Share-based compensation arrangement by share-based payment award, description				On June 18, 2008, the Board of Directors of First United Corporation adopted a Long-Term Incentive Program (the "LTIP"). This program was adopted as a sub-plan of the Omnibus Plan to reward participants for increasing shareholder value, align executive interests with those of shareholders, and serve as a retention tool for key executives. Under the LTIP, participants are granted shares of restricted common stock of First United Corporation. The amount of an award is based on a specified percentage of the participant's salary as of the date of grant. These shares will vest if the Corporation meets or exceeds certain performance thresholds.
Deferred compensation arrangement with individual, description				Stock-based awards were made to non-employee directors in May 2015 pursuant to First United Corporation's director compensation policy. Beginning May 2014, each director receives an annual retainer of 1,000 shares of First United Corporation common stock, plus $10,000, all or some of which may be paid, at the director's election, in cash or additional shares of common stock.
