages of specifications prepared by or under the supervision of the landscape architect. Note what that means in practice: every drawing sheet, not a cover sheet alone, and the title page rather than every page of the specification. The statute also draws the boundary expressly, stating that the landscape architect’s seal cannot replace the seals of licensed architects, professional engineers or land surveyors. Section 37-66-301 requires a license to practice and § 37-66-302 addresses illegal use of the title.
Electronic and digital seals
Not addressed. MCA Title 37 chapter 66 contains no electronic or digital seal provision and names no technology, certificate authority or board-approved signing process. Whatever Montana requires of an electronic landscape architect seal sits in ARM Title 24 chapter 114, which was unreachable as described in the size slot. Treat any claimed Montana digital landscape architect seal standard as unverified.
Renewal, lapse and retirement
Not addressed. MCA Title 37 chapter 66 part 3 does not say what happens to the seal on expiration, suspension or revocation, whether the license number changes on reinstatement, or whether the device must be destroyed or surrendered. The sources here are the part 3 section list, §§ 37-66-301 through 37-66-323, noting that §§ 37-66-305, 306, 307, 321, 322 and 323 are repealed and that part 2, the former Board of Landscape Architects, is itself repealed with the profession now administered by the Board of Architects and Landscape Architects. Contrast the Montana engineer and land surveyor statute at § 37-67-314(4), which makes sealing after expiration unlawful in terms.
Firm requirements
Licensing is restricted to individuals with a partnership provision alongside. Mont. Code Ann. § 37-66-303 is headed Licensing restricted to individuals, partnerships, local business licensing. There is no certificate of authorization in chapter 66 and no firm seal, and the statute puts nothing about a firm on the face of the device. Any further entity requirement would sit in ARM Title 24 chapter 114, which was unreachable. Contrast Montana engineering and land surveying, where § 37-67-328 requires a certificate of authorization for a business entity registered with the Montana secretary of state.
What to check before you order
Ask the Board of Architects and Landscape Architects for the seal design it approves, because Mont. Code Ann. § 37-66-308(2) requires board approval and the board’s rules at ARM Title 24 chapter 114 is not published in readable form. The statute fixes your name and the words Licensed Landscape Architect, State of Montana, and leaves any further elements, including your license number, to the board. No diameter and no device are verified, so buy a physical inked stamp and confirm any electronic format with the board. Seal all drawings and the title pages of specifications you prepared or supervised. Remember the boundary the statute draws: your seal does not replace an architect, professional engineer or land surveyor seal, and Montana architects carry the city and state of their place of business on the face while you do not.

Frequently asked questions
Is a seal required for landscape architects in Montana?
Yes. Mont. Code Ann. § 37-66-308, headed Display of license and seal of landscape architect, requires each landscape architect to have a seal approved by the board and requires all drawings and title pages of specifications prepared by or under the supervision of a landscape architect to bear it. Subsection (1) separately requires you to display your license “in the licensee’s principal office, place of business, or place of employment.”
What has to appear on a Montana landscape architect seal?
Your name, the words Licensed Landscape Architect, State of Montana, and such additional elements as the board determines. The statute does not name the license number, which differs from the Montana architect seal at § 37-65-308. Ask the board for the approved design, because the statute conditions the seal on board approval. Acorn’s own production artwork carries STATE OF MONTANA on one arc, LICENSED LANDSCAPE ARCHITECT on the other, and the place name and license number in the center. That is what we cut, not a published specification.
What size is a Montana landscape architect seal?
The statute does not say. Section 37-66-308(2) requires a board-approved seal and prescribes no diameter, shape or proportion, and the rest of MCA Title 37 ch. 66 part 3 adds nothing. Any dimension would sit in ARM Title 24 chapter 114, which is not published in readable form, so take the figure from the board rather than from a supplier. Acorn’s own production artwork for this seal is built to a 1-5/8 inch circle. That is our production record rather than a published rule, so the board remains the authority if it later publishes a figure.
Which device should a Montana landscape architect buy?
The statute names none: the words embossed, rubber stamp, facsimile, computer generated and electronic do not appear in § 37-66-308. Because the seal must appear on all drawings and on title pages of specifications, which get reproduced, a physical inked stamp is the practical purchase, and any electronic format is a question for the board.
Does Montana require a signature and date with the seal?
Section 37-66-308(2) requires the seal and states no signature requirement, no date requirement and no placement rule. Any such rule sits in ARM Title 24 chapter 114. Sign and date as a matter of practice.
Which Montana documents have to be sealed?
All drawings and title pages of specifications prepared by or under your supervision. Every drawing sheet, not a cover sheet alone, and the title page rather than every page of the specification. Section 37-66-301 requires a license to practice and § 37-66-302 addresses illegal use of the title.
Can my Montana seal stand in for an architect or engineer seal?
No, and the statute says so directly. Section 37-66-308(2) states that the landscape architect’s seal cannot replace the seals of licensed architects, professional engineers or land surveyors. That boundary is worth quoting to a client who hopes one device will cover a whole submittal.
Is there an electronic Montana landscape architect seal rule?
MCA Title 37 chapter 66 contains no electronic or digital seal provision and names no technology, certificate authority or board-approved signing process. Whatever Montana requires sits in ARM Title 24 chapter 114, which was not readable for this page, so treat any claimed Montana digital landscape architect seal standard as unverified and ask the board.
What happens to a Montana seal on lapse?
Title 37 chapter 66 part 3 does not say what happens on expiration, suspension or revocation, whether the license number changes on reinstatement, or whether the device must be destroyed or surrendered. Sections 37-66-305, 306, 307, 321, 322 and 323 are repealed, and part 2, the former Board of Landscape Architects, is itself repealed, with the profession now administered by the Board of Architects and Landscape Architects. Contrast the Montana engineer and land surveyor statute at § 37-67-314(4), which makes sealing after expiration unlawful in terms.
Does a Montana landscape architecture firm need a certificate?
Chapter 66 has no certificate of authorization and no firm seal, and the statute puts nothing about a firm on the face of the device. Mont. Code Ann. § 37-66-303 is headed Licensing restricted to individuals, partnerships, local business licensing. Contrast Montana engineering and land surveying, where § 37-67-328 requires a certificate of authorization for a business entity registered with the Montana secretary of state.
