Land patent searches can be performed at the Bureau of Land Management's website, found here: https://glorecords.blm.gov/search/default.aspx. In the event there is a patent, the patent document is available to you on the site. If there is a patent, you'll also want to order the Land Entry Case File from NARA.
As mentioned by the previous reply, the patent itself can be viewed under “Patent Image” and the “Related Documents” tab may have additional documentation.
To obtain the “Land Entry File” from the National Archives you may download and fill out a NATF Form 84 and mail it to the address listed on the form or submit your order via eservices.archives.gov. We suggest using online ordering to expedite your request as electronic orders will be received and entered into their system more quickly.
If you have any additional questions about the records or the ordering process, please contact the National Archives at Washington, DC - Textual Reference (RR1R) Archives1reference@nara.gov.
