Okla. Stat. tit. 59, § 59-46.34: Seal of landscape architect

A. Each landscape architect shall have a seal, the image of

which shall contain the name of the landscape architect, the

person's license number and the words "Licensed Landscape Architect,

State of Oklahoma". All technical submissions prepared by such

landscape architect, or under the responsible control of the

landscape architect, shall be sealed, signed and dated, which shall

mean that the landscape architect was in responsible control over

the content of such technical submissions during their preparation

and has applied the required professional standard of care. No

landscape architect may sign or seal technical submissions unless

they were prepared by or under the responsible control of the

landscape architect, except that:

1. The person may sign or seal those portions of the technical

submissions under the responsible control of persons who are

licensed under the State Architectural and Licensed Interior

Designers Act if the landscape architect has reviewed and adapted in

whole or in part such portions and has either coordinated their

preparation or integrated them into the work; and

2. The person may sign or seal those portions of the technical

submissions that are not required to be prepared by or under the

responsible control of a landscape architect if the landscape

architect has reviewed and adapted in whole or in part such

submissions and integrated them into the work. The seal may be a

rubber stamp or may be generated electronically pursuant to rules

adopted by the Board.

B. All drawings, specifications, plans, reports or other papers

or documents involving the practice of landscape architecture, shall

be dated and bear the signature and seal of the landscape architect

or landscape architects who prepared or approved them. It is

permissible to only sign, seal and date documents on the first sheet

of bound sets of drawings, with index of drawings included, title

page of specifications, and other drawings and contract documents in

a manner consistent with this act and rules of the Board.

C. The seal, signature and date of the landscape architect may

be applied to tracings to produce legible reproduction of the

drawings or to reprints made from the tracings. This provision,

however, does not in any manner modify the requirements of the other

subsections of this section.

D. The license of a landscape architect shall not permit the

practice of architecture, engineering or land surveying, except that

which is incidental, meaning less than ten percent (10%) of the

total cost of the total project, to the practice of landscape

architecture. No landscape architect shall permit his or her seal

to be affixed to any plans, specifications or drawings if such

portions thereof as are involved in the practice of his or her

particular profession were not prepared by or under the landscape

architect's responsible control.
